Error Display Mode

The control enters Error Display Mode to display thermistor errors. The heater is turned off, the IN USE LED flashes to indicate the error (refer to paragraphs below), and the timer will continue to count down time. The control remains in Error Display Mode until the control senses the thermistor has returned to an acceptable heating range, the cycle ends or machine is powered down.

Open Thermistor

If the control senses a temperature less than 0°F when the heat has been on for at least three minutes it will set an open thermistor error. The control will flash the IN USE LED twice separated by a one and a half second pause. This sequence is repeated as long as the Open Thermistor error is sensed.

Shorted Thermistor

If the control senses a temperature greater than 210 ± 4°F during an active cycle it will set a Shorted Thermistor error. The control will flash the IN USE LED three times separated by a one and a half second pause. This sequence is repeated as long as the Shorted Thermistor error is sensed.

Setting Dry Time Dipswitches

To change the dry time on the dryer, combinations of dipswitches can be set on the control. Refer to Figure 25.

There are eight dipswitches on the dryer control. The first six switches are used to program the amount of additional heat time given for each coin pulse. The additional drying time is added to the factory default minimum heat time of one minute. A value of 1 to 63 minutes of additional drying time is available for each coin slide pulse.

Models Through Serial No. 0908

The last two switches are used to program the amount of additional cool down time. The additional cool down time is added to the factory default minimum cool down time of 3 minutes. A value of 1 to 3 additional minutes is available.

Models Starting Serial No. 0909

The seventh switch is used to program the amount of additional cool down time. The additional cool down time is added to the factory default minimum cool down time of 3 minutes. A value of 3 additional minutes is available.

The eighth switch is used for the cycle reset. If the switch is OFF (default), the control will save the time left on a cycle in case of a power failure. If the switch is ON, the control will clear the cycle and return to Ready Mode if there is a power failure.

All Models

The control is shipped from the factory programmed with 1 minute of minimum heat time, preset with 41 additional minutes of drying time (dipswitches 1, 4 and 6 in ON position) and 3 minutes of minimum cool down time for a total time of 45 minutes for a coin pulse. Refer to Table 6 for dipswitch settings.

The control reads the dipswitch settings at power-up. The control must be powered down to change the dipswitch settings.

To change the heat or cool down time for a coin pulse, the desired dry time dipswitches must be set to ON position. All other dipswitches must be in OFF position.

NOTE: The control must be powered down for 10 seconds before the dipswitch can be changed.

Resetting Cycle Time to Zero

To remove any cycle time that may have accumulated on the control during setup, the cycle time on the control can be reset to zero.

To reset the time, unplug the dryer and set dipswitch 8 to ON position. Restore power to the dryer for 10 seconds and once again unplug dryer. Set dipswitch 8 to OFF position and restore power to the dryer.
