The start-up timer is initially set to 5 seconds by default. If you purge the E30
program the start-up timer will be reset back to its default 5 seconds.
Mode 2 Run-on Timer
The E30 includes a run-on timer that can be set from 1 second to 900 seconds
(15 minutes) 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 shut down 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. In applications where
motorised valves are opening or long runs of pipe take time to pressurise, the run-
on timers ability to tolerate system pressures that are less than the normal running
pressure is an invaluable feature.
The run-on timer is initially set to 5 seconds by default. If you purge the E30
program the run-on timer will be reset back to its default 5 seconds.
Mode 2 Low Pressure Trip
The low pressure trip point can be set to any value from zero to 2000 kPa or from
zero to 290 psi, depending on the pressure units you have chosen to use. The
low pressure trip point must be set to some value that is less than the high pressure
trip point. If you attempt to set the low pressure trip point to a pressure that is
greater than the high pressure trip point you will invoke a pressure warning from
the E30 alerting you to the problem. If the pressure falls to below the low pressure
trip point during normal operation, it is the set trip pressure that invokes the run-on
timer and ultimately shuts the system down if pressure fails to rise above its set
point by the end of the run-on period. The trip pressure will normally be set to
some value that is well below the high pressure trip point setting.
Mode 2 High Pressure Trip
The high pressure trip point can be set to any required value above the low
pressure trip point. The range of adjustment is zero to 2000 kPa or zero to 290
psi in increments of 1 kPa or 1 psi depending on the pressure units you have
chosen to use.
The high pressure trip point will ordinarily be set to some value that is well above
the low pressure trip point. If you attempt to set the high pressure trip point to a
pressure that is lower than the low pressure trip point you will invoke a pressure
warning from the E30 to check your pressure settings.
