General troubleshooting

In case of any system communication problems always check if all cables and power supplies are connected. Also check if the power sockets are not damaged.

S2 radio nodes

S2 radio nodes have a green LED on top which flashes in two different patterns. If the LED is not flashing then check the node power supply.

A radio node with a sensor shall turn LED on for 3 second and then off for 1 second. This sequence shall be constantly repeated.

The other pattern with 3 seconds off and 1 second on is used by the nodes without a sensor which are PC nodes and “link only” nodes.

If a radio node with a sensor has 3s off, 1 s on flash pattern, then it does not detect the sensor that is connected to it.

Correcting action: Check the sensor cable. Disconnect the sensor cable and connect it again a couple of times.

Check if the flash pattern becomes correct i.e. 3s on, 1 s off.

Update failure alarm codes

If the measurements from the sensor are not received by the system as expected then a “Value update failure” alarm is shown for the sensor. There can be 3 different error codes when a value update failure is detected. Double click on the alarm to see what the alarm code is.

Code 2604 “2604 The sensor could not be reached. Maybe the power to the node has been cut.”

The system has no contact with the sensor radio node. A most common reason for this is the sensor radio node has no power.

Correcting action: Check that the LED on top of the alarming sensor radio node is flashing 3s on 1 s off pattern as described in 22.2.1.

If the radio node LED is off or blinks 3s off 1s on indicating a sensor problem, disconnect both power and sensor cables and connect them again. Check if the pattern is 3s on 1 s off as it shall be.

Check that the power supply mains socket is OK connecting there some other equipment like a lamp.

If the radio node LED still does not flash, the node or its power supply may be faulty and must be replaced with a new one.

Final check: Log in to the system and check if the values are received.Sign the alarm.

Code 2503

“2503 The sensor is not detected. Maybe it has been disconnected from the node.”

The radio node doesn’t detect any sensor.

Correcting action: Disconnect the sensor cable and connect it again. If this does not help, replace the sensor.

Final check: Log in to the system and check if the values are received after the correction.Sign the alarm.

Code 2605

“2605 The application could not send a query to the sensor since the access media is not reachable.”

The Boomerang application can’t contact the radio PC node.

Correcting action: If the PC node is connected directly to the PC, check that its serial cable and power supply are connected. The correct LED pattern for PC node shall be 3s off, 1s on.

If the PC node serial port is connected via network using a LAN RS232 adapter, also check if the LAN adapter is powered up and has an active network connection. The LAN adapter has green and yellow LED in its network socket. Both these LEDs shall blink.

If no error is found, please contact your IT department for further investigation.

Final check: Log in to the system and check the values are received after the correction.Sign the alarm.

System Alarm codes

A1024

“A1024 The application have been unexpectedly terminated (and thereafter restarted automatically).”

The Boomerang service has been restarted. This may be caused by Windows update that require restart of the server/PC.

Control: If Boomerang is restarted and everything seems to work correctly, check that values are received and sign the alarm.

A4096

“A4096 The disk space is too low.”

Before making an automatic backup, Boomerang checks if there is enough disk space to do it. The system will raise this alarm if the space is smaller than the size of 2 Boomerang backups plus additional 100MB.

A32

“A32 There is no contact with the GSM Module.”

The Boomerang application has no contact with the GSM unit. If the GSM unit is connected directly to the PC, check its serial and power cable are connected and that the GSM power supply is working. If no error is found, please contact ICU Scandinavia for support.

If the GSM unit is connected through the network, also check that the LAN RS232 adapter has power and has an active network connection.

If no error is found, please contact your IT department for further investigation.
