PRODUCT INSTALLATION

Preliminary checks – Application limits

Before proceeding with installation, verify the following.

• There are various versions of this product available, each designed to manage a specific motor torque. Each is designed to automate shutters/awnings/screens with specific dimensions and weight. Therefore, before proceeding with installation, refer to the "Guide to selection" in the Nice product catalogue (www.niceforyou.com) to check that the characteristics of this motor (motor tor que, rotation speed and operating time) are suitable for automating your shutter/awning/screen.
  
  Never install a motor with a greater motor torque than that required to move your shutter/awning/screen.
• Check the diameter of the winding roller. This must be chosen according to the motor torque, as follows:
  • for motors that are size "S" (Ø = 35 mm), the minimum inside diameter of the winding roller must be 40 mm;
  • for motors that are size "M" (Ø = 45 mm) and have a torque of up to 35 Nm (included), the minimum inside diameter of the winding roller must be 52 mm;
  • for motors that are size "M" (Ø = 45 mm) and have a torque of up to 35 Nm, the minimum inside diameter of the winding roller must be 60 mm;
  • for motors that are size "L" (Ø = 58 mm), the minimum inside diameter of the winding roller must be 70 mm.

Assembly and installation of the tubular motor

• Before starting, carefully read the warnings under section "SAFETY WARNINGS AND PRECAUTIONS".
• Incorrect installation could cause severe physical injury.

To assemble and install the motor, refer to fig. 7. Moreover, consult the Nice product catalogue or go to www.niceforyou.com to choose the crown of the limit switch (fig. 7-a/7-a1), the drag wheel (fig. 7-b/7-b1) and the motor fastening bracket (fig. 7-h).

ELECTRICAL CONNECTIONS

Installing safety devices in the electrical mains

In compliance with the electric installation rules, in the network that powers the motor, a short circuit protection device and a disconnection device from the mains electricity must be envisioned.
Attention! – The disconnection device must allow the complete disconnection of the power supply, in the conditions established by the over-voltage category III.
The disconnection device must be located in view of the automation and, if it is not visible, must envision a system that blocks any accidental or unauthorised re-connection of the power supply, in order to prevent any danger.
Note – The two devices are not present in the package.

Installing the wall-mounted pushbutton control panel

Recommendations:

• Position the push button control panel in view of the winding device but away from its moving parts.
• Position the push button control panel on the side of the winding device, where there is the electric cable coming from the tubular motor and the mains electricity power supply cable.
• Position the buttons at a height over 1.5 m from the floor.

Connecting the motor to a control pushbutton panel and the electrical mains

Attention!

• Incorrect connection can cause faults or dangerous situations, therefore scrupulously respect the instructions given in this paragraph. If in doubt, do not try to experiment but consult the relevant technical specifications which are also available on the web site www.niceforyou.com.
• The unit's power cable may not be replaced. If the cable is damaged, the device must be scrapped.

In electrical terms, the motor must be powered permanently, via a permanent connection electrical mai ns (consult data on the rating plate for motor). To connect the motor to a control pushbutton panel and electrical mains, refer to fig. 5. The connection cable wires are connected as follows:

Associating the Up and Down movements with the respective pushbuttons

On completion of connections, power up the motor and check whether the Up and Down movements are associated correctly with the relative control pushbuttons. If this is not the case, invert the connection between the Brown and Black wires.

LIMIT SWITCH ADJUSTMENT

Limit positions on opening and closing

During the up and down movements, the motor stops the shutter automatically when it reaches the limit switch positions (fig. 4): position "0" (shutter totally retracted) and position "1" (shutter totally extended). The factory settings of these positions are very approximate, and therefore follow the procedure below to adapt them to the specific dimensions of the roller shutter concerned.

Adjusting first limit position "0" and then limit position "1"

1. Move the shutter to position "1".
   > Align the adjustment screws with the respective limit positions:
2. Stand in front of the shutter and note the following:
   1. Stand in front of the roller and observe at which end the head of the motor protrudes: at the right end or left end of the roller?
   2. Stand in front of the roller and observe where the unrolled part of the rolling shutter is positioned: is in front of or behind the roller?
3. Then identify in Fig. 1 the diagram that corresponds to situations "A" and "B" observed in point 02. Very important – The identified diagram assigns a specific limit position to be set on each adjustment screw.
   > Setting limit position "0":
4. Activate the shutter so that it moves towards position "0" and wait for the motor to stop on activation of the limit switch pre-set with the factory settings.
   
   If the shutter moves beyond the point at which limit switch "0" is to be fixed, stop movement and then activate the shutter to move it back to the starting position; then turn the adjustment screw of limit position "0" through a few turns in the direction of the "–" sign and repeat the procedure from point 04.
5. Gradually turn the adjustment screw of limit position "0" in the direction of the "+" sign, to the required stop position "0".
   Note – on each turn of the screw, the motor moves to stop in the new position.
   > Setting limit position "1":
6. Turn the adjustment screw of limit position "1" through a few turns in the direction of the "–" sign.
7. Activate the shutter so that it moves towards position "1" and wait for the motor to stop on activation of the limit switch pre-set with the factory settings.
   
   If the shutter moves beyond the point at which limit switch "1" is to be fixed, stop movement and then activate the shutter to move it back to the starting position; then turn the adjustment screw of limit position "1" through a few turns in the direction of the "–" sign and repeat the procedure from point 07.
8. Gradually turn the adjustment screw of limit position "1" in the direction of the "+" sign, to the required stop position "1".
   Note – on each turn of the screw, the motor moves to stop in the new position.

Emergency manual manoeuvre (for model E MH/E LH only)
The model E MH/E LH is equipped with a mechanism fitted in the motor head (fig. 7-f) which enables the user to make an emergency manual manoeuvre by rotating the rod in one direction or the other. To avoid premature wear of the mechanism, it should be used exclusively in the event of an emergency, such as a power failure.

During this emergency manoeuvre, the shutter must NOT exceed the travel limits "0" and "1" set during product installation.

Troubleshooting Guide

What to do if...

The motor doesn't move even if powered the Ascent or Descent phase:

1. check whether a thermal cut-out has tripped: In this case wait for the motor to cool;
2. check that the mains power is ON and that it corresponds to the values on the motor dataplate.
3. check whether the two limit switches, due to incorrect settings, engage at the same time; in this case rotate the two adjustment screws through a few turns, in the direction of the "+" sign.
   After these checks, if the motor still does not move, contact a specialist technician or the Nice Assistance Service.
