Lower Limit/Upper Limit Bypass Mfdi - Magnetek Impulse G+ series 4 Instruction Manual

Lower Limit/Upper Limit Bypass MFDI

The Limit Bypass allows for the following without the use of jumpers or re-programming of the drive
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.
