5.1. CONNECTION TO ELECTRONIC CONTROL UNIT

Warning: Always turn off the electricity supply before carrying out any work on the electronic control unit (connections, programming, maintenance).

Observe points 10, 11, 12, 13 and 14 in the GENERAL SAFETY INSTRUCTIONS.

Since the system requires two different power supplies (230 and 400 Vac), install two differential magneto-thermal circuit breakers with adequate trip threshold up-line of the system.

Connect the earth cable to the connection on the base of the operator. See fig. 15.

The gearmotor is provided with a safety device (Fig.1 Ref.

7) operated by the relase system. While activated the safety device keeps the gearmotor from making any movement.

As shown in Fig. 3, prepare the conduits and make the electrical connections from the 844MPST 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.

a Low voltage terminal block J2 (Fig. 16) is used to

connect all accessories (see Table 4).

1. A/C Partial opening

This means any control device with a N.O. contact which causes partial opening of the gate when activated in E1, E2, A1, A2, S1 or S2 logics. In B and C logics it causes the gate to close. To install more than one partial opening control device, connect the N.O. contacts in parallel.

2. OPEN

This means any control device with a N.O. contact which causes the gate to open when activated. In automatic and semiautomatic logics it is active for both opening and closure. To install more than one opening control device, connect the N.O. contacts in parallel.

3. STOP

This means a control device with a N.C. contact which causes the gate status (opening-pause-closure) to be interrupted until the next impulse is sent. To install more than one stop device, connect the N.C. contacts in series to MS1 and MS2.

4. FSW SAFETIES

This means all devices (photocells, safety edges, magnetic loops) with a N.C. contact which stop the movement of the gate when an obstacle is present in the area protected by the safety devices. To install more than one safety device, connect the N.C. contacts in series.

N.B.: if safety devices are not connected, jumper terminals 4 and 5 on the electronic control unit.

W.LIGHT (terminals 6 - 8 - 9)

These are the 24 Vdc terminals to which the warning lamp must be connected. With jumper LK1 intact it is possible to power a 24V / 5W max. warning lamp between terminals 6 and 9. In case a potential free contact is needed between the terminal strips 8 and 9, the link LK1must be cut. (see Table 5).

WARNING: If the jumper LK1 is broken, the 24 Vac accessories power supply (terminals 6 and 8) is no longer available.

6. BEHAVIOUR OF SAFETY DEVICES

The safety devices operate during closure only. In "A1", "E1" and "S1" logics, interrupting the safety device contacts causes the gate to stop closing and start opening immediately. In "A2", "E2" and "S2" logics, interrupting the safety device contacts causes the gate to stop closing, then to start opening again when the safety devices are released. In "B" and "C" logics, interrupting the safety device contacts causes the gate to stop closing.

7. DIPSWITCH SETTINGS

To program automation operation, set the dipswitches as shown in the diagram below.
