Installation

As with all electrical equipment, the appropriate specifications and practices governing installation must be followed when

power factor correction equipment is installed. Before removing the front nameplate to adjust the function or DIP switch,

always ensure that your body is not carrying any electrostatic charge. This can be accomplished by touching a groundedobject, such as the switchboard metal housing to dissipate any electrical charge before removing the nameplate.

1 Check that the measurement and control voltage, supply frequency and current transformer rating comply with the ratingsgiven on the back of the BLR-CX power factor controller.

2 Mount the relay in the panel by means of the two plastic retaining clamps: to remove the clamps from the instrument,

gently lift the tab away from the instrument body and it will slide off. To replace and tighten, slide in snugly.

3 The BLR-CX uses rear mounted terminal blocks featuring spring loaded connections that accept stripped wire directly (nocrimped lugs required), 12 AWG max. To the side of the actual connection is a small spring release lever that you pushdown to allow the wire to be placed in the connection. The lever is designed to fit a small flat blade screwdriver to be

used in the pushing action a 1/8 (3 mm) flat blade is suggested. Do not use excessive force on the spring release lever.

4 Please note the fuses shown on the wiring diagram: these are fuses that must be provided by you to protect the controller

and your panel wiring.

5 As you begin the wiring of your controller, the markings on the unit and the wiring diagrams will refer to the three phasesas L1, L2, L3 these correspond to A, B, C. Wire the controller in accordance with the wiring diagram. The correct

calculation of power factor requires that the wiring exactly follows the rotational direction of the three phases; this meansthat the L2 and L3 measurement connections as well as the CT (on L1) must be followed precisely. For example, if L2

and L3 are reversed or the CT is installed backwards, the controller will provide incorrect information and control outputswill be wrong or not operational.

Pay special attention to the wire size for the C.T. connections. We recommend that for runs up to 25 feet or 8

metres, 12 AWG should be used.

An integrated voltage detector monitors the supply voltage at N and L connections (identified as GRID connections onthe diagram) in BLR-CX and guarantees a safety-disconnection of the capacitors in the case where monitored voltage

drops below 70% of nominal. For this monitoring feature to be successful, the grid or supply voltage must be taken fromthe identical phase as control voltage for the contactors. The steel rear cover of the controller has a tab for grounding the

instrument to the switchboard insuring maximum safety.

6 Current connection of the controller is designed for current transformers with a secondary of either 5 A or 1 A. Selectable

CT ratios up to 4000 / 1 maximum may be programmed. Note, the CT ratio setting is only required for BLR-CX

controllers with the measurement display option M.

Set Up

This section is both a learning guide to let you know which parameters are adjustable and also a section to be used during thecommissioning function when you actually have power applied to the unit. Illimite Incorporated suggests that you review this

section now (before power up) and have it available as you initially set up and test the controller during commissioning.

Behind the removable nameplate on the front of the BLR-CX is a multifunction switch (H3) and 2 pushbuttons (+and-).

On units with option L(Fan Control) there is a bank of 2 additional DIP switches (S1/S2) fitted for selecting one of the four

temperature threshold levels to switch the fan control relay contact.

On units with option M(Measurement Display Functions) 2 touch pads are incorporated in the front panel for selecting and

displaying electrical values. These are also used in place of printed circuit board mounted switches (+and-) found on theBLR-CX controllers (without the M option) used for setting the various parameters for the multifunction switch (H3).

Altering or re-setting the controllers parameters is performed with power applied to N and L terminals of the BLR-CX and by

means of the +and -pushbuttons or touch pads after the multifunction switch position has been selected. Default parametersare set at the factory to facilitate commissioning the BLR-CX; default values are shown later in this section.

Please note:when you are changing settings, theselected values will only be stored in the BLR-CX if the multifunction

switch is placed back into position 3 again after the changes or changes are made and before power is removed!

Set Up section continues on the next page.

page 3

Multifunction Switch (H3) Positions 0 to 9 and A to F

0 Loss of capacitance value. The BLR-CX is removed from automatic operation in this position. Energized steps (if any)

will automatically be disconnected after 20 seconds. Use this switch position to set a threshold level where an alarm is

generated indicating that the capacitor step has lost value from the first level measured at start up. The setting is a

percentage of original value (original being 100%), therefore, set in a range of 10% to 60 %. using the +and buttons ortouch pads. This will provide an alarm condition when a capacitor step falls to your set percentage. Default value from thefactory is 50 %. The display indicates OFF alternating with50 for default setting. If you change this setting, yourvalue will alternately flash with OFF.

