When the return valve is opened, a microswitch activates
and supplies 24V to the pump relay and solenoids.
When the return valve is closed, it de-energizes the 24V to
the pump relay and solenoids releasing the vacuum.
When the return valve is open, the 24V circuit is closed and
it activates the pump relay and drain solenoid.
When the return valve is open, the 24V circuit is closed and
it activates the pump relay and drain solenoid.
The drain valves and oil return valves are closed. When the
oil waste discharge valve is opened, the 24V circuit is
closed, it activates the pump relay and drain solenoid.
The interlock switch is in series with the high-limit. It is
actuated when the drain valve opens, which opens the latch
circuit which drops out the 12V circuit on the interface
board. This removes power from the latching contactor
which opens and de-energizes the heating elements.
