COSA Xentaur Hygrocontrol Type 86 Ex - Manual (Page 12)

3.1 Operational Mode „MEASURING"
As mentioned „MEASURING" mode is realized by :
- Code Switch „S1" in position „0"
- Jumper „X4" in position „M"
- Power is supplied to the transmitter
Now the instrument will detect values of temperature and relative
humidity and send them to the outputs. To inform the user of instruments
without display about this actual operation mode the LED’s „H2“ and „H4“
are lightened alternating.
3.1.1 Analogue Outputs
The standard version of the 86-EX instruments has analogue outputs.
Both types - current and voltage outputs - are provided.
Maximum load for the current outputs is 300 Ohms. Voltage outputs have
a inner resistance of 100 Ohms. Voltage and current outputs are short-
circuit protected. If a break or shortage of the sensors for humidity or
temperature is detected, the corresponding output will go 1-2 mA (or 1-2
V) over the upper limit or under the lower limit of the output, to signalize
the sensor defect to the user.
