  • Page 11: Push To Open Installation

    Pull to Open Installation This installation method is the most common where the gate swings into the property/driveway. No matter which way you decide to install the actuator bracket and universal actuator bracket the pivot point below must be located in approximately this position for a pull to open installation. Gate Hinge Center (pivot point) Push to Open Installation This installation method is common where the driveway slopes up entering the property and gate must swing out to avoid interference. This type of installation places the actuator bracket and linear actuator into the drive area slightly. Another installation method would be to install as a Pull to Open and place linear actuator on outside of property. Push to open installation can be achieved by installing universal actuator bracket and actuator bracket as shown in figure below. Dimensions for this install method are 7” and 4” from hinge center. Universal actuator bracket hole pattern allows for the actuator bracket to be installed as shown in this location only. Establish enough offset in the rear actuator pivot point to allow the gate to close from the open position. IMPORTANT: If Installation is Push to Open, control switch #2 “operating direction reverse” must be turned “ON”.

  • Page 20: Sensitivity Adjustments And Entrapment Alarm

    Sentry Control Board Information The Sentry control board is capable of operating two gates. If your installation is a single gate you can operate the gate on the Gate 1 or Gate 2 connector. Set control switch “ON” for the connector being used. The Sentry gate opener was shipped with the receiver and entrapment siren already connected to the control board; these connections are plugs that can easily be disconnected. Sentry Control Board Sensitivity Adjustments and Entrapment Alarm Gate 1 and Gate 2 sensitivity adjustments are located on the left edge of the control board. Sensitivity is the primary safety control designed into the control board. The adjustment dials control the amount of force the gate can apply to an object before the gate will stop and reverse direction. If the gate senses an obstruction it will reverse direction. If it senses a second obstruction before reaching the fully open or closed position the gate will shut down. The entrapment alarm which is preinstalled in the control box will sound. Entrapment alarm will continue for 5 minutes then shut off. The entrapment alarm can be reset by pressing the “Reset” button on the control board. Sensitivity Adjustments If two obstructions were detected and control board has shut down, the “Reset” button will have to be pressed to re-activate the opener.

  • Page 21: Adjusting Gate 1 And Gate 2 Sensitivity

    Adjusting Gate 1 and Gate 2 Sensitivity Sensitivity factory setting is on position 5. This setting will work with most gates. Adjust so that when gate is stopped by an object, it stops and reverses direction. If gate stops and reverses for no obvious reason then increase force by slightly adjusting clockwise. If force is set too sensitive false sensing may be observed. IMPORTANT: If adjusting for a single gate, once adjustment for that gate is set, also set the other sensitivity adjustment to the same setting. Adjusting both Gate 1 and Gate 2 sensitivity adjustments to the same setting for a single gate installation will prevent the possibility of false trigger and gate reversal.

  • Page 30 Sentry Photo Eye (Send and receive) Part Number 550012 The photo eye is a secondary safety device. It produces a beam between the 2 units. When the beam is broken it will keep the gate from closing. It requires wires to be connected to both units (20 gauge) for operation. Typically a swing gate needs two sets of photo eyes for the best area protection (see figure below). One set of photo eyes pointing across the drive on the Transmitter Receiver outside of the hinge post (A). The second set mounted across the drive at the point where the gate is fully opened (B). The photo eye must be installed where the gate does not break the beam. The primary unit (Receiver) should be installed close to the control box. It requires 4 wires to be installed from the unit to the control box. The second unit (Transmitter) should be installed on the opposite side of the drive. It requires 2 wires to be installed from the unit to the control box. The two units must face each other to establish the beam (maximum distance 40 feet). Photo Eye Installation / Wiring Select a proper installation site, where the transmitter and the receiver can be along the same line and at the same height. Remove the cover from both units. Attach back plate to the installation site using mounting holes in back plate. If conduit is being used (recommended) knockouts are provided in the unit for 1/2”conduit fitting. Install wires into unit and strip 1/4” of insulation to prepare for wiring connections. Connect both conduits to a weather tight junction box.

Identify the gate that will not work and check the control switch for that gate and verify that it is turned “ON”. 3. Swap the Gate 1 and Gate 2 linear actuator connectors on the control board. If problem moves to other gate then the control board is bad. 4. If problem remains in the same gate then the problem is either a wire problem or linear actuator problem. Since it is a possible wire problem we need to check the following: A. Wire harness for cuts, nicks or bad splices if splice exist. B. If gate with problem is the gate located on the other side of drive from control box (Gate 2) the cable under the drive needs to be verified good. This is done by using a voltmeter and going to the junction box located below the Gate 2 linear actuator. Locate the red wire with white stripe and the black wire with white stripe and then operate the gate and check voltage on these two wires (expect 12 VDC). C. If voltage is present when gate should be operating then the problem is most likely the linear actuator. D. If voltage is not present when gate should be operating then move back to the control box side and check voltage on same two wires located in the wire compartment. E. If voltage is present on the control box side of drive then the cable in the ground must be damaged.

If installed in the closing push to open configuration verify switch is turned “ON”. 3. Gate is trying to close too far. Readjust close limit adjust for gate 1 or gate 2 to the correct stop position. 4. If time before auto opening cannot be adjusted and occurs in a couple of seconds after closing then the close limit adjustment of one or both gates is misadjusted. The feature that is causing the gate to open is the current sense circuit on the control board. The gate is trying to close farther than possible and it has traveled to the full extent of the linear actuator. Verify that linear actuator harness has no cuts or nicks. 5. Verify correct installation of the universal actuator bracket. Possible cause is incorrect installation of the gate bracket or linear actuator bracket. Verify and correct as required. 7.

Open the control box and press the transmitter button to operate the gate, listen closely for a clicking sound coming from the receiver. Click should be heard when the transmitter button is pressed if transmitter and receiver programming is correct and they are working correctly a sound should be heard. 3. If click was not heard verify that “Programming transmitter and Receiver” steps on page 22 have been completed. 4. If clicking sound was not heard, verify that transmitter battery is good, replace if necessary. 5. If click was not heard verify that transmitter dip switches were not changed after initial programming on page 22, if so then reprogram transmitter to receiver following steps on page 22 or set back to original setting recorded on page 22. 6. If click was not heard verify that receiver has power applied to it by pressing the P1 button on receiver and holding down until green light comes “ON” then release P1. If light comes “ON” then power to unit is correct. If light does not come “ON” verify that connector J1 is connected to control board correctly. If light does not come “ON” and power to receiver is good then receiver is possibly bad. 7. If clicking sound was heard then the problem might possibly be the control board. Verify control board is not the problem.

REVERSE BATTERY Check and correct any reverse battery. CONNECTION THERMAL RUNAWAY Old Battery - cells, inside battery, age differently. During CONDITION c harging, and over the course of many years of operation, OR, many battery discharges to levels beyond 100% discharged, this error may occur and the battery(s) may have to be replaced. CHARGE TIME MONITOR – Battery pack took too long to complete its charge. Possible 1 and 2 causes include a load (gate cycling repeatedly for a long period of time) during charging or the battery pack is too large (Many batteries connected in a parallel circuit). Apply the following formula to determine if the Timer may run out due to a large battery: Charge Time = Battery Capacity (AH) x 1.25 Calculated Charge Time must be less than approximately 108hrs.
