Pressure Transducer
Maintain Pressure. The engine will be throttled between the min. and max. RPM set points to maintain
this pressure. Factory set to 0 psi.
Deadband Pressure. This extends above and below the maintain set point, no throttling occurs while the
pressure is in the deadband. Factory set to 0 psi.
Pressure Maintain. Suction / Discharge. Suction starts on high, stops on low. Suction throttles by
decreasing the RPM below the deadband and increasing the RPM above the deadband. This is opposite
of Discharge pressure. Factory set to Discharge.
Steady / Proportional. Steady throttles the engine to the max. RPM set point when starting and stopping
on pressure. Proportional throttles the engine proportionally between the min. and max. RPM set points
when starting and stopping on pressure. 0 psi must be selected in the maintain pressure for the
steady/proportional features to work. Factory set to Steady.
Line Fill 1 Speed. The engine is throttled to this speed after warm-up to purge the line. Factory set to
900 RPM.
Line Fill 1 Delay. This is the time the engine is held at the Line Fill 1 speed. Factory set to 00.00.00.
Line Fill 1 Pressure. The engine is held at the Line Fill 1 Speed until either this pressure set point is
reached or the Line Fill 1 Delay expires. Factory set to 0 psi.
Line Fill 2 Speed. The engine is throttled to this speed after warm-up to purge the line. Factory set to
900 RPM.
Line Fill 2 Delay. This is the time the engine is held at the Line Fill 1 speed. Factory set to 00.00.00.
Line Fill 2 Pressure. The engine is held at the Line Fill 1 Speed until either this pressure set point is
reached or the Line Fill 1 Delay expires. Factory set to 0 psi.
Line Fill 2 features only available when Hose Reel is selected in the Applications menu.
Start Pressure. When the pressure reaches this set point, an auto start will occur. Factory set to 0 psi.
Stop Pressure. When the pressure reaches this set point, an auto stop will occur. Factory set to 0 psi.
Pressure P. Allows adjustment If using PID throttling. Factory set to 0.020
Pressure I. Allows adjustment if using PID throttling. Factory set to 0.020
Pressure D. Allows adjustment if using PID throttling. Factory set to 0.001.
Level Transducer
Maintain Level. The engine will be throttled between the min. and max. RPM set points to maintain this
level. Factory set to 0.0 ft.
Deadband Level. This extends above and below the maintain set point, no throttling occurs while the level
is in the deadband. Factory set to 0.0 ft.
Steady / Proportional. Steady throttles the engine to the max. RPM set point when starting and stopping
on level. Proportional throttles the engine proportionally between the min. and max. RPM set points when
starting and stopping on level. 0.0 ft must be selected in the maintain level for the steady/proportional
features to work. Factory set to Steady.
Level Type. Empty / Fill. Empty starts on high, stops on low. Empty throttles by decreasing the RPM
below the dead band, and increasing the RPM above the dead band. This is opposite of Fill. Factory set
to Empty.
Start Level. When the level reaches this set point, an auto start will occur. Factory set to 0.0 ft.
Stop Level. When the level reaches this set point, an auto stop will occur. Factory set to 0.0 ft.
Level P. Allows adjustment If using PID throttling Factory set to 0.020
Level I. Allows adjustment if using PID throttling. Factory set to 0.020
Level D. Allows adjustment if using PID throttling. Factory set to 0.001.
Flow Transducer
Start Flow Rate. When the flow reaches this set point, an auto start will occur. Factory set to 0 gpm.
Stop Flow Rate. When the flow reaches this set point, an auto stop will occur. Factory set to 0 gpm.
Maintain Flow.The engine will be throttled between the min. and max. RPM set points to maintain this
flow. Factory set to 0 gpm.
Steady / Proportional. Steady throttles the engine to the max. RPM set point when starting and stopping
on flow. Proportional throttles the engine proportionally between the min. and max. RPM set points when
