4-2 System Operation Procedures
1. Turn the disconnect switch on the control panel to the ON position. Power is applied to the voltage
line fuses and line side of the control power switch.
2. Turn the control power switch to the ON position. Power is applied to the PLC and touch screen.
Push the start button on the PLC and the valve will move to the start position as follows:
a. The valve motor rotates until the cam switch makes 2 transitions.
b. If the cam switch does not make a transition within 10 seconds, a valve motor fault
alarm is generated. The alarm horn and light are activated. The valve motor, heaters,
and blower shut off. Pressing the ALARM SILENCE pushbutton will deactivate the
alarm horn and light.
Note: Cycle control power to restart the dryer.
c. The valve will normally complete one full cycle (revolution). If sequence shutdown is
not initiated (in 10 Seconds) and control power switch or disconnect are turned off:
3. The bed in process at power-down will remain in process.
4. The bed in regeneration at power-down will remain in regeneration.
5. The regeneration timing cycle will restart from the beginning.
