The Sporlan TCB has been developed to allow the control of most Sporlanelectric valves with the use of a generic PID or similar controller, or withthe addition of the Sporlan sensor, to perform as a stand alone temperaturecontroller. In addition to the 0 to 10 volt DC or 4 to 20 milliamps signalusual from PID controllers, the TCB can be configured to modulate avalve in response to a TTL (5 volt) signal, or a 24-120 volt AC pulse ofthree to thirty seconds duration.

The TCB may be ordered less potentiometer if an external signal (e.g. 4-20ma) isto be used. See ordering instructions. The board was designed for easy standoffmounting in electrical panels supplied by others, and with screw terminal wiringconnections. The unit is small (3.5” x 4.0”) and economical and requires only 24volts AC or 24 VDC at 40 VA for both board and valve power. Operating ambientand storage temperature is -10°F to 160°F.

The TCB has been designed to work with Sporlan SEI/SEH Electric ExpansionValves, CDS Electric Suction Control Valves, and SDR Electric Hot Gas BypassValves of any capacity (see note on page 2). Pin jumpers on the face of the boardwill permit changes in board control parameters to suit particular applications.Figure 1 shows the layout of the board with connection points labeled.

SET POINT POTENTIOMETERThe set point potentiometer may be removed from the board and relo-cated for ease of use or setting. When applied in this manner, threewires are required. Wires should be connected from the board to thepotentiometer in exactly the same orientation as when the poten-tiometer is installed on the board. Cable part number 952670 may beused in this application, see Table 3. The Potentiometer label is pres-sure sensitive material and may be applied to the remote location ofthe potentiometer. Please contact Sporlan Valve for assistance.

The potentiometer is only used when the TCB acts as a standalonecontroller. When using an external signal source the potentiometeris not required and may be removed. When used with the optionalsensors, temperature range is -40°F to 210°F.

CAUTION: The TCB with potentiometer cannot be used todirectly control an Electric Expansion Valve (EEV). EEVsmust be controlled by superheat sensing and the TCB can onlysupply a single temperature signal.

PIN JUMPERSPin jumpers are used in electronics as switches for parametersthat need not be changed after initial configuration. Alwaysremove power from the board before making pin jumper changes.

The jumper itself is a small plastic housing containing metalcontacts. These contacts will fit snugly over two adjoining pinsto create an electrical “closure”. In the tables and instructionsbelow, the Letters indicate the pins that are to be connected withthe pin jumpers. Care should be taken to make sure both pins arecovered by the jumper and the pins themselves are not damaged.

CONFIGURE THE BOARD1. Choose the valve - See Table 12. Choose the signal - See Table 23. Set the logic - See below

MOUNT THE BOARDUse the four corner mounting holes with plastic or metal standoffs.Care must be exercised to ensure that mounting screws or metal-lic standoffs do not contact any track or conductor path on theboard. Location chosen should be dry, protected and close to 24VAC supply and PID controller. If used, Set Point Potentiometermay be remotely mounted, e.g. through the control panel. Refer to“SET POINT POTENTIOMETER” section for instructions.

WIRE THE BOARD1. If using an external PID or PLC controller, connect the positive

lead to the first screw terminal on the board and the negativelead to the second screw terminal. CAUTION: The PLC orPID controller must be able to supply 20 milliamps at 12volts DC into a 600 ohm impedance. Other signals may notcontrol the TCB properly. If the internal temperature controlis used, these terminals will not be used.

2. Connect the valve leads to the next four screw terminals, match-ing indicated colors.

3. If TTL logic is being used to control the valve, connect thestep signal to the Square wave terminal and the direction sig-nal to the DIRECTION terminal. If TTL logic is not usedthese terminals will not be connected. Contact SPORLANVALVE for more information.

4. Connect a 24 VAC, 40 VA transformer to these terminals.CAUTION: The transformer may not be used for any otherdevice. The isolated secondary of this transformer is not polar-ized and may be connected to either screw terminal.

5. Connect the PUMPDOWN signal, if used. The board will closethe valve whenever a closure or dry contact across these terminalsis present. When the signal is removed or “opened” the valve willresume normal operation. No voltage should be supplied to theseterminals. If pumpdown is not required these terminals may notbe used.

The TCB pumpdown can be configured to open the valve fullywhenever a contact is made across the “pumpdown” terminals.To invoke this function, the supplied pin jumpers on P5 (OpenValve) and P6 (Close Valve) must be placed across both pins ofeach jumper.

6. Connect the temperature sensor to the two terminals. The leadsare not polarized but the sensor must be Sporlan supplied tooperate properly.

7. Two blank terminals are included for high voltage isolation.These are the second and fourth terminals up from the bottomof the board. No connections are to be made to these terminals.No screws are present in the terminals.

SET THE LOGICPlacing a jumper on either P8 or P9 will set the logic or directionof “close” in relation to the temperature sensor, or the externallygenerated signal. The “APPLICATION” section shows the jumpersettings for hot gas bypass valve or evaporator control valve appli-cations. Selection of “OPEN ON RISE” or “CLOSE ON RISE” isbased on sensor location, application, and controller logic. If thevalve operates opposite from the intended manner, move thejumper from P8 to P9 or from P9 to P8. Sporlan will be glad toprovide assistance in this selection.

SET THE BOARDWhen used as an interface board, setting adjustments are madethrough the controller used. When used as a standalone controller,setpoint is set with the potentiometer dial and test points. The diallabel will provide coarse adjustments, a millivolt voltmeter con-nected access Test Points 1 and 2 will provide a direct temperaturesetpoint readout.
