Low/Empty Limit Switch
Replacement
To replace the Low/Empty Limit Switch, perform the
following steps:
1. Perform the System Shutdown procedure provided
by the integrator at the applicable Supply Unit (LH
or RH).
2. Shut off power to the Junction Box Panel (H).
NOTE:
The first limit switch closes when the Follower
Plate (D) reaches the preset low limit level in the drum.
The second limit switch closes when the Follower Plate
(D) reaches the preset empty level in the drum. Both
limit switches provide inputs to the PLC interface.
Switch Removal
3. Between the two limit switches (305), locate the
faulty switch. See F
. 26.
4. Disconnect the wiring (301) for the limit switch at its
power source. For reference, use the wiring
diagram shown in F
5. Mark the surface on the ram limit bracket using a
felt-tipped pen to ensure that the new lower limit
switch is installed in the same spot.
6. Measure the distance from the mounting bracket
(306) to the outer diameter of the limit switch roller
to ensure that the new roller is installed in the same
position.
7. Remove three cap screws (302), the lock washers
(303), the plain washers (304), and the limit switch
(305) from the limit bracket (306). See F
During operation, keep hands and fingers away from
Limit Switches (S) to reduce the risk of pinching or
amputating hands or fingers.
All electrical wiring must be done by a qualified
electrician and comply with all local codes and
regulations.
Installing and servicing this equipment requires
access to parts which could cause an electric shock
or other serious injury. Have only qualified electricians
access the control assembly.
