4.1 Wiring Connection
Open the cover. Unplug basic PCB carefully from terminal blocks X4 and X5.
Insert the cable and connect cable leads to terminal blocks. See fig. 1.
Replug the PCB in the terminal blocks X4, X5 with care. Replace the cover.
Note: The connection of the power supply at the output signal (X4 pin 4) can destroy the transmitter.
5 Commissioning
Consider commissioning instructions at any exchange of the sensor element as well.
Only trained technicians should perform the following:
Check mounting location.
Select output signal form: Current or voltage, and starting point 0 or 20%. See fig. 4.
Check power voltage.
Check PCB AT03 for correct mounting at X4 and X5.
Required instruments for commissioning (calibration) of the transmitter:
Test gas bottle with synthetic air (20 % O
2
, 80 % N) or chlorine-free ambient air.
Test gas bottle with Cl
2
(ppm) in the range of 30 – 70 % of the measuring range. Rest is synthetic air.
Gas pressure regulator with flow meter to control the gas flow to 150 ml/min.
Calibration adapter with tube. Calibration set CONKIT-E/CH-AT. See fig. 5.
Digital voltmeter with range 0 – 300 mV, accuracy 1%.
Small screwdriver.
Note:
Prior to calibration the sensor must be connected to the power supply and fully stabilized for at least 6
hours without interruption.
Please observe proper handling procedures for test gas bottles!
Attention:

calibration gas is toxic, never inhale the gas
Symptoms: Chemical burn, dizziness, headache and nausea.
Procedure if exposed: Take the victim into fresh air at once, call a doctor.
5.1 Correction of the Zero-point at the Analog Output Signal
The analog output signal is factory set to the zero-point. If necessary, a manual adaptation of the analog
signal is possible within 10 sec. after having applied the supply voltage.
Jumper 0-20 % for signal start has to be set (= 4 mA or 2 V).
Connect digital voltmeter (300 mV) at test pint “Test” (measuring signal ~ 40 mV = 4.0 mA).
Switch on the operating voltage.
Each pressing on the “Zero” push-button increases the signal by + 0.5 mV (0.05 mA). Press the
button repeatedly until the measuring signal reaches 40 ± 0.2 mV. After 44mV the signal starts
again at 36 mV. The correction is only possible within the 10 seconds after having switched on the
power supply. An impulse pause of more than 10 sec. cancels the release of the correction
function.
