WatchMonCORE Relay-A

How can I program it? Which entry from the dropdown menu is the right one?

I want to disconnect the battery when the cell voltage of a single battery cell falls below a preset value and exceeds it.

Example:
2.5V relay should switch off when this value is undershot
3.65 relay should switch off when this value is exceeded

Where do I set 2.5V?
Where do I set 3.65V?

I want to set all the values ​​myself and not use any presets.

2.5V and 3.65V are just examples, my numbers will look different

Hi cit,

This is the option for high or low cell voltage:

(Cmu = Cell Monitoring Unit)

And the limits are configured in the Hardware > CellMon tab:

CV2 and CV11

Thank you for your help.

When the trip occurs, the contact is closed (current flows) suitable for MCCB Shut-Trip
For example ABB sace tmax
or
When the trip occurs, the contact is opened (current is interrupted) suitable for relays
For example EV200ADANA

Can I choose whether current flows or is interrupted?

Hi cit,

It sounds like you want the critical rules instead. Simply adjust the CellVolt Hi and CellVolt Lo on the Control > Critical tab to the thresholds you want.

From there, you can use the following options on the Expansion tab depending on your desired operation:

  1. Critical BattOk - This will be active (relay closed) whenever the battery is OK (not in critical)
  2. Critical Pulse Off (CB Trip) - Will be pulsed for a few seconds when the battery enters a critical state
  3. Critical Fault - This will be active (relay closed) whenever the battery is in critical state (and stays that way until it is OK again)
