Allstar Products Group HDSWG 1000 owner manual Accessory Equipment HOOK-UP

The Limit Switch contacts of the two Bi-Parting units need to be wired in series. Both limit switch contacts must be closed before a connection is made to the limit switch input at the Control Box to stop the motors at the Open or Closed position.

The operation of the Bi-Parting installation is as follows: After receipt of a command to open, both units will begin to open together. The first gate to reach its open position will be stopped by the mechanical stop. Its motor will continue to run. The Torque Limiter will be adjusted to slip when the stop is encountered with the motor still running. The limit switch contact on this first unit is adjusted to close at this position. The second gate has not reached its fully open position. Its limit switch will be still open and no command will be given to the limit switch input at the terminal board until the gate has reached the maximum open position and the open limit contact is closed. Now, a contact will be made to the limit switch input at the terminal board through both limit switch contacts. Both motors will be turned off.

A wiring schematic of the Bi-Parting installation is shown in Figure 13. It is important this schematic be followed closely and that the color codes at the MECHANICAL UNITS and the CONTROL BOX be followed exactly. Most of the difficulties encountered with Bi-Parting installations are due to the wiring instructions not being followed.

ACCESSORY EQUIPMENT HOOK-UP

All accessory equipment is connected to the 13 terminal barrier strip located at the bottom of the HDSWG 1000 Control Box (Backplane). To expose this terminal strip and the Backplane, remove the cover on the Control Box.

There are 7 command inputs (#6 through #12) available to the installer on the HDSWG 1000 in a addition to 2 commons. To trigger any of these inputs, a switch or relay closure to the common terminal for a duration longer than 100 milliseconds and of a resistance of less than 100 ohms is necessary. Three of the inputs, HOLD OPEN, REVERSING & STOP, can be continuous commands as noted below. Labels on the Backplane

identify the function of each of the terminals on the barrier strip. See the INPUT COMMANDS Reference Chart on page 18 related to each terminal number on the barrier strip for an explanation of each of the inputs.

The HDSWG 1000 has an auxiliary transformer mounted in the Control Box to power accessory equipment. This is a Class II transformer and is equipped with an internal fusible link. If this link is "blown" the transformer must be replaced. The transformer is powered at all times that the HDSWG 1000 main power switch is ON. It is not fused by any of the fuses on the Backplane. The maximum power that can be supplied by this Auxiliary transformer is 20VA or about 1 Ampere at 24VAC. This is usually sufficient to supply most accessory equipment such as a radio receiver, loop detector or card or key pads.

IF THE AUXILIARY TRANSFORMER IS USED TO POWER A RADIO RECEIVER, NO OTHER EQUIPMENT MAY BE CONNECTED TO THE AUXILIARY TRANSFORMER. When a radio receiver is connected to the transformer for power, one end of the receiver relay must be connected to the common terminal on the barrier strip. This will effectively ground one side of the auxiliary transformer even if it is a "4 wire" receiver---in most cases. Many other auxiliary devices, such as card readers and key pads, (using bridge rectifiers) require that both sides of the transformer supplying power be "floating" and not grounded. FAILURE TO OBSERVE THIS RESTRICTION WILL DAMAGE THE ADDED DEVICE.

WIRING RADIO RECEIVERS TO THE TERMINAL STRIP

Radio Receivers may be either 3 wire (terminal) or 4 wire units.

THE 4 WIRE VERSION OF THE RECEIVER IS PREFERRED SINCE NO ADDITIONAL CONNECTIONS TO THE RECEIVER WILL BE REQUIRED.
