Hall
Choose Hall if a Hall effect sensor is connected.
VR
•
Choose VR if a variable reluctance sensor is connected
Sensor monitoring
The checkbox Sensor monitoring is available when Hall or VR has been selected as sensor
type.
Place a checkmark in the box to activate the supervision of the connected sensor. Eddy
current sensors are always supervised. When activating this function for Hall effect
sensors, ensure that the necessary resistance network is connected to the sensor input.
See
Sensor
At VR sensors: The channel supervision only checks whether a VR sensor is connected or
not. This supervision is active when a checkmark is placed in box Sensor Input → Sensor
monitoring and machine standstill has been detected.
Click Set default values to set the values in group Measured quantities to the default
values according to the selected sensor. Values not corresponding to the selected sensor
are red colored.

Upper sensor voltage limit and Lower sensor voltage limit
Define here the limit for the sensor supervision. The sensor input voltage must be within
the defined range. If the sensor voltage is out of this limits Channel OK is switched off. For
more details see
recommended sensor voltage limits.

must be lower than the

The lower sensor limit value
must be higher than the
minimum possible sensor
level. This avoids the
switching off of Channel OK if
the sensor detects a tooth
gap.
