Troubleshooting
Error codes can take three forms:
• Alarm
: alerts you to the alarm cause and shuts
down the pump.
• Deviation
: alerts you to the problem, but pump
may continue to run past the set limits until the
system’s absolute limits are reached.
• Advisory
: information only. Pump will continue
to operate.
NOTE:
NOTE:
NOTE: On Advanced motors, flow (K codes) and
pressure (P codes) can be designated as alarms or
deviations. See
.
NOTE:
NOTE:
NOTE: In the error codes listed below, an “X” means
the code is associated with the display only.
NOTE:
NOTE:
NOTE: In the error codes listed below, a “_” in the
code is a placeholder for the number of the pump
where the event occurred.
NOTE:
NOTE:
NOTE: The blink code is displayed using the power
indicator on the motor. The blink code given below
indicates the sequence. For example, blink code 1–2
indicates 1 blink, then 2 blinks; the sequence then
repeats.
NOTE:
NOTE:
NOTE: A blink code of 9 is not an error code, but an
indicator of which pump is active (
softkey has
been pushed, see
).
