7-2 Options for Pump Setup

Several of the items in this screen are not setup options but

are instead intended for use during operation. These items

(hour meter and transferring stations to a standby pump) are

described in Chapter 5, which cover operation procedures.

Name Description Options Default

Idle Time Options

1 Idle time Length of time the pump continues to run unloaded
without demand from any station. After this time has
elapsed, the pump shuts down to save power and to
prevent wear on the pump.
Adjust this setting to fit the needs of your facility
in trading off the energy savings against the
costs associated with waiting for a pump to start
up when there is a demand for material.
0–999 sec. 45 sec.

Alarm Options

General Pump fault The control has one input/pump that you can wire to
generate alarms for situations of your choosing. For
example, you may have a sensor that turns on when
material reaches the top of a filter-chamber waste
bin. When this option is enabled, the controller issues
an alarm if the sensor wired to the input for Pump
Fault turns on.
Enable this option if and only if your facility has
installed a miscellaneous alarm on the input for
Pump Fault for this pump.
