Description

The GATCOS comes in four versions, GATCO12S (12V single motor), GATCO24S (24V single motor), GATCO12D (12V double motors), GATCO24D (24V double motors). It is designed to control automatic doors or gates that use DC motors and limit switches.

The GATCOS has a built-in push button input, photocell control, lock control and 3-minute light timer. Optional wireless operation is available with a plug in receiver.

The GATCOS is also available with a C220 plastic case. These are called the GATCO12SE (12V Single Motor), GATCO24SE (24V Single Motor), GATCO12DE (12V Double Motor), GATCO24DE (24V Double Motor).

Features include Auto Closing, Open Only and Security Closing. These features are user selectable using the on board 2-way dip switch. See table below:

Auto Closing
Enabled when switch 1 is on. The Auto Close timer can be adjusted from 6 to approximately 60 seconds by the on board trimpot called AC. Auto Close timer starts when the door/gate is opened and stopped. Input from the Photo Cell will hold-off the closing cycle, i.e. auto close timer is reset on a photocell input.

Open Only
Enabled when switch 2 is on. This feature enables the user to open the door/gate but when the door/gate is opening the remote control is disabled and the door will fully open. Door closes when auto close timer expires.

Security Closing
Enabled when switch 1 and 2 are on. The door/gate immediately closes after the photo beam is broken and the vehicle moves away from the photo beam, even if the door/gate is not fully open.

If the door/gate is opening and no vehicle passes through the door/gate then Auto Close will close the door/gate. An Auto Close time of 6 to 60 seconds can be set on the GATCOS board using the trimpot marked AC.

Other Features
M1 Overload Trimpot
The trimpot labeled M1 sets the amount of overload. Turn clockwise for more overload power, anti-clockwise is less overload power. M1 is for motor 1.

Overload
If an overload condition occurs on opening the door/gate will stop. If the overload occurs on the closing direction the door/gate will stop and then open.

AC Trimpot
This trimpot sets the auto close time. A time between 6 to 60 seconds can be selected.

Red LED
The Red LED labeled PC indicates that the photocell beam is broken.

Replaceable Fuse
Replaceable 240VAC 10 Amp fuse.

Safety Feature
The GATCOS has a built-in switch off protection. The motor will switch-off after 60 seconds of continuous running. This is called the maximum run timer.

Installation Instructions

Important: Before operating the GATCOS for the first time, check that the door/gate is in the half way position. Then press the push button. The door/gate must move in the opening direction . If the door closes, reverse motor wires at the terminal block.

Care should be taken not to cross printed circuit board with 240V wires over or under the board. This would induce spikes onto the sensitive circuitry of the printed circuit board.

Wiring Connections

Antenna
The antenna connection is used to connect an antenna for the plug in FMR-201, GLR2701SS or GLR43301SS. The antenna can be a 50 ohms Antenna or piece of approximately 1 metre of wire.

Shield
This is used if a coaxial cable is used with the antenna. The shield of the coaxial cable should be connected to this terminal.

Transformer
The transformer and rectifier used to power the GATCO board should be large enough to power the motors (check motor rating). If an electronic lock is used a larger transformer and rectifier should be used to power the motor and lock. Note some locks draw as much as 6 amps.

Power + -
Connect 12 Volt DC (24 VDC for GATCO24S) to the terminal block marked - +. Power supply should be large enough to supply current to the motor and lock.

Motor
Motor should be rated for 12 Volt DC for GATCO12S. For a 24 Volt DC motor use GATCO24S.

Push Button Input
Push button is a normally open contact. When pressed it will start the opening or closing cycle. This push button should be waterproof for internal and external use. Waterproofing will prevent false activations, which normally occurs due to moisture inside the button. Door/gate can be held open permanently when the push button is pressed continuously.

LOCK Output
This terminal block outputs a short pulse of approximately 3 seconds on opening and closing cycle. This is used for a standard 12V lock.

To use the 3-second pulse feature, a suitable transformer needs to be connected to the GATCOS. This transformer will supply the current that will operate the lock. Recommend transformer size is 60VA to 100VA.

Light Output
This terminal block outputs 12 volt DC (24 Volt DC for GATCO24S) each time the push button is pressed. This output is on for 3 minutes and can be used to operate an external light.

Photo Cell Input
Photo Cell input is normally closed contact. The photocell is used as a safety feature. If the door/gate is closing and the photo beam is broken, door/gate will stop instantly and then open fully again. Should an object be blocking the door/gate (i.e. photo cell is broken), closing cycle or auto closing is disabled.

If no photocell is used a link must be connected to the PC input terminal.

Remote Control
Remote control is achieved by inserting Elsema’s FMR-201, GLR2701SS or GLR43301SS receiver. Power to the GATCO printed circuit board should be switched off during the installation of a receiver. The transmitter can be an FMT-301, GLT2701 or GLT43301 respectively.

Limit Switch Connection

To  operate a single motor from a double motor controller card.
The GATCO12D AND GATCO24D control boards can be operated with a single motor only. Simply place 2 links at the specified positions as illustrated (circled in white).
Please ensure motor is connected to M1 only.

To operate double motors with no startup delays between motor 1 and motor 2.
Simply place 2 links at the specified positions as illustrated (circled in white).This will remove the startup delay between both motors.
Both Motors connected. Connect Motor 1 to M1 and Motor 2 to M2.
