delay time in hours and then in minutes. The range of adjustment is 1
minute to 99 hours 59 minutes in increments of 1 minute.
The purpose of the delayed restart is to prevent the pump from restarting
once it has stopped on high pressure. As an example, if the pump system
was being used to
fi
ll a tank that had a
fl
oat valve
fi
tted to it and the valve
closed then the system pressure would rise and the E30 would shut the
pump down once the pressure reached your high-pressure cut-out point.
Ordinarily, if the
fl
oat valve leaked or opened, the pressure would fall and
the E30 would start the pump as soon as the pressure reached your set
cut-in pressure. The delayed restart function can be used to delay the
restarting of the pump. The delay may be to prevent the pump from hunting
on and off or it may be to allow time for the water level in the tank to drop
some distance before allowing the pump to restart. If you select yes to this
function and enter a suitable delay, the question that follows asks: -
AUTO START AFTER DELAY
Selecting yes to this question means the pump will only restart when
conditions are suitable, for example in mode 1 when the system pressure
is below the set cut-out pressure. In this situation, the pump would not
normally start until the pressure fell to below the set starting pressure. Auto
start after delay overrides this and instantly starts the pump. Selecting off
to this question means that after the delay period the pump will only start
under conditions it would normally start under. For example, in mode 1 it
will only start when pressure falls to below the normal set starting pressure.
AUTO RESTART IF RUN DRY
Mode 1
The E30 will identify a dry run situation as a loss of pressure. If the pump
shuts down because it has run dry, it can be set to try to restart using the
auto restart function after a settable delay. The range of the delay is 1
minute to 99 hours 59 minutes in one minute increments.
SINGLE RESTART ON A FAULT YES.
Select this option if you want the
pump to try to restart one time only.
REPEATED RESTARTS ON A FAULT YES
. Select this option if you want
the pump to repeatedly try to restart after the delay period.
BATCH CONTROLLER
Mode
1
If you choose to use auto restart as described previously, the E30’s batch
controller will not appear in the menu. To use the batch controller, you
