The VL917 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. To convert to a positive logic
interlock mode, follow the insturctions below. See
page 46 for negative logic mode hookup.
1. To connect remote interlock switch:
a. Relocate male plug 3-wire jumper from J6
(Negative) to J4 (Positive) position on circuit
board located inside pump module cover.
b. Install a female insulated spade terminal on
end of customer supplied remote interlock
+12V
source wire.
See Specifications below.
c. Mounded 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
+12V
source from remote interlock
into
red
wire supplied with insulated male
spade connector.
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).
