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 34.
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 5 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.
Models Starting Serial No. 0909
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.
