2.2 Intended use

The Dräger Polytron 8000 is an explosion proof instrument for continuous monitoring of toxic gases or oxygen in the ambient air. The instrument is housed in a rugged stainless steel or aluminum enclosure for indoor and outdoor applications. The instrument can be connected through a sealed conduit or approved cable gland to a Dräger monitoring system or a Programmable Logic Controller (PLC). With the optional alarm relay configuration, the instrument can be operated as a stand­alone unit. The instrument is designed to be installed in permanent locations and is approved for use in hazardous, classified areas, see Section 10.1 on Page 37. With the optionally integrated relay module, the instrument can be operated without a central controller (with additional local alarm signaling).
For safe operation, the connection to a central controller is necessary. This also applies if all relays are connected because the fault relay is not activated during maintenance. In any case, the analog output must be monitored because it might indicate a special status by a current between 0 and 3.5 mA.
CAUTION
Not tested in oxygen enriched atmospheres (>21% O2). High off-scale readings may indicate an explosive concentration.

2.3 Intended operating area and conditions

Hazardous areas classified by zones:
The device is intended to be used only in hazardous areas classified Zone 1 or Zone 2, within a temperature range as marked on the device, where gases of explosion Groups IIA, IIB or IIC and temperature class T4 or T6 (depending on the maximum ambient temperature) or dusts of Groups IIIA, IIIB or IIIC may be present.
Hazardous areas classified by divisions:
The device is intended to be used only in hazardous areas Class I or II, Div. 1 or Div. 2, within a temperature range as marked on the device, where gases or dusts of Groups A, B, C, D or E, F, G and temperature class T4 or T6 (depending on the maximum ambient temperature) may be present.

2.4 Design

The instrument is powered by 10 to 30 VDC (see Section 10.4 on Page 41). Gas concentrations, status messages, and menu choices are displayed on a backlit graphic LC-display and 3 colored LEDs. The measured gas concentration is converted to a 4 to 20 mA analog (per NAMUR recommendation NE43) or a digital HART output signal. The instrument can be operated as current source or sink.
Navigation through the menu is done by taping a magnetic wand on the glass at the appropriate indicator.
WARNING
Danger of explosions. Not to be used in oxygen enriched atmospheres. None of the Polytron 8000 instruments are certified and approved to be operated in oxygen enriched atmospheres.
The instrument can be configured, calibrated and maintained non-intrusively without declassifying the area.

Installation

3 Installation

3.1 General information for installation

To ensure overall system performance and effectiveness, the selection of an installation site for the instrument is one of the most important factors. Strict compliance where possible and considerable thought must be given to every detail of installation, particularly:
the local, state, national codes and regulations that govern
the installation of gas monitoring equipment.
the electrical codes that govern the routing and connection
of electrical power and signal cables to gas monitoring equipment.
for non-conduit installations, an approved cable gland must
be used, see Section 10.1 on Page 37 (e.g. Hawke A501/ 421/A/¾” NPT or equivalent). It might be necessary to connect the shield of the cable to the cable gland and to the controller in order to improve RFI immunity.
the full range of environmental conditions to which the
instruments will be exposed to.
the physical data of the gas or vapor to be detected.the specifics of the application, (e.g. possible leaks, air
movement/draft, etc.).
the degree of accessibility required for maintenance
purposes.
the types of optional and accessory equipment that will be
used with the system.
any other limiting factors or regulations that would affect
system performance or installations.
the flameproof / explosion proof enclosure provides three
¾" NPT openings, which can be used for field wiring, direct attachment of a sensor or wiring of a remote sensor.
unused openings must be closed with a plug. For correct
tightening torques of conduit hubs, cable glands, plugs and sensor see Section 10.8 on Page 42.
secondary circuit intended to be supplied from an isolating
source (N/A for relay circuits).
the optional increased safety terminal box provides up to
four 20 mm openings, which can be used for field wiring or wiring of a remote sensor. The permissible cable diameter range is 7 to 12 mm.
when installed at locations exceeding ambient
temperatures of 55 °C, use only appropriate wiring, specified for at least 25 °C above the maximum ambient temperature.
strip wire insulation by 5 to 7 mm.connect the wires as indicated in wiring figure Section 3 on
Page 8 (also showing grounding conductor terminal).
the wiring for the optional relay module must be selected
and fused according to the rated voltages, currents and environmental conditions.
if stranded conductors are used, a ferrule must be used.

