1.0 GENERAL INFORMATION

1.1 Introduction

The DSL Model 6629 Charger, illustrated in Figure 1, is a fully automatic advanced microprocessor-controlled fast charger for DIGITAIR nickel-cadmium batteries. Each unit can accommodate up to 4 batteries at once.

To improve charging efficiency, the DSL 6629 Charger uses the Reverse Load charge method. Reverse Load is a pulse charge method that intersperses discharge current cycles throughout the charging process. Increased charge efficiency, cooler batteries, and reduced "memory" phenomenon are the result of this new method.

The DSL 6629 Charger assists the user with audible and visible signals to indicate the battery status. Faulty batteries are diagnosed and the cparge.cycle is terminated in time to protect the batteries and the Charger.

Nickel-cadmium batteries which have been stored in the uncharged state for an extended period of time may exhibit less than their rated capacity. This condition cannot be rectified by a single charge on the Model 6629 Charger although it will be improved over time.

It is recommended that DIGITAIR batteries that are new, or which have been stored unused for twelve (12) months or longer, be exercised by discharging to approximately 10 Volts (i.e. 1 Volt per cell) and then recharging, two or three times, in order to develop their full capacity. This can be done by discharging the batteries in the DIGITAIR Highly Visible Marker (HVM) light and then recharging on the Model 6629 Charger, or by using the DSL Model 6632 Battery Analyzer.

The DSL 6629 Charger is equipped with four "stations". Each station accepts one battery and works independently of the others. Charging defective batteries will not harm the unit. Overloading of the system is virtually impossible.

1.2 Functional Description

To install the Charger, connect the power cord to line voltage and turn the power on. A short tone signal is heard and all lamps come on momentarily. With no battery in place, all CHARGING and READY lamps will then remain off.

a battery, a comes on. The

beep is heard and the red battery is now on fast

When fully charged, the unit switches to trickle charge and the green READY lamp comes on. The battery may remain on trickle charge for an extended period of time without causing damage.

NOTE: The Charger may be turned·off and on with or without batteries connected. The unit will reset with a short tone signal and then connect each of the batteries sequentially. Batteries that were READY before the power was disconnected will fast charge again for a short time.

1.3 Charge Time . .

The charge time is controlled by the charge rate setting and the choice of components. All DSL Model 6629 Chargers are set to a charge rate of 0.33, at which rate the charge time for a fully discharged battery is approximately 5 hours; the charge time for a partially discharged battery is typically about 4 hours.

If observed charge times are shorter than 5 hours, this is either because the battery was partially charged beforehand or because its capacity is low. If observed charge times are longer, this is either because the battery has a capacity which exceeds the nominal 100% rating or because the line voltage is low. Batteries may be diagnosed with the DSL Model 6632 Battery Analyzer.

1.4 Termination of Fast Charge

The DSL 6629 Charger uses several methods of terminating the fast charge. How and when this occurs is governed by the battery condition. The methods are:

a) Termination of fast charge through incorrect battery voltage

If a battery is unable to reach the Window Voltage (see Note below) in the allotted time, the fast charge is inhibited by one of the conditions: "Short", "Fail 1 11 , "Fail 2 11 , or "Fail 3 11 • Termination also occurs if, due to a "soft cell", the charging battery exceeds the Window Voltage; this condition is called "Dry Cell".

Note: Window Voltage is the battery voltage range that must be reached in a given time to successfully complete the Charge cycle.



b) Full charge detection through Negative Slope

Most batteries respond to the Negative Slope Detector for termination. In the carefully selected Window Voltage, the computer monitors the-voltage pattern of the charging battery. Upon approaching full charge, the battery voltage rises sharply, peaks, and starts to fall off. This decrease in voltage (i.e., the Negative Slope) is detected, a triple beep is heard and the green READY lamp comes on.

c) Fast charge inhibit through Peak Timeout Timer

on certain batteries, no sufficient decrease in voltage is detected upon full charge. When this occurs, the Peak Timeout Timer will terminate the fast charge instead.

Typical reasons for failing to produce the n~gative slope are:

- Battery has poorly matched cells; leaky cell(s); - Battery has

- Battery is new and is being charged for the first time; or

- Battery had time.

been in discharged condition for a long

Similar to the Negative Timeout Timer produces a READY lamp comes on.

