AUTOMATED SYSTEM 746 & ELECTRONIC CONTROL UNIT 780D
These instructions apply to the following models:
746 ER Z16 - 746 ER Z20 - 746 ER CAT - 746 ER RF
The FAAC mod. 746 automated system for sliding gates is an electro-mechanical operator transmitting motion to the sliding leaf via a rack or chain pinion appropriately coupled to the gate.
The non-reversing system ensures the gate is mechanically locked when the motor is not operating and, therefore, no lock needs to be installed.
The gearmotor is equipped with a mechanical clutch which, combinedwithanelectronicdevice,offersthenecessaryadjustable anti-crushing safety and guarantees stopping or reversing the gate movement. A handy manual release makes it possible to move the gate in the event of a power cut or malfunction. The electronic control equipment is equipped with a gearmotor and is housed inside the operator.
The 746 automated system was designed and manufactured to control access of vehicles. Avoid any other use whatever.

1. DESCRIPTION AND TECHNICAL SPECIFICATIONS
1.1.MAXIMUM USE CURVE
The curve makes it possible to establish maximum work time (T) according to use frequency (F).
E.g.: The 746 gearmotor can operate non-stop at 70% use frequency.
To ensure efficient operation, operate in the work range below the curve.
Important:Thecurveis obtainedatatemperatureof24°C.Exposure to the direct sun rays can reduce use frequency down to 20%.

4. INSTALLATION OF THE AUTOMATED SYSTEM
4.1.PRELIMINARY CHECKS
To ensure safety and an efficiently operating automated system, make sure the following conditions are observed:
•Thegatestructuremustbesuitableforautomation.Thefollowing arenecessaryinparticular:wheeldiametermustbeinproportion totheweightofthegatetobeautomated,anupperguidemust be provided, plus mechanical stop limits to prevent the gate derailing.
•The soil must permit sufficient stability for the foundation plinth.
•Theremustbenopipesorelectriccablesintheplinthexcavation area.
•If the gearmotor is exposed to passing vehicles, install, if possible, adequate means of protection against accidental impact.
•Check if an efficient earthing is available for connection to the gearmotor.
4.2. MASONRY FOR FOUNDATION PLATE
1)Assemble the foundation plate as shown in figure 4.
2)The foundation plate must be located as shown in figure 5 (right closing) or figure 6 (left closing) to ensure the rack and pinion mesh correctly.
3)Prepare a foundation plinth as shown in fig.7 and wall the foundation plate, supplying one or more sheaths for routing electric cables. Using a spirit level, check if the plate is perfectly level. Wait for the cement to set.
4)Lay the electric cables for connection to the accessories and power supply as shown in figure 3.
To make the connections efficiently, allow the cables to project by about 40 cm from the hole (Figs.5-6 ref. ) of the foundation plate.

4.3. MECHANICALINSTALLATION
1)Assemble the securing corners and anti-vibration spacers on the operator as shown in Fig. 8.
2)Open the cover, unscrewing the securing screws.
3)Place the operator on the plate, using the supplied washers and nuts as shown in Fig. 9.
During this operation, route the cables through the duct inside the lower half-casing of the operator (Fig.10 - Ref. A).
To access the electronic equipment, route the cables through the appropriate hole, using the supplied rubber cable-clamp. Make absolutely sure to unsheathe all the cables so that the clamp holds single cables only (Fig.10 - Ref. B).
20
5)Secure the gearmotor to the foundation plate, tightening the nuts as in Fig.12.
6)Prepare the operator for manual operating mode as described in chapter 8.

4.4.INSTALLING THE RACK
4.4.1.STEEL RACK TO WELD (Fig.13)
1)Placethethreethreadedpawlsonthe rack element, positioning them at the top of the slot. In this way, the slot play
will enable any adjustments to be made.
2) Manually take the leaf into its closing position.
3) Lay the first piece of rack level on the pinion and weld the threaded pawl on the gate as shown in figure15.
4)Move the gate manually, checking if the rack is resting on the pinion, and weld the second and third pawl.
5)Bring another rack element near to the previous one, using a piece of rack (as shown in figure 16) to synchronise the teeth of the two elements.
6)Move the gate manually and weld the three threaded pawls, thus proceeding until the gate is fully covered.
4.4.2.STEEL RACK TO SCREW (Fig. 14)
1)Manually take the leaf into its closing position.
2)Lay the first piece of rack level on the pinion and place the spacer between the rack and the gate,
positioning it at the top of the slot. 3) Mark the drilling point on the gate.
Drill a Ø 6,5 mm hole and apply thread with a Ø 8 mm male tap. Screw the bolt.
4) Move the gate manually, checking if the rack is resting on the pinion, and repeat the operations at point 3.
5)Bring another rack element near to the previous one, using a piece of rack (as shown in figure 16) to synchronise the teeth of the two elements.
6)Move the gate manually and carry out the securing operations as for the first element, thus proceeding until the gate is fully covered.
4.4.3.NYLON RACK TO SCREW (Fig.14bis)
1)Manually take the leaf into its
closing position.
2) Lay the first piece of the rack level on the pinion and mark the drilling point on the gate; drill Ø 4 mm and screw the self-tapping screw 6 x 20 mm to the relevant reinforcing plate.
3) Move the gate manually, checking if the rack is resting on the pinion, and repeat the operations at point 2.
4)Bring another rack element near to the previous one, using a piece of rack (as shown in figure 16) to synchronise the teeth of the two elements.
5)Move the gate manually and carry out the securing operations as for the first element, thus proceeding until the gate is fully covered.

Notes on rack installation
•Make sure that, during the gate travel, all the rack elements do not exit the pinion.
•Do not, on any account, weld the rack elements either to the spacers or to each other.
•When the rack has been installed, to ensure it meshes correctly with the pinion, we advise
you to lower the gearmotor position |
|
|
by about 1.5 mm (Fig.17). |
|
|
• Manually check if the gate |
|
|
habitually reaches the mechanical |
|
|
stop limits and make sure there is no |
|
|
friction during gate travel. |
|
|
• Do not use grease or other lubricants |

4.5.INSTALLATION OF CHAIN PINIONS
In the versions for applications with chain and idle transmissions, a Z16 or Z20 chain pinion must be installed. Proceed as follows:
4.5.1.MOD. 746 ER CAT (Figs. 18 - 19)
1)Insert the spring pin on the shaft, using a hammer.
2)Fit the chain pinion on the shaft, making the pinion seats coincide with the spring pin and tighten the screw with the appropriate washers.
Fig. 19
4.5.2.MOD. 746 ER RF (Figs. 20 - 21)
1)Insert the spring pin on the shaft, using a hammer.
2)Fit the idle transmissions bracket on the gearmotor flange, using the four screws (M5 x 12) and the appropriate washers , in the kit as shown in Fig. 20.
3)Fit the chain pinion on the shaft, making the pinion seats coincide with the spring pin and tighten the screw and the appropriate washers and .
4)Pass the chain as shown in Fig. 21 ref. A and install the housing with screw and washer as in Fig. 20.
5)In case of operators with MLS limit switches, arrange the supports for the positioning of the magnets supplied while observing the dimensions given in fig. 21 ref. B.
