The instrument provides an input suitable for different measuring range selectable by dip-switches Converts the input signal into a standard 0-10 V d.c. proportional to the selected measuring range, which is delivered to the alarm circuits and to the analog output A highly stabilized power supply to load cells provided with short circuit protection which shut-off the load cell supply in case of short circuit (the instrument is reset by a new power-on of the instrument) Two alarm circuit are provided which can be selected between high or low alarm. Alarm set-points are adjustable over full...

Connect the wiring according to the terminal board connection drawing and in accordance with applicable standard and regulation of the country of installation. Provide an external switch on the power supply with protection fuse (may be common to several instrument). WARNING: 1) Load cell and analog signal wiring must run separate by power cables. 2) If required to optimize EMC immunity (degradation level for tests according to AӔ criteria < 4%), install ferrite cores on load cell and/or power supply cable inputs and/or install load cell cable into metallic sheet connected to ground OVERALL...
