3.5.2) Second motor electrical connection;

If the installation envisages the use of 2 motors, a TN2010 and a
TN2020, make the electrical connection of the second motor as
described below.
1. Make the same connections for gearmotor TN2010 as those for
a single motor installation.
2. Between the control unit of the TN2010 and terminal board of the
TN2020 make the cable connections "second motor" and "sec-
ond motor courtesy light" as shown in (Figure 19), observing
polarity as specified.

4) Final checks and start-up

4.1) Power supply connection

!
TEN must be connected to the power supply by skilled and qualified personnel in possession of the requisites as spe-
cified and in full compliance with legislation, standards and regulations.
As soon as TEN is powered up, a number of checks are recommended:
1. Check that the BLUEBus led flashes quickly for a few seconds and then regularly with one flash per second (Figure 31).
2. If photocells are present, check that the leds on the latter also flash (both on TX and RX elements); the type of flash is not significant as
this depends on other factors.
3. Check that the device connected to the FLASH output is off
4. Ensure that the courtesy light is switched off.
If none of these conditions occur, disconnect the power supply immediately and check the electrical connections thoroughly.
Other information regarding fault-finding procedures are provided in the chapter "7.6 Troubleshooting"

4.2) Learning devices

After connecting to the power supply, the control unit must recognise the devices connect-
ed to the inputs BlueBUS and STOP. Before this phase, leds L1 and L2 flash to indicate that
the device self-learning process must be performed.
!
The device self-learning phase must be performed even if no device is con-
nected
1. Press and hold keys [▲] and [Set](Figure 20)
2. Release the keys when leds L1 and L2 start to flash quickly (after around 3s)
3. Wait a few seconds for the control unit to finish device self-learning.
At the end of the self-learning process, the STOP led must remain lit, while leds L1 and L2
turn off (where relevant leds L3 and L4 start flashing).
The phase of self-learning the devices connected can be repeated at any time also after
installation, such as in the case that a device is added.
