Button function
The new Solar MD Multipurpose button has an extended functionality in combination with the BMS-EM v10.01.
The Multipurpose Button can be used to directly execute 6 predefined functions and a shutdown instruction. In
combination with the 6 Indication LEDs on BMS-EM v10.01, the user can choose between each function by
holding the button until the LEDs count match the number of the function. By releasing the button while moving
through the functions, LEDs will start blinking and wait for the user to press the button again within 3 seconds.
The predefined functions are:
1. Reserved
2. Change indication LED function between: Show Capacity, Show Current, and
Off
3. Reserved
4. Wake up if Sleep mode is active.
5. Activate Override Off state for 60sec
6. Activate Override On state for 60sec
If the button is held continuously after function 6, shutdown mode is activated and the battery will send a signal
to switch off in 4sec.
Further holding the button causes the BMS to delay complete shutdown for a maximum of 3 minutes. This
operation is used when the technician wants to continue read or write parameters after shutdown.
