S Relays for MR
A relay can be assigned to the range switchover of each
component. This guarantees reliable assignment of the analog
signal to the currently active range, especially in autorange mode
(see Section 5.9.1).
S Relays fo r status
You can use this dialog to apply the signalling of various operating
states of the device as an event for relay control (R= Relay). The
following signals are possible (see also Table 5-5):
Fault: The occurrence of a fault message
Maintenance request: The occurrence of maintenance request
(appliedtorelay5inFig.)
CAL/MEAS: Switching over from measurement to AUTOCAL
(appliedtorelay6inFig.)
Service switch: The occurrence of a function control.
S External valves
You can use this to trigger external solenoid valves via relay
contacts:
Zero gas: The zero gas supply which is also triggered with
AUTOCAL
Span gas: The calibration gas supply (assigned to relay 7 in Fig.;
see Section 5.10.3.2)
Sync: The synchronization of an AUTOCAL with other devices
within a system (assigned to relay 8 in Fig.; see Section 4.3.3).
