Current analog values:
-- Optical system value: (display of the current contamination value)
000 . . . 170 Initial set--up value for a new detector.
000 . . . 350 Normal working range.
350 . . . 450 Slight contamination exchange detector soon.
450 . . . 510 Heavy contamination exch an g e detector immediately!
as of 511 O fault op t ical sensor is switch ed off!
-- Optical system value for special O 400 L SN for RAS 100 LSN:
000 . . . 500 Initial set--up value for a new detector.
000 . . . 700 Normal working range.
700 . . . 800 Slight contamination exchange detector soon.
800 . . . 880 Heavy contamination exch an g e detector immediately!
as of 881 O fault op t ical sensor is switch ed off!
-- Temp. value [°C]: (display of the current measurement value of the temp. probe)
--20...+65°C OT 400 E LSN / T 400 E LSN.
--10...+50°C OT C 410 E LSN.
-- CO value: (display of the current measurement value of the CO sensor)
The CO value specifies the currently--measured CO concentration. Here the
specified number is calculated as the difference between the current measurement
value and the stand--by value stored in the detector. The CO concentration
displayed lies in the range between 0 (normal state) and 555 (max. measurement
value of the sensor).
Operating hours counter: display of the duration of operation since the initial
start--up of the detector.
Error code C malfunction: (cause, effect, and troubleshooting)
Error code Cause of trouble and troubleshooting
01000000 General C malfunction!
Possible causes:
-- malfunction of the temperature sensor
-- maximum operation duration (5 years) of the C--sensor has been exceeded.
T--/ and C sensors are switched off, the optical sensor is still operating.
. Exchange detector immediately!
01100000 The impedence of the electrochemical cell is too high!
The C sensor is switched off, the rest of the sensors are still operating.
. Exchange detector immediately!
01010000 The permissible operating temprature range (--10_Cto+50_C) has been exceeded!
The C--sensor is switched off, the rest of the sensors are still operating.
01001111 Malfunction due to read/write error in the EEPROM!
. Detector is switched off and must be exchanged immediately!
00000xxx Number of read/write errors in the EEPROM!
Contamination:
The optical initial set--up value of a new detector is stored in the integrated EEPROM
during the finalinspection. The contaminationvalue specifiesby how much this analog
value has increased in comparison to the delivery state.
