Connecting the instrument to a controller
from Dräger
NOTICE
i
i
For hook-up information, please refer to the
Instructions for Use which was included with the
Dräger controller (e.g. Regard, QuadGard).
Electrical connections at the controller
Connect the shield of the wires to the instrument earth ground
of the controller (e.g. chassis, ground busbar, etc.)
3.10 Connecting the instrument to a PC
The separately available IR interface connection kit (part
number 4544197) is intended for use with the Polytron 5100
and enables communication between the Polytron 5100 and a
PC using the PolySoft software.
3.11 PolySoft PC software (optional)
The PolySoft PC software is used to display instrument
information and edit configuration settings.
CAUTION
!
After modifying parameters with the PolySoft PC
software or another software, verify all parameters by
downloading
or
Polytron 5100.

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 remaining warm-up time is displayed in minutes.
t016
E.g.
means that the instrument will be ready for
calibration in 16 minutes and the instrument transmits the
maintenance signal on the analog output, see Section 5.3 on
Page 22. After the warm-up period, the instrument goes into
normal operation. The display shows the current gas
concentration and the units of measurement. The green LED
is lit.
All configurations must be checked, and the instrument must
be calibrated.
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.
Dräger Polytron 5100
by
checking
them
on
Polytron 5100 uses different current values to indicate various
modes of operation, see Section 9.3 on Page 27. This follows
the NAMUR recommendation NE43.
4.1.2
The display and LEDs
In normal operation, the display shows the measured gas
concentration and unit of measurement. The green LED is lit.
The following special symbols may also be displayed:
when the measuring range of the sensor has been
exceeded
when a fault has been detected the display toggles
between 'Err' and a number and the yellow LED is lit, see
Section 5.3 on Page 22.
If the optional relay board is installed:
when the first alarm has been triggered the red LED blinks
in single mode. The A1 relay is asserted.
when the second alarm has been triggered the red LED
blinks in double mode. The A2 relay is asserted.
If the A2 is configured as acknowlegeable, and the A1 is
configured as non-acknowledgeable, then, when an A2 alarm
occurs, the red LED will blink the double blink A2 mode. After
the alarm is acknowledged, the red LED will blink in single blink
mode to indicate A1 is still active.
