E101

E106
Alarm Fault in instrument electronics
- Check supply voltage
- Call Hauser Service
E201 Alarm Fault in detector, pulse rate too low
(DG 17 = 0, DG 27 < 1 Hz, DG 57 < 2 Hz)
- Check detector
E202 Alarm Pulse rate > max. possible pulse rate (detector possibly defective)
(DG 17/27 > 2 x empty calibration countrate; DG 57 ca. 110% of
max. countrate - dependent on temperature and calibration value)
- If calibration was made with build-up on the sides of the vessel, it is
possible that this has fallen off and less radiation is being absorbed.
In this case recalibrate and set V0H1 equal to e.g. 20.
- Check detector
- Check for external radiation source
E204 Alarm No temperature measurement (DG 57 only)
E206 Alarm LED reference measurement outside limits 30
…
95% (DG 57 only)
E401 Alarm No signal from detector,
- Check the wiring. Take into account the polarity.
- If the wiring is correct, check the voltage at the terminals of the
detector. The value should be 13.7 +/- 3V.
If the voltage is correct, a mistake is present at the detector. Exchange
detector.
- If the voltage is not correct at the detector, check for the same
voltage at the output of the transmitter FMG 671. If the output voltage
is not correct, the transmitter is defective.
E404 Alarm Wrong detector connected
E610 Warning Detector data have been changed (DG 57 only)
- Check whether detector data chip (DAT) is inserted in card
or whether it corresponds to the detector connected
-- Re-calibrate, if detector exchanged
E613 Warning Instrument in simulation mode
- Switch back when finished
E615 Alarm Incorrect calibration points, e.g. through mix-up, repeat calibration
E630 Warning Calibration incomplete
E631 Warning Limit for switch point relay 1 exceeds maximum or drops below
minimum countrate
- re-enter
E632 Warning Limit for switch point relay 2 exceeds maximum or drops below
minimum countrate
- re-enter
E633 Warning Hysteresis relay 1 too small
- re-enter, increase integration time
E634 Warning Hysteresis relay 2 too small
re-enter, increase integration time
E635 Warning Difference between maximum and mimimum pulse rate too small
- increase integration time
- source too weak
E660 Warning Detector temperature > 55°C (DG 57 only)
