Adjustment of the time-delay mechanism of sensor MS 45R:
The standard time-delay of sensor MS 45R, set by the manufacturer, is 30 seconds.
We recommend, NOT to shorten the set time-delay. The duration of the time-delay can
be activated by pushing and releasing buttons A and B simultaneously. The mode
indicator has to be red. Each time button A is pushed, the time-delay is increased by 1
minute, each time button B is pushed, the time-delay is increased by 1 second.
Example: A time delay of 10 min and 5 sec means, that button A has to be pushed 10
times and button B 5 times.
Adjustment of the sensitivity of sensor MS 45R:
The sensitivity can be activated by pushing and releasing buttons A and B
simultaneously. The mode indicator has to be green. When pushing button A the
sensitivity is decreased, when pushing button B it is increased.
If the sensor MS 45R does not interrupt the current supply to the drive, the sensitivity
has to be increased.
If the Sensor MS 45R does not react and the motor of the drive does not start, the
sensibility has to be reduced.
Reset to factory settings:
To reset to manufacturer’s settings (30 seconds), buttons A and B have to be pushed
simultaneously for at least 15 seconds.
Sensor MS 45R has an adjustable time-delay of 0-240 minutes.
The sensors’ distinct reactivity ensures that varying moistness of the feed
changes the set-time. For the adjustment, the feed should be as dry as
possible. The drier the feed, the more secure the switching function of the
sensor MS 45R.
