Application and Use

The docking station DS220 is an automatic system for calibration and bump test of the gas detector
MICRO IV.

Positioning and Putting in Operation

Place the docking station on a hard level surface.
Make sure that the test gas is vented easily and without back pressure! Test gas supply is effected by

means of the pump built into the docking station.
When starting up make sure that the connections for gas inlet, gas outlet, pressure switch, mains supply

and PC connection resp. connection to additional docking stations are performed as shown in the picture
on page 3.

Handling

Use the green switch to turn the docking station on or off. When the docking station is turned on,
the switch is illuminated green.
The docking station allows the user to select between bump test or calibration. Use the red button for
selection. When the red button is lit, calibration is selected – otherwise you will do a bump test.

Bump test

The docking station allows up to 6 detectors to be tested simultaneously. The bump tests will start
automatically. Bump tests or calibrations can only be effected for MICRO IV detectors for the same gas
and detection range.
For detectors for a different gas or a different range you have to supply a different test gas, and the
parameters of the docking station have to be set accordingly by means of the configuration software.
When you put a detector in the docking station, the yellow LED flashes (approx. 10 seconds). During this
time you can add additional detectors to the other slots.
As long as the LEDs are lit permanently (test failed / test running / test ok), it is not possible to put in
additional detectors, as these would not be recognized.
The test results are signalized like a traffic light for every detector:

Once the test is completed (red or green LED), you should immediately remove the detectors and
replace them with other units. Further detectors can only be tested if checked units have been removed.

Yellow = Test running

Red = Detector faulty

Green = Detector ok

Extent of Bump Test

During the bump test the following parameters are checked:

 Time set
 Buzzer test
 Visual check / alarm LED
 Response time of sensor, response sensitivity
 Detector fault
 Time interval setting for next bump test, e.g. 14 days

Calibration

Use the red button to switch the docking station over to calibration. For calibrating the detectors, the red
button must be lit.
The docking station allows calibration of up to 6 detectors simultaneously. Calibration starts
automatically. Calibration is always possible for one gas only.
When a detector is put in the docking station, the yellow LED flashes (approx. 10 seconds). During this time
you can add additional detectors to the other slots.
As long as the LEDs are lit permanently (calibration failed / calibration running / calibration ok), it is not
possible to put in additional detectors, as these would not be recognized.
The test results are signalized like a traffic light for every detector:

Data Logging / Transfer to a PC

All information about bump test and calibration of individual detectors can be stored on a MMC card (if
fitted). Data transfer to a PC is effected automatically, if the docking station has been connected to the
PC (see page 3). The data can also be sent via a card reader without havi ng to connect the docking
station to a PC.

Test data to be stored both in the PC data base and on the MMC card:

 Serial numbers of detectors and of sensors
 Docking station ID
 Test mode: Calibration, Zeropoint, Bump Test
 Date and time
 Gas concentration
 Number of test gas bottle
 Bump test: Time (in ms) for alarm 1, Zeropoint: Display before adjustment, Calibration: Display

before calibration

 Bump test: Time (in ms) for alarm 2, Zeropoint: Display after adjustment, Calibration: Display

before calibration

 Zeropoint: Correction in mV, Calibration: Correction factor --- before
 Zeropoint: Correction in mV, Calibration: Correction factor --- after
 Buzzer ok, visual alarm ok, confidence bleep ON
 Battery capacity

Red = Calibriation failed

Yellow = Cal. active

Green = Calibration ok
