Pump “Advanced” Parameters
The following parameters are used to set the “Advanced” Pump features.

below their normal “OFF” point, to discharge any sediment that may have
settled at the bottom of the vessel.
P349 Prime Level
Sets the required level to ensure pumps are fully primed after a pump run
on has occurred. Following a pump run on, any pump, whose “ON” point is
below the Prime Level will be held “OFF” until the Prime Level has been
exceeded.
P350 Run Interval
Set required time period, in hours, at which pump run on should occur.
P351 Run Duration
This parameter sets the length of time, in seconds, that pumps will run on
for, it should be noted that only one run on is allowed per Run Interval.

switching of pumps, in the following instances, (P352) Power surge (mains
or hydraulic) that is generated when multiple pumps are started
simultaneously, (P353) Power resumption following a power failure.
P352 Start Delay
Set the required time period, in seconds, that should elapse between pumps
starting. Default = 10 seconds.