Slope Detector, the Peak triple beep and the green

NOTE: The careful observer may notice different pitches of the triple beep tones. If the fullcharge detection occurs through the Negative Slope Detector, a high pitched triple beep is heard (2400 Hz); if it is caused by the Peak Timeout Timer, a low pitched triple beep occurs (674 Hz).

d) Fast charge disabled through "Dry Cell" condition

A battery normally fails due to low capacity before it dries out. However, if a Dry Cell condition exists, the Charger will disable the fast charge. The Dry Cell condition may show up after only a few minutes or after hours of charging.



1.5 Temperature Sensors

Temperature sensors are installed at each battery station. Should the battery case temperature exceed 44°C (111°F), the sensor terminates al'l charge current. A hot battery is indicated by rapid flashing of the red CHARGING lamp. After the battery has cooled down to 40°C (104°F), trickle charge commences. The CHARGING lamp alternates with the READY lamp. To reset, remove and replace the battery. ·

If the temperature is less than 15°C (59°F), trickle charge is applied and the CHARGING lamp flashes once per second. After the temperature rises above 15°C (59°F), the battery is fast charged and the cycle proceeds as usual.

It should be noted that there is no beep signal when inserting a battery that is out of temperature range.

Before opening the box, check for, and record, any damage to the outside of the box. Remove Charger from the box; check for, and record, any damages.

If the unit is damaged, the shipper should be notified immediately. All packing material and contents must be kept available for inspection by the shipper's claim agent. Failure to do this may result in denial of liability for damage by the shipper.

2.2 General Test

Follow the power up procedure given in Section 3.2 below.

2.3 Operationa1 Test

Charge a battery as described in Section 3.3 below.



3.0 OPERATING INSTRUCTIONS

3.1 Introduction

The Charger has four battery positions or "stations". Each position has locating pins to ensure correct placement of the battery and to prevent reverse polarity connection. Each battery station functions independently. Charging of a battery is automatic and starts when the battery is placed on the Charger. Full charge is detected automatically, after which the battery receives a trickle charge to keep it at full capacity. Audible and visible signals indicate battery status. Faulty batteries are diagnosed and charging stopped in time to protect the battery and the Charger.

3.2 starting the Unit

on power up, momentarily. green lamps remains on.

3.3 Charging

a single tone is heard and all lamps come on With no batteries in place, the red and remain off and the yellow POWER ON lamp

When a battery is placed in charging position, a beep tone is heard indicating proper contact. The red CHARGING lamp comes on showing that the battery is on fast charge.

Typical charge time for a battery in good condition is approximately 5 hours. This will be less if the battery capacity is low or if the battery was partially charged initially. If the charge time is longer than 5 hours, either the line voltage is low or the battery capacity exceeds the nominal rating.

When a battery is fully charged, a triple beep tone is heard, the green READY lamp comes on, the red CHARGING lamp goes off, and the Charger switches to trickle charge.

Batteries may be left on trickle charge for extended periods without harming the batteries.

NOTE: The Charger may be turned off and on with or without batteries connected. The Charger will reset with the power on tone and then connect each battery sequentially. Batteries that were READY before the power was disconnected will charge again for a short period of time.



3.4 Battery Temperature Sensing

The DSL 6629 Charger is equipped with a temperature sensor at each battery station •

. Should the battery case temperature exceed 44°C (lll°F), the red CHARGING lamp will flash. After the battery has cooled down, trickle charge will commence indicated by alternate flashing of the red and green lamps. To reset, remove battery. ·

If the temperature sensor measures less than 15°C (59°F), only trickle charge is applied, indicated by a slow flashing of the red CHARGING lamp. When the temperature rises to 15°C (59°F), the normal fast charge cycle will commence.

4.1 Introduction

Full charge detection and analysis of battery deficiencies are functions of the software. The status of each battery is indicated with the CHARGING and READY lamps located near each battery station. For quick reference, see the front label of the Charger or turn to the Indicator tables given in Section 6 below.·

When connecting a shorted battery, charging is terminated after six (6) seconds. The READY lamp flashes and a continuous sound is heard. Remove and discard the battery.

4.3 FAIL 1 (Partial Short)

This battery is basically shorted, but may have a few functioning cells remaining. The charge time is limited to three (3) minutes. The READY lamp flashes at a rate of once per second to indicate the condition. The battery is not usable.

