INSTALLATION INSTRUCTIONS
F. INSTALLING LEVEL/LIFT STATUS LIMIT SWITCHES
Items needed:
Qty
Description
Varies 1 N.O. – 1 N.C. Limit Switch Kits (depends on interlock style & Qty)
1 2 N.O. – 2 N.C. Limit Switch Kit
1 Maintained Contact Limit Switch Kit (for mid-level on 3-level applications
only)
Level limit switch Kits (quantity depends on application – typically one (1) 2N.O.-2N.C.
limit switch on second level, and (1) 1N.O.-1N.C. switch on first level (when equipped
with solenoid interlocks), have been shipped loose to be field mounted, wired, and
adjusted to sense the status/position of the lift carriage per Figure 21.
1. Locate, mount, and wire the level limit switches (shipped loose) on the adjustable
Unistrut mounting plates located at upper and/or lower locations on the back of the
mast pair. Again, depending on the types of interlocks used, there is either one or
two switches to install.
2. Once assembled, adjust the limit switch arm to make contact with the limit switch
cam when the carriage is at that corresponding level – leaving room for adjustment.
3. For best results in adjusting position of the switch, loosen the mounting bolts that
hold the switch to the Unistrut channel just enough so that the switch can be lightly
“tapped” into position. It is extremely difficult to loosen the bolts completely and
adjust the switch.
DANGER!
Never go under a platform! To avoid personal injury or death,
be sure the platform has been blocked from underneath! See
“Blocking Instructions.”
