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.
Not applicable for Polytron
For safe operation according to TÜV 19 ATEX 8435 X the
instrument must remain in default alarm settings as listed
below.
– The relays must be set to Normally energ. and the A2
alarm (main alarm) must be set to Latching and Non-
acknowledgeable or Pre-Acknowledgeable.
– The A1 alarm (pre alarm) may only be set to
Acknowledgeable when it is used for triggering an
acoustic alarm device.

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.

Only for Polytron 5310 IR:
– The user must also read the Instructions for Use for
DrägerSensor IR, part number 9023981
1.6

During operation

– After modifying parameters with the PolySoft PC software
or another software, verify all parameters by downloading
from the instrument or by checking them on the Polytron
5xx0.
– IP ratings do not imply that the equipment detects gas
during and after exposure to those conditions. In case of
dust deposits and submersion/jet water, check the
calibration and the proper functioning of the device.
Risk of ignition of flammable or explosive atmospheres!
– CAUTION: High off scale readings may indicate an
explosive concentration.
(Only for instruments measuring combustible
atmospheres.)
– WARNING: Do not open when energized
®
Polytron 5200 CAT-specific:
– When exposed to a directed flow of air mixed with gas, the
measured values can be increased. See the
corresponding sensor data sheet for deviation values.

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.