4.4 FAIL 2 (Low Battery Voltage)

The low voltage battery has a number of faulty cells. The charge is terminated after thirty (30) minutes. The READY lamp flashes at a rate of twice per second. Discard the battery.



4.5 FAIL 3 {Depressed Battery Voltage)

Due to one or more faulty cells, the battery is unable to reach the Window Voltage. The charge is terminated after three (3) hours. The READY lamp· flashes four (4) times per second to inform the user of this deficiency.

A "Dry Cell" condition occurs when one or more cells lack electrolyte. This condition makes the battery "soft" in which state it can no longer clamp the terminal voltage down when charging. A four-flash-per-second READY lamp and continuous tone indicate this condition. Charging is terminated. The battery can no longer be used and should be discarded.

If a cold battery is fast charged, an apparent "Dry Cell 11

condition may also occur. Allow the battery to warm up for several hours before charging.

4.7 Faulty Battery Connection

A faulty battery connection raises the terminal voltage when in Charge mode. This condition switches the Charger between Reset (no battery) and Charge (battery inserted). Random flashing of the CHARGING lamp occurs and beep tones are heard.

To correct this problem, clean all connections on both the Charger and the battery. If no improvement is apparent, the battery is probably faulty and should be discarded.

4.8 Open Battery

The battery cannot accept a charge current, and the Charger remains on Reset. No lamps or tone signals are activated. Check and clean all contacts.

4.9 Venting Battery

Older batteries often develop a problem whereby, due to aging, the cells become increasingly mismatched. This is aggravated by the fact that the weak cells reach full charge before the good ones do, thus causing elevated temperature and excessive pressure in these cells. A further deterioration of the weak cells is therefore inevitable.



When a cell reaches excessive pressure, venting occurs. A popping or hissing sound may be heard. There is no danger to battery or equipment; however, repeated venting can lead to the "Dry-Cell" condition described above.



5.0 THEORY OF OPERATION

5.1 General

The circuitry of the DSL 6629 Charger is divided into four sections: Auxiliary Circuit, Control Circuit, Charging Drivers, and Display Indicators (the LED indicator lamps). A block diagram and schematic of the complete Charger are provided in Section~ below.

5.2 Auxiliary Circuit

The Auxiliary circuit consists of: Power Supply, Overload Detector, Reset Circuit, Sounder driver, POWER ON lamp driver, Clock Oscillator, and Code Selector.

(a) Power Supply

The power supply consists of rectifiers CRl and CR2, and a three-terminal regulator Ul which has internal protection for both overcurrent and excessive temperature. output voltage is set to the required 5.12 voe using potentiometer Rl.

(b) overload Detector

The overload detector senses the transformer temperature via a thermistor and shuts the Charger down should the transformer exceed a certain temperature.

Since the charge rate on all DSL Model 6629 Chargers is fixed, the current demand on Tl is fixed. As such, the thermistor is not required and is therefore not installed on any DSL Model 6629 Charger. The following description is included for completeness only.

The detector circuit consists of capacitor and comparator U2B. If a thermistor (RTl) were installed, it would be connected to P2. On sensing high temperature, RTl would allow Cl to charge, switching comparator U2B output Low then High.

The rising positive edge applied to processor U3 (INT 1 input) would place the processor in "sleep mode", shutting down the Charger.



(c) Reset Circuit

The Reset circuit provides a Power On reset to the microprocessor when power is first applied. C4 charging at U2A pin 5, causes comparator U2A output pin 2 to switch Low for a few milliseconds and then to switch High. The Low applied to U3 pin 23 resets the microprocessor U3.

A Watchdog timer circuit consisting of U2C and U2D monitors microprocessor U3 for continuous activity and enables the Reset circuit should normal operations cease. Pulses superimposed on the POWER ON lamp output line (U3 pin 24) are monitored by pulse shaper U2D.

Should pulse activity second, the output of output, normally High, fed to comparator microprocessor Reset.

cease for more U2D will go High. now switches Low.

U2A via C7

then about one Comparator U2C This signal is initi&ting a

The Watchdog timer circuit also triggers a reset if the input AC power rises slowly. (e.g., after a brown-out).

