Setting relay trigger points
The relays of the transmitter turn ON/OFF when the CO
2
content
reaches the predefined trigger point. These points can be changed by
using the COM adapter (19040GM), a computer and a suitable terminal
software. There are two trigger points for both of the relays. The
higher limit activates the performance of the relay and the lower
deactivates it. The two limits are used to prevent the relay switching
back and forth when the measured value is very close to set point.
MF_Rx_HIGH yyy<cr>
where:
x = 1 or 2 (number of the relay)
yyy = trigger point (CO
2
content in ppm)
Example of setting the higher trigger limit of the relay 1:
>MF_R1_HIGH 1200
MF_R1_HIGH=1200.0000

NOTE
Remember to save the settings.
