Timer Testing
1. For testing purposes only, set each of the three (3) cycle timers to the 3 minutes range and adjust
timers to approximately 2 minutes.
2. Turn ON the dryer’s main power and dryer circuit breakers.
3. Start the dryer control circuit; turn the Mode Selector switch to AB or SA and the Electronic Moisture
Control switch (CF/AB) or the MC Selector switch (CF/SA) to OFF. Also turn the Unload switch to
AUTO, the CF/AB Fan switch to ON, the CF/AB Burner switch to AUTO; or the CF/SA Bottom Fan
switch to AUTO and the CF/SA Bottom Burner switch to AUTO.
4. Run the dryer through a complete HEATING, COOLING and UNLOAD cycle, being sure that the
cycles are completed as described in your operator’s manual.
5. MC HOLD CHECK: Restart the dryer and turn the Electronic Moisture Control switch (CF/AB) to ON
or the MC Selector switch (CF/SA) to ON. Also set the MC temp dial to its maximum set point. The
HEAT timer should complete its drying cycle, the MC hold light should come ON and heating should
continue. Decrease the MC set point until the MC hold light turns OFF. The heater should turn OFF
and the cooling cycle begins. Adjust the MC set point back up. The cooling cycle should continue.
6. UNLOAD AUGER SWITCH CHECK: Turn the Unload Auger switch to OFF. When the cooling cycle
is complete, the dryer will hold in the cooling mode until the Unload Auger switch is turned to AUTO
to begin the Unload cycle.
7. CONTINUOUS FLOW CHECK: Turn the Mode switch to Continuous Flow (CF/AB) or CF (CF/SA).
Also turn the Unload Auger switch to AUTO and observe that the unload auger and meter rolls are
operating and that the timers are not timing.
8. Reset the timers to the appropriate settings and ranges as recommended by the CYCLE TIME
CHARTS. (The times listed match those in the operator’s manual, except they are also listed with
decimal hours for convenience.)
