Troubleshooting the Graco Motor Control
Event
Code
Event Level
Description
Solution
F2DP
Deviation
The motor control limit has been
reached and Max Power Mode is
enabled in menu G204. The controller
is at maximum line current, maximum
motor current, or maximum output
voltage, but the motor will continue to
run at a reduced performance.
Reduce pump flow/pressure.
F2DT
Deviation
The motor temperature is above
120°C(248°F) and Max Power Mode
is enabled in menu G204. The output
current is being limited, but the system
will run at a reduced performance.
Reduce pump flow/pressure or duty
cycle.
K4E0
Alarm
The motor speed has exceeded the
maximum.
Event will clear after acknowledgment.
Check operating conditions to
determine the source of the alarm.
K6EH
Alarm
The position sensor has read an
invalid position, likely because it is not
connected.
Ensure the feedback cable is correctly
installed and away from any external
noise sources.
K9EH
Deviation
Position errors (skips, momentary
invalid positions) have been detected.
Likely due to noise on the motor
feedback cable.
Ensure the feedback cable is correctly
installed and away from any external
noise sources.
L3X0
Deviation
The pump leak sensor has detected
a leak and the Pump Leak Type is
set to Deviation in G206. The pump
continues to run.
Replace worn parts to stop leak, drain
leak sensor and replace.
L4X0
Alarm
The pump leak sensor has detected a
leak and the Pump Leak Type is set to
Alarm in G206. The pump has been
stopped.
Replace worn parts to stop leak, drain
leak sensor and replace.
MA01
Advisory
The maintenance pump cycles have
exceeded the number set on menu
G230.
Clear the Maintenance Counter (menu
G130).
MA02
Advisory
The maintenance pump cycles have
exceeded the number set on menu
G231.
Clear the Maintenance Counter (menu
G131).
MA03
Advisory
The maintenance pump cycles have
exceeded the number set on menu
G232.
Clear the Maintenance Counter (menu
G132).
T3E0
Deviation
The internal motor temperature is
above 100°C(212°F).
Reduce pump flow or duty cycle.
T4C0
Alarm
The internal IGBT module temperature
has exceeded the limit of 100°C
(212°F).
Reduce power output or decrease
ambient temperature.
T4E0
Alarm
The internal motor temperature is
above 150°C(302°F) and Max Power
Mode is disabled in G204.
Reduce pump flow or duty cycle.
Enable Max Power Mode (G204).
