fi
rst have set auto restart to off. The batch controller and auto restart
functions con
fl
ict so the E30’s menu prevents you from selecting both
functions. The batch running time can be set from 1 minute to 99 hours 59
minutes in one minute increments.
The batch controller allows you to have the pump run for a set period and
to then automatically shut down. An example of its use would be to pump
X hours of water to a tank and then have the pump shut down. Pressing
the
(R)
button will then repeat this process.
TRIP PRESSURE
Mode
1
The trip pressure can be set to any value from 0 to 2000 kPa or from 0 to
290 psi. The trip pressure must be set to some value that is less than the
start pressure. If the system pressure falls to below the set trip pressure,
it is the trip point that invokes the run-on timer and ultimately shuts the
pump down if pressure fails to recover. If you choose not to use the trip
pressure and leave it set to zero then the E30 reverts to operating like a
basic pressure switch. Its contacts will remain closed at all pressures that
are less than your set high pressure cut-out. If no pressure is present in
the system the contacts of relay 1 will be closed. No loss of pressure
protection will be provided by the E30 if it is set up this way.
START PRESSURE
Mode
1
The start pressure can be set to any value from 1 kPa to 2000 kPa or from
1 psi to 290 psi in increments of 1 kPa or 1 psi. Normally the start pressure
will be set to the pressure at which you want the pump to start. In normal
operation, each time pressure drops to whatever value you have set, the
pump will start. Once running the pressure can fall to below the value you
have set and the pump will continue to run. In fact, if you have not set the
trip pressure to some value greater than zero, the pump will continue to run
despite a complete lack of pressure.
The start pressure can be set as low as 1 kPa or 1 psi and the E30 will
function in the manner described. If you choose to set the start pressure
to zero you will invoke a warning message from the E30 to check your
pressure settings. The E30 will not tolerate having its start pressure set to
zero, in addition the start pressure must always be set to a higher pressure
than the trip pressure.
