Installation manual
Attention:
Ensure that only the system devices are connected to the loop.
10.3
Fault on devices connected to the RS485 BUS
If the display shows “
Repeater Lost
”, “
Power Stat. Lost
”, “
Ext. Stat. Lost
” , the panel is
unable to find any devices connected to the BUS.
• Check that the device addresses have been assigned correctly (refer to paragraph
7.10.1 Setting the
devices connected to the RS485 BUS
).
• Check the integrity of the wiring and the connection polarity.
• Check that the EOL jumper is in the EOL position only on the last repeater or power station connected to
the BUS.
• Using a multimeter or similar tool for the electrical measurements:
- Measure the voltage across the +24 V and GND terminals of the RS485 BUS. If the voltage is below 20
V, the resettable protection fuse is open, therefore, the current draw of the devices connected to the
BUS is excessive.
- Disconnect the devices connected to the BUS one at a time until you find the cause.
10.4
Battery Fault
If the “
Battery lost
” message is shown, the batteries are either disconnected or have failed the battery
efficiently test.
Allow them to recharge for several hours. If the trouble persists, disconnect the batteries from the panel
and, using a multimeter or similar tool, measure them separately.
• If only one of the batteries is below 12.5 V: replace the battery concerned and allow it to recharge for
several hours until fully charged.
• If both batteries are below 12.5 V .13 V: replace both batteries and allow them to recharge for several
hours until fully charged.
• If the battery is equipped with a thermal probe, check that the voltage value corresponds to the value
calculated with the assistance of the graph (paragraph
7.16.4 Connecting the batteries
). If there is a
discrepancy in the value, correct it by means of the trimmer on the power supply module.
If the “
Low Battery
” message is shown, the primary power source (230 Vac mains power) is
disconnected. This condition must be cleared before the batteries get too low and are unable to power to
the system.
10.5
SmartLoopNET Fault
10.5.1 Error in the token ring network configuration
Figure 31 - Access Denied message
This message appears when:
• The SmartLoop/NET board is not operating properly.
Check that the board is inserted properly.
Relaunch the auto-configuration phase.
Ensure that the blue LED (paragraph
5.1 - [E]
) remains On during this phase, and that the activity LEDs
of nodes A and B (paragraph
5.1 - [F]
and paragraph
5.1 - [G]
) flicker to indicate communication
attempts on both sections.
If all the LEDs are Off, the board may be damaged and it may be necessary to replace it.