1 PF target set., This allows you to define your target PF (power factor). Set in the range from (inductive) 0.70 lag to 1.00

to (capacitive) 0.90 lead using the buttons or touch pads. Default value is cos = 1.00

2 Switching time delay. This allows you to set the delay time before the step control relays change state either turning onor off each element of the bank. Set a time delay for from 5 to 1200 seconds. Push the +or button successively for small

adjustments or continue holding the button for more than 2 seconds for rapid change. Default delay is 40 seconds.

3 Fully automatic control of the PF control system. This is the normal operating position for the switch. Display

indicates the existing power factor with either Ifor inductive (lagging) or cfor capacitive (leading) load. The display isupdated every 3 seconds. A flashing dot in the display above either the +or signs indicates that the BLR-CX is selecting

a suitable capacitor, if available, to correct the reactive power deviation that is measured at that moment.

Electrical parameters may be displayed with the switch in this position for controllers with the M option

4 Manual operation. Manual operation is possible providing that the L2 - L3 voltage is a minimum of 50 volts. By

alternately pushing either the + or the button, steps will be (respectively) activated or deactivated after the presetswitching time delay defined in switch position 2 has been allowed. Letter H will be displayed alternating with the actualPF measured at that time (H = 1 sec. PF = 5 sec.).

5 Selection of number of steps. Step limitation is set to match the number of elements in the bank of your PF correction

system. The digits after BLR-CX-xx indicate the maximum number available to you (i.e. BLR-CX-12 can control a

maximum of 12 steps). Set the number of steps only to the number of elements in your bank as alarms will be initiated bythe controller if the number is set higher than steps available (it will believe that the extra steps are not working). The

display will indicate CL 8 if you set the number of steps to 8, CL 12 if you set it to 12 and so on.

6 Automatic display of failed Capacitors. Use this switch position if you receive an AL alarm indication on the display

that is not related to the target PF not being met. This position will indicate the location of either failed capacitor steps or

relay / contactor outputs that have not correctly controlled the capacitor. Indication of Cd 05 alternating with Cd 09indicates, that steps 5 and 9 are failing. To reset any alarm press button +and simultaneously for greater than 20

seconds. When using this switch position, Cd 0 indicates that no step has failed. The BLR-CX will continue to operatein the automatic control mode while the switch is in this position.

7 Number of switching operations. The number of switching operations that each contactor has made is shown in thedisplay. For example OC 4 for 2 seconds then followed by 248. This indicates that contactor number 4 has completed

248 switching operations. Other contactors can be selected by using the + and -buttons. The BLR-CX accurately updatesthe number of switching operations to memory for each contactor after a total of 10 switching operations regardless of

which contactor switches during the batch of 10. The stored data of all steps can be cancelled by depressing the + and -buttons simultaneously for greater than 20 seconds. Of course, if you reset this, you will no longer have the historical datain the controllers memory.The BLR-CX will continue to operate in the automatic control mode while the switch is in

this position.

8 Indication of Step Sizes. The value indicated on the display is proportional to the step size, but it is not calculated in kVar

as the CT ratio is unknown (see exception below for models with the M option). It will be displayed, for example, asCC 10 for the 10thstep, followed by 2 numbers such as L 74 and F 84. Value F stands for the first sensed

capacitor size during commissioning and L for the last value that may be several months or years later. This allows you

to recognize any loss of capacity since the original commissioning of the BLR-CX and the compensation system. If the

selected threshold level value chosen when setting multifunction switch position 0 is not met due to a failed capacitor orblown fuse, the controller eliminates this step from control procedure and triggers alarm AL which is shown in thedisplay. The data for each step may be displayed by means of either + or button. If you wish to reset the stored data,

push buttons + and simultaneously for greater than 20 seconds. The controller learns each step value from the original

commissioning and updates the L value during regular operation. Of course, if you reset this, the original data is lost.BLR-CX controllers with the M option (display of measured values) will show the sensed capacitor sizes in actual kVar

as a CT ratio is programmed in order to display correct electrical values. See switch position D and also option M for

CT ratio set up.

9 Selection of Alarm Mode. This switch position allows selection of one of 3 different alarm modes on the controller:

(1) A_0 The A_0 selection disables all alarm functions and no alarm indicators will appear on the display.(2) A_1 This setting provides the alarm function with automatic reset when the alarm is no longer present.

(3) A_2 The A_2 setting is the alarm function with manual reset required after the alarm has cleared.

