wire

Section D for proper resistance readings.

 

Thermistor Probe

Inspect the thermistor bulb for its proper location in

 

 

its spring holder. Check for short in leads where

 

 

they enter the sensor bulb. Also check each

 

 

thermistor lead for short to ground.

 

Thermocouple Probe

Place your pyrometer thermocouple into the center

 

 

between fingers T2 and T3 in the oven. Connect

 

 

temperature meter to thermocouple at 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 reading 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 display

If strange or unusual behavior is experienced such

 

 

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 inaccurate

Perform the power supply check, the thermistor

 

erratic, or inoperative

probe check, and then perform the time/temp

 

 

simulator test. Refer to page 51 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 inaccurate

Perform all checks as in the above evaluation. If

 

erratic, or inoperative

the time check is okay, refer to the next section

 

 

optical encoder.

 

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.
