D: STARTING THE OPERATOR
Manually push the gate all the way open again. Following the
procedure shown in Figure 17, mount the Limit Cam on the chain
link that was marked with chalk in the previous step, the link
should now be parallel with the ground and approximately 4 to 5
feet from the end of the gate. The cam MUST BE mounted such
that the lobe is DOWN (TOWARD THE GROUND).
NOTE: IF RIGHT-HAND OPERATION (STANDARD)
MOUNT THE CAM WITH THE STUD/NUT POINTING
AWAY FROM THE GATE, IF LEFT-HAND OPERATION
MOUNT THE CAM WITH THE STUD/NUT POINTING AT
THE GATE.
NOTE: ENSURE THAT WHEN THE CAMS ENTER THE
LOWER IDLER SPROCKETS THEY ARE ORIENTED
PROPERLY AS FOLLOWS: WHEN THE CAM ROUNDS
THE INSIDE SPROCKET (CLOSEST TO THE PEDESTAL)
ITS STUD/NUT SHOULD BE POINTING TOWARDS THE
PEDESTAL, WHEN THE CAM ROUNDS THE OUTSIDE
SPROCKET (FARTHEST FROM THE PEDESTAL) ITS
STUD/NUT SHOULD BE POINTING AWAY FROM THE
PEDESTAL.
The limit cams are now roughly adjusted. If the gate should stop
short of fully opened or closed, or if it bangs against the end stops
during operation, the limit cams can be fine-tuned after the
operator is powered up. (See FINAL SETTING OF THE LIMIT
CAMS, page 16.)
PRESETTING THE OBSTRUCTION DETECTION /
SENSITIVITY
The operator is equipped with an obstruction detection circuit which
will detect MOST obstructions in the gate's path. See Figure 18. The
sensitivity can be independently adjusted for OPEN and CLOSE with
the potentiometers on the controller board labeled, "OVERLOAD
FORCE". Turning a potentiometer clockwise decreases the sensitivity
and turning it counterclockwise increases the sensitivity.
The RS1000 is shipped from the factory with the potentiometers at their
most sensitive setting. Turn the potentiometer 1/4 turn clockwise to
prevent the overload circuit from tripping due to the gate's inherent
friction.
(See FINAL SETTING OF THE OBSTRUCTION DETECTION
SENSITIVITY, Page 16.)
TIMER TO CLOSE SETTING
The Timer to Close is controlled by the setting of the “AUTO CLOSE
TIMER” potentiometer on the control board, see Figure 19. When the
pot is adjusted fully counter-clockwise the Timer-To-Close is disabled.
Turning the pot approximately 1/4 turn clockwise will enable the Timer
To Close function with a delay of approximately 2 seconds between the
gate reaching the full open position and automatically closing. To
increase the time delay continue to turn the pot in the clockwise
direction to a maximum delay of 60 seconds (one minute).
IT IS HIGHLY RECOMMENDED THAT AUXILIARY
ENTRAPMENT PROTECTION DEVICES BE INSTALLED
WHENEVER THE TIMER TO CLOSE OPTION IS ENABLED.
PRE POWER-ON CHECKLIST
The following checklist should be used before turning on power to
the operator:
1. THE VOLTAGE TO POWER THE UNIT IS 115 VOLTS
AC;
2. The proper Left- or Right-hand Mode has been selected;
3. The Limit Cams have been mounted to the chain;
4. The Overload Sensitivity has been preset.
When the PRE POWER-ON CHECKLIST has been completed,
turn on the main power switch located in the 4 X 4 electrical box
under the control box/mechanical unit. Give the operator a push
button input command with a jumper wire attached to terminal #1
or #16, COMMON, on the terminal strip and touched briefly to
terminal #2, ALTERNATE to START the gate. If the gate was
fully open, as left in the previous step "MOUNTING THE LIMIT
CAMS" the gate will start in a close direction. If the gate was in
any other position but fully open, the gate will start in the open
direction.
Give the operator an ALTERNATE input command. The operator
should stop if OPENING; stop, pause and reverse if the gate were
moving in the CLOSE direction. See BASIC OPERATIONAL
GUIDE page 16.
