Understanding the LED Indicators on each CellMon
The red and green LEDs on the CellMon indicate the communication, bypass, and alarm states. This applies to each of the cellmon variants:
- BlockMon M8,
- BlockMon M14
When power is first applied, the green LED remains permanently “ON” (until the first message has been received). This allows initial confirmation of the correct power connection and network diagnostics. Once the first message has been received, the green LED will be OFF and then only indicates the message state with flashes. The green LED will flash in cell number sequence when being interrogated by PacMon/SiMon allowing diagnostics and status indication.
|Continually “ON”||Indicates that the power has been connected correctly (stays ON). It will turn OFF once the first message has been received. It is also ON while parameters are being set by the Batrium software.|
(0.5 sec rate)
|Status messages are being processed (from PacMon or SiMon). This flash passes through each CellMon in sequential cell # order.|
|Single flash||Flash when a valid configuration message has been interpreted.|
The red LED indicates the bypass state and also shows three alarm states.
(or flash intermittently)
|CellMon is bypassing current.
Note: May flash intermittently when close to bypass threshold voltage.
(0.5 sec rate)
|Over cell temperature or over bypass temperature.|
(0.1 sec rate)
|Over cell voltage or under cell voltage.|
|Single flash||Bad/corrupt message is received.|
