If only one LED is lit, it is advisable to intervene to improve communication
as follows: move the TCW1/2 as close as possible to the IRW interface
antenna, or move the antenna to a higher position from the ground and/or
move it away from metal parts.
07. Checking the safety of the sensitive edge according to the level of pressure
(PSPE): press and release the sensitive edge, then make sure that the green
LED on the IRW interface changes from "flashing" to "steady".
08. On the interface, press and release the button: this operation deactivates
the "check operation" mode on the system.
09. Secure the leaf to the motor mechanically and command a manoeuvre.
Make sure the green LED on the interface starts to flash regularly and that
the door opens and closes correctly, without reversals of movement. The
green LED will only flash if a photo-optical edge is installed.
10. If necessary, perform the procedure on the unit that allows the unit to ac-
quire all the devices connected to its input and output terminals, to ensure
that the relays operate as expected (refer to the unit manual).
11. Check the following if photo-optical edges are installed:
• The time set with the jumpers (see Table 1) is activated the instant the unit
carries out the "Phototest" (the time starts from zero every time the "Pho-
totest" is carried out). As, once this time expires, the interface simulates the
intervention of the edge, and this may block the manoeuvre, if it is still in
place, in order for the automation to operate correctly, it is necessary for a
single manoeuvre or cycle of manoeuvres (automatic opening and closing)
to end before the expiry of the time set with the jumpers.
• Make sure that after commanding a manoeuvre, any intervention of the
edge causes the envisaged action from the unit, i.e.
- commanding an opening (or closing) manoeuvre;
- intervening on the sensitive edge as shown in point 7 and checking that
the behaviour of the automation is consistent with what is expected of the
unit for this circumstance (for example, it causes a reversal of the movement
of the closing manoeuvre).
Check the following for any type of edge installed:
12. If the potentially hazardous situations caused by the movement of the door
have been safeguarded by limiting the force of impact (type C, according
to EN 12445, in the part related to the pressure-sensitive device (PSPE)),
the interface and sensors must be checked by measuring the force with the
specific instrument along the route taken by the gate, in the specific points
envisaged in chapter 5 of the EN 12445 standard.
13. At the end of testing, secure each sensor permanently in its holder, as
shown in fig. 9.

Troubleshooting
7.1 - LED signals on a system with a resistive edge
7.1.1 - IRW interface signals
• The green LED flashes intermittently and continuously. If remains off, on the
other hand, if a "stand-by" function is active in the unit and disconnects power
to the interface when the automation is at a standstill.
• When the sensitive edge intervenes, the red LED lights up steadily and goes
off when the edge is disengaged.
• The IRW interface indicates "low battery" or "flat battery" as shown in the fol-
lowing table:
Battery status
Photo-optical edge
Low
1 beep every 8 seconds for the duration of the ma-
noeuvre.
Flat
2 beeps at the beginning of the manoeuvre only.
Battery status
8.2 kohm resistive edge
Low
1 beep every 8 seconds, until the batteries are re-
placed (note 1).
Flat
2 beeps + a pause, repeated until the batteries are
replaced (note 1) (note 2).
Note 1 – In the case of TCW2 sensors, the signal from the IRW interface stops
when the batteries are recharged by the solar cell.
Note 2 – The relevant signal is transmitted even if - for some reason - at least
one device does not reply.
7.1.2 - TCW1/2 sensor signals
• When the edge is not pressed:
– If the battery is almost flat, the red "A" LED flashes every ten seconds;
• When the edge is pressed:
– The "A" LED comes on and stays on until the edge is freed from the pres-
sure. In any case, it turns off after 1 minute. The light from the LED will be
green if the battery is charged, or red if the battery is low.
• When the battery is being charged:
– the red "B" LED (the one in the middle) flashes every 10 seconds.
