5.9.1 Toggle Load Terminal Output Commands
Load Output
- force the load off. Useful for service/maintenance activities or ensuring the load does
not run for a period of time.
LVD Override (15 min)
- turn on the load when it is in Low Voltage Disconnect State for 15 minutes.
After 15 minutes the load will turn back off and resume LVD state. The user can override LVD and
unlimited number of times, but too many overrides will cause over-discharge and possible battery
damage.
5.9.2 Counters Commands
Clear-reset counters using commands:
All Resettable Counters -
resets the Resettable A-h and Resettable kW-h counter values to zero.
Resettable counters are intended to track mostly in the short-term, for example, accumulations since
a battery replacement, or a new load was added to a system.
All Total Counters
- clears the Total A-h and Total kW-h counter values to zero. Total counters are
intended to track long-term / lifetime accumulations of a system.
5.9.3 Toggle Battery Charger Command
Connect or disconnect charging functions using commands:
Manual Equalization -
Manually start or stop an equalize charge on a lead-acid battery. This
command is only functional for battery charging profiles with Equalization enabled
