Control System Operations Manual AGE Page 23 of 129
4.7 System Maximum Operating Pressure (PSI):
This value determines at what maximum outlet pressure the system will allow the high pressure pump
to operate. Operation above the inputted value triggers an instant shutdown of the system. Setting this
value too high can severely damage the high pressure pump motor, as there is not enough available
horsepower to drive the high pressure pump beyond these limits. This causes rapid overheating of the
high pressure pump electric motor, and eventual failure of the motor. This type of damage is not
covered by warranty should these settings report being changed by the user, if the control system is
connected to a CAT pump this value should remain the same.
Typical values entered here are 975 PSI in all pump applications
4.8 Maximum Membrane Health DP (PSI): (if PT-1005 fitted only)
This value determines at what maximum differential pressure the system will allow the membrane chain
to operate. Detection of pressures above the number inputted here will result in performance warnings
(See Performance Warning Messages), stating an excessive membrane pressure differential. This will not
cause a system shutdown, but it is advisable upon seeing these warning messages to perform a chemical
cleaning of the system to remove scaling.
Typical values entered here are 45 PSI in all applications
4.9 Maximum High Pressure Pump Hours:
The value here determines at what number of operational hours the water maker will call for high
pressure pump servicing. Once the entered number of hours is exceeded the system will raise a
performance warning (See Performance Warning Messages), stating the high pressure pump is due for
servicing. Operation over these hours is allowed, but is not recommended.
Typical values entered here are 8000 Hrs in Danfoss pump applications
Typical values entered here are 2000 Hrs in CAT pump applications
