Series 2 Chain Conveyors
Note: The limit switch bracket must be oriented
as shown for proper engagement between limit
switch and Plug Relief Door.
Attach the bracket to the hood cover with two (2)
5/16” bolts and nuts where two pre-punched holes
are located. Two pairs of pre-punched holes are
provided on the removable head hood cover - one
pair on the left side and one pair on the right side
of hood cover. Next, use two (2) #10 machine
screws, nuts and washers to fasten the limit switch
to the bracket. The limit switch can be installed
either to the left or to the right. Do not tighten these
machine screws at this time.
Adjust the limit switch so that the actuator arm keeps
sufficient tension against the Plug Relief Door. Af-
ter the limit switch is properly positioned, tighten
the two machine screws.
Options
GSI Series 2 26” and 32” tall enmasse conveyors
come equipped with a head discharge plug relief
door as a standard feature. A NEMA 4 heavy duty
limit switch is standard on the relief door.
However, in extremely dirty, dusty conditions and/
or in enclosed environments, a NEMA 9 heavy duty
limit switch should be used on the plug relief door.
The NEMA 9 limit switch is available as an added
option.
The optional NEMA 9 limit switch (GSI part num-
ber CE-00504) attaches to the same universal
bracket on the front of the head assembly as the
standard NEMA 4 limit switch. The same hardware
is used for both limit switches.
