Fault condition/Action required
Check the drive system with the test
switch located next to terminal 37. The
motor should accelerate to its maximum
speed. If the motor does accelerate to the
maximum speed when the test switch is
activated, the fault is external.
Is the control signal between 33(+) and
34 (-) present?
Have + and - been swapped?
The drive system has switched to a softer
speed controller because the motor shaft
is jerking sharply. Check that the drive belt
is not slipping on the pulley.
The exchanger rotor does not rotate;
check the drive belt.
The rotor rotates; check that the indication
is given when the magnet passes the
rotation sensor, see the section Operating
indicators, if not replace the rotation
sensor. If RotoSens is used, check that the
rotor or belt pulley are not smaller than
630 mm respective 63 mm.
Check function of the rotation sensor:
Measure with a Multimeter between
terminal 31 and 32, correct sensor
measures < 1 V when the magnet passes
the sensor.
The motor protection has been activated
due to excessive load. After a cool-down
period of 10 minutes the system restarts
automatically. If the overload protection
trips 3 times within 120 minutes the drive
system will be shut down, see also
overload (F5).
