LEVEL INPUT
The pump receives a dry contact or open collector signal from a fluid level device to
indicate a low level in the solution tank. When a signal is received on the level inputs, the
pump will stop running and the display will flash LEVEL.
If the pump stops receiving the signal, the pump continues to run and the level flashing
indicator automatically clears.
