Electrochemical Chlorine Transmitter
1 Intended Use
The PolyGard Cl analog/digital gas transmitter AT-1193 with digital processing of the measuring values and
temperature compensation is used for the continuous monitoring of the ambient air to detect the presence
of
Chlorine gas. Main application ranges are waterworks, sewage plants, swimming pools etc.
The intended sites are all areas being directly connected to the public low voltage supply, e.g.
residential,
commercial and industrial ranges as well as small enterprises (according to EN50 082).
The PolyGard® Cl2 analog/digital transmitter must not be used in potentially explosive atmospheres.
The
transmitter must only be employed in areas within the environmental conditions as specified in the
Technical
Data.
2 Functional Description
2.1 Control Mode
The analog output can be selected as current signal with (0)4-20 mA or as voltage signal (0)2-10 V. In the 4-
20
mA mode and without any supplementary options, the AT-1193 also works in the 2-wire technique.
2.2 Sensor
The sensor portion of the transmitter is a sealed electro-chemical cell with three electrodes, sensing,
counter
and reference. The ambient air to be monitored diffuses through a membrane filter into the liquid
electrolyte of
the sensor. The chemical process of the measurement is one of reduction where one
molecule of the target
gas is exchanged for one molecule of oxygen. The reaction drives the oxygen
molecule to the counter
electrode, generating a DC microampere signal between the sensing and
reference electrodes. This signal is
linear to the volume concentration of the sensed gas. The signal is
evaluated by the connected amplifier and
transformed into a linear output signal.
Electrochemical processes always lead by and by to a loss of sensitivity. Therefore regular calibration of
zero-
point and gain is obligatory. See also section 6.
Caution:
There is a small quantity of corrosive liquid in the sensor element. If in case of damage persons or
objects
touch the liquid, you have to clean the affected areas as fast and carefully as possible with tap
water. Out of
use sensors must be disposed in the same way as batteries.

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 % O2, 80 % N) or chlorine-free ambient air.
 Test gas bottle with Cl2 (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: CL2 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.

5.2 Calibration
Manual calibration is only possible if the transmitter is equipped with the push-button “Zero” and
the
potentiometer “Gain” (= version for manual calibration).
5.2.1 Zero-point
 Connect digital voltmeter to pin “Test”.
 Connect calibration adapter carefully to the sensor element.
 Apply synthetic air (150 ml/min; 1 Bar (14.5 psi) ± 10%), or Chlorine (Cl2)-free ambient air.
 Wait 2 minutes until the signal is stable, push button “Zero” for 5 seconds.
After successful calibration the measuring signal is corrected automatically. Depending on
the
selected signal starting point the measuring signal shows the following values:
Signal start at 2 V or 4 mA 40 mV = 0 ppm
Signal start at 0 V or 0 mA 0 mV = 0 ppm
If the zero-point is out of the admissible range (> 20 mV at starting point 0% / > 60 mV at
starting
point 20%) before calibration, there is no correction of the measuring signal. The
sensor has to be
replaced.
 Remove calibration adapter carefully by turning lightly. Check the sensor for correct mounting
5.3.2 Gain
 Connect digital voltmeter to pin “Test”.
 Connect calibration adapter carefully to the sensor element.
 Apply calibration test gas Cl2 (150 ml/min; 1 Bar (14.5 psi) ± 10%).
 Wait three minutes until the signal is stable, adjust control voltage with potentiometer ”Gain” until
the
signal corresponds to the calculated value ± 2 mV, see “5.3.3 Calculation of Control Voltage”.
 Remove calibration adapter with a careful light turn. Check the sensor for correct mounting
By limiting the gain factor, calibration will not be possible any more when the sensitivity of the
sensor
reaches a residual sensitivity of 30 %. Then the sensor has to be replaced.
5.3.3 Calculation of Control Voltage
Signal start 2 V / 4 mA
Control voltage (mV) = 160 (mV) x test gas concentration Cl2 (ppm) + 40 (mV)
measuring range Cl2 (ppm)
Signal start 0 V / 0 mA
Control voltage (mV) = 200 (mV) x test gas concentration Cl2 (ppm)
measuring range Cl2 (ppm)
Example:
Measuring range 20 ppm
Test gas concentration 10 ppm Cl2
Control voltage: Signal start 2 V / 4 mA 120 mV
Control voltage: Signal start 0 V / 0 mA 100 mV
Signal start 2 V / 4 mA Signal start 0 V / 0 mA
160 (mV) x 10 (ppm) + 40 (mV) = 120 mV 200 (mV) x 10 (ppm) = 100
mV 20 (ppm) 20 (ppm)

5.4 Option Relay Output
The two relays are activated in dependence of the gas concentration. If the gas concentration exceeds
the
adjusted alarm threshold, the corresponding relay switches on. If the gas concentration falls below
the
threshold minus hysteresis, the relay switches off again.
The contact function for relay 2, NC (normally closed) or NO (normally open), can be selected via the
jumper
NO/NC. See fig 1 and 3. Relay 1 is equipped with a change-over contact.
Via the ModBus interface the two alarm thresholds and the hysteresis are freely adjustable at the PC within
the
measuring range. The procedure can be read from the user manual “ModBus Software”.
The following parameters are factory-set.
Alarm threshold 1 = Relay 1: 5 ppm
Alarm threshold 2 = Relay 2: 8 ppm
Switching hysteresis: 1 ppm
6 Inspection and Service
Inspection, service and calibration of the transmitters should be done by trained technicians and executed
at
regular intervals. We therefore recommend concluding a service contract with INTEC Controls or
one of their authorized
partners.
According to EN 45544-4, inspection and service has to be executed at regular intervals. The
maximum
intervals have to be determined by the person responsible for the gas warning system
according to the legal
requirements. INTEC Controls recommends checking the PolyGard Transmitter
every three months and maintaining it
every 12 months. If different intervals are indicated, always consider
the shortest interval.
Inspections and services must be documented. The date for the next maintenance has to be affixed to
the
transmitter.
6.1 Inspection
The PolyGard Transmitter should be checked regularly by a competent person. The following has to be
checked in particular:
 Maintenance/ calibration interval not exceeded.
 Visual inspection of the transmitter including cable for damage etc.
 Remove dust deposits, especially at the gas inlet.
6.2 Service and Calibration
When performing the maintenance you have to do the calibration and the functional test in addition to
the
inspection.
 Calibration: See section 5.
 Functional test: Check the output signal at the test pins during calibration.
