General
x
Do not place or drop the pendant in water.
x
Do not let the pendant slam into objects or people.
x
Do not move switches beyond their travel limits.
Regular Pre-Operation Inspection – Perform at least monthly
Before using a pendant station:
x
Ensure that the unit’s exterior is in good condition with no cracks or sharp edges. Button marking
should be legible on all buttons.
x
Ensure that the buttons function normally and that the detents clearly indicate how far the button
has been depressed. Make sure that buttons return to the OFF position when released. Check
that the mechanical interlocks on two button switches are working. Pushing on one button all the
way down should prevent its twin from being pressed down.
x
Remove any dirt from the outside of the pendant.
x
Ensure that the cable is not cut or damaged.
x
Ensure that the cable entry point is well sealed.
x
Ensure that there are no cracks, cuts or openings in the flexible button hoods.
x
Shake the pendant to tell if there are any loose items or water inside. Have a qualified
maintenance person investigate if something sounds loose or you are in doubt.
x
Ensure that the strain relief cable supports the pendant properly. The strain relief system should
be strong enough to support an operator if they stumble while operating the pendant and use it to
steady themselves. Under no circumstances should a force applied to the pendant be transferred
to the current carrying conductors of the pendant cable.
x
The pendant should be hung at a height of approximately 42 inches from the floor, where it will be
convenient for the operator to manipulate its switches. If the operator has to bend to grab the
pendant, it is likely hung too low.
