Date/time
The clock has a battery backup in chromatographs
fitted with a
PCPU-1
Chromatographs with a
backup battery. Following a power failure, the
clock is set to 1.1.1980, 0:00 hours.
From software version V7.0 onwards (operation and
control software!) the clock in the chromatograph
can be synchronized with the clock in the control
unit. This must be selected during installation. The
time of the control unit is then sent to all connected
chromatographs approx. once a minute.
Baseline monitoring
The baseline of the FID can be monitored. An
alarm is output if the FID flame is extinguished in
process operation. The chromatograph becomes Not
ready, and never Ready again; process operation is
blocked! The only remedy is to reset the chromato-
graph.
Cause: the baseline monitoring function only oper-
ates whilst a run was being carried out. From con-
trol software version V6.0 onwards, the baseline
alarm is reset when the FID is ignited.
Detailed information on the baseline monitoring func-
tion can be found in Register 5 under Baseline monitor-
ing.