The mode selection of these three options is achieved by use of the +and pushbuttons or touch pads; you chose the

option that you require and turn the switch back to the 3 position for normal operation. All alarms, regardless of thesource will follow the mode that you select (see Alarms and also Options for the various alarm types).If you have set the BLR-CX in the A_2 position that requires manual reset, you will need to return the switch to this (the

9 position) to achieve reset. To reset, toggle the +and buttons to find position A_3 then push and hold the +for greater

than 5 seconds. The reset will be confirmed by a display of ArES. Release the + button and set the display to the A_2position to restore the manual reset mode, then return the switch to position 3 for normal operation.

There is one exception to the re-setting of manual reset alarms and that is the AL indicator associated with AutomaticDisplay of Failed Capacitors. For this alarm with the mode set for A_2 (manual reset), please use the reset procedure

defined under switch position 6.

A Selection of a 2ndPower Factor Target(available with option L only).

Set the second target PF in the same way as the primary target was set by you with multifunction switch position 1.Set in the range from (inductive) 0.70 lag to 1.00 to (capacitive) 0.90 lead using the buttons or touch pads.

The 2ndPF target will be activated by sending a control voltage of 150-240 V AC on terminals NT/NT1. The NT LED to

the right of the step indicator LEDs will be illuminated when the 2ndpower factor target is active.

B Selection of an asymmetrical Switching Time Delay. Selectable range of an asymmetric factor: 1 to 99 by means of

pushing touch pad or button +or -. Displaying, for example, Y_10multiplies the pre-selected switching time definedin switch position 2 by a factor of 10 for disconnecting steps (rapid switching in, slow switching out). Default value from

the factory is 1, indicating symmetrical switching time delay for both directions.

C Selection of a Lock Time at each Change of Switching Direction up or down. The BLR-CX includes a variable load

reversal lock-out time that is activated when switching direction changes from up to down or down to up. Adisplay of L_30means a lock time of 30 seconds before any switching function becomes effective. This lock time will

be added to the preset switching time delay set under switch position 2. This provides a reduction of the switching

operations with rapidly changing loads. Selectable range of lock time is 1 to 254 seconds. Factory default value is 30.

D Selection of CT (current transformer) Ratio(use only with option M)

Display indicates _not for units without option M. Only set this value if you do have the M option.

To set this parameter for the BLR-CX-xx-M or BLR-CX-xx-L-M, divide the primary value of the CT ratio by thesecondary (i.e. a 400 to 5 CT would be 400/5 = 80) and set this value (your equivalent of the 80) using the +and buttons or touch pads.Holding the button down for greater than 2 seconds advances the value rapidly. Maximum value

that can be programmed is 4000. The factory default is 100.

E Selection of PT (potential or voltage transformer) Ratio(use only with option M)Display indicates _not for units without option M. Only set this value if you do have the M option.

To set this parameter for the BLR-CX-xx-M or BLR-CX-xx-L-M, divide the primary value of the PT ratio by the

secondary (i.e. a 12000 to 120 PT would be 12000/120 = 100) and set this value (your equivalent of the 100) using the

+and buttons or touch pads.Holding the button down for greater than 2 seconds advances the value rapidly. Maximum

value that can be programmed is 350. The factory default is 1.

F Selection of Switching Program. There are 4 switching programs available (2 for three phase and 2 for single phaseapplication), use the +and buttons or touch pads to select the program you require. After any change of this parameter,first return the function switch to position 3 after which you must reset the controller by removing power for 1 minute

then reapply power. The BLR-CX is now ready to function with the chosen switching program. Programs as follows:

(1) Auto Fully automatic recognition of each capacitor size without fixed program; intelligent and automatic selectionof the suitable capacitor to achieve the preset power factor target with the minimum of switching operations. Use this

program on three phase PF systems (CT is on L1 and voltage connections are on L2 and L3).(2) 1 1 1 1: Fully automatic recognition of each capacitor size. Linear switching program upfrom 1 to 12 and down12

to 1 means FILO/LIFO (first in last out / last in first out). Use this program on three phase PF systems (CT is on L1 and

voltage connections are on L2 and L3).(3) EautIdentical to Auto, however use this on single phase connection where voltage connections are L1 and N.

(4) E111Identical to 1111, however use this on single phase connection where voltage connections are L1 and N.

Factory default is AUTO.

Please remember that after any changes have been made, you will need to return the multifunction switch back to position 3 beforeyou remove power in order to save your changes.

