DISPLAY MESSAGE DESCRIPTION
DEFAULT/MIN
/MAX VALUE
OVERPRESSURE
psi
This value is added to the value set by parameter psi SETPOINT. The
combined value is the pressure at which drive will stop the motor load.
Motor will restart when the pressure falls to the value set by parameter
DRAW DOWN PSI .
20/0/500
4-20mA PSI
SENSOR RANGE
As psi. This value should be set to the maximum psi of the 4-20 mA
transducer being used for constant pressure control i.e. if the
transducer has a range of 0-150 psi the parameter should be set to 150.
This parameter is critical for accurate pressure control.
150/50/500
DUPLEX CYCLE
TIME
As hours. This value will determine how long each pump will run before
switching to the next pump in the system.
0/0/9999
DRAW DOWN PSI
As psi. Provides hysteresis during sleep mode. Parameter controls the
pressure drop below
psi SETPOINT to start motor in sleep mode, e.g. if
psi ON = 5 and motor turns off at 50 psi, motor will restart at 45 psi.
5/0/50
psi SETPOINT
As psi. This sets the level at which the pressure will be controlled. Must
be set as a psi value within the range of the 4-20 mA transducer. Make
sure the value of the parameter
4-20mA psi SENSOR RANGE is set to
the maximum psi value of the sensor you are using. Make sure the
proper
SYSTEM CONFIG has been set for CP control. See Section
6.5 , System Configuration , for details. See Section 7 , Constant
Pressure Systems , for instructions on using advanced control options.
