Introduction

For your Safety

In accordance with § 3 of the German Equipment and Product Safety Act (GPSG), this manual describ es the
intended use of the product and serves to avoid danger. It must be read and observed by all persons who
operate, servic e, maintain and inspect this product.

This detector can serve its intended purpose only if it is operated, serviced, maintained and inspected
according to the instructions given by GfG Gesellschaft für Gerätebau. The warranties given by GfG
Gesellschaft für Gerätebau mbH will be voided if the product is not operated, serviced, maintained and
inspected in accordance with GfG’s instructions.

The above does not alter statements regarding warranties and liabilities in the General Conditions of Sale
and Delivery of GfG mbH. Repairs may only be carried out by skilled or trained persons. Modifications and
changes to the product may only be carried out with the approval of GfG mbH. Unauthorised modifications
to the product result in the exclusion of any liability for possible damage. Only genuine GfG accessories may
be used together with the produc t. O nly spare parts approved by GfG mbH may be used for repa ir work.

Note: When using the docking station you have to remember that all gas detectors that are calibrated with
the station will be influenced. Incorrectly entered test gas concentrations will result in all gas detectors being
incorrectly cali b r a ted.

Application and Purpose

The Docking Station DS404 is an automatic test station with four test gas ports for carrying out function
tests ("bump tests") and for calibration of the zero point and sensitivity of the sensors of the Microtector II,
Microtector II I und Polytector III series gas detectors.

Installing and Connecting the Docking Station

During commissioning, the hoses and leads for fresh air supply, test gas
supply, gas discharge, pressure switch, mains power supply and PC
interface or interface to a further docking station must be connected to
the test station.
The docking station must be installed on a firm and even surface. The
gases must be supplied pressure-free. For direct gas tapping from test
gas cylinders, use the gas connection fittings listed in section
"Accessories and Spare Parts". During operatio n, the gas is drawn in by
the pump of the docking station. Ensure also that the test gas can leave
the docking station freely without pressure! If CO
tested or calibrated using the docking station, a CO
should be installed in the fresh air supply line (see chapter CO
absorption filte r ).
Ensure that the plug is installed on the T-piece of the fresh air supply
line or that it is conn ected to a further doc king station.
Up to two DS404 or three DS400 docking stations can be operated with
one DS400-PS1 power supply u nit. For this the DS404 or DS400 have to
be connected together using a double-sided jack plug.
During commissioning, the connections for gas supply, gas discharge,
pressure switch, mains power supply and PC interface or interface to a
further docking station must be made as shown in the figure in the
following chapter.

This corresponds to a service life of approx.

minutes of

calculates the service life on the basis of the flow rate and gives a
warning to replace the filter in good time. The filter gradually

As water is also produced during the absorption process due to the chemical reaction, depending on the CO2
content of the air, this can have a min or influence on the setting of the sensor z e r o point.

Handling

The docking station is operated by means of the control ke ys of the gas detecto r . The status and tes t data
are output to the detector display . If a gas detector is inserted in to the docking station, the "Information",
"Function Test" or "AutoCal adjustment" options c a n be selected via softkeys on the gas detec tor.
Microtector II d evices can remain in the docking station for operation. De vices of the Microtector III and
Polytector II I s e r ies must be briefly rem oved from the ch a r g er to select the displayed operating opti ons, in
order to be able to operate the concealed keys. After pressing th e keys, the unit is placed back in the
charger. Under certain conditions, a "Firmware Update" can also be carried out using the docking station
when the gas detector is in the station . For this, there m ust be a newer version of a corresponding update
file on the SD card and the "Update" started by pressing the cor res ponding key.
In order to charg e a gas detector, it must be s witched off and placed in the docking s ta tion. If the detector is
placed into the docking station switched on, the necessary test or calibration will be started automatically
after 10 seconds. Within the 10 seconds you can override the automatic selection and start a function test or
calibration man ually.
