3.1Installation
To ensure overall system performance and effectiveness, the
selection of an installation site for the instrument is the most
important factor. Considerable thought must be given to every
detail of installation, particularly:
{
the local, state, federal codes and requirements 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 (e.g. Hawke A501/421/A/¾” NPT or
equivalent) see Section 8.1 on Page 24. 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. For correct tightening torques of conduit hubs,
plugs and sensor
{
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 7-12 mm.
When installed at locations exceeding ambient temper-
{
atures of 55 °C, use only appropriate wiring, specified
for at least 25 °C above the maximum ambient
temperature.
{ Strip wire insulation by 5-7 mm.
see Section 8.5 on Page 24.
Operation
Connect the wires as indicated in wiring figure in sec-
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 in
strument 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 8.8 on Page 25. The use of a reflecting shield is recommended.
The enclosure is weatherproof and suitable for outdoor installation. The use of the optional splash guard 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 8 on
Page 24.
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.

3.3Electrical installation with e-box
Installing this configuration is a two step process.
First, the e-box is mounted and connected to the field wires.
Second, the main instrument enclosure with the electronics
and sensor is attached to the e-box.
The e-box can be pre-mounted, wired and sealed with the supplied cover. Once the site is ready for commissioning, the
instrument is then hooked up to the e-box and taken into operation; avoiding that the instrument is damaged during the
construction phase.
The connection between the e-box and the main instrument is
realized via a ‘feed-through’. Depending on the instrument
selected, there are 3 types of feed-through.
{
3 wire for power (part number 4544182)
{
9 wire for power and relay (part number 4544169)

signal.
After changing the selected sensor, the instrument will
re-start.
When exchanging a sensor for a different type, the instrument must be calibrated.
3.7.20 LCD on or LCD off
This feature allows turning the LCD off in measurement mode,
effectively turning the Polytron 5000 into a non-display instru
ment.
The functionality of the instrument remains active, independently of the LCD state.
When in measurement mode and the LCD is set to OFF, pressing the Down arrow still gives complete access to the menu.
In case of an alarm, the red LED will blink. In case of a fault,
the yellow LED will lit and the display will toggle between ‘Err’
and a number.

4.1Calibration
Calibration of the instrument must be performed at regular
intervals as detailed in the sensor data sheet.
WARNING
!
Calibration gas must not be inhaled! See appropriate
Material Safety Data Sheets.
For proper operation, never adjust the span before
completing zero adjustment. Performing these operations out of order will cause the calibration to be faulty.
General procedure
1. Attach the pressure regulator to the calibration gas cylinder.
2. Fit calibration adapter to the sensor.
3. The gas flow should be between 0.5 and 2.0 L/min. At
higher altitudes, a flow greater than 0.5 l/min might be necessary (reduced partial pressure).
4. Connect the tubing to the barbed fitting.
NOTICE
i
i
In some cases (e.g. combustible vapors) a more accurate calibration can be obtained when the Dräger
calibration chamber is used instead of a calibration gas
cylinder.

Place the magnetic wand onto the sensor surface area
z
marked by and hold down for at least 5 seconds. The
display will change to a negative value (e.g. -10% LEL) as
long as the magnetic wand is held in place. This initiates
the auto-zeroing of the sensor.
Remove the magnetic wand. After 30 seconds, the sensor
z
will exit the auto-zeroing. As confirmation the display will
change again to a negative value (e.g. -10% LEL).
After this procedure the zero at the transmitter is adjusted for
eventual offsets.
4.1.1Zero calibration
1. Enter the function with OK.
2. Apply synthetic air or Nitrogen.
z
The display will show the current value blinking (e.g. ‘2’).
z
Wait for the value to stabilize.
3. Use the Up / Down arrow to adjust the value to 0.
4. Acknowledge with OK; the display will then jump back to
the main menu.
5. Turn off the gas flow and remove the calibration adapter
from the sensor, or disconnect tubing.
NOTICE
i
i
Ambient air can be used to zero the sensor instead of
Nitrogen or Synthetic Air if the area is known to be free
of the target gas or any gas to which the sensor may
be cross-sensitive (as listed on the sensor data sheet).
In this case, no cylinder or calibration adapter is
needed for the zero calibration.
4.1.2Span calibration
1. Check the set gas category (only for DSIR).
2. Enter the function with OK.
3. Apply span gas (e.g. 50 %LEL Methane).
The display will show the current value blinking (e.g. ‘48’).
z
Wait for the value to stabilize.

Alarm Hierarchy: A2 overrides A1 on the
LED. However, the A1 and A2 relays operate independently, i.e. if A1 is acknowledgeable, A2 is not, and the gas
concentration is such that it triggers A1
and A2:
Acknowledging will cause the A1 relay to
release. However, the red LED will still
double blink as long as the A2 condition
continues to exist.

Sensor principle
www.norrscope.com
6Sensor principle
6.1Operating principle for
DrägerSensor DD, LC
The DrägerSensor is a transducer for measuring the partial
pressure of combustible gases and vapors contained in ambient air. It uses the heat-of-combustion principle.
The monitored air diffuses through the sintered metal disc into
the sensor. The mixture of combustible gases and vapors are
catalytically combusted at a heated detector element (pellistor). The monitored air supplies the Oxygen required for the
combustion (must be greater than 12 Vol%). Due to the resulting heat-of-combustion, the detector element gets hotter. This
increase in heat causes a change of resistance in the detector
element, which is proportional to the concentration of the mixture of combustible gases and vapors in the monitored air.
In addition to the catalytically active detector element, there is
an compensator element. Both elements are parts of a Wheatstone bridge. Thus environmental effects like changes in temperature or humidity are almost entirely compensated.
6.2Operating principle for
DrägerSensor DSIR
The DrägerSensor IR infrared gas sensor is a gas transmitter
designed to determine the concentration of gases and vapors
in the ambient air. The principle of measurement is based on
the concentration-dependent absorption of infrared radiation in
measured gases.
The monitored ambient air diffuses through sintered material
into the flameproof housing of a measuring cuvette. The broad
band light emitted by the radiator passes through the gas in the
cuvette and is reflected by the cuvette walls from where it is directed towards the inlet window of a dual element detector.
One channel of the detector measures the gas-dependent light
transmission of the cuvette (measuring channel), the other
channel is used as reference. The ratio between measuring
and reference signal is used to determine the gas concentra
tion in the cuvette. The cuvette is heated to avoid condensation
of the atmosphere’s moisture content.
Internal electronics and software are used to calculate the concentration. As an output signal, the gas sensor emulates the
half bridge of a catalytic bead sensor.
6.3Contaminating gases for
DrägerSensor DD, LC
NOTICE
i
i
Certain substances in the atmosphere to be monitored
may impair the sensitivity of the sensors which are in
stalled in the sensing heads:
a) polymerizing substances such as acrylonitrile, butadiene and styrene,
b) corrosive compounds such as halogenated hydrocarbons (releasing halogens such as bromine, chlorine or fluorine when being oxidized) and halogen hydride acids as well as acidic gaseous compounds such
as sulphur dioxide and nitrogen oxides,
c) catalyst poisons such as sulphurous and phosphorous compounds, silicon compounds (especially
silicones), and metal-organic vapors. The sensors
used are based on measuring elements (pellistors)
which are “poison-resistant” (PR) and so have a longer
lifetime than conventional sensors if catalyst poisons
occur.
A calibration check might be necessary, if the sensor was exposed to a high concentration of combustible gases or vapors
for an extended period of time or to contaminants as listed
above.
7Disposing of the instrument
Disposing of electric and electronic equipment:
EC-wide regulations for the disposal of electric and
