Troubleshooting
Device Hardware Fault
0x5000
The event occurs when a
hardware fault is detected.
Fault in valve position
detection.
–
Contact GEMÜ Support
Parameter can no longer be
read when switching the
device on.
Motor Unable To Move
0x8CE0
The event occurs when the
motor is blocked.
Valve is blocked (for example,
solid stuck in valve).
–
Check valve
–
Carry out initialization
if valve is OK
Valve corroded (rusted in
place).
End position can no longer be
reached (after replacing the
diaphragm).
Device Temperature Over-Run
0x4210
The event occurs as a warning
or error if the motor
temperature is too high.
Control is operated outside of
the specification.
–
Check temperature
–
Set control correctly
(check duty cycle (ED)
of the actuator)
The ambient temperature is
too high.
Emergency Power
0x5100
The event occurs if the supply
is too low. The event is
triggered as a warning if the
supply voltage Uv is below a
value of 21.1 V. (If the supply
voltage is below 17.4 V, the
event Primary Supply Voltage
Under-Run (0x5111) is
triggered as an error).
Power supply unit overloaded.
–
Check supply
Cross-section of the supply
line is too small.
Supply line is too long.
Primary Supply Voltage
Under-Run
0x5111
The event occurs if the supply
voltage is too low.
Power supply unit overloaded.
–
Check supply
Cross-section of the supply
line is too small.
Supply line is too long.
Potifail Close
0x8CA5
The event occurs if a valve
position is read which can
never be achieved in the
"Close" direction.
Fault in valve position
detection.
–
Check valve/diaphragm
Error when replacing a
diaphragm (stroke of the valve
in incorrect area).
Actuator has been fitted on
the valve incorrectly (stroke of
the valve in the incorrect
area).
Potifail Open
0x8CA4
The event occurs if a valve
position is read which can
never be achieved in the
"Open" direction.
Fault in valve position
detection.
–
Check valve/diaphragm
Error when replacing a
diaphragm (stroke of the valve
in incorrect area).
