Overload safety device by others
When an overload safety device and thus the placement of the load sensors to measure
the rope forces are designed by others, all requirements relating to rope reeving, fleet
angle and angle of installation of the hoist must be observed, see chap. 4.2
The overload safety device must be set during commissioning, see supplementary
operating instructions.
The declaration of conformity/declaration of incorporation only apply to the manufacturer's
scope of delivery.
The overload safety device cannot be set by the manufacturer if it is provided by others.
4.9.10 Connecting to mains
Safety hazard. If this procedure is not observed, serious accidents or damage to the
hoist may occur!
1. Compare existing mains voltage and frequency with the information on the rating
plate.
2. Route cables into the hoist connection box through the cable glands.
3. Connect according to the circuit diagrams supplied.
4. Measure control voltage. If the measured value exceeds the rated control voltage by
more than 10%, a different tapping point must be selected on the primary side of the
control transformer.
5. Do not connect any live lead to the temperature sensors! Damaged temperature
sensors cannot protect the motor.
On three phase hoists, it is possible to have “Reverse Phasing” causing the block to lower
when the "UP" button is depressed. When this condition exists, the hoist operation will be
dangerous.
6. Check that the direction of rotation of the rope drum corresponds to the symbols on
the control pendant: Activate “slow up” button on control pendant. Never activate
“down” button first! If the hook moves upwards or does not move because the hoist
limit switch has disconnected in top hook position, the phase connection is correct.
7. Crosscheck by activating “slow down” button on control pendant.
8. If the movement of the hook does not correspond to the symbols on the control
pendant, interchange two phase conductors of the supply cable.
