SC2-AT6 – UserManual

Intended Use

The SC2 sensors are designed for the measurement of toxic gases and oxygen in a wide range of applications with

the PolyGard®2 Series. The AT6 sensor/transmitter operates with 24 VDC and outputs an analog 4-20 mA standard

signal. Both the SC2 sensor cartridge and AT6 sensor/transmitter utilizes similar technologies and thus collective

referred to as same (“sensor cartridge”,”sensors”) in this document unless otherwise noted.

The sensors must not be used in potentially explosive atmospheres. They must only be employed in areas within the

environmental conditions as specied in the Technical Data.

1 Functional Description

1.1 General

The SC2 sensor includes a microprocessor for measurement value processing in addition to the gas sensor element

and the measuring amplier. All data and measured values of the sensor element are stored in a fail- safe way in the

microprocessor and are digitally transferred via the local bus to the PG2 devices. The calibration management is also

integrated in the microprocessor of the sensor cartridge.

The AT6 sensor/transmitter works according to the same principle as the SC2 series with the exception that the AT6

outputs an analog signal of 4-20 mA (2-10 V as an option).

1.2 Measuring Mode

See description on datasheet for the specic PG2 device.

1.3 Special Mode

See description on datasheet for the specic PG2 device.

1.4 Sensor Element for Toxic Gases and Oxygen

The sensor element is a sealed electro-chemical cell with three electrodes, sensing, reference and counter or with two

electrodes, sensing and reference. The ambient air to be monitored di󰀨uses through a membrane lter into the liquid

electrolyte of the sensor. The chemical process of the measurement is one of oxidation 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 amplier 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 necessary. See section 5.

There is a small quantity of corrosive liquid in the sensor element. If in case of damage persons or

objects touch the liquid, clean the a󰀨ected areas immediately and carefully as possible with tap water.

Out of use sensors must be disposed in the same way as batteries.

Certain substances and gases in the ambient air to be monitored can a󰀨ect the sensitivity of the sensor element or

destroy the sensor completely. This is considered sensor poisoning.

The following are currently known:

• Polymerizing substances, such as ethylene oxide, acrylonitrile, butadiene, styrene, silicone.

• Corrosive substances, such as halogenated hydrocarbons.

• Catalytic poisons, such as sulfur and phosphor compounds, silicon compounds, metal vapors.

SC2-AT6 – UserManual

1.5 Sensor Element for Combustible Gases

The integrated sensor works according to the catalytic bead principle. The ambient air to be monitored di󰀨uses through

a sintered metal disk into the sensor. Here the combustible gases and vapours are burned catalytically at a heated

detector element (pellistor). The resulting combustion heat also heats up the detector element. This heating changes

the resistance of the detector element which is proportional to the partial pressure of the combustible gases.

In addition to the catalytic detector element, the sensor also has a similarly heated inactive compensator element.

Both elements are part of a Wheatstone measuring bridge. Environmental inuences such as temperature, air humidity

or thermal conductivity of the ambient air to be monitored a󰀨ect both elements to the same extent so that these

inuences have no signicant e󰀨ect on the measuring signal.

Certain substances and gases in the ambient air to be monitored can a󰀨ect the sensitivity of the sensor

element or destroy the sensor completely. This is called poisoning.

The following are currently known:

• Polymerising substances, such as ethylene oxide, acrylonitrile, butadiene, styrene, silicone.

• Corrosive substances, such as halogenated hydrocarbons.

• Catalytic poisons, such as sulphur and phosphor compounds, silicon compounds, metal vapours.

• Organic solvents

For testing the sensor, do not use a lighter. If gassed with a lighter the sensor cannot be employed for reliable

measurement and must rst be recalibrated. The sensor may be damaged, and the calibration should then be

repeated at much shorter intervals. In addition, the resulting amount of heat can lead to the mechanical destruction of

the sensor. The product warranty is void by fumigation with a lighter.

1.6 Infrared Sensor Element for CO2

The integrated sensor is based on the principle of the infrared absorption of gases and accomplishes highest

requirements concerning accuracy, reliability and economy. The sensor technology uses the individual absorption

spectrum of the carbon dioxide gas and determines its exact concentration through its accurate, quantitative analysis.

The infrared principle nearly eliminates the cross-sensitivity to other gases.

An integrated evaluation electronic system reliably compensates all drift and temperature inuences and therefore a

genuine measurement result is guaranteed.

Certain substances and gases in the monitored ambient can a󰀨ect the sensitivity of the sensor element

or destroy the sensor completely. This is called poisoning.

The following are currently known:

• Polymerising substances, such as ethylene oxide, acrylonitrile, butadiene, styrene, silicone

• Corrosive substances, such as halogenated hydrocarbons

• Catalytic poisons, such as sulphur and phosphor compounds, silicon compounds, metal vapours

2 Installation

Electronics can be destroyed by electrostatic discharge (ESD). Therefore installation work should

be done only by persons connected to ground, e. g. by standing on a conductive oor or by taking

appropriate grounding measures (acc. to DIN EN 100015).

2.1 Mounting Instructions

• Choose mounting location of the sensor

according to the local regulations.

• Consider ventilation conditions! Do not

mount the sensor near the airow (air

passages, suction holes etc.).

• Mount the sensor at a location with

minimum vibration and minimum variation

in temperature (avoid direct sunlight).

• Avoid locations where water, oil etc. may

inuence proper operation and where

mechanical damage might be possible.

• Provide adequate space around the

sensor for maintenance and calibration

work.

