• After having determined the position of the wall bracket, drill the holes and secure the bracket in place with dowels (not supplied).
• Insert the appropriate cotter 3 according to shaft cavity length.
• Secure the metal clamp 4 so as to prevent the risk of the cotter coming out of the shaft.

Chain link-up installation

5.1 Installation
ATTENTION! firmly tighten down all fastening screws.

• After having determined the position of the wall bracket, drill the holes and secure the bracket in place with dowels (not included) 1 .
• Fit the crown wheel onto the sectional door shaft and insert the appropriate cotter depending on shaft cavity length 2 . Fasten the metal clamp 3 so as to prevent the risk  of the cotter coming out of the shaft.
• Link up crown and pinion by means of the chain. Properly tauten the chain by acting on the wall anchoring brackets. Fix the bracket A to avoid that the shaft of the  sectional bends and to guarantee the correct tensioning of the chain.

Electrical connections

6.1 Power supply and limit switch connection with cable NRGCAB and Ditec control unit
It is recommended to use the cable type Ditec NRGCAB to connect Ditec control unit (EL400 or EL500E) to the NRG motor:
– Insert the supply terminal as shown in the 6A and 6B figures (fix it as arrows indicate).
– Insert the limit switch 6 pins clip (L) as figures 6C and 6D illustrate.
WARNING! Before the limit switch adjustment, on the EL500E central unit check the parameter 11 set up.

6.2 Power supply and limit switch connection without cable NRGCAB
If standard cable Ditech NRGCAB is NOT use it is recommended for:

• Motor power supply: remove the black power supply terminal and crimping the connections in compliance with Good Practice and current practices the legend of 6E figure.
• Limit switch connection: use a cable with AMP 0172168 clip on the both extremity and wired up as shown in figure 6F.

Be careful to connect the common and the two senses (down and up) in the shown positions.
WARNING! Before the limit switch adjustment, on the EL500E central unit check the parameter 11 set up.
In case the motor turns in the wrong direction, invert the two wires of the phase (L1, L2 and L3) on the F connector.

Limit switch setting

7.1 Absolute encoder limit switch setting – Ditec NRG100TXE, NRG100TRE AND
NRG140TXE
In Ditech NRG100TXE, NRG100TRE e NRG140TXE such tool is integrated in the limit switch that sends the commands to the external control. Through a telegram of pulses the tool determines and communicates to the electronic controls what the position of the sectional door is and consequently allows to perform the various assigned commands.
The data connection cable (with AMP connector) must be inserted in its place on the encoder L (Fig. 6C) and at the other end, in the control unit. Follow the control instructions and use the external electromechanical control panel in order to determine the up and down limit switch position and of any other auxiliary control.
This limit switch has no microswitches blocking the sectional door in case the limits are overcome. The external control panel will manage the security of the system.
7.2 Mechanical limit switch setting – Ditech NRG100TXF
The 6 cams send to a control unit the signals necessary to know what is the position of the sectional door and execute the various assigned commands accordingly.
The cams function is highlighted by their color (Fig. 7A): 2 green cams for the principal ones (up and down), 2 red cams for security, 2 additional yellow cams for the auxiliary controls.
Check that the motor direction of rotation corresponds to the complementary limit switch, otherwise invert one of the 3 phases of the 400 V 3~ supply.
For the limit switch adjustment use the Allen key 3mm and proceed as follows:

1. Close the door in down limit position, release the A screw of the Down cam, turn the cam till it reaches the microswitch pin, then tighten the A screw.
2. Tune the setting by the B screw of the Down cam till the microswitch is activated.
3. Open the door till the microswitch is free and then close it again.
4. Check and eventually tune the down limit through the B screw of the Down cam.
5. With the door in its closing position, set the safety down limit switch by releasing the A screw of the safety Down cam and turning it till it reaches the microswitch pin (but without activating it), then screw it again. The safety limit switch enables to stop the door, without any damage, in the case that the supply phases are reversed. In case it is activated, the control unit stops electrically the motor and no operation will be possible until the protection is removed.
6. After having activated the sectional door until the upper limit, adjust the Up cam and the safety Up cam in the same way you have done with the Down and security Down cams.

Routine maintenance plan

Perform the following operations and checks every 6 months according to intensity of use of the automation.
Disconnect the power supply 400 V 3~:

• Lubrication of mechanical parts must be performed with door down.
• Make sure that cable and spring breakage device is in perfect working order.
• Check lift-cable wear.
• Make sure that the cables run smoothly in the drums.
• Periodically grease the hinges, ball-bearings, wheel pins, and torsional springs.
• Check for any obstacles that may hinder the wheels from properly running in the guides.
• To check the correct balancing of the sectional automation.
• Make sure that the overhead sliding structure is firmly fastened to the ceiling and perfectly free from any defects, bending or buckling.
• Make sure that there are no loose bolts or screws.
• Absolutely avoid making any changes to the hoisting and/or sliding system.

Connect the power supply (400 V 3~) and check that:

• Limit switches are working properly;
• All control and safety functions are in good working order.

NOTA: only for Ditech NRG100TXE, NRG100TXF and NRG140TXE.
Before manually operate the sectional door, disconnect the main power supply. This prescription must be followed even if the manual operation is equipped with an electrical safety. Remember to re-connect the power supply after the emergency operation.
The door, when moved manually, must never overcome the up or down limit switches otherwise the door risks to be damaged and the limit overcoming activates the safety switches with the result that electrical operation will then be possible only after the intervention of a technician disabling the protection.
To manually activate the sectional door with the manual override with chain you must:

1. Pull the red knob and simultaneously the chain until the override engages the motor shaft and stops,  through the safety micro, the power supply.

2. Manually lift or lower the sectional door by means of the chain.
   WARNING: handle the chain uniformly without tugging.

3. When the manual override is accomplished, pull the green knob to turn the power supply on.
