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 23. 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).

AUTO RE-CLOSE (TIMER-TO-CLOSE FUNCTION)

Switch S2 controls the Auto-Re-close function. If the Timer To Close function is enabled (see above), setting Switch S2 to the ON position will activate the Auto-Re-close feature on the motor control board. When the auto-re-close is activated, the gate will re-close after stopping and backing-off from a non-contact sensor input if the close movement was initiated by the Timer-To-Close function on the control board. The gate will not re-close if the sensor input was received from a contact sensor or if the inherent overload sensor was activated.

MASTER/SLAVE CONFIGURATION

Switch S3 controls the Master/Slave Terminals (#s 14 & 15) configuration setting. The setting is used when two control boards (boxes) are used in conjunction with two mechanical units.

With Switch S3 in the ON position terminals 6 & 7 (OPEN & CLOSE) are in the Slave mode and could be coupled to and would be controlled by a Master control board (box). With Switch S3 in the OFF position terminals 14 & 15 are in the Master (output) mode and could be coupled to and would control a Slave control board (box).

APPLYING POWER TO THE GS4000

PRE-POWER CHECK LIST

Before applying power to the GS4000 for the first time, go through the following check list to ensure that all is in order for the application of power.

1.Check that the GS4000 power switch is off.

2.Check that the breaker at the power panel is on.

3.With a voltmeter on the proper scale, check that the line voltage at terminals L1 and L2 on the GS4000 control board is the voltage that is expected. Connection of a 115 VAC GS4000 to an unexpected 230 VAC line is a common occurrence. This will cause readily identifiable board failure that WILL NOT BE COVERED UNDER WARRANTY.

4.Manually move the gate to the center of the gate opening.

5.Make sure the Torque Limiter is properly adjusted to slip under a load when a moderate amount of force is applied to the gate in the center of its travel. If the adjustment is too loose, the overload sensitivity will not function properly and the Torque Limiter may slip when the gate is under a wind loading. Start by tightening the large nut on the Torque Limiter to 35 ft-lbs./in. To fine tune, increase or decrease this by approximately 5 ft-lbs./in. increments. When a satisfactory setting is found, tighten the set screw in the side of the large nut.

6.Set all the Switch selectable options switches ON for the test mode.

7.Make sure that the overload sensitivity potentiometers (Open and Close) are set to their preliminary start up position.

8.Temporarily remove the white high voltage connector from the control board.

CHECKING THE INDICATOR LIGHTS

There are 16 indicator lights on the control board of the GS4000. See Figure 24. These lights are used to verify proper operation of the GS4000.

TURN ON THE MAIN POWER SWITCH TO THE GS4000.

•Note that the “POWER” lamp is lighted. This indicates that power is applied to the control board and the power supply is functioning

1.Connect one end of a short piece of wire (not supplied) to terminal #16 (COMMON).

2.With the other end of this wire, (make sure that this loose end is free of insulation), touch the following terminals and observe the noted response of the lamps.
