Description
2.2 Functional description
2.2.1 Principle of operation of the DrägerSensor
® 1
EC
The electrochemical DrägerSensor
EC are electrochemical transducers for measuring the partial pressure of a gas under atmospheric conditions.
The ambient air diffuses through a membrane in the liquid electrolyte of the sensor. A measuring electrode, a counter­electrode and a reference electrode are in the electrolyte. An electronic potentiostat circuit maintains a constant electrical voltage between the measuring electrode and the reference electrode. The voltage, the electrode and the electrode material are selected to enable the monitored gas to be electrochemically converted at the measuring electrode. The electrons flowing during the reaction are a gauge for the gas concentration. There is an electrochemical reaction with oxygen from the ambient air at the counter electrode at the same time.
2.3 Intended use
The Dräger Polytron 8000 is an explosion-proof device for continuous monitoring of toxic gases or oxygen in the ambient air, corresponding to the integrated DrägerSensor. The housing for the device consists of robust, non-corroding stainless steel or aluminum and is suitable for indoor or outdoor applications. The unit can be connected to a Dräger monitoring system or a programmable logic controller (PLC) by means of a sealed conduit or an appropriately approved cable gland. With the optionally integrated relay module, the device can be operated without a central controller (with additional local alarm signaling). The device is designed for fixed installation and is approved for use in potentially explosive atmospheres, see chapter 2.5 on page 6.
2.4 Intended area and conditions of use
Hazard areas classified into zones:
The device is only designed for use in Zone 1 or Zone 2 potentially explosive atmospheres for which a temperature range as specified on the device must be observed and in which gases of Explosion Groups IIA, IIB or IIC and Temperature Classes T4 or T6 (depending on maximum ambient temperature) or dust of Groups IIIA, IIIB or IIIC may occur. The temperature range specified for the device must be observed.
Hazard areas classified into divisions:
The device is only designed for use in potentially explosive atmospheres of Classes I&II, Div. 1 or 2, in which gases or dust of Groups A, B, C, D or E, F, G and Temperature Classes T4 or T6 (depending on maximum ambient temperature) may occur. The temperature range specified for the device must be observed.
2.5 Approvals

3 Installation
3.1 General information for the installation
The selection of a suitable mounting location is crucial for the effectiveness and performance of the entire system. Every detail of the installation must be thoroughly thought out. The following must be noted in particular:
z The local and national rules and regulations for the
installation of gas measuring systems.
z The applicable regulations for running and connecting
power and signal cables to gas measuring systems.
z The full extent of environmental influences to which the
device will be subjected.
z The physical properties of the gases and vapors to
be measured.
z The details of the particular application (e.g., potential leaks,
air movements/flows, etc.).
z accessibility for required maintenance activities. z The geometric of the accessories that are used with
the system.
z All other limiting factors and stipulations that may affect
the installation of the system.
z For installation without a conduit, an approved cable gland
(e.g. Hawke A501/421/A/¾" NPT or equivalent) must be used (see chapter 12 on page 31). To increase the RF interference immunity, it may be necessary to connect the cable screen to the cable gland and to the control unit.
z The explosion proof enclosure has three ¾" NPT
connections, which can be used for field wiring, the direct attachment of a sensor or wiring an external sensor. Unused openings must be closed off with a plug. For the correct tightening torques for cable bushings, plugs, sensors and connectors, see chapter 12 on page 31.
z The secondary circuit is supposed to be supplied from an
isolating source (does not apply to relay contacts).
z The optional e-Box has up to four 20 mm connections,
which can be used for field wiring or wiring an external sensor. The permissible cable diameter is 7 to 12 mm.
z If the device is installed in locations where ambient
temperatures of over 55 °C prevail, appropriate cables which are specified for use at temperatures of 25 °C above the maximum ambient temperature must be used.
z Strip back the insulation on conductors by 5 to 7 mm. z Connect the cable as shown in chapter 3.5 on page 8
(shown here also with protective ground) or chapter 3.6 on page 9.
z The connecting wires for the optional relay module must
be selected and fused according to the rated voltages, currents and environmental conditions.
z When stranded conductors are used, an end ferrule must
also be used.
3.2 Restrictions on the installation
z The device requires a DC voltage between 10 and 30 V.
The minimum supply voltage of 10 V and the cross-section of the conductors used determine the distance of the device from the supply or the central controller (see chapter 12 on page 31). The device is designed for cables of size 12 to 24 AWG (0.2 to 2.5 mm
2
). Use a three-
wire, screened cable as a minimum.
z The device must not be subjected to any radiant heat
(e.g. direct sunlight) as this will result in a temperature rise above the specified thresholds (see chapter 12 on page 31). The use of a reflective screen is recommended.
z The housing is weather resistant and suitable for outdoor
applications. The use of the optional splash guard is recommended to protect the sensor from water and dust.
z The device must be installed and operated in an environment
which conforms to the stated specifications (see chapter 12 on page 31).
z To insure proper operation of the device, the impedance of the
4 to 20 mA signal loop must not exceed 500 ohms. Depending on the operating voltage and according to the application (e.g. HART operation), certain minimum impedances must be adhered to (see chapter 3.3 on page 7). The conductors for the power supply must have an adequately low resistance to insure the correct supply voltage at the device.
3.3 Impedance range of the signal loop
Devices with a HART interface can be operated with HART communication or in HART Multidrop mode.
NOTICE
A dust cap can be fitted to the cable entry of the device. This cap is only used for transport purposes and must be removed before the device is connected to a sealed conduit.

