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
®
Technical Data.
Cl
2 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
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.

3 Installation
Note:
Avoid any force (e.g. by thumb) on the sensor element during operation or installation. Electronics can be destroyed by static electricity. Therefore, do not touch the equipment without a wrist strap connected to ground or without standing on a conductive floor (acc. to DIN EN100015).
3.1 Mounting Instructions
When choosing the mounting site please pay attention to the following:
The specific weight of Chlorine CL
2 is higher than that of air (factor 2.4).
Recommended mounting height is 0.2 m (0.7 ft.) to 0.3 m (1 ft.) above floor.
Choose mounting location of the sensor according to the local regulations.
Consider the ventilation conditions. Do not mount the transmitter in the center of the airflow
(air passages, suction holes).
Mount the transmitter at a location with minimum vibration and minimum variation in temperature (avoid direct sunlight).
Avoid locations where water, oil etc. may influence proper operation and where mechanical damage might be possible.
Provide adequate space around the sensor for maintenance and calibration work.
Duct mounting
Mount only in a straight section of duct with minimum air vortex. Keep a minimum distance of 1 m
(3.5 feet) from any curve or obstacle.
Mount only in a duct system with a maximum air velocity of 10 m/s (2000 ft/min) or less.
Mounting must be performed so that the probe openings are in line with the airflow.
3.2 Installation
Open the cover. Unplug basic PCB carefully from the bottom part.
Fix bottom part by screws vertically to the wall (terminal blocks to the ground).
Replug the basic PCB at X4 and X5 with care. Replace the cover.
4 Electrical Connection
Consider static electricity See 3. Mounting
Installation of the electrical wiring should only be executed by a trained specialist according to the connection diagram, without any power applied to conductors and according to the corresponding regulations
Avoid any influence of external interference by using shielded cables for the signal line, but do not connect the shield.
Recommended cable for analog mode: J-Y(St)Y 2x2x0.8 LG (20 AWG), max. loop resistance 73
/km (20.8 /1000 ft).
It is important to ensure that the wire shields or any bare wires do not short the mounted PCB.

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:
CL
2 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 (Cl
2
)-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
Signal start at 0 V or 0 mA
40 mV = 0 ppm
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 Cl
2
(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.

5.4 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 IN
TEC
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. IN
TEC
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.
