Operation Connect the operation power supply to the Main Unit.
power supply
Trigger input Input terminals of the external contact from where a trigger signal is
applied.
No. 3: Collector of the NPN transistor, No. 4: Emitter of the NPN transistor
RS-485 Connect the RS-485 communications line.
No. 5: +, No. 6: -
PE A protective earthing terminal.
NC Do not connect anything to this terminal.
Compares the measurement value and alarm value 1, and outputs an
alarm.
No. 13: Collector of the NPN transistor, No. 14: Emitter of the NPN
transistor
Compares the measurement value and alarm value 2, and outputs an
alarm.
No. 15: Collector of the NPN transistor, No. 16: Emitter of the NPN
transistor
Provides notification that measurement is in progress. The output is
during normally open (OFF) You can use this output to design an interlock circuit
measurement to prevent accidental restart of the load during measurement operation.
No. 17: Collector of the NPN transistor, No. 18: Emitter of the NPN
transistor
Provides notification about system error in the Main Unit. The output is
error output normally closed (ON).
No. 19: Collector of the NPN transistor, No. 20: Emitter of the NPN
transistor
