Description

The 3-Phase Control Board is used to control automatic doors or gates that operate with 3-Phase. For example, heavy roller doors or sliding gates. The control card is available as a card only (3PH2) or with a weatherproof box (3PHE).

3PH2
The card only (3PH2) will require the user to connect their own push buttons and contactors.

3PHE
The 3PHE weatherproof box has built in push buttons and special high rated contactors for direct connection to the motor. The two built in push buttons each control up and down. There is also a separate key lock switch that is used to change from Auto, Manual and Off.

1. Auto operation disables the two push buttons on the weatherproof case. While the PCB push button (PB), PCB external down only push button (DO),  PCB photo cell (PC) and the remote control transmitter are enabled. The PCB connections are via a terminal block on the controller card Printed Circuit Board.
2. Manual operation enables the two push buttons on the case and the PCB Down Only push button. The PCB push button, PCB photo cell and the remote control transmitter are disabled.
3. Off turns the card off. Both Auto and manual features are disabled. 

The 3-Phase configuration can control a 3-Phase motor that uses a current rating up to 4.4 Amps. Higher current ratings are available on request.

There is a built-in PCB 4-way dipswitch that can be used to configure different functions. Below is a description of the different functions available.

1 2 3 4	Auto Closing enabled
	Auto Closing and Open Only enabled
	Auto Closing, Open Only enabled and Security Close enabled
	Auto Close, Open Only and Special Security Close
	Open Only enabled
	Open Only and Security Close enabled

Auto Closing is when the door automatically closes after a pre-set time. The pre-set time is user selectable between 3 to 60 seconds by a variable trimpot on the printed circuit board. The trimpot is labeled AC (Auto Closing). The photocell will reset the auto close timer. The door can still be closed with the PCB push button and the PCB down only push button. Auto close timer starts when door is in the up-limit switch (fully opened).

Open Only is where the door can be opened with the PCB push button, PCB down only push button, photocell and the remote control transmitter. When the door is opening or fully opened the PCB push button and remote control transmitter are disabled. Door can only close by the activation of PCB down only push button.

Security Closing
Enabled when switch 3 is 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 3 to 60 seconds can be set on the SLD board using the trimpot marked AC.

Special Security Close
Enabled when switch 4 is on. Same as Security Close except door does not reverse to open when Photo beam is broken. This is to prevent car-tailing on more secure sites

Technical & Installation Instruction
All power connected to the card should be disconnected before installation or adding extra options.

Options
• The PCB push button needs to be normally open contact (NO).
• The PCB down only push button needs to be normally open contact (NO).
• The PCB photocell needs to be a normally closed contact (NC).

For remote control operation an Elsema FMR-201, GLR2701SS or GLR43301SS receiver needs to be inserted into the control card. When the door is opening the remote controller can stop it anywhere but not when it's closing.
