Dräger Polytron 7000 Measuring Unit, Installation Instructions
Operation of the Dräger Polytron 7000 or Dräger Docking Station (Part No. 83 17 990)
requires full understanding and strict observance of the Instructions for Use of the
Dräger Polytron 7000!
Dräger Polytron 7000 Measuring Unit – Installation
Remove the rain cover from the previously installed docking station.

Examine seal for signs of dirt and clean if necessary.

1 Check position of eccentric catches and correct if necessary. The eccentric
opening must point upwards, engaged position.
Use only a 5 mm Allen key without a ball head.
Check the polarity and cable routing and check that the connector is securely

seated; rectify as necessary (see the installation notes for the Polytron docking
station).
Unpack the Dräger Polytron 7000 measuring unit.

Setting the switch for the backup battery
Check the position of the switch on the bottom of the unit.

This switch must be set to "on"; otherwise, the time, date and data saved in the
Datalogger and the Event Logger will be lost in the case of a power failure.
2 Insert the measuring unit about halfway up the docking station and slide it in as
far as it will go.
3 Lower the unit along the front edge of the docking station. About 5 mm before its
hits the stop, the resistance will increase as the connector engages with the
socket on the printed circuit board.
Check that the terminals in the docking station are correctly aligned if the con-
nector does not engage correctly!
Ensure that the front bottom of the measuring unit is flush with the bottom of the
Docking Station. Apply pressure to the measuring unit until it "clicks" into place.
If the fronts are not flush, the measuring unit is not completely sealed and could
get water inside the transmitter!
1 Turn the eccentric catches clockwise with an Allen key to lock the measuring unit

( = approx. 180°).
Then insert the sensor as follows:
4 Remove bayonet ring from transmitter; remove cover plate.
Remove sensor from packaging.

Remove the short-circuit strap from the sensor (if it is fitted).

There is a coded connector on the back of the sensor. Place the sensor in the

opening with the connector at the back and the Dräger logo at the front.
Before plugging the connector in the socket, ensure that they are identically cod-
ed. Incorrect connection can damage the sensor!
Secure sensor in transmitter with bayonet ring.

If necessary, calibrate the sensor.

If pre-calibrated sensors are used, the alarm chain must be tested with, for ex-

ample, the bump test.
