SLACK CHAIN SENSING SWITCHES – FLM & FLMC

(Ref. Figures 32, 33a & 33b)

The slack chain sensing switch kits have been shipped loose to be field mounted, wired,

and adjusted per the procedure below. These switches are intended to turn off the

motor and stop movement of the carriage whenever a slack/broken chain status is

sensed.

DANGER

To avoid personal injury or death, the procedures described in this section

should only be performed by qualified service personnel.

1. To install the slack chain sensing switches, first gain a safe access to the drive

base at the top of the masts. There is a slack chain sensing switch kit provided for

each lifting chain, (2) total.

2. With the carriage hanging from the chains, each tensioner arm will be pushing

towards the sensing switch arm. Each switch is wired to be normally open – held

closed.

a. Install each switch assembly onto its respective Unistrut channel as shown

in Figure 33a.

b. With the sensing switch arm mounted hanging down & tightened, slide the

sensing switch assembly in the Unistrut channel towards the tensioner

arm until the switch arm pushes against the tensioner arm and the

switches electrical contacts close (listen for the “click”). See Fig. 33b.

c. Tighten the two bolts holding the switch mounting angle to the Unistrut.

NOTE: To change the actuation direction of the switch, remove the switch head. Change

the actuating control knob/mechanism to the desired actuation direction.