3.2 Installation restrictions

The instrument must have between 10 to 30 VDC at the
instrument. This ultimately determines the distance the instrument can be mounted from the controller or power supply. The instrument accepts wire sizes of 12 to 24 AWG (0.2 to 2.5 mm2). Use at least a three-conductor, shielded cable.
The instrument must not be exposed to radiant heat that
will cause the temperature to rise beyond the limits stated in see Section 10.6 on Page 41. The use of a reflecting shield is recommended.
The enclosure is weatherproof within environmental
parameters and suitable for outdoor installation. The use of the optional splash guard (6812510) is recommended to protect the sensor from water and dust.
Each instrument must be installed and operated in an
environment that conforms to the specifications, see Section 10 on Page 37.
To insure proper operation of the instrument, 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 observed (see Section 3.3 on Page 8). The conductors for the power supply must have an adequately low resistance to insure the correct supply voltage at the instrument.
NOTICE
i
i
The instrument may be equipped with a dust plug at the conduit entry. This plug is not explosion proof nor meant to be watertight, and must be removed before connecting the instrument to a sealed conduit or installation of a flameproof cable gland.

4 Operation

4.1 Normal operation

WARNING
Before leaving the instrument for normal operation, check the configuration and calibration for the proper settings.
Switch power supply on.
The instrument will go through a start-up sequence (LCD / LED test, software version, and initialization) and start the warm-up period. The display shows that the sensor will be ready for measurement in hh:mm:ss (countdown) and the instrument transmits the maintenance signal, see Section 10.3 on Page 41.
After the warm-up period, the instrument goes into normal operation. The display shows the current gas concentration, the selected gas and the units of measurement. The green LED is lit.
NOTICE
The correct date and time settings are important for many functions see Section 5.7.3 on Page 20.

4.1.1 Analog signals

The current output of the instrument during normal operation is between 4 and 20 mA and is proportional to the detected gas concentration.
Polytron 8000 uses different current values to indicate various modes of operation. The factory default settings are user adjustable for application specific requirements, see Section 7 on Page 34. This follows the NAMUR recommendation NE43.

4.1.2 The display and LEDs

In normal operation, the display shows the measured gas concentration, the selected gas and the unit of measurement. The green LED is lit.
The following symbols may also be displayed:
 " ", when the measuring range is exceeded  " - - - - " and " X " when a fault has been detected. The
yellow LED is lit, see Section 6.3 on Page 31.
"SIL", when SIL status is activated.
If the optional relay board is installed:
When the first alarm (pre alarm) has been triggered the red
LED blinks in single mode. The A1 relay is asserted.
When the second alarm (main alarm) has been triggered
the red LED blinks in double mode. The A2 relay is asserted. If the A2 is configured as acknowledgeable, and the A1 is configured as non-acknowledgeable, then, when an A2 alarm occurs, the red LED will blink in double blink A2 mode. After the alarm is acknowledged, the red LED will blink in single blink mode to indicate A1 is still active.

5.7 Settings instrument

5.7.1 Alarm settings

CAUTION
This function is only available if the relay module is installed.
With factory default settings and during normal operation, the relays are energized. This provides a “fail-safe” operation.
Switching the alarm On or Off
Select Settings > Instrument > Alarm > Alarm on/off.Select Enable or Disable and confirm.
CAUTION
If the alarm is set to Off, an alarm condition will not be shown by the LEDs or assert the relay!
NOTICE
The maintenance signal is transmitted and the symbol [ ] is displayed.
Configuring Relay A1 or A2
This function defines whether the alarm relay is energized during normal operation or energized at an alarm condition. If the configuration of the relay is set to “Normally energized”, the relay contact is asserted during normal operation and changes if an alarm is triggered. At a loss of power this will trigger an alarm (fail-safe). The fault relay is factory-configured to “Normally energized” and cannot be changed.
Select Settings > Instrument > Alarm > Relay A1 or
Relay A2 and confirm.
Select Normally energ. or Energ. on alarm and confirm.
Configuring Alarm A1 or A2
Latching means that once the alarm level is reached, the instrument will trigger the alarm. It will remain in alarm status even if the gas concentration subsequently does not meet the alarm condition any more. To clear a latching alarm it has to be acknowledged with [OK].
In non-latching mode, the alarm status clears if the gas concentration does not meet the alarm condition anymore.
Acknowledgeable means that the alarm relay can be reset before alarm condition clears.
Non-acknowledgeable means that the alarm relay can not be reset until the alarm condition clears.
NOTICE

Explanation of combining latching, acknowledgment and pre-acknowledgment of alarms:
Since the concepts of latching and acknowledgment can be confusing, the following six combinations are offered for clarification:
Latching and acknowledgeable
Latching and non­acknowledgeable
Latching and pre­acknowledgeable
Non-latching and acknowledgeable
Non-latching and non­acknowledgeable
Non-latching and pre­acknowledgeable
NOTICE
For safe operation:
The relays must be set to “Normally energized” and
the A2 alarm (main alarm) must be set to “latching” and “not acknowledgeable” or “pre­acknowledgeable”.