(d) Code Selector

The Code Selector is unused in the DSL 6629 Charger. The charge rate was at one time set by jumpers placed on the Code Selector header, but now the rate is fixed at 0.33 in firmware. The Code Selector header should have no jumpers placed on it.

5.3 Control Circuit

Refer to both the block diagram and the schematic for the following descriptions; both drawings are provided in Section 8 below.

The following items processor U3, EPROM Addressable latch U6.

comprise the Control Circuit: Micro(or PROM) U4, latch U5, and 8-bit

EPROM U4 contains the program for the Charger's microprocessor. The microprocessor U3 uses a multiplexed address/data bus DB 0-7 to obtain its instructions from U4.

To read an instruction from the EPROM, the microprocessor first outputs 13 address bits. The lower order address bits 0-7 are latched in D latch U5. The higher order bits remain on. the direct address bus throughout the read cycle. The EPROM output is then enabled allowing the reading of data, by the microprocessor, on DB lines Oto 7.



Latch U6 acts as an addressable LED driver for all four stations.

The Control Circuit charging stations via U3 provides Control drivers as follows:

Analog, o to 5.12V, indicates battery temperature (see Sectin 5.6 below).

> Reverse Polarity: Normally high, low when battery reverse polarized.

5.4 Charging Drivers

The function of the Charging Drivers is to provide Fast Charge, Trickle Charge, and Reverse Load cycling.

The DSL 6629 Charger contains four Charging Drivers, one for each battery station. The charge current and hence charge time is determined by the choice of components and by the control signals from microprocessor U3.

As all drivers are identical, only one circuit will be described. Refer to the block diagram and the schematic for the following descriptions.



(a) Driver Component Designation

All components in the Charging Drivers are identified by a three-digit number. The first digit designates the Charging Driver (Driver 1, 2, 3 or 4). The second and third digits position the components, and are repeated on each Charging Driver as their allocations are the same for all positions. In the following description, the first digit is replaced by an "x", In this way, the description is of Charging'Driver "x", where "x" may be 1, 2, 3, or 4.

(b) Input/Output

Each Charging Driver responds to the three control signals described in Section 5.3(a) above and provides the supervisory signals described in 5.3(b).

(c) Fast Charge

Voltage is applied on the Fast Charge line, via Rx03 to pin 1 of UxOl. Pin 2 of UxOl is connected to the unregulated DC line from CR3; this has a high 60 cycle ripple content.

The output of UxOl at pin 1 applies a ground potential at a rate of 60 times per second, synchronous with the line voltage. Capacitor Cx02, also connected to pin 1 of UxOl, acts as an integrator to produce a sawtooth waveform.

This sawtooth wave is compared with the reference voltage on pin 5 of UxOl. The resulting output pulse on pin 2 of UxOl coincides with the positive half of the AC and turns on driver QxOl-1, allowing charge current to flow through the series pass transistor Qx02.

(d) Trickle Charge

Unlike fast charge, trickle charge uses only a fraction of the positive AC pulse. A different timing ratio of Rx04 and Cx02 produces a lower saw-tooth voltage. The pulse width, and hence the trickle charge current, are determined by the value of Rx04. (A higher resistance will produce less current). The trickle charge current is set to 235 mA nominal on the 6629 Charger; this value is approximate and varies both with battery terminal voltage and with line voltage.



(e) Reverse Load

A special feature of the DSL 6629 Charger is Reverse Load cycling by which a brief discharge is applied between each charge pulse. This feature stimulates the battery and reduces the "memory" phenomenon associated with nickel-cadmium batteries.

On both fast charge and trickle charge, Rx12 and Rx13 produce a reference voltage (pin 10 of UxOl) that compares with the AC ripple which is superimposed on DC (pin 11 of UxOl). The resulting output (pin 13) is a zero going pulse, turning Qx03 on during that period.

The Reverse Load is active between charge pulses. The average Reverse Load discharge is approximately 10% of the battery's Ampere-hour (Ah) rating.

(f) Reverse Polarity Detector

If a negative voltage potential is read on the voltage divider of Rxl8 and Rxl9, pin 14 of UxOl switches from High to Low, informing the microprocessor of a reverse polarity condition. CRx03 acts as buffer. If a battery is connected backwards, the charge current is immediately stopped.

(g) Temperature Sensor

The voltage reading produced on the divider consisting of Rx25 and the thermistor is fed to the A/D converter of the microprocessor. The thermistor (NTC) has a nominal resistance of lOOK ohms at 25°C (77°F).

