Description

Automatic Doors in recent years have become part of our lives, we want shopping malls, restaurants, factories and even our homes to have Automatic Door Controllers installed.

The ADC302-12 is used for 12VDC motors while the ADC302-24 is used for 24VDC motors.

The ADC302 have an adjustable Auto-Close time of 2-60 seconds.

The overload trigger level has a separate trimpot setting for opening (up) and closing (down), this enables the user to accurately set the overload sensitivity in each direction.

Technical & Installation Instruction

1. Power Supply: Use suitable 12 (ADC202-12) / 24 (ADC202-24) Volt 5 Amps transformer.

2. We advise to install a 2 Amps fuse on the 240VAC side of the transformer.

3. "Open Relay" must open door, if wrong, reverse two wires to the motor.

4. Turning Clockwise on the overload trimpot will enable more motor power before tripping.

5. Up and Down limit switches are Normally Closed Contact (NC).

6. On-board push button may be used with a suitable linkage to any external button.

7. Photo Cell contact must be "normally closed" for operation.

8. Antenna wire to be approximately 1-2 metres wire, keep clear of other wires or metal frames.

9. Light relay. Has auxiliary N/O contact, operational together with 3-minute courtesy light.

10. Size of printed circuit board is: 115 X 105 X 40mm.

11. Mounting Hole spacing is: 105 X 95mm. Use 1/8" or 3mm screws.

12. If Auto close switch is on, door will close after being opened at an adjustable time: 2-60 seconds
