Nice IBW Instrucciones Y Advertencias Para La Instalación Y El Uso página 9

• To verify the state of efficiency of the sensitive edges
Press the sensitive edge and observe the LEDs on the IBW interface and on the
TCW1/2 sensor and refer to the table below:
IBW interface LED Meaning
flashing green: network active
red LED on: intervention of a safety device; e.g. edge pressed or opti-
cal beam interrupted a device does not respond
• "A" LED of the TCW1/2 sensor
Refer to section 7.2.2.
• "B" LED of the TCW1/2 sensor
In this case the "B" LEDs serve to indicate the quality of the radio signal according to
the table below:
B LED Meaning
off No signal or very weak signal
o Low signal
oo Medium signal
ooo High signal

This chapter explains all the possibilities for product customization, diagnostics and
troubleshooting.
A - What to do if... (Troubleshooting guide)
• The automation stops or always reverses the maneuver before finishing it.
Check proper radio reception of the TCW1/2 sensor by performing the "operation
check" procedure described in section 7.3.
If the BlueBUS network is the "mixed" type, make sure there is no optical interfer-
ence between the PHW wireless photocells and the hardwired ones; in this case,
solve the problem by inverting the TX and RX elements of the wireless photocells.
• The automation does not stop and does not reverse the maneuver when a
safety device intervenes.
– Make sure the control unit has acquired all the devices present in the IBW inter-
face: If the control unit has not acquired them, the IBW interface signals the state
with a periodic sound (beep) emitted during the maneuver or during the "operation
check" procedure. In these cases run the device search using the procedure in the
control unit instructions manual. The same operation can also be run with the
Oview programmer by sending the BlueBUS Search command.
– If the problem persists, make sure the various devices of the same type (e.g. all
the pairs of photocells) do not have the same jumper configuration.
• The flashing signaler functions only during the "operation check" proce-
dure.
Check proper connection of the device to the "Flash" terminal of the control unit
and make sure this output is configured with the "flashing" function. Moreover,
make sure the jumpers are positioned properly in the device.
B - Maintenance
Maintenance of system devices does not require any special measures. It is required
to run a test every six months; to check the condition of the devices (presence of
moisture, oxidation, etc.), externally clean them and inspect the system according to
the procedure described in the chapter titled "Inspection".
In the devices having a photovoltaic cell, perform more frequent checks of the clean-
liness of the surface occupied by the solar cell to guarantee maximum efficiency of
the recharging process. The system devices are designed to work for at least 10
years under normal conditions. After 10 years, it is advisable to intensify the frequen-
cy of the maintenance interventions.
