in the crank arm closest to the end that mounts to the output
shaft. The overall length of the crank arm w/extension is now
25-5/8” from the center of the Output Shaft to the center of the
pivot at the “elbow.” Note that the crank arm w/extension if
required is adjustable and can be lengthened to a maximum of
31-5/8” long in (4) 1.5” increments. This may be required if the
gate bracket cannot be mounted in the position as previously
described. The prescribed installation procedure would be to
follow as outlined in these paragraphs, making adjustments as
needed.
Assemble the gate arm as shown in Figure 8, sliding the arm end
piece onto the end of the arm tube and tightening the 5/16-18 x
5/8 long square head set screws. Again as a matter of note, the
gate arm can be shortened (if necessary due to the gate bracket
placement, etc.) by cutting off a length from the tube. Attach the
gate arm to the crank arm extension and the gate bracket using
the 1/2-13 x 2 bolt (at gate bracket), the 1/2-13 x 2-3/4 bolt (at
the crank arm extension), the four 1/2 flat washers and two 1/2-
13 nylock hex nuts as shown in Figure 8. The gate arm is now
fully assembled with a total length of approximately 67-3/4”
With the Gate still immobilized in the closed position, the
"elbow" will be up against the closed position stop on the Crank
Arm Extension. At this time adjust the placement of the gate
bracket and/or the length of the crank arm/extension or gate arm
to ensure when the gate is fully closed the arm is in a straight
and locked position (from output shaft to gate bracket) as shown
in the left illustration in Figure 8.
Move the Gate to the fully open, 90 degree position as shown in
the right illustration in Figure 8. The crank arm/extension
should fold back over the arm as shown. If it doesn't, some
adjustment of the gate bracket or operator position may be
necessary. With the gate in the fully open position, adjust the
stop pall on the sprocket against the stop on the GS6000 frame
and tighten the set screw. Open and close the gate several times
until you are satisfied that the arm position is correct.
Finish welding or bolting the Gate Bracket to the Gate and
remove the C-clamps.
SETTING THE LIMIT SWITCHES
If you are resetting or checking the Limit Switches the cover must be
removed from the GS6000 operator, follow the procedure as outline
on page 25, to remove the gate arm from the output shaft then see the
first paragraph under
PLACING THE GS6000 OPERATOR
on
Page 8 to remove the cover. Reconnect the arm (if applicable) and
position the gate at it’s
FULLY CLOSED
position. If this is an
original installation the torque limiter adjustment nut is still
loosened, if resetting use the OPEN, CLOSE, and STOP buttons to
place the operator into position. Temporarily immobilize the gate in
this
FULLY CLOSED
position.
If this is a right hand (RH) installation (as shown in Fig. 8) the upper
switch is the Close limit switch, if this is a left hand (LH) mounted
operator (as shown in Fig. 6) the lower switch is the Close limit
switch. Referring to Fig. 11, loosen the clamping screw and nut and
the set screw on the Limit Switch Cam for the appropriate switch.
Rotate the cam on the output shaft (clockwise as you look at the shaft
from the control box if RH mounted, CCW if LH mounted) until it
engages the Limit Switch and an audible “click” is heard. If resetting
and the operator is under power the LED indicator on the control
board can be used as an additional indicator that the switch has
activated. Repeat this several times until you are confident that the
position of the cam is such that the Limit Switch is just closed.
Carefully tighten the nut on the Limit Switch Cam. Snug the set
screw on the cam against the output shaft to protect the cam from
accidental movement.
Remove the temporary immobilization from the gate and open the
gate to it’s
FULLY OPEN
position. Repeat the setting procedure
for the remaining Limit Switch and Cam, ensuring to rotate the Limit
Cam in the opposite direction from the rotation in the previous
paragraph, also see Figure 11.
If resetting or checking the Limit switch settings at this time reinstall
the operator cover and turret, reversing the removal procedure. If
this is an original installation, tighten the Torque Limiter adjustment
nut to an initial setting of 35 ft lbs and retighten the small set screws
on the nut facings.
ELECTRICAL HOOK UP
The GS6000 electrical connection is made in the CONTROL BOX
area, see Figure 12. Run a flexible water tight conduit from the
service junction box to the GS6000 CONTROL BOX. Route three
#14 wires (minimum size) from the service junction box in this
conduit to the GS6000 Control Box. If the GS6000 is wired for 115
Volts, route a black, white and green or ground wire. If the GS6000
is wired for 230 Volts, route a black, red and green or ground wire.
If the conduit has been pre-placed in the cement pad route these
wires (again using flexible conduit) up through one of the large holes
in the bottom operator plate and connect to the conduit hole on the
right side of the CONTROL BOX area.
