CLOSED DURING PRE-START DELAY
Relay 2 can be used to run
peripheral equipment such as mixers prior to the pump starting. Relay
2 opens when the pre-start timer times out and turns off the peripheral
device.
PRE-START DELAY TIMER
Modes
1 2 4
The pre-start delay timer delays the starting of the pump for a settable
period. It can be used to allow peripheral equipment to operate prior to
a pump starting. For example to allow a mixer to operate prior to starting
a pump. It can also be used to sequence or stage the starting of multiple
pumps in sequential or cascaded transfer pumping systems. Starting
pumps sequentially rather than all at once in such systems greatly reduces
the current draw on the power supply and ensures each pump spins up
to full speed before the following pump starts. The delay can be set from
zero to 64800 seconds (18 hours) in one second increments. The count
increments up in 60 second steps and down in 1 second steps.
START-UP TIMER
Modes
1 2 4
The E30 includes a start-up timer. The purpose of the start-up timer is to
ignore any initial lack of pressure and allow time for the system pressure to
rise above your set trip pressure before imposing any pressure limits on
the pump’s operation. The start-up timer can be adjusted from 1 second to
900 seconds in increments of 1 second. The start-up timer automatically
terminates its run as soon as a pressure higher than the set starting
pressure is detected. The start-up timer is factory set to 5 seconds. It can
be set between 1 second and 900 seconds using the
(

and (
˄
) buttons.
RUN-ON TIMER
Modes
1 2
The E30 includes a run-on timer that can be set from 1 second to 900
seconds in increments of 1 second. The purpose of the run-on timer is to
allow the E30 time to tolerate momentary dips in pressure that would
otherwise cause the shutdown of the pump. You can choose not to use the
run-on timer by setting its time to zero. If you do this then the instant the
E30 detects a pressure less than its trip pressure the pump will be shut
down.