Commissioning

1 Apply the grid supply, measurement and control voltages. Connect the CT and only after it is connected, remove any

short circuit link. If the measurement voltage is taken from phase L1 to neutral (for single phase operation of the units

measurement function), please make sure that the appropriate switching program has been selected (see Set Up switchposition F). If your measurement is for 3 phase operation (voltage connections on L2 / L3 and CT on L1), the default

AUTO program should be left in place (only change the 3 phase program from Auto if you need FIFO/LIFO program).

The following are indications that you may see during the commissioning function:1) Display shows IO This indicates that no current is f lowing from the secondary of the CT (a minimum of 10 mA

is required for the BLR-CX to be operational). If any capacitors had been energized before, these steps will bedisconnected after 5 minutes (this is possible when parallel operation of capacitor banks is in use). If the controller is set

to manual mode, any active steps continue to be active.

2) Display shows U0 This indicatesthat the measurement voltage is below 50 V or not connected.Later, when the BLR-CX is placed in switch position 3, it will start to control automatically if the measurement voltage is

50 V or above and reactive component of CT output is 10 mA or greater.

If the measurement voltage drops below 50 V, any energized steps will be switched off after a delay of 2 secondsregardless of whether the unit is in automatic or manual mode. For now, place multifunction switch in position 0(OFF).

2 This is a reminder of the factory default values as previously stated in the Set Up section:Capacitor percentage level that triggers alarm condition due to deterioration of capacitance over a period of time = 50%.

Power factor target = 1.0; switching time delay 40 seconds; step limitation to the BLR-CX-xx maximum set to numberof steps available; alarm mode = A-1; asymmetrical switching time factor = 1; load reversal lock time = 30 seconds;

CT ratio = 100; PT (VT) ratio = 1.0; switching mode = AUTO for standard 3 phase measurement (voltage on L2 / L3 and

CT on L1). Any value changes are performed by the multifunction switch (H3) and push buttons +or -as described in theSet Up section. You can verify each setting by rotating the multifunction switch and the present set up value will be

displayed. Do not forget to return the switch to Auto (position 3) when finished to save any new values. The factorydefault values have been installed in the controller to get a new system commissioned quickly but of course these valuescan be changed at any time during commissioning or as the system is in use and conditions require new values. If you

changed then saved (position 3) new values at this time, return the multifunction switch back to position 0(OFF) now.

3 In item #1or #2 of this section, you placed the multifunction switch to position 0(OFF); with power connected and the

switch in this position, the display will indicate an alternating message of OFF and 50. This is the default setting of

capacitor deterioration percentage to trigger an alarm. If you require a different percentage, change it now by the

instructions found in Set Up switch position 0. After any change has been made in the value, move the multifunctionswitch to position 3 the Automatic mode; this saves the new value ** or retains the default if no change was made.

4 With the switch now in position 3, a no volt release lock time of 90 seconds will be in effect before the BLR-CX starts tocontrol the PF compensation system. During this period steps will not be activated. After the lock time expires, you may

have action from the controller depending on your electrical system condition with regard to PF or how you have set up

your system test. You are now ready to confirm (or change) the rest of the adjustable parameters of the unit.

5 Check preset power factor target in position 1and select new value if required. Save it if you change it. **

6 Check preset switching time delay position 2and select new value if required. Save it if you change it. **

7 Check preset step limitation and if required, change to the real number of connected capacitors via switch position 5.

If any relay output, related contactor or capacitor controlled by the BLR-CX does not effect the PF compensation aswould be expected during normal operation (not necessarily an immediate effect during commissioning), it will be

recognized. The controller tests each non-performing step 3 times to confirm that it is inoperative and will lock this step

out for 1 day; a removal of power or an unintentional power failure will reset the knowledge that the step is inoperativeas will a reset initiated through the actions performed at switch position 6. After any of these events, the previously

inoperative steps will be checked again (3 times each). If they are inoperative, they will be recorded as alarms and

displayed as AL. If you made a change in this switch positions value save it.**

8 Check preset alarm mode using switch position 9to confirm it is correct; select new value if required then save it.**

9 Set back the multifunction switch into position 3and the BLR-CX will start normal automatic operation.

10 Display indicates the current power factor cos phi for example. l0.87for inductive or c0.94for capacitive load.

11 With all wiring checked for accuracy, the multifunction switch in position 3, the various parameters set correctly and the

no volt release lock time being completed, now apply an inductive load to the system. A dot in the display will begin toflash above the + sign.

