Electric Installation

Works on the electric installation may only be effected:
with cleared power supply

by trained and qualified electricians

Observe the regulations and standards of electric engineering.
In Germany, VDE regulations do apply.
Indication EMV
The electric wire rope winch with control is designed for industry.
The winch has to be switched at max. 5 times/minute to accomplish the standards for electromagnetic
emissions EN DIN 50081-2).
EMV proceedings (filter) have to be carried out if the winch has to be switched more than 5 times/mi-
nute or by using other electronic switching circuits (on site or delivered as option).
Electric control
Direct control
Limit switch
If limit position cannot safely be overlooked by the operator, operating limit switches have to be in-
stalled. The limit switches have to be integrated into the circuit in a functionally correct manner.
Depending on the application, i.e. for cranes etc., additional emergency limit switches are stipulated.
They have to be designed ac. to the respective standards and checked.
The manufacturer of the entire installation takes the responsibility.
With mounted-in limit switches, definitely check function in connection with the entire installation.
With wrong polarity or wrong connection, the limit switches are ineffective.
The winches are supplied with mounted gear limit switch
Attention:
Do not operate the winch until having adjusted and connected the limit switches!
Please observe:
 Depending on design the adjustment precision of the limit switch is approx. ±50mm. This cut off preci-
sion can only be kept in the first layer.
 The after running of the winch is approx. 1/100 up to 1/500 of the lifting speed [m/min].
 In any case, it has to be observed that the elongation of the rope may change the lift limit positions.
The remaining elongation of the rope up to replacement state of wear may be approx. 1 %.
 A regular check of the adjustment / turn-off ways is necessary.
Adjustment: Limit switch
1. loosen the fixing screws (04) and remove the cover (03)
2. for proper adjustment, loosen the central screw (07) of
the cam set, adjust the operating point of each single
cam by turning its screw (08) (the numbers on the
screws refer to the cams counting from bottom to top),
then tighten the central screw (07)
3. close the limit switch cover using the screws (04).
Tighten the screws (04) with a torque of 80/100 Nm.
Maintenance steps
– check the tightening of the cable clamp
– check the proper tightening of the screws and cover
– check that the limit switch is properly fixed
– check the limit switch enclosure is not broken
