ELECTRICAL SYSTEM
Vacuum Switch (25):
This switch is used to toggle the state of the vacuum motor. Pressing and releasing this switch will alternately turn the vacuum motor on and off.
The indicator
(26)
provides the following status information:
Off - Vacuum output is off and there is no current flow through the contactor coil and no vacuum motor current sensed.
Green - Vacuum output is on and there is normal current flow through the contactor coil and normal vacuum motor current sensed.
Flashing yellow - Either the vacuum motor output is off and there is current flow through the coil or vacuum motor current is sensed (shorted output
driver, control error, shorted contactor, wiring error) or the vacuum motor output is on and there is no current flow through the coil or no vacuum
motor current is sensed (open circuit, open relay coil, open contactor contacts, wiring error or open output driver).
Solution Switch (23):
This switch is used to toggle the state of the solution solenoid. Pressing and releasing this switch will alternately turn the solution solenoid on and
off. The indicator
(21)
provides the following status information:
Off - Solenoid output is off and there is no current flow through the solenoid coil.
Green - Solenoid output is on and there is normal current flow through the solenoid coil.
Flashing yellow - Either the solenoid output is off and there is current flow through the coil (shorted output driver or control error) or the solenoid
output is on and there is no current flow through the coil (open circuit, open solenoid coil, or open output driver).
