Pressure Errors
NOTE: In some error codes listed below, a # symbol is shown as the last digit. This symbol represents the
applicable component number, which can vary. The unit's display will show the applicable number as the
last digit in the code. For example, the P6F# code listed in this table will be displayed as P6F1 if the affected
component is pump 1, P6F2 for pump 2, and so on.

the user-entered alarm
limit.
The inlet pressure on
pump # is less than the
user-entered deviation
limit.
The outlet pressure
on pump # is greater
than the user entered
deviation limit.
The inlet pressure
on pump # is greater
than the user-entered
deviation limit.
The outlet pressure on
pump # is greater than
the user entered alarm
limit.

the pressure is above
the readable range.
Solution
Verify transducer is
connected properly.
Replace if reconnecting
does not eliminate the
alarm.

Replace if reconnecting
does not eliminate the
alarm.
Relieve system
pressure. Verify
connections, or replace
if reconnecting does
not eliminate the alarm.
