[. . . ] SAVE THESE INSTRUCTIONS This safety alert symbol means "Caution" - failure to comply with such an instruction involves risk of personal injury or damage to property. This gate drive mechanism is designed and tested to offer appropriately safe service provided it is installed and operated in strict accordance with the following safety rules. Incorrect installation and/or failure to comply with the following instructions may result in serious personal injury or proper ty damage. When using tools and small parts to install or carry out repair work on a gate exercise caution and do not wear rings, watches or loose clothing.

EN12453 specifies that a pair of photocells must be installed at a height of 200 mm and activated to "Close"; a second pair must be installed at a height of 200 mm and activated to "Open". A third pair of photocells can be optionally installed and activated to "Close" and "Open". The photocells consist of a transmitter and a receiver and must be opposite each other. The housing of the photocell (plastic) can be opened using a screwdriver. The photocell is mounted on the wall using small screws and wall plugs. The Chamberlain failsafe system (2-cable system) has small LEDs (light) that can be seen from the outside on both sides to indicate the status of the photocell. Two Chamberlain failsafe photocell models are available. The one model is ideal for walls lying opposite. The other model is ideal for the inside of the gate, because fittings are already available. Diagnosis at the Chamberlain failsafe photocell LED constant = OK LED flashes = photocell disables control board LED off = no current, incorrect connection or polarity Diagnosis on the control board LED off = OK LED on constantly = control board disables LED flashes = OK no photocell connected Cable cross-section: 0. Do not lay any 230 volt cables in parallel and do not lay any 2 cables in the same cable trunking. When connecting or removing photocell(s) - Switch off control board ( disconnect from current) - Slip jumper on designated pins - Dipswitch 5 to "ON" - Connect photocell(s) according illustration - Reconnect control board, wait short-time - Pull jumper, wait short-time Done!(The number of photocells connected are stored) Programming of relay photocells such as 263EML The control board must be disconnected from the mains for a few seconds. All terminals to which no photocell is connected must be bridged with COM. Note: Relay photocells are no longer permitted for new installations as per EN12978, because they cannot perform self-checks (failsafe). operation without photocells DANGER: Not permitted for normal operation. In this case contact strips must safeguard the gate. [. . . ] Disconnect controller from power supply, then alter Dip-switches. The gate opener doesn't respond at all, although the controller has been connected (LEDs are on). The gate opener doesn't respond at all; no LED is Possibly power failure. The gate opener stops suddenly and then restarts only after a lengthy pause. [. . . ]