5.1 Calibrating the device
1. Connect the pressure regulator to the test gas cylinder.
2. Attach the calibration adapter to the sensor.
3. The gas flow should be approx. 0.5 L/min.
4. Connect the tube to the calibration adapter.
1 Pressure regulator 2 EC sensing head 3 Calibration adapter 4Tube 5 Test gas cylinder
5.1.1 Zero point calibration
1. Select Calibration > Zero Calibration and confirm.
The Maintenance signal is transmitted. The message Apply zero gas appears.
2. Apply zero gas (synthetic air or nitrogen) to the sensor.
3. Select Next and confirm.
The current measured value is displayed.
CAUTION
Danger to health! Do not inhale the test gas. Observe the hazard information in the corresponding safety data sheets. Provide venting into a fume hood or outside the building.
Always calibrate the zero point first before the sensitivity. Otherwise the calibration will be faulty!
NOTICE
Calibration is not possible if the date and time are not set (see chapter 8.2.3 on page 20).
Dräger recommends calibrating devices with target gas. This method of target gas calibration is more accurate than a surrogate gas calibration. A surrogate gas calibration may only be performed as an alternative if a target gas calibration is not possible.
!
i
i
NOTICE
Ambient air can also be used instead of nitrogen or synthetic air to zero the sensor, provided it is insured that the ambient air contains no target gas or any other gas for which the sensor may be cross-sensitive to (see the details in the sensor data sheet). In this case, neither a test gas cylinder nor a calibration adapter is required for the zero point calibration.
The zero point cannot be calibrated for the O
2
sensor
and exclusively Nitrogen must be used for testing.

Yellow Fault LED Lights when a fault is present
(see chapter 9 on page 27).
Red Alarm LED Gives single flashes when an A1 alarm
is present. Gives double flashes when an A2 alarm is present. If an alarm is configured as acknowledgeable and the alarm is acknowledged, the LED lights. Alarm hierarchy: A2 has a higher priority for the LED than A1. However, the A1 and A2 relays operate independently of one another, i.e. if A1 is acknowledgeable and A2 is not and the gas concentration is so high that A1 and A2 are triggered, an acknowledgement results in the A1 relay dropping out. However the red LED continues to give double flashes as long as the A2 condition exists.