If the thermistor becomes disconnected, the software will simply ignore the temperature sensing.

The DSL 6629 Charger is equipped with an internal Interface Jack, P4, a 2x5 header on the main PCB. It provides access to the serial lines to the microprocessor and has the analog reference voltages (V-sense) of all four batteries.



NOTES: 0 Since no function is presently implemented for the serial lines, the Interface Jack P4 is useful only for monitoring the sensed battery voltages.

0 V-sense is the battery voltage dropped by Rx18 and Rx19 and dropped through diode CRx01.

o The v-sense outpu~s cannot be loaded; a high-impedance voltmeter may be used.

(1) The high pitched (2400 Hz) triple beep is used when the full charge is terminated by the Negative Slope Detector (normal battery). On batteries with poorly matched cells, the Peak Timeout Timer terminates the fast charge, indicated by a low pitched triple beep (674 Hz).

(2) Above indicated time is for charge rate of 0.33 (i.e., as supplied by DSL).

(3) The "DRY CELL" condition is activated when battery voltage rises too high while on Charge.

(4) "FAULTY BATTERY CONNECTION" occurs when the terminal voltage cannot be sufficiently clamped.

(5) As explained in Section 5.2(b) above, this feature is not implemented on the Model 6629 Charger.



CAUTION: Troubleshooting and repairing of this instrument must only be performed by a qualified technician. Disconnect power before opening instrument.

6.5 Failures of the Charger

SYMPTOM

1. No reset tone, no LED when power turned on

2. No reset tone, some LED(s) on

3. CHARGING LED flashing@ 1Hz and continuous tone (same as short but with no battery)

POSSIBLE CAUSE

• No AC voltage . No control vol

tage

• No clock • Microprocessor

not reset . Faulty reset

circuit

• Dead driver • Faulty V-sense

FAULT DiiGNOSTIC

a. Check for open breaker or control fuse in power supply.

b. Check for 5.12V on pin 7 of Interface Jack or on any IC.

c. If no control voltage, cpeck fpr heating up of Ul (LM317 on heatsink).

a. Check clock activity (11.0592 MHz). NOTE: Oscillator is integrated in U3 .

b. Reactivate power switch. Check for low-to-high voltage on pin 2 of U2.

c. Manually activate reset by momentarily shorting pin 2 of U2 to ground. NOTE: If microprocessor resets with step 2a, problem is in reset circuit.

a. Determine which driver is faulty and find V-sense pin on Interface Jack. NOTE: V-sense for Station 1 is pin 5 of Interface Jack. V-sense for Station 2 is pin 3 of Interface Jack. v-sense for Station 3 is pin 6 of Interface Jack. V-sense for Station 4 is pin 4 of Interface Jack.



SYMPTOM

4. CHARGING LED on, no continuous tone, (same as fast charge but with no battery)

POSSIBLE CAUSE

• Low line voltage

. Faulty Driver

. Faulty Rev.Load

. Faulty V-sense

FAULT DIAGNOSTIC

b. Check for short in battery leads or receptacle.

c. Check V-sense circuit. d. If V-sense is low,

raise V by applying +V .(5.12 V) and observe.

e. If no charge current, initiate charge by turning on Qx02 (momentarily connect lK resistor from base to ground and observe charge current).

f. Examine pulse activity of Charge Regulator on pin 1 of UxOl. If dead:

g. Check voltage on input side of Rx03 and Rx04 (leading to U3). NOTE: Fast charge: Rx03 high. Trickle charge: Rx04 high. No battery: Rx03 & Rx04 low (no charge). Short: Rx03 & Rx04 low (no charge). Hot battery: Rx03 & Rx04 low (no charge). Cold battery: Rx04 high (trickle charge) •

a. Check line voltage, must be 100 VAC or more.

b. Examine Charge Driver and Reverse Load Driver for leaky component, ie, QxOl, Qx03, CRx03.

c. Check V-sense circuit.



