Thermocouple Probe

Place your pyrometer thermocouple into the center

 

 

between fingers T2 and T3 in the oven. For ovens

 

 

with Mechanical Measure D.C. millivolts at

 

 

Thermostat terminals 9 and 10 on the time/temp

 

 

display. See thermocouple chart on page 59 for

 

 

proper readings. Replace thermocouple if proper

 

 

readings not achieved. If readings are correct on

 

 

the thermocouple, replace time/temp display.

For ovens with

 

Connect temperature meter to thermocouple at

Electronic Thermostat

 

terminals 9 & 10 on back of the time/temp display.

 

 

(Be sure to maintain proper polarity on

 

 

thermocouple connections.) Compare actual oven

 

 

temperature with the readings at the time/temp

 

 

display. If the temperature readings match,

 

 

recalibrate or replace time/temp display. If the

 

 

readings do not match, replace thermocouple

 

 

probe.

Erratic time/temp

 

If strange or unusual behavior is experienced such

display

 

as a rolling of numbers, lock up at a given number,

 

 

first check for a display circuit lock up. This can be

 

 

caused by a voltage spike or surge. To eliminate

 

 

this condition remove power from the time/temp.

 

 

display by shutting off the main fan switch, or if

 

 

display stays on, (older models) circuit breaker

 

 

interruption may be required. This should eliminate

 

 

the problem. If the problem continues, jumper the

 

 

two fuses in the red wires leading from the 12.6

 

 

VAC transformer to the display. If this does not

 

 

solve the problem, it may be coming in through the

 

 

commercial power lines. Suggest that customer

 

 

contact his power company for evaluation.

Temp Display

 

Perform the power supply check, the thermistor

inaccurate erratic, or

 

probe check, and then perform the time/temp

inoperative

 

simulator test. Refer to page 72 for instructions.

 

 

Remember, when using the time/temp simulator,

 

 

remove all the leads from the back of the display

 

 

except the 3 power leads. After completion of this

 

 

test and if reinstalling back into the oven, the dip

 

 

switches must be reset for oven operation.

Time display

 

Perform all checks as in the above evaluation. If

inaccurate erratic, or

 

the time check is okay, refer to the next section

Optical Encoder

The above time/temp test should have already

 

 

been performed. Remove dust cover from the

 

 

gearmotor and inspect the coupling and encoder

 

 

disc. The coupling set screws should be tight and

 

 

not slipping on the motor shaft or the tach.

 

 

generator shaft. The encoder disc should be firmly

 

 

attached to the coupling and not warped. Check the

 

 

positioning of the optical encoder disc. The disc

 

 

should not be touching the optical encoder

 

 

assembly and the encoder assembly should be

 

 

mounted so it is squarely facing the coupling shaft.

 

 

This is to allow the infrared beams to be broken by

 

 

the encoder disc. If all this is okay, then replace the

 

 

optical encoder assembly.
