General safety precautions

Failure to respect the information given in this manual may cause personal injury or damage to the device. Keep these instructions for future reference

This installation manual is intended for qualified personnel only. Installation, electrical connections, and adjustments must be performed in accordance with Good Working Methods and in compliance with the present standards. Read the instructions carefully before installing the product. Incorrect installation could be dangerous. Before installing the product, make sure it is in perfect condition. Before installing the motorization device, make all the necessary structural modifications to create safety clearance and to guard or isolate all the crushing, shearing, trapping, and general hazardous areas. Make sure the
existing structure is up to standard in terms of strength and stability. The motorization device manufacturer is not responsible for failure to observe Good Working Methods when building the frames to be motorized, or for any deformations during use. The safety devices (photocells,  safety edges, emergency stops, etc.) must be installed taking into account the applicable laws and directives, Good Working Methods, installation premises, system operating logic, and the forces developed by the motorized gate. The safety devices must protect the crushing, shearing, trapping, and general hazardous areas of the motorized door. Display the signs required by law to identify hazardous areas. Each installation must bear a visible indication of the data identifying the motorized gate.

When requested, connect the motorized gate to an effective earthing system that complies with current safety standards. During installation, maintenance, and repair operations, cut off the power supply before opening the cover to access the electrical parts. The automation protection casing must be removed by qualified personnel only.

The manufacturer of the motorization device declines all responsibility if the component parts not compatible with a safe and correct operation are fitted. Only use original spare parts when repairing or replacing products. The installer must supply all information on the automatic, manual, and emergency operation of the motorized gate, and must provide the user with the operating in- instructions.

Installation

The declared operating and performance features can only be guaranteed with the use of Ditec accessories and safety devices. Unless otherwise specified, all measurements are expressed in mm.

6.1 Preliminary checks
Make sure the gate structure is sturdy and the hinges are lubricated and smooth. If possible, fit an opening and closing stop. Otherwise, use mechanical stops (built-in for opening stop, optional for closing stop) and/or the electromechanical limit switches (optional) if available. The mechanical construction elements must comply with the requisites of Standard EN12604.

The automation fastening point varies according to the space available and the gate to be automated. The installer must therefore choose the best solution to ensure that the system works correctly in each individual situation.

The installation measurements indicated in the table allow you to choose the values of [A] and [B] onthe basis of the required opening angle and in relation to the on-site spaces and overall dimensions. Increasing measurement [A], you reduce the opening approach speed. Reducing measurement [B], you increase the gate opening angle. Measurements [A] and [B] must, however, be compatible with the effective piston stroke.

6.2 Fastening the brackets

After selecting the most suitable point for fastening the front bracket [18] to the gate wing, to establish its height you must first size, position, and fasten the rear bracket [17]. If necessary, shorten the rear bracket [17] following the indications given in Tab. 6.1.
– Once you have fastened the rear bracket [17] following the measurements given on page 9, fasten the front bracket [18] to the gate.
– With the gate fully closed, position the front bracket [18], respecting the measurement (L). Make sure the front bracket [18] and rear bracket [17] are properly leveled, as shown in the figures below, then fasten the front bracket [18] to the gate.

6.3 Using the positioning template

During installation, the bracket positioning operation can be greatly simplified by using the positioning template (optional accessory) which allows you to
establish the correct position of the brackets and the distance between them. This avoids positioning errors and incorrect fixing hole alignment, thanks also to the built-in spirit level. The installation template is compatible with all the pistons of the PWR, Obbi, and Luxo ranges.

6.4 Installing the gearmotor

• Open the lock window [8], loosen the screw 3,9x22mm [9], and remove the rear cover [7]. Loosen the screw M4 x 8mm [10] and take out the front cover [11] as shown in the figure. Release the piston by inserting the key [23] in the relative lock [24] and turning it clockwise (see the User Instructions).

• Fasten the piston to the rear bracket [17] using the screw M8x45mm [19], the bush [20], and the washer Ø24mm [21], then tighten the self-locking nut M8 [22] as far as it will go.

• Open the gate wing manually and insert the front coupling pin [25] in the hole of the front fastening bracket [18]. Lock the pin in the
  bracket using the washer Ø30mm [26] and nut M16 [27] supplied. Before installing the piston, grease the rotation points.
  NB: pay special attention to the correct positioning of the washer on the brackets.

• After making the adjustments (par. 6.5 and 6.6), insert the front cover [11] on the drive screw and fix it in place using the screw [10].
  NB: make sure the drive screw [25] enters the head [28] of the cover [11] correctly (detail shown in figure a below).

6.5 Adjusting the mechanical end stop (standard on PWR50AC)
Bring the gate wing to its fully open position. Loosen the mechanical end stop with a 5mm Allen wrench, just enough so that it can slide along the drive screw. Move it up against the split nut and clamp them in place with a 5mm Allen wrench so fix the 3mm socket set screw.

6.6 Adjusting electromechanical limit switch (optional)
Bring the gate wing to its fully open or closed position. Loosen the limit switches with a Phillips screwdriver, just enough so that they can slide along the guide, then bring them above the split nut [14] until the sensor is activated. Fix them in place.

6.7 Reversible and irreversible piston
To make the piston reversible, insert pin [M].
NOTE: the operation must be carried out with the piston moving. Removing the pin [M], the piston becomes irreversible, and the release can only be made with the key (see USER MANUAL).

6.8 Electrical connections
To connect the automation to the control panel, proceed as follows:

• Remove the rear cover [7] as explained in paragraph 6.4.
• Fit the cable gland on the automation, inserting it in the relative threaded hole in the metal fusion (Fig. 6.2 and 6.3).
• Connect the various wires as shown in the electrical diagram in Fig. 6.4.
• Fasten the rear cover [7] to the gearmotor.
  The electrical connections and start-up of the PWR50AC gearmotors are explained in the installation manuals of the LOGICM / LCA80 control panels. To increase the protection of the motor cable, a corrugated flexible tube can be used.

Routine maintenance plan

Carry out the following operations and checks every 6 months or 36.000 cycles. Disconnect the 230V~ power supply and batteries (if present):
– Clean and lubricate the gate rotation pins, hinges and drive a screw with neutral grease.
– Check the state of wear of the brushes [12], and replace them if necessary.
– Check the resistance of the fixing points.
– Check the electrical connections are in good condition.
Reconnect the 230V~ power supply and batteries (if present):
– Check the power adjustment.
– Check all the commands and safety functions (photocells) are operating correctly.
– Check the release system is working correctly.
– If batteries are fitted, check they are working properly (in continuity) by disconnecting the power supply and performing a series of consecutive operations. At the end, reconnect the 230V~ power supply.

NB: for spare parts, refer to the spares price list
