PSL 5.0 Pump Station Level Controller
Alternate
Up to six pumps/relays can be set to alternate when in pump
mode. Following the end of a pump cycle pumps will swap
ON and OFF relay settings.
Note: Alternating pumps must have different On setpoints to
alternate correctly, otherwise alternating pumps will turn On at
the same time.
Force Alt
Set time for forced alternation. PSL will automatically trigger
pump alternation if time expires over a longer pump cycle.
On Delay
Set On Delay to invoke a delay between simultaneous changes
to pump states.
