• The nc-contacts of the alarm relays (terminals 1, 4, 7 and 10) may only be used for
safety-related purposes if vibration loads cannot be avoided.
• When the “sensor-overload” message appears, the zero point and sensitivity must be
adjusted before using the device further. The device must be operated for at least 1
hour in pure air before this is done. The adjustment should checked regularly (e.g.
daily) until no further significant deviations are detected.
• The supply voltage at the connecting terminals of the GTR 210 must not be less than
18 V and not higher than 26 V
• The GTR 210 can be used only in the MED version on boats
• A usage of the transmitter on the boat bridge is not allowed
• The detection of oxygen on boats is not allowed
4.3 Commissioning
Commissioning is carried out after installation and following the electrical connection of the gas
transmitter:
• Switch on the supply voltage (switch on alarm control unit, e.g. FlexADOS 914).
A self-test takes place and the transmitter is initialised (see chapter 5.4). Once the self-test and
initialisation are complete, the warm-up period of the sensor starts. During this period, the sensor is in
maintenance-mode and there are no alarm outputs. Once the warm-up period has expired, the sensor
signal has stabilised. The transmitter is now in normal measuring mode.
Finally, the following initial checks must be carried out:
• Calibration check (see chapter 7.1)
• Check of signal transmission to evaluation unit (more detailed information on this can be found
in the operating manual for the evaluation unit used)
• Check of trigger of alarms
The gas transmitter is now operational.
