Error Code Troubleshooting - Graco E-Flo DC Series Instructions - Parts Manual

Error Code 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: On Advanced motors, flow (K codes) and
pressure (P codes) can be designated as alarms
or deviations. See Setup Screen 4 in the Control
Module Manual.

NOTE: In the error codes listed below, an "X" means
the code is associated with the display only.
NOTE: In the error codes listed below, a "?" in the
code is a placeholder for the unit number where the
event 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 (
has been pushed, see Run Screen 1 in the Control
Module Manual).
