5.4.1. Value assigned to output relay
None, relay is still off
Temperature at °C
Relative humidity
Computed value
(dew point temperature)
Barometric pressure
Binary input 1, input 2
and 3 similarly
far condition 0
far condition 1
FAR0
–
„
far condition
0“: after device’s power on the relay is open
FAR1
–
„far condition
1
“: after device’s power on the relay is close
If “far condition” is assigned to output relay, then there is possible to change the output relay status
by Modbus communication protocol only. See chapter
at page 18.
5.4.2. When close output relay
High limit „HI“
–
the relay closes when measured value exceeds preset
„high limit” for longer
time than preset
„
delay time
“
. Relay goes open when measured value decrease under
„
high limit
“
value minus the
„hystere
sis
”
value. See example.
