Solid-state Water Level Control and Alarm Circuit Option
The number of probes depends on the number of optional circuits being
furnished. Each water level event requires one card. The card includes an on-
board relay with (1) form “C” dry contact. Contacts are wired to a user terminal
strip for connection to remote devices such as makeup solenoids and alarms.
