Error Code Tro
ubleshooting
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: On A
dvanced motors, flow (K codes) and
pressure
(P codes) can be designated as alarms or
deviatio
ns. See Setup Screen 4, page 20.
NOTE: In the error codes listed below, an “X” means
the code is associated with the display only.
NOTE: In the e
rror codes listed below, a “_” in the
code is a plac
eholder for the number of the pump
where the eve
nt occurred.
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: A blink code of 9 is not an error code, but an
indicator of which pump is active (
softkey has
been pushed, see RunScreen1,page12).
