5.2.10 Upper/Lower Limit Bypass
The Limit Bypass allows for the following without the use of jumpers or re-programming parameters:
1. Ease of testing the Weighted Upper Limit Switch (UL3) or re-homing the Hook Height.
2. To allow changing of the wire ropes, i.e. spooling all the rope off of the hoist drum.
NOTE:
A momentary key-switch is recommended to operate this function and should only be accessible to
maintenance personnel, not the crane operator. A functional description and usage procedure should be
included in an administrative control program to avoid confusion and potentially have the End of Travel
Limit switches left in a bypassed state during normal operation of the crane.
