11.4.2 Error Code Listing
No.
Error text Cause Solution
1
Pulse rate overflow Pulse rate > 520,000 cps - Check configuration of application, or
calculation
2
No pulses from
detector
Fault in detector Error in detector
-Multiplier or probe electronics faulty
3
HV wrong HV < 500V or >1500V, outside
controlled range
- Error in detector
-Multiplier or probe electronics faulty
5
Measuring range
for current output
0/4-20mA faulty
Upper limit is smaller or equal to
lower limit (triggered during cali-
bration calculation)
- Check measuring range input
6
Detector tempera-
ture > 65°C
Detector temperature has ex-
ceeded 65°C
- Detector too warm, provide adequate
cooling
7
Trouble with detec-
tor communication
Data transfer between detector
and evaluation unit faulty
- Check connection terminals of cable
-Detector or evaluation unit faulty
-Broken cable
9
Detector tempera-
ture > 85°C
Detector temperature has ex-
ceeded 85°C
- Detector too hot, provide adequate
cooling
10
No calibration No calibration coefficient available
or not calculated
- Enter or calculate coefficient
11
Power fail
>1 month – time?
The date has changed since the
last operation by one month
- Check date
-Battery still OK?
12
No input allowed Instrument locked by password - Enter password
32
Wrong password Wrong password input - Enter correct password
34
Wrong input value Wrong parameter entry - Input lies outside range
35
Calibration error Parameters for calculation of cali-
bration curve are missing
- Check absorption coefficient and tare
38
Wrong product Measurement product is not the
same as product while reading the
calibration count rates
- Adapt product to calibration product
39
Time constant 1
< 1s
Time constant 1 too small - Input value has to be > 1
40
Time constant 2
< 1s
Time constant 2 too small - Input value has to be > 1
41
min. measuring
range not reached
Enter negative measuring range - Check final value
(only with square or cubic curve)
42
max. measuring
range exceeded
Measuring range input lies above
the limit
- Check final value
(only with square or cubic curve)
43
Rate Overflow With twisted measuring range - Check input
44
Current input error Input current above 23 mA - Check power source
46
Check external
mass counter set-
ting
Input is outside the limits and is
ignored.
(triggered when changing parame-
ters – measuring range or mass
counter)
- Increase step-width of mass counter or
reduce maximum measuring range
(safety circuit, so relay output can still
follow)
47
Check external
mass counter set-
ting
Input is outside the limits and is
ignored.
(triggered when changing parame-
ters – measuring range or mass
counter)
- Increase step-width of mass counter or
reduce maximum measuring range
(safety circuit, so relay output can still
follow)
