5.1 Using the diagnostic box

Switch the diagnostic box on. Then connect it to the opto- coupler receptacle on sensor head bottom. Keep the LED`s and the phototransistors of the opto- coupler clean for proper data transmission.

5.1.1 Operation and error codes of the diagnostic box

Note: If a combination of push button operations is requested ( f. i. ST + ENT), the buttons must be operated in a short time distance.

Example: ST + ENT initiates a self test. The display says „WAIT-TEST RUN“ until the self test is finished.

Diagnostic box queries:

		Button	Display
		M	Measured value in ppm
		M + ENT	WAIT; after a while reading of actual measured value in ppm
		RA	Sensor head measuring range
		RA + ENT	Gas
		ST	Status passed (System OK) or error message (see 5.1.2)
		ST + ENT	(initiates self test), TEST Run
		FKT	Calibration factor
		ZERO + ENT *	ZERO RUN (start zero adjustment)
		* only available with systems with zero adjustment
Diagnostic box error messages:
	ERR INPU			Faulty or too slow input. Repeat.
	ERR KONZ			Calibration gas concentration out of range.
	ERR FACT			Calibration factor is out of range.
	DS.W.POS			Measuring range or gas not correctly programmed.
	WARN TIM			Time error during data transmission.
	WARN DTE			Faulty data transmission.
	WARN CHE			No self test due to too low temperature.
	TEMP.OU			Temperature out of the admissible range.
	TEMP.IN			Temperature is back in the admissible range.
	CH.BATT			Charge calibration box battery.
	(audible alarm)
	NO ZERO			Zero adjustment not possible. Wrong EPROM in sensor
				head and control module.
	PUMP RUN			Sensor is flushed with air because the gas concentration is
				too high.
	CAL END			Calibration routine has been cancelled with CE button.
	NO CALIB			Calibration not possible within the time limit.