**As you change values with the multifunction switch, you can either save changes one at a time by going back to switchposition 3 each time or make several changes and then go to position 3 before you remove power.

12 The BLR-CX controller will start to energize each step one by one in order to achieve the power factor target. A delay

between the initiation of steps will be noted as the selected value for the switching time delay is applied before each step

is started. LED`s below the main display will indicate the activated steps. Each step must influence the measured cos phi

and that will be reflected in an updated PF value being stated on the display. If, when the step brings in (or drops out)capacitance, there continues to be a deviation of the measured power factor compared with the target PF, a dot at + signwill flash in the case of PF is below target or dot at - sign will flash in case of PF is above the target. As the process of

adding and subtracting capacitance through this process continues, the controller compares the capacitive value and effect

of each step that is then placed in non-volatile memory. This is used to choose the most effective step or combination ofsteps to correct future PF compensation needs.

13 Due to the learning function described in the last paragraph, with the BLR-CX it is not necessary to preset any C/k

value (threshold level when to start to switch a step in or out) as each step size will be sensed automatically. The

controller does not follow a fixed switching program in the automatic mode. It will select a suitable capacitor(s), ifrecorded already, in order to achieve the target. During the daily operational routine, all capacitor effectiveness will be

stored with regard to size in numbers proportional to the capacitance (see position 8 of multifunction switch). There is no

indication in kVar as the CT ratio is unknown (except for units with option M). Where the compensation system uses

equally sized capacitors, the BLR-CX distributes switching operations equally to capacitors as much as possible. Forspecial applications there is a fixed switching program available in the ratio 1:1:1:1 (see switch position F).

14 On specific occasions, the display may have a dot (above either the +or ) flashing steadily and the controller will notswitch any step on or off: this is due to the BLR-CX not being able to find a suitable step size to compensate for the

deviation between the measured PF and the target PF. Under conditions where the measured PF is identical with the target

PF, only this PF value will be shown on the display.

15 If you are commissioning the controller but do not have an existing load, a preliminary check of the capacitor bank maybe made in manual mode (multifunction switch in position 4). Use push button +for switching on capacitors and to

disconnect. Ensure that the measurement voltage is > 50 V if you use this switch position. In this mode there is no

automatic sensing of step sizes provided this is for manual operation only. When you return back to switch position 3,the BLR-CX must disconnect all steps automatically and wait the lock time before it returns to automatic operation.

Once all required values are confirmed and / or changed, set the multifunction switch (H3) to position 3

(AUTOMATIC) and replace the front cover plate to prevent unauthorized changes of controllers settings,

remove power from the unit only after you have placed switch in position 3 in order to save your settings.

Alarm Functions

Alarms are visually shown on the display as well as by a contact changeover on the alarm relay. The relay is set for fail

safe operation; this means that when the BLX-CX is operating and everything is normal, the relay is energized and

contacts M MO are open, and M MS are closed. When an alarm is present M MO closes and M MS opens.

1 Power Factor Alarm - display shows ALand alarm contact M MO closes, M MS opens.If the predetermined power factor is not obtained due to insufficient capacitance, an alarm signal is triggered after an

elapse of 75 x the selected step switching time, this is valid for both directions - lead and lag. If the set PF target issurpassed due to overcompensation (welded contacts) after an elapse of 75 x the selected step switching time, the alarm

will be triggered and AL displayed.

Alarm reset (if required) is performed according to the description under Set Up switch position 9 (note if auto reset isselected under this switch position, reset is not required).

2 The alarm will also be triggered if the BLR-CX controller has detected failed step(s). ALxxwill be displayedalternating with other functions (cos phi) every 5 seconds. Alarm contact M MO closes, M MS opens.

Alarm reset (if required) is performed according to the description under Set Up switch position 6 (note if auto reset is

selected under this switch position, reset is not required)

3 If the supply voltage fails, there is no indication in display due to lack of power but contact at terminalsM MO will close and M MS will open providing a remote alarm contact for signalling purposes.

Data Transmission

Software WINBSTOis a simple data extraction program that provides basic information regarding power factor, operation

cycles, any triggered alarm. The data is time stamped and dated on a PC for purposes of analysis (the time / date are the PCs valuesas the BLR-CX does not have an internal time / date system). Each switching operation of the controller is accompanied with 2 sets

of information via the TTL-interface (14-position connector on the rear of controller), one before and one after switching procedure.This allows a review of the compensation effect of each step of the PF correction system. An interface cable with integrated

converter (TTL to RS232) for transmitting the data to the PC is required. Contact Illimite for details. Additional software may beavailable for special applications if you have special requirements, please contact us through our web site at www.illimite.com orwww.beluk.com and we will be pleased to assist you

It is possible to store data with an external data logger model number DS 21, 22 or 23 at the BLR-CX location within a defined

period of time. After the information is recorded, the data logger may be removed to send the information to a PC using a text

program. Contact Illimite for details.

