Lift Interlock Installation
The CL917 can be configured for use with a cus-
tomer-supplied remote interlock with either a +12V
signal (positive logic) or a ground signal (negative
logic). The lift is shipped ready to use in the nega-
tive logic mode. Below are the instructions for
proper negative logic (grounded) interlock installa-
tion. To convert to a positive logic interlock mode,
follow the instructions on supplement page 5.
(When installing a remote interlock that supplies a ground signal)
1. To connect remote interlock switch:
a. Verify male plug 3-wire jumper is in the J6
(Negative) position on circuit board located
inside pump module cover.
b. Install a 1/4" insulated female spade terminal
on end of customer-supplied remote interlock
ground
source wire.
See Specifications
below.
c. Mounted to the pump module cover is a
female interlock plug. Exiting the back side
(inside pump cover) is a black and red wire
with 1/4" insulated male spade terminals.
d. Plug the
ground
source from customer-
supplied remote interlock with the 1/4" insu-
lated female spade connector into the 1/4"
insulated male spade connector on the black
wire exiting the back side of the female inter-
lock plug.
e. Remove male interlock jumper from front of
pump module cover. Store in glovebox for use
if needed when troubleshooting interlock
circuit.
Note:
Installing male interlock jumper
(
e
) will bypass customer-installed interlock
circuit and allow lift operation.
2. With lift unoccupied, test all lift functions to ensure
proper interlock installation
(with interlock switch
opened and closed).
