The polling interval can be set between 1 hour and 48 hours. It is advisable to not set shorter
polling interval than the default 24 hours in a live installation.
Heartbeat interval
The indicator sends a heartbeat message to the recipient(s) in a configurable interval. The
range is 1 hour to 720hours. Default setting is 144 hours.
The heartbeat message contains the current status of the device as well as the GSM signal
level.
When the receiver system is NetTroll, NetTroll will set up an alarm in the central unit if two
consecutive heartbeat messages are missing from the same unit. (Missing Heartbeat Alarm).
Other GSM features
The LineTroll R400D has several configuration settings for how the GSM modem should
operate.
Setting alarm/heartbeat up-time
Defines the period the GSM modem is connected to the GSM network after having
sent an alarm or a heartbeat message.
Setting polling up-time
Defines the period the GSM modem is connected to the GSM network after having
done the regular polling sequence and checked the GSM network for messages
addressed to the device.
Boot message
The boot message is sent when the indicator is powered up or it the internal
watchdog function have reset the software. If this message is enabled, it will also be
sent when the device is reset when the lens is twisted to RESET position.
Sending boot message can be switched OFF.
Loss of Voltage message
When this message is activated, the unit will
send a “Loss of Voltage” message to the
recipients. This feature is default switched off.
Please note the electrical field the indicator see may vary upon several factors such as
rain, snow and external influencing sources so it is recommended to keep this feature
off to avoid unnecessary messages.
When the indicator detects a fault, and the circuit breaker has tripped, the Loss of
Voltage bit will be sent anyway to indicate the status of the feeder even if the Loss of
voltage message is switched off.
When the feeder is restored and the line energized again, the Loss of Voltage bit will
also be reset if the line is energized.
