Faults During Operation
If the inductive angular positioning system does not function correctly, refer to the table below
for possible causes and instructions for rectifying the problem.
Error
Possible cause
Action
"Power/Error" LED does not
light up
The power supply is switched
off.
Check whether there is a
reason for it being switched off
(installation or maintenance
work etc.). Switch the power
supply on if appropriate.
The cordset is not connected
to the connector on the
sensor.
Connect the cordset to the
sensor and tighten the union
nut by hand.
Wiring fault in the splitter or
control cabinet.
Check the wiring carefully and
repair any wiring faults.
Supply cable to the sensor is
damaged.
Replace the damaged cable.
"Power/Error" LED lights up
red permanently or
intermittently.
No actuator in the detection
area of the sensor or
unreliable detection of the
actuator.
Check that the actuator used
is mounted correctly or install
an actuator with appropriate
dimensions at the correct
distance from the sensor. (see
chapter 5.2).
Analog current output yields a
value of approx. 3.6 mA
No actuator in the detection
area of the sensor or
unreliable detection of the
actuator.
Check that the actuator used
is mounted correctly or install
an actuator with appropriate
dimensions at the correct
distance from the sensor. (see
chapter 5.2).
Actuator outside of
parameterized measurement
range.
Check that the position of the
parameterized measurement
range is correct.
Analog output does not reach
the maximum value
Sensor operating voltage too
low or load impedance out of
specification.
Check the operating voltage of
the sensor. Ensure that the
load impedance is within the
specified limits.see chapter
7.2
No output signal at the
switching output even though
the associated LED lights up
Output cable not connected
Connect the output cable
Output cable is short circuiting Rectify the short circuit
Output signal outside the
value range specified at the
analog output
Load connected only after the
sensor is switched on
Disconnect the sensor from
the supply voltage. Switch on
the sensor again
with
the load
connected.
Switching output signal
"chatters"
Use of a different actuator with
incorrect dimensions or an
incorrect distance to the
sensor
Install an actuator according
to specifications ()
Output signal unstable or
unreliable
Actuator rotating too quickly
Make sure that the speed of
the actuator is
≤
100
rotations/minute
