5.1. CONNECTION TO ELECTRONIC CONTROL UNIT

ÜAlways disconnect the electrical power supply before carrying

out any operations on the control unit (connections, programming, maintenance). Warning: On disconnecting connector J6, high voltages may be present on the capacitor output.

Observe points 10, 11, 12, 13 and 14 in the GENERAL SAFETY INSTRUCTIONS. As shown in Fig. 3, lay the conduits and make the electrical

connections from the 844 MPS electronic control unit to the chosen accessories. Always route the power supply cables separately from the control and safety cables (keyswitch, receiver, photocells, etc.). Use separate conduits to avoid any interference.

5.2. DESCRIPTION

5.2.1. CONNECTOR J1

The connector J1 is used for the quick connection of MINIDEC,DECODER, RP RECEIVER boards (Figs. 25,26,27). Accessory boards are to be inserted with their component sides facing the inside of the 844MPS electronic control unit. Always disconnect the power supply before inserting or removing accessory boards.

5.2.2. TERMINAL BLOCK J2 (low voltage)

1& 5

=Common/Negative of accessory power supply (-)

2 = OPEN control device (N.O.)

Any control device (pushbutton, detector,..) which, on closing the contact, relays an open and/or close impulse to the gate. To install more than one Open control device, connect the N.O. contacts in parallel.

3 = STOP control device (N.C.)

Any control device (e.g. pushbutton) which, on opening a contact, stops the movement of the gate. T o install more than one Stop control de vice, connect the N.C. contacts in series. ÜIf no Stop control devices are to be connected, place a jumper across the input and the common terminal (terminal 1 or 5).

4 = FSW closure safety device (N.C.)

Any control device (photocells, safety edges, magnetic loops) with an N.C. contact which interrupts the movement of the gate when an obstacle is detected within the protected area. The task of the closure safety device is to safeguard the area occupied by the gate during the closing movement. The intervention of safety devices during gate closure causes the direction of gate movement to be reversed. These devices do not intervene during gate opening movements. If a closure safety device is tripped when the gate is open or during a pause time, they will prevent gate closure. To install more than one safety device, connect the N.C. contacts in series. ÜIf no closure safety devices are to be installed, place a jumper across this input and the commmon terminal (terminal 1or5).

8 = 24V~ accessories power supply

The maximum load of the accessories is 500mA. To calculate power draw, refer to the instructions for the individual accessories. ÜIf the jumper LK1 is broken, the 24V~ accessories power supply is no longer available (Fig.28).

7 = 24Vdc

accessories power supply positive (+)

The maximum load of the accessories is 500mA. To calculate power draw, refer to the instructions for the individual accessories.

9 = Warning Light output

For information regarding operation of the warning light, refer to the section on dipswitch programming.

Jumper LK1 allows you to free the warning light contact (Fig.28).
