Errors/malfunctions
Sensor does not switch on:
When the shaft is stationary, the LED may not come on green. If BUS communication is nonetheless
not established, check the following:
•
The supply voltage Ub. The terminal voltage must be 9 to 36 V.
•
Whether the sensor (M12 connector) is correctly connected.
Sensor is flashing yellow:
This can occur when the shaft is stationary, even without an error. If the status occurs during
operation, check the following:
•
Whether the carbon brushes are in place
•
Whether the carbon brushes are worn out (no more contact with the slip ring)
No BUS connection possible:
Check the following:
•
Whether the sensor (M12 connector) is correctly connected.
•
Whether the resistance in the BUS circuit has a value of 50 Ω < R < 1500Ω. The terminal
voltage must be < 2 V when the sensor is connected.
•
The polarity of the BUS circuit (A and B wires reversed?)
•
The terminating resistors of the BUS system
If it is malfunctioning, replace the device. When you return the device for repair, please include
a
description of the malfunction that has occurred. Repairing the device on site is not appropriate
and is
therefore not intended.

Maintenance and repair
7.1
Maintenance
The sensor is largely wear-free.
The carbon parts of the slip ring collector wear out during use. There is no fixed maintenance interval
scheduled.
You will wee when replacement is necessary, as the sensor LED flashes yellow or you see a message
in
the Recorder software.
Repairs to the device may only be carried out by the manufacturer. If wear occurs on the slip ring
collector, the electronic housing of the sensor (black housing part of the sensor) in which the carbon
brush arms are located must be completely replaced.
If the sensor is opened or removed from the object to be monitored for maintenance or repair, the O-
ring seals of the sensor must be replaced.