5.1 Calibration Process

Prior to calibration, activate the mode “Special Mode” at the basic device via tool or software: only then the calibration

menu is enabled. During the special mode the basic device doesn’t issue alerts.

For visual illustrations, consult the online document “PolyGard2-Sensor-Calibration-Procedure.”

• Connect calibration adapter carefully to the sensor cartridge

• Connect calibration tool to the printed circuit board

• Select the Sensor Cartridge to be calibrated by selecting the gas type

Zero calibration

• For toxic, oxygen & combustible sensors

• Apply synthetic air (ow rate according to the table “calibration”, 1 bar ± 10%) to the Sensor Cartridge.

• For infrared CO2sensors

• Apply pure nitrogen 5.0 (ow rate according to the table “Calibration”, 1 bar ± 10%) to the Sensor Cartridge.

• The current zero o󰀨set and the o󰀨set value of the rst calibration is read with “Read”.

• When the value is stable, the new zero o󰀨set factor is calculated with “Calibration”.

The new o󰀨set factor is checked for plausibility and stored in the bu󰀨er memory. The current measured value is output

with the new o󰀨set factor and the o󰀨set display is updated.

• With “Save” the new o󰀨set factor is written in the SC memory, only then the Zero calibration has been

successfully completed. If you exit the menu without pressing “Save”, the original o󰀨set data for the measured

value calculation will continue to be used.

• ALERT: With a zero reading > 10% of measuring range during the zero calibration, zero calibration is not

possible.

Gain calibration

• Enter test gas concentration:

• For toxic, oxygen and CO2, value between 30-90% of the measuring range.

• For combustibles, value between 30-70% of the measuring range.

• The current sensor element sensitivity is read with “Read”.

• Apply test gas (ow rate according to the table “Calibration”, 1 bar ± 10%) to the Sensor Cartridge.

• When the value is stable, the new gain factor is calculated with “Calibration”.

The new gain factor is checked for plausibility and stored in the bu󰀨er memory. The current measured value is output

with the new gain factor and the sensor element sensibility is updated.

• With “Save” the new gain factor is written in the module’s memory, only then the gain calibration has been

successfully completed. If you exit the menu without pressing “Save”, the original gain data for the measured

value calculation will continue to be used.

Calibration will not be possible when the sensitivity of the sensor drops to 40% or lower; the Sensor

Cartridge must be replaced.

SC2-AT6 – UserManual

5.2 Exchange of Sensor Cartridge

Instead of the on-site calibration, the used SC can be replaced simply and conveniently by a calibrated one.

The communication of the sensor cartridge to the sensor board is continuously monitored during

operation and results in an immediate error message on the gas controller in case of fault or interruption.

When replacing the sensor unit, the communication of the local bus is interrupted when unplugging the

SC connector which leads to an immediate triggering of the error message.

• Disconnect the SC connector from the printed circuit board (error message will be activated).

• Loosen the locknut.

• Remove used SC.

• Take calibrated SC out of the original packaging, check for gas type, measuring range and valid calibration

date.

• Insert the SC and re-tighten with lock nut.

• Insert the SC plug into the socket at the circuit board. Check plug for proper connection.

The local bus communication is automatically established and tested. At the same time the gas type and the

measuring range of the “new” SC are compared with the data stored in the circuit board. If they match and the

communication is correct, the error message will be automatically acknowledged in the Gas Controller.

The yellow LED of the circuit board ashes with a pulse of 1 sec. as long as the SC connector is disconnected

(communication error). After the local bus communication has been re-established and the conformity test has been

successful, the LED goes into ashing mode with 3 sec. pulse duration until the sensor’s warm-up time is over.

Apply a dened gas concentration on the sensor element with the help of the gas generator and check the

measurement signal at the analog output or at the relay outputs.

The entire cycle “Sensor Element > Sensor Cartridge > Local Bus > Sensor Board > Field Bus > Controller” is

observed and completed.

6 Inspection and Service

Inspection, service and calibration of the sensor should be done by trained technicians 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 have to be executed at regular intervals. The maximum intervals

have to be determined and respected by the person responsible for the gas warning system according to the legal

requirements. INTEC Controls recommends employing the common inspection and service intervals as specied in

the general regulations of the gas measuring technique. The recommended calibration intervals depend on the sensor

element and can be read from the table “Calibration”. If there are di󰀨erent intervals, always observe the shortest one.

Inspections and services must be documented. The date for the next maintenance has to be a󰀩xed to the sensor.

6.1 Inspection

Gas sensors should be controlled regularly by a competent person according to EN 45544-4. The following has to be

checked in particular:

• Maintenance/ calibration interval not exceeded.

• Visual inspection of the sensor including cable for damage etc.

• Remove dust deposits, especially at the gas inlet.

• The lter at the gas inlet has to be replaced if extremely dirty.

SC2-AT6 – UserManual

6.2 Service and Calibration

When performing the maintenance you have to do the calibration and the functional test, see chapter 5, in addition to

the inspection.

A xed calibration interval is stored for each sensor type.

SC2 Sensor heads:

If this interval is exceeded, a digital maintenance message is generated and forwarded. Performing the calibration

automatically deletes this message.

AT6 Sensor heads:

If this interval is exceeded, the current output of the AT6 goes to a xed 19 mA signal. For new devices (factory

calibration), the interval may be exceeded by a factor of 1.5.

After voltage recovery, there is a dened interruption of this message. This can be of use in order to employ the

device without the maintenance message for a few days (adjustable in system parameters -> error time, value

range> 1) until the calibration is repeated.

Performing the calibration automatically deletes this message.
