Totalizer Operation
Common Functions
Monitors contain two totalizers: Job and Grand The user can enable or disable the grand totalizer
function If grand totalizer is enabled, it shares the seven-digit display line with the job totalizer –
alternating between job and grand Grand totalizer rollovers are displayed with a count value that
increments at each rollover Totalizers are automatically backed up into non-volatile FLASH memory
every twenty minutes and prior to battery expiration; manually via keypad or when signaled via
Modbus (B30A/M/Y/Z only)
Totalizer Reset
B30A/B/L/M/S only: The job totalizer can be reset by momentarily contacting the total reset
terminal to ground or pressing MENU and ENTER simultaneously The grand totalizer can be reset
via selection in the advanced menu or modbus
OTE: N Modbus not applicable on solar powered units
B30W/X/Y/Z: *The job totalizer can be reset via the “through the glass” touch sensor, by
momentarily contacting the total reset terminal to ground or pressing MENU and ENTER
simultaneously The grand totalizer can be reset via selection in the advanced menu or Modbus
command
