Note:
Moving / rocking whilst stopped can result in the "overload"
buzzer being activated or the warning light coming on. No over-
load is present if the buzzer or the warning light switches off as
soon as the man riding equipment stops moving.
– Let down or release load.
– Stop hoist:
The hoist must hold the wire rope tight.
If the hoist does not hold the wire rope tight:
– Press the EMERGENCY-STOP button.
– If the EMERGENCY-STOP button fails, disconnect the hoist
power supply (e.g. by pulling out the plug).
– Have the hoist inspected and serviced by an electrician or
authorized service personnel (see ' 15.1 Authorized mainte-
nance personnel' on page 20).
Function test of the Emergency-stop
– Let the hoist run in the pulling direction.
– Press the EMERGENCY-STOP button.
The power supply for the motor must be switched off.
The hoist must hold the wire rope tight.
– Release the emergency stop button again.
Testing the limit switch
In order to avoid unnecessary checking, please transfer your
marked list from chapter ' 18 Limit switch overview' on page 28
here by marking the respective titles.
1)  Check the load limiting device
The operator is obliged to fit the load limiter before starting the
hoist (see ' 15.5 Adjustment, Adjusting the mechanical load limit-
ing device' on page 23).
The check is carried out in the scope of the setting.

2) Check the emergency limit switch UP
– Trigger the emergency limit switch manually:
The power supply for the motor must be switched off.
The hoist must hold the wire rope tight.
You should not be able to move up or down.

3) Check the operating limit switch UP
– Trigger the optional operating limit switch by running on to it:
The upwards movement must be stopped.
The hoist must hold the wire rope tight.
Downwards movement must still be possible.


4) Check the phase sequence relay
(3-phase monitoring)
If the limit switch does not switch off the drive when switching the
hoist on for the first time and the hoist travels in the correct direc-
tion when pressing the UP button, then everything is OK. If the
direction of rotation is incorrect, use the phase reverser, see
fig. 13.

5) Check hand crank limit switch
– Move the hand crank into the operating position (see
' 10.4 Emergency descent' on page 17).
The load must not descend.
The power supply for the motor must be switched off.
– Turn the hand crank to the right after the operating brake
has been released:
The load will be raised.
– Turn the hand crank to the left after the operating brake has
been released:
The load will be lowered.
The power supply is reactivated.

6) Check the slack rope switch
– Lower the load or run the wire rope out:
The first rope turn must always remain on the rope reel.
– Turn the rope reel against the winding on direction until the
wire rope slackens and the limit switch is activated.
– Switch the hoist on in the DOWN direction.
The hoist must not be switched on.
– Switch the hoist on in the UP direction.
The upwards movement must still be possible.
– Turn the rope reel manually until the wire rope is taut and
the limit switch de-activates.

7) Test the limit switch DOWN
– Trigger the limit switch manually or by running on to it.
The downwards movement must be stopped.
The hoist must hold the wire rope tight.
You must not be able to move downwards.

8) Check the rope limit switch
– Lower the load or run the wire rope out as far as possible:
The limit switch of the rope must trigger when the first turn
of the wire rope is still wound around the rope reel.
– Switch the hoist on in the DOWN direction.
The hoist must not be switched on.
– Switch the hoist on in the UP direction.
The upwards movement must still be possible.
