Display Display Description Description
THROTTLE
READY
This displays when the throttle ready interlock input is active and the pump engaged interlock is inactive.
PUMP NOT
ENGAGED
This displays when you press the pressure button to enter pressure mode and the pump engaged interlock input is inactive.
PUMP
ENGAGED
This displays when the pump engaged interlock input is active and the throttle ready interlock is inactive.
OK TO
PUMP
This displays when the both the throttle ready and pump engaged inputs are active, or the OK to pump input is active, and the OK to pump
configuration is set to OK2pump.
DISCHARGE
SENSOR LOW
This displays when the discharge sensor signal voltage is less than 0.3VDC.
DISCHARGE
SENSOR HIGH
This displays when the discharge sensor signal voltage is more than 4.9VDC.
INTAKE
SENSOR LOW
This displays when the intake sensor signal voltage is less than 0.3VDC.
INTAKE
SENSOR HIGH
This displays when the intake sensor signal voltage is more than 4.9VDC.
PRESSURE
LIMITED
In speed mode, this displays when the pump pressure increased greater than the pressure limit configuration parameter from the initial
pressure when mode was started. Refer to the PRESS LIMIT parameter in
"Configuration Settings" on page 40
RPM LIMIT
NO PRESS INC
In pressure mode, this displays when the engine speed increases are limited, because the last 200RPM engine speed increase did not raise
the pump discharge pressure.
NO WATER
SUPPLY
In speed mode, this displays when the pump discharge pressure is less than 15PSI.
LOW
WATER SUPPLY
In pressure mode, this displays when the engine speed has increased and the discharge pressure has decreased, or pump intake sensor
pressure is below the low limit.
PRESSURE
DROPPED
In pressure mode, this displays when the discharge pressure was above 50PSI and then dropped below 30PSI.
PRESET NOT
ALLOWED
This displays when the preset button is pressed in speed mode, and allow preset parameter is configured as NO. Refer to the ALLOW
PRESET parameter in "Configuration Settings" on page 39 .
ALARMS