SYMPTOM

5. CHARGING LED flashing, sounder beeping, (switching be-tween reset and charge with no battery)

6. CHARGING LED off, sounder silent with battery in

7. Good battery fails:

POSSIBLE CAUSE

• Faulty battery reset

. Faulty battery leads

. Faulty V-sense

. Charge current too low

. No charge current

. Wrong charge rate setting (too high)

FAULT DIAGNOSTIC

a. Examine Rx21 (pull-up resistor).

b. See also 4 a, b, & c. NOTE: With no battery in, all V-sense lines

· should be 5. 24V (reset mode). Leakage in v-sense circuit will lower V-sense voltage, stimulating a battery and hence initiating charge. V-sense rises to reset mode, the cnarge.is turned.off, and the cycle is repeated.

a. Check for open battery terminals, cables and plug •

b. Examine drop in V-sense when battery inserted (clamping action); if none:

c. Check for fault in v-sense line (short to +V).

d. Simulate v-sense drop by placing lOOK from Rxll to ground and observe.

a. Analyze whether problem is common to all Stations. If yes: check reference voltage on pin 5 of UxlOl; it should read 0.9V. If incorrect, examine R105, R106, C105, UlOl.



SYMPTOM

8. Battery gets hot when in charge mode (see "Note" at end of table)

POSSIBLE CAUSE

. Old battery

. Wrong charge rate setting (too low)

. Faulty microprocessor

FAULT DIAGNOSTIC

b. Check charge rate setting. On DSL 6629, setting is 0.33 (Code 0100). If problem is isolated to one station·:

c.·Examine charge current by placing ammeter in line with affected battery. on the DSL 6629, charge current should be between 0.8A and l.2A on good battery.

d. If charge current.low, examine· . Rxl O . NOTE : All parallel power resistors (set of 4) should heat up equally.

e. Examine charge pulse on battery terminal. Check for full positive wave. If only partial wave present, check pulse width in Charge Regulator.

f. Check voltage on Rx03 (input side), must read 5.12V; check CxOl and UxOl.

g. If no charge, refer also to 3 e, f, & g.

a. Old and leaky batteries heat up more towards end of charge cycle than do newer batteries. No excessive heat build up should occur with any battery.

b. If charge rate setting is too low, time-out will be delayed. NOTE: Timers are used on Short, Fail modes, and Peak Timeout Timer.

c. Observe microprocessor for proper operation.



SYMPTOM

9. Battery gets hot when in READY mode (see "Note" at end of table)

POSSIBLE CAUSE

. Trickle charge current too high

FAULT DIAGNOSTIC

a. Analyze whether problem is common to all Stations. If yes, check reference voltag~ on pin 5 of UxlOl. It should read

· 0.9V. If incorrect, examine R105, R106, C105, 0101. If problem is isolated to one Station:

b. Examine charge current by placing Ammeter in line with affected b~ttery. On DSL 6629, charge current should be between 0.2A and 0.3A on a good battery.

c. Examine charge pulse on battery terminal; should show only partial positive wave (approx. 1/3 towards end before going to zero). If charge pulse is too wide, check pulse shape in Charge Regulator.

d. Examine Reverse Load. Between charge pulses, observe brief discharge. If missing, check Reverse Load Driver/Modulator, check Qx03-1, Rx20; also check voltage on input of Rx12. Reference voltage on pin 10 of 0101 should read 3.25V when in charge mode. NOTE: Fast charge: Rx12 high (on input side). Trickle charge: Rx12 high (on input side). No battery: Rx12 low (on input side) .



SYMPTOM

10. CHARGING LED flashing@ lHz

11. CHARGING LED flashing@ 4Hz

POSSIBLE CAUSE

. Ambient too cold

. Faulty thermistor

. Thermistor hot

. Faulty thermistor

. Housing hot

FAULT DIAGNOSTIC

a. Check room temperature. If less than 15°C (59°F), fast charge is disabled.

b. Check thermistor {lOOK @ 25°C'or 77°F). NOTE:

· A temperature range of 15°C-44°C {59°F-lll°F) produces v-temp of 3.4-l.7V.

c. Disconnect thermistor and observe. v-temp should reach 5.12V. NOTE: If no thermistor is used, temperature s'ensing is ignored .

a. Check battery temperature. If thermistor reads more than 44°C {lll°F), Charger switches to "Battery Hot" mode.

b. See also 10 a, b, & c.

Note: The temperature of a good battery will increase to about 10 Celsius degrees above ambient at end of fast charge. On older batteries, a 15 Celsius degree increase is common. A nickel-cadmium cell should never exceed 55°C.
