The batch controller allows you to have the pump run for a set period of time and

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 reset button

on the E30 will then repeat this process.

If pressure rises to above the E30’s set high pressure cut-out point while the batch

is running the E30 will shut the pump down on high pressure and wait for the

pressure to fall to whatever you have set the starting pressure to. When the pump

restarts the batch controller will restart its run from 1 minute less than where it left

off. If you choose to use delayed restarting in conjunction with the batch controller

then the batch run will resume from 1 minute less than where it stopped at as

soon as the delayed restart period ends.

If pressure is lost when batch running and delayed restart is not used the E30 will

time out on its run-on timer and then shut the pump down and go into dry run

alarm. Batch running will only then recommence once you press reset or reset

the power to the E30. No knowledge will be retained as to where in its batch run

it was when ow was lost. The batch run in this situation will recommence from

the beginning of the set time.

Mode 1 Trip Pressure

The trip pressure 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 trip

pressure must be set to some value that is less than the start pressure. If the

system pressure falls to below your set trip pressure during normal operation, it is

the set trip point that invokes the run-on timer and ultimately shuts the pump down

if pressure fails to rise above the trip pressure by the end of the run-on period.

The trip pressure can be set to 1 kPa or 1 psi less than your start pressure or it

can be set substantially less than the start pressure.

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 the E30 will be closed. No loss of pressure

protection will be provided by the E30 if it is set up this way.

The trip pressure can be set as low as 1 kPa or 1 psi and it will provide loss of

pressure protection to a pumping system but it is important to remember that if it

is set to zero no low pressure protection will be provided by the E30.
