Status output
Works setting: Error messages
Switch No. 2: OFF
This switched output can optionally be configured for:
•
1) Signalling the flow direction
•
Error messages: Fault (System error: coil current error, amplifier error DAT error,
EEPROM error, ROM error, RAM error)
Alarm (Process error: measuring range exceeded, v
≥
12.5 m/s)
Supply failure)
The status output acts as a normally closed contact, i.e. in normal operation fault, the
output is closed (transistor conducting, see Fig. 36).
1) The “error messages” are always activated in the fiscal meter.
Note!
The behaviour of the outputs in the event of a fault is described in Chapter 5.1.
