Signal Explanation Possible remedy
37 Move to xed setpoint
No signal from signal source (wire break).
Fixed process setpoint is approached and maintained
The actuator can be operated in "LOCAL“ control (e.g. hand
wheel, emergency operation, alternative control mode).
Check cables/contacts in the round plug.
38 No AI2 signal
This indication is only possible for live-zero setting
(4 – 20 mA).

one or both sides.
Check feed cables or contact points!
41 No signal motor temp�
Connection to the temperature sensor interrupted Check feed cables and contact points of elec-
tronics/gear!
42 No signal potentiometer
No data received from the potentiometer.
■
Check feed cables and contact points of
electronics/gear!
■
Check feed cables for separate installation.
■
Replace signaling gear.
43 No signal position encoder
No data received from the non-intrusive position encoder
(niP).
■
Check feed cables and contact points of
electronics/gear!
■
Check feed cables for separate installation.
■
Replace non-intrusive position encoder.
44 End position overrun
Position of the central wheel is too close to the mechanical
end stop of the signaling gear.
■
The end positions have been exceeded by hand wheel
operation or
■
The friction coupling in the signaling gear was twisted or
the signaling gear ratio was changed.
End position re-adjustment required.

45 No signal standstill sensor
No data received from the standstill sensor.
■
Check feed cables and contact points of
electronics/gear!
■
Check feed cables for separate installation.
46 Analog add-on module
No signal received from additional analog module.
■
Check ribbon cable to analog module.
■
Switch voltage on/off (AC/DC).
If the indication is still displayed, replace elec-
tronics unit.
47 Failure HART Comm�
Analog module defect. No HART communication possible. Switch voltage on/off (AC/DC).
If the indication is still displayed, replace elec-
tronics unit.
