User manual CHAMBERLAIN CB22 INSTALLATION

[. . . ] Disconnect electric power to the system before making repairs or removing covers. A disconnecting device must be provided in the permanently-wired installation to guarantee all-pole disconnection by means of a switch (at least 3mm contact gap) or by a separate fuse. Make sure that people who install, maintain or operate the gate drive follow these instructions. Keep these instructions in a safe place so that you can refer to them quickly when you need to. [. . . ] Depending on weight and function of the gate, it may continue to move on a bit further before stopping. The brake function is for the active braking of the gate in order to minimise this additional movement. PT2 (TRIMMING POTENTIOMETER 2): AUTOMATIC CLOSING (TIMER TO CLOSE) The waiting time for the gate for GATE OPEN can be defined. Impulse opens, the next one stops, the next one closes, the next one opens Impulse during closing opens Impulse during the rest closes the gate immediately Impulse opens for pedestrians, gate is moved open for 10 seconds (fixed), the next one closes, the next one re-opens for pedestrians Impulse opens, the next one closes, the next one opens Impulse during the rest closes the gate immediately Impulse opens for pedestrians, gate is moved open for 10 seconds (fixed) Impulse opens, the next one stops, the next one opens, the next one stops etc. Impulse during closing stops the gate, the next one opens No reaction if gate is closed Impulse during opening stops the gate, the next one closes Impulse during closing stops the gate, the next one closes, the next one stops, the next one closes etc. Impulse opens the gate completely, further impulses are ignored Impulse during the rest restarts the rest time Impulse during closing opens the gate No reaction during opening Impulse during the rest closes the gate immediately Impulse during closing fully opens the gate immediately Permanent signal required for opening, letting go stops Radio disabled, safety equipment disabled, limit switches are active Permanent signal required for closing, letting go stops Radio disabled, safety equipment disabled, limit switches are active Note: If important safety equipment ( photocell/contact strip) is damaged, constantly active (switching) or if programmed equipment is not connected, the control board operates without self-hold (hold to run). For any corrections, check the status LEDs or see functional description and "Frequently asked questions". PHOTOCELLS (OPTIONAL) The photocells are for safeguarding the gate and must be used. EN12453 specifies that a pair of photocells must be installed at a height of 200mm; a second pair must be installed in the same position at a height of 700mm. 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. 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 100263 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. The control board must be disconnected from the mains for a few seconds. [. . . ] the optimum location of the aerial is as high as possible in all cases. An appropriate aerial with installation kit can be obtained from Chamberlain as an accessory with the product ref. The control board does not work any more using the transmitter, only with the switch and even then only as long as a button is pressed and kept pressed. Open with push-button (1) or CLOSE with pushbutton (2) A safety photocell, a contact strip or the stop disables the control board 3. [. . . ]
