5.2.10 Lower Limit/Upper Limit Bypass MFDI
The Limit Bypass allows for the following without the use of jumpers or re-programming parameters:
1. Ease of testing of the Weighted Upper Limit Switch (UL3) or re-homing the Height Measurement
function, and
2. To allow changing of the wire ropes, i.e. spooling all the rope off of the hoist drum.
NOTE: The momentary key-switch to operate this function 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.
