8 Instructions for use | Dräger PointGard 2000 Series
en | Conventions in this document
Relay option
– Max 5 A current for relays allowed (SPDT contact 5 A at
230 VAC, 5 A at 30 VDC)
– At voltages >30 V AC or >42.4 V DC, the relay cables
must be enclosed in protective tubing, or double-insulated
cables must be used.
– The wiring for the optional relay module must be selected
and fused according to the rated voltages, currents and
environmental conditions.
– Voltage differences can cause insulation faults. Do not mix
electric loads with different voltage types (AC or DC).
Using DC loads, ensure that relay contacts only control
devices with the same DC voltage rating. Using AC loads,
ensure that relay contacts are only connected to devices
sharing a common phase.
1.5 Commissioning
– Ensure wiring for relays and connections for sensor are
made before applying power.
– Before leaving the instrument for normal operation, check
the configuration and calibration for the proper settings.
1.5.1 Calibration
– For proper operation, never adjust the span before
completing zero adjustment. Performing these operations
out of order will cause the calibration to be faulty.
– 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.
– Dräger recommends calibrating instruments with target
gas. This method 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.
– Methane and hydrogen should be calibrated with target
gas only and not calibrated with a surrogate gas.
1.6 During operation
WARNING
Risk of electric shock
Opening the instrument during operation can result in an
electric shock.
Disconnect power from the instrument and wait at least 1
minute before continuing.
1.6.1 Maintenance
– 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.
– Refer to the maintenance section in the transmitter
instructions for use.
Under normal conditions, Dräger recommends the following
calibration intervals1):
– Electrochemical sensors (EC): 6 months2)
– Catalytic sensors (CAT): 4 months

8 Calibration
A calibration checks and adjusts the measurement accuracy
with a known test gas concentration. First the zero point of the
sensor and then the sensor span is calibrated. Calibrations
have to be performed on a regular basis. The length of
calibration intervals depends on the ambient conditions in
which the sensor is operated.
Ambient conditions and aging cause sensor drifts. Sensor
drifts have a negative impact on the measurement accuracy.
Calibrations restore this accuracy. Depending on the severity
of the drift shorter calibration intervals have to be established.
To evaluate the ambient conditions of a new installations,
shorter calibration intervals with documentation of the drift
should be established. The plant operator should establish
customized calibration intervals with the obtained data.
8.1 Test gases
For test gas properties (e. g. humidity, concentration) refer to
the corresponding sensor data sheet.
Test gas humidity is irrelevant for O2sensors.
Depending on the type of calibration different test gases are
used.
Zero gas
Zero gas is a test gas to calibrate the zero point. If ambient air
is free from interfering impurities and measured gas, it can be
used as zero gas. For O2sensors, nitrogen (N2) is used.
Calibration gas
Calibration gas is a test gas to calibrate the sensor sensitivity
during span calibration. Calibration gas is a known
concentration of the measured gas diluted with clean air or
nitrogen. For O2sensors no calibration gas is needed, as
oxygen from ambient air is used.
8.2 Preparation of Calibration
WARNING
Health hazard due to test gas
Inhaling test gas may risk health or lead to death.
Do not inhale test gas.
Observe risks and security statements related to the test
gas (Refer to data sheets and instructions figuring on
calibration devices).

CAUTION
Triggering alerts by test gas
Applied test gas may trigger alerts.
Make sure that test gas is no longer applied after
calibration.
Prerequisites:
– Sensor has finished the warm-up phase
(6 Commissioning of the instrument).
– Date and Time are set (11.5 Setting date and time).
8.2.1 Preparing calibration set-up
See the following figure.
Calibration equipment:
– Dräger pressure regulator (1), for reactive gases use
stainless steel pressure regulator
– Dräger calibration adapter (2) (part number 68 10 536).
–Tubing(3)
– Dräger calibration gas cylinder (4)
Prepare calibration
1. Attach the pressure regulator to the calibration gas
cylinder.
2. Fit calibration adapter to the sensor.
3. Connect the tubing to the barbed fitting.
4. Enter the menu, see 7.6.3 Entering the menu
8.3 Gas flow for calibrations
Gas flow varies depending on the sensor.
Gas flow should correspond to the environmental conditions
during operation (e. g. duct measurement with higher flows
than 2 l/min)
8.4 Zero calibration
Ambient air can be used to zero the sensor instead of
Nitrogen or Synthetic Air only 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.
WARNING
Calibration fault at zero calibration
Insufficient ambient air flow may cause calibration errors.
Make sure that the ambient air flow to the sensor is
sufficient.
PointGard 2100 EC-specific:
For Oxygen (O2) sensors a zero calibration does not change
any value in the firmware or sensor. Thus, the zero calibration
function can be used to check the correct zero reading when
Nitrogen is applied to the sensor. The PointGard 2100 EC will
indicate a fault state if a zero check fails with a deviation of
more than 0.6 Vol% O2from zero. In case of a fault, repeat
the zero check or change the sensor if necessary. Use
Nitrogen (N2) for verification.
PointGard 2200 CAT-specific:
Sensors must not be calibrated with pure nitrogen. Catalytic
sensors need oxygen to work properly.
