IOUT 2

The measured air temperature or a status as configured in Status limits in can be returned as an analog 4…20 mA signal on pin 7 of the MAIN connector.

If the air temperature is selected as output, the span is set to 100 °C and the offset to -40°C as default.

If one of the status options is selected and the conditions specified in Status limits are satisfied, the output is set to high (20 mA) and otherwise to low (0 mA). The following status options are available:

ID

Option

Description

1

off (default)

IOUT2 is inactive.

2

value, temperature

The air temperature is returned.

3

status, level limit

If the level exceeds the limit specified in Level limit, 20 mA is applied, otherwise 0 mA.

4

status, snow settling

If the USH-9 detects a snow cover 20 mA is applied, otherwise 0 mA. A snow cover is detected if Snow settling, strength drop exceeds the specified limit and Snow settling, maximum level is not reached.

5

status, snowfall

If the USH-9 detects snowfall 20 mA is applied, otherwise 0 mA. Snowfall is detected if Snowfall, precipitation limit is exceeded and the temperature is below Snowfall, max. temperature.

6

status, all limits

If any limit mentioned above is violated, 20 mA is applied, otherwise 0 mA.
