7. Troubleshooting

The TC models are very reliable if installed and operated

properly.
If, for some reason, your TC does not function properly,

first confirm that it is installed properly. See Section 2,

Installation.
If the TC malfunctions after it has been operating routinely,

refer to Table 4, Troubleshooting Chart.
This Troubleshooting Chart identifies causes and solutions

to the malfunction. For further assistance contact the

Customer Integrity Team at [email protected] or call-

ing 1-844-435-8982.

Table 4 - Troubleshooting

Condition

Probable Cause

Solution

Electrical

Display shows A.TMP-ND

No winding temperature decrease within five (5)

minutes of Fan(s) turn on

Verify proper fan operation.

Display shows A.T-R-CON

Thermocouple wired reverse polarity

Verify proper polarity of thermocouple connections.

Display shows A.T-O-CKT

Thermocouple Open Circuit

Winding temperature (s) colder than internal con-

troller temperature

Verify thermocouple is connected properly.

Replace thermocouple if broken.
If this is a typical operating condition, disable

reverse thermocouple detection

Display shows A.OVRTMP

Winding temperature(s) exceed Alarm threshold

Verify proper alarm setpoint and if correct trouble-

shoot and repair any transformer overloading, fan

failure, airflow blockage, etc.

Display shows A.AIR-ND (TC-100 only)

Discrete Input Activation

Troubleshoot reason for discrete input activation

and make any necessary repairs

Display shows A.FANWEAR (TCC-100 only)

Total fan operating time has exceeded the pro-

grammed threshold

Perform any required fan maintenance based on

this operating time and Reset the FANWEAR hours

via the front panel Reset menu

Display shows A.FAN ONT (TC-100 only)

Fan has been operating continuously for at least

24 hours

Troubleshoot and repair any potential transformer

overloading, fan failure, airflow blockage, etc.
Note: This may be a normal operating condition

during periods of high ambient temperature and

heavy transformer loading

Display shows A.FRAM or A.EEPROM or A.ISO-OR

Internal Controller Failure

Return controller for repair.

Fan(s) not turning on

Improper programming

Open Fuse
Bad wiring/fan

Verify proper programming of fan mode and set-

points
Determine/repair cause of fuse opening. Replace

fuse
Rewire/replace fan, as required
