N.B.:
Check that none of the rack elements come off the
pinion during the movement of the gate.
Important:
Do not weld the rack elements either to the
spacers or to each other (for steel rack only).
After installing the rack, lower the position of the gear motor
by adjusting the feet (Fig. 17) by about 1.5 mm to ensure
correct meshing with the pinion.

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).
Warning: When terminal board J2 is disconnected, high
voltage remains on the outputs of the capacitor, motor and
transformer power supplies.
Observe points 10, 11, 12, 13 and 14 in the GENERAL SAFETY
INSTRUCTIONS.
As shown in Fig. 2, prepare the conduits and make the
electrical connections from the 826 MPS electronic control
unit to the chosen accessories.

- Insert the elastic pin 7 in the shaft with the aid of a
hammer.
- Fit the chain pinion on the shaft by matching up the
pinion seats with the elastic pin and tighten up screw 4
and washers 5 and 6.
- Fit the idle transmission bracket on the gear motor flange,
removing the four upper bolts and replacing them with
the 5x12 hex bolts 1 and washers 2 in the kit as shown in
Fig. 20.
- Fit the chain as shown in Fig. 21 and mount the casing with
screws 1 and washers 3 (Fig. 20).

Check manually that the gate reaches the mechanical
travel limits correctly and that it does not encounter
friction during its travel.
Do not use grease or other lubricants between the pinion
and the rack.

MOUNTING CHAIN PINIONS
In versions for chain and idle transmission applications,
mount the Z16 or Z20 chain pinion. Proceed as follows:
4.5.1
MODEL 820 EMC - 860 MC - 860 EMC (figs. 18-19)
- Insert the elastic pin in the shaft with the aid of a hammer.
- Fit the chain pinion on the shaft by matching up the pinion
seats with the elastic pin and tighten up the screw with the
washers.