5.9.1 Sensor change

With this function, a sensor can be changed during operation without triggering a fault signal at the central controller. It also ensures that all sensor data in the microprocessor can be saved in the sensor memory (EEPROM) before disconnecting the sensor.
A sensor can be changed at any time. However, for safety reasons a fault alarm is generated when the sensor is disconnected until a new sensor is connected.
1. Select Settings > Sensor > Sensor change and confirm.
The maintenance signal is generated on the analog interface, the following display shows: “Please remove the sensor”.
2. Replace the old sensor with a new sensor, see Section 6.4 on Page 33.
When the new sensor is installed:
Display: “Loading data, please wait”.
When the sensor data are loaded:
Display: “Data loaded”.
3. Select Back to menu and confirm. The maintenance signal on the analog interface remains pending until the sensor is warmed-up.
The warm-up time depends on the type of sensor and its history. For example, if the sensor has already warmed-up on another instrument and the operation was only interrupted for a short time, the warm-up time can be shorter than the time specified in the Instructions for Use for the sensor.
Maximum warm-up time of a new sensor: see the Instructions for Use for the sensor.
NOTICE

6.1 Maintenance intervals

6.1.1 During commissioning

Check calibration.Check signal transmission to the central controller, LEDs
and triggering of alarm devices.

6.1.2 Every 6 months

Inspection by trained service personnel.
Check signal transmission to the central controller, LEDs
and triggering of alarm devices.
The maintenance intervals must be established for each
individual installation. Depending on safety considerations and application specific conditions the instrument is used in, these might need to be shortened.
Contact Dräger Service to contract regular calibration and
maintenance services.

6.1.3 Change sensor on demand

To change the sensor, see Section 6.4 on Page 33.

6.2 Calibration

Calibration of the instrument must be performed at regular intervals as detailed in the sensor data sheet.
General procedure
Attach the pressure regulator to the calibration gas
cylinder.
Fit calibration adapter to the sensor. The gas flow should be approximately 0.5 L/min.If the intended operation is at high altitudes, the reading will
be lower than the reading at sea level (reduced partial pressure). A new span calibration is recommended if the altitude or the ambient pressure is changed. The factory calibration is set to sea level.
Connect the tubing to the barbed fitting.
WARNING
Calibration gas must not be inhaled! See appropriate Material Safety Data Sheets. Calibration gas should be vented into a fume hood or to the outside of the building. For proper operation, never adjust the span before completing zero adjustment. Performing these operations out of order will cause the calibration to be faulty.
NOTICE
Calibration is not possible if the date and time are not set (see Section 5.7.3 on Page 20).
Dräger recommends calibrating instruments 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.
The sensor should be fully warmed-up (see sensor data sheet).

Sensor principle

8 Sensor principle

Dräger electrochemical sensors are measuring the partial pressure of gases under atmospheric conditions. The monitored ambient air diffuses through a membrane into the liquid electrolyte in the sensor. The electrolyte contains a measuring electrode, a counter-electrode and a reference electrode. An electronic potentiostat circuit ensures a constant electrical voltage between measuring electrode and reference electrode. Voltage, electrolyte and electrode material are selected to suit the gas being monitored so that it is transformed electrochemically on the measuring electrode and a current flows through the sensor. This current is proportional to the gas concentration. At the same time, Oxygen from the ambient air reacts at the counter-electrode electrochemically. The current flowing through the sensor is amplified electrochemically, digitized and corrected for several parameters (e.g. the ambient temperature).

NOTICE
The table shows the response of the sensor to other gases than the target gas (cross sensitivities). The listed values are typical and are valid for new sensors. The table does not claim to be complete. Gas mixtures can be displayed as the sum of all components. Gases with a negative cross sensitivity can cancel out a positive sensor signal. The influence of the O displacement is not taken into account (partial pressure measurement). Example: 2 Vol% ethylene in the air - cross sensitivity (table value) = -1 Vol% O

CAUTION
The exposure to higher concentrations of unsaturated hydrocarbons, alcohols or hydrogen over an extended period of time (dose approx. 100,000 ppm x hours) could cause the sensor to fail.

10.2 Marking

The marking is reproduced on a separate piece of paper shipped with the instrument.
Serial Number key: The third letter of the serial number specifies the manufacturing year: A = 2009, B = 2010, C = 2011, D = 2012, E = 2013, F = 2014, H = 2015, J = 2016, K = 2017, etc.
Example: Serial Number ARCB-0103: the third letter is C, which means that the unit was manufactured in 2011.
