Relays
Relay outputs 1 to 4 are normally On Point/Off Point relays which may be used to start/stop pumps or open/close valves at
different levels. They normally energise at one level and de-energise at a different level.
Alternatively, they may be programmed as out-of-limits alarms such that they are energised between defined points and will de-
energise outside the defined limits. They may also be programmed to perform a variety of auto-sequences and auxiliary
functions, such as pump-down operations, pump rotations to equalise wear, and desludge/cleaning.
Relay output 5 is normally a fail safe fault relay but may be re-allocated to another duty.
Relays can be set-up easily using the Relay Wizard, accessible by navigating to the RELAYS menu screen.
