Relay output
Active = Normally open contact (NO) closed
Trigger
If the preset trigger level is exceeded, relay contact NO will close and the relay contact NC
will open respectively.
Ready
As long as the Ecotec E3000 is ready for measurements, the relay contact NO is closed and
the relay contact NC is open respectively.

At “Settings > Interfaces” you make the settings for the interfaces.
2.2.1
Recorder outputs
For the recorder output the “Recorder Output Scale” and the “Recorder Output Gas” can
be selected.
The “Recorder Output Scale” can either be linear or logarithmic. The output signal is
provided through channel 1 (pin 1 of the I/O port).
Which of the 4 gases is indicated here is defined through the menu line “Recorder Output
Gas”.
Recorder output scale
Example:
The trigger level of the corresponding gas has been set to 3 g/a.
Material damage if load is high.
Wrong input voltage or current can destroy the unit.
►
Pay attention to the technical data of the relay outputs: Maximum load rating is
60 V DC / 25 V AC and 1 A per relay (resistive load).
LIN
The voltage range spans from 0 V to 10 V.
The leak rate which is output is normalized with respect to the trigger
level for the corresponding gas. The trigger level will correspond to an
output of 1 V. Higher and smaller leak rates may be output as a voltage
deviating by a corresponding factor with reference to the trigger level.
leak rate = 0.3 g/a

Voltages over 1 V indicate that the trigger level has been exceeded.
