6-3 Options for Pump Setup

during operation. These items (hour meter and transferring stations to a standby pump) are
described in Chapter 4, “Operation.”

Idle Time Options
Auto shutdown delay 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 savings against the costs
associated with waiting for a pump to start up
when there is a demand for material.
