6-2 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 4, which cover operation procedures.
Name Description Options Default
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. 0–999 sec. 45 sec.
Alarm Options
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. disabled,

Blow Back Options
Blow back When this option is enabled, the controller
periodically sends compressed air backward through
the pump’s air filter to dislodge accumulated dust and
debris.
Enable this option if and only if the pump has the
equipment for compressed-air filter cleaning. disabled,

Every n loads Number of conveying cycles to stations between filter
cleanings.
Adjust this setting based on experience. The more
dust and debris in your material line, the smaller this
number needs to be. 1–99 5

pump’s filter during cleaning.
If filter-cleaning is not working as desired, the service
department may ask you to change this setting. 1–99 5
On time Number of seconds that the air compressor remains
on for each pulse during filter cleaning.
If filter-cleaning is not working as desired, the service
department may ask you to change this setting. 0.1–99.0 sec. 1.0 sec.
Off time Number of seconds between air pulses during filter
cleaning.
