Signal Explanation Possible remedy
04 Local blocked
Status signal only!
Localcontrolcanbedisabledviaeldbus.Incaseofa
eldbuscommunicationerror,localcontrolisautomatically
re-enabled.
05 REMOTE commissioning
Status signal only!
Actuator is commissioned in REMOTE mode.
Wait for termination of commissioning in RE-
MOTE mode.
11 Motor temp� too high
The motor has exceeded the maximum temperature of
155°C.
Possible reasons:
■
Excessive ambient temperature,
■
Excessive runtime,
■
Too many switching cycles.
■
Actually required torque too high or
■
Short- circuited motor coil or connection to the motor tem-
perature sensor interrupted (2SG7 only).
■
Parameterforseparatemounting">10mwithlter“not
set.
Note: The motor temperature monitoring can
be deactivated by programming at the actuator
(plant protection has priority over motor protec-
tion). However, the warranty for the actuator
immediately becomes void.
■
Check operation conditions, valve as well as
motor;
■
Check "Separate mounting“ parameter.
12 Overvoltage
Mains voltage too high (outside the tolerance +15 %).
■
Check connection voltage,
■
Check mains voltage for variations.
13 Undervoltage
Mains voltage too low (outside the tolerance –30 %).
■
Check power supply!
■
Check mains voltage for variations!
14 Power supply fault
Power supply failed or too low.
■
Check power supply!
■
Check connecting cable!
21 Run time error
After 3 % of the positioning time, the actuator has covered
less than 0.5 % travel. The positioning time is measured and
saved following the end position adjustment.
Possible reasons:
■
Potentiometer contacts in the plug/socket connector were
ejected.
■
Incorrect assembly and/ or setting of the potentiometer
after replacement.
■
Motor cable interrupted (motor is not running).
■
Error during position recording (the gear backlash between
potentiometer and central wheel is either too small or too
large: No change of position is detected although the motor
is running.)
■
Signaling gear ratio was changed:
– Signaling gear turns in the opposite direction or
– Setting of the slide wheel (rev/stroke) in the signaling
gear is too high
■
Actuator is blocked (actuator cannot be operated from
position/end position).
■
Faultypotentiometer(lmisinterrupted).
■
Parameterforseparatemounting">10mwithlter“not
set.
■
Check valve, signaling gear, motor as well as
potentiometer!
■
Check "Separate mounting“ parameter.
22 Process Interlock
STOP input is active. Only for binary control mode “Pulse
contact”.
Deactivate STOP input. Refer to chapter „8.3.3
Control system – Control mode“ on page 67.
