The meaning of "N" and "X" in the "Driving voltage" columns is explained
in function 72 "Binary inputs."
Comment / effects
No effect when addressed
e.g.: Signaling by a gas preparation
unit: condensate overflow,
gas cooler defective or similar
Manual deletion of logbook entries is
possible. But if the cause of a fault or a
maintenance request has not yet been
corrected the corresponding message will
reappear in the logbook.
Relays under function 71 must be
configured for a functional check if, for
example, the function is to be checked in
the case of a second unit.
AUTOCAL must be parameterized (function
24)
For remote measuring range changeover,
autoranging (function 52) must be
deactivated.
Relay must be configured for zero gas and
the corresponding valves connected.
See also example 1, below
Relay must be configured for sample and
the corresponding valves connected.
See also example 1, below
Relay must be configured for sample and
the corresponding valves connected.
Before the sample gas valve is opened, the
other valves must have been connected.
The unit then switches to measurement
mode and all other processes which had
previously been activated (such as
calibration) are aborted.
Start calibration

Automatic measuring range changeover
Start AUTOCAL check (function 24)
A "Measurement protection" binary input
can be defined which has the following
effect:
if the unit is in the "Measurement'" state (no
functional check), it will remain in this state;
in other words:
- the unit can no longer be decoded
- the unit can no longer be set to "Remote"
- The message "Measurement protection
switched on" appears on the status line
of the measurement screen.
