LOAD LIMITER
Limitation of the detected load through alarm and pre-alarm levels.
Overload control with double-security system by connecting two units.
Limitation of load (single and sum) for weighing systems up to 4 points, by connecting more units.
Load cell fail alarm and Set-up and calibration via keyboard and display board removable.
