7.8.4 Error Messages during Measurement
Error
no.
Message Cause, Remarks Remedy
1 Rate Overflow Count rate > 520000 High voltage wrong.
Replace detector
2 No Detector Rate Detector faulty Replace detector
3 Wrong HV Detector faulty Replace detector
4 Pt 100 wrong
temperature
Temperature measurement
activated and no Pt100
connected. Cable faulty.
Check cable, replace
detector or Pt 100.
Disable temperature
measurement.
5 4 –20 mA faulty Input current below 4 mA,
evaluation unit faulty.
Check input current,
replace, evaluation unit.
6 Detector
temperature >
65°C
Detector temperature too
high, detector faulty
Cool detector, if necessary,
replace it
7 Trouble with
detector
communication
Cable detector – evaluation
unit interrupted or too long or
cable resistance too high,
detector faulty
evaluation unit faulty.
Replace cable or use bigger
wire cross-section.
Replace detector
Replace evaluation unit.
8 Measurement
stopped
Measurement process stopped
via digital input
or
measurement stopped
because count rate threshold
has been exceeded or not
reached.
Open digital input.
Disable count rate
thresholds to identify fault.
9 Detector
temperature >
80°C
Detector temperature too
high,
Detector faulty
Replace detector
10 Not
calibrated
Measurement was started
without calibration
Perform calibration
11 Power fail > 1
month
Check date after long period
of power failure
When the If this error
message appears already
after a brief period of power
failure: replace Li-battery.
12 No input allowed Input locked via password Enter password
47 Rate < Minimum Enter actual count rate < than
entered min. count rate:
shielding container closed?
detector fault?
Replace detector
Open shielding container
48 Rate > Maximum Enter actual count rate > than
entered max. count rate:
detector fault?
pipeline empty and shielding
container not closed?
Replace detector
Close shielding container
61 Replace
photomultiplier
High voltage increased too
much.
Check plateau. Possibly
replace photomultiplier.
