125% FIELD LOAD TESTING / OVER-WEIGHT BYPASS
Each hoist is factory load tested prior to shipment. If a field load test is required, you will need to bypass the over-weight signal.
To bypass the over-weight signal, locate the bypass terminal knife disconnect it should be labeled “BPS” (use images below as
reference) and pull the yellow/orange tab to open.
IMPORTANT - Be sure to close the over-weight bypass terminal knife disconnect “BPS” after the load test is complete, failure to do
so may result in damage to the hoist in the case of an overload.
NOTE – Detroit Hoist recommends that 125% load tests should only be conducted by operating the hoist in low speed when the
125% load is suspended or the VFD may fault.