Optional Features

Option L Fan Control & 2nd

PF Target

1 Fan ControlThe L option includes a rear mounted sensor that is used to detect a rise in the overall cabinet temperature. When

the sensor detects a temperature level above one of the four preset values, a fan control relay contact is activated atterminals LF / LF1. The fan control relay operates in the following manner:

The temperature is continuously monitored in 8 minute time windows. If the temperature exceeds the preset value

for approximately 24 seconds within the 8 minute window, the contact closes and stays closed until the sensordetects that the temperature has dropped below the preset value in a subsequent 8 minute time window. This could be

the next time window if the cabinet cooled down rapidly or it could be after several 8 minute windows have elapsed

if it takes a long time to remove the excess heat. Reset (contacts open) is achieved either automatically if the BLR-

CX has been set in the A-1 mode (see multifunction switch position 9 in the Set Up section) or manually if the reset

mode is set to A-2. For manual reset method, see the switch position 9 for details.The fan control contacts are rated at 250v / 5A max. While the fan control relay is active, the display will flash HAalternating with the normally displayed data. If both a power factor alarm and a temperature alarm happen

simultaneously, the display will indicate AH and both alarm relays will be triggered.

Preset temperature levels are 30C,35C, 40C and 45C; these correspond to 86F, 95F, 104F and 113Frespectively. To set the desired threshold temperature, remove front nameplate and program dip switches as shown

below:

Temperature 30 35 40 45

DIP S1 OFF ON OFF ON

DIP S2 OFF OFF ON ON

2 2ndPower Factor Target (High / Low Tariff)As described in the Set Up section, multifunction switch position A, there is a second power factor target in the

range from (inductive) 0.70 lag to 1.00 to (capacitive) 0.90 lead. The 2ndPF target is set in exactly the same manner

as the primary target except you are using switch position A.To switch the BLR-CX series controller with the L option from the primary PF target to the 2ndPF target, a control

voltage from 150 vac to 240 vac must be applied to terminals NT and NT1. This is usually supplied by a time

controlled relay or switch that defines when each of the selectable PF targets is desired. The primary PF target is

always the default if no voltage is applied.

Option M Measurement of Electrical Values

BLR-CX series controllers with the M option are supplied with a faceplate that includes two touch pads, +and-. The touchpads have a dual purpose: 1) they replace push buttons located behind the nameplate as found in the BLR-CX without Moption and 2) they provide an easy method of selecting electrical system values that you wish to display. In order to displayelectrical values, transformer ratios for current and voltage must be entered into the controller and permanently saved. The two

settings are made at multifunction switch positions D and E. Settings are saved by returning the switch to position 3 for Auto

operation.

The instructions for these settings are repeated below:

D Selection of CT (current transformer) RatioTo set this parameter for the BLR-CX-xx-M or BLR-CX-xx-L-M, divide the primary value of the CT ratio by the

secondary (i.e. a 400 to 5 CT would be 400/5 = 80) and set this value (your equivalent of the 80) using the +and

buttons or touch pads.Holding the button down for greater than 2 seconds advances the value rapidly. Maximum value

that can be programmed is 4000. The factory default is 100.

E Selection of PT (potential or voltage transformer) Ratio

To set this parameter for the BLR-CX-xx-M or BLR-CX-xx-L-M, divide the primary value of the PT ratio by thesecondary (i.e. a 12000 to 120 PT would be 12000/120 = 100) and set this value (your equivalent of the 100) using the

+and buttons or touch pads.Holding the button down for greater than 2 seconds advances the value rapidly. Maximum

value that can be programmed is 350. The factory default is 1.

Please note:when you are changing settings, the selected values will only be stored in the controller if the multifunction

switch is placed back into position 3 again after the changes or changes are made and before power is removed!

After the transformer ratios have been set, it will be possible to use the +and touch padsto scroll from the default display of power factor to other electrical system values as

shown.

As the transformer ratios have been set, the BLR-CX series with the M option is able to

display values correctly including an automatic change from (for example) a reading of

9999kW to 10.0MW as the value increases.

Values are updated every three seconds.
