8.4 Device Control

8.4.1 Output for target temperature

The output can provide a predefined value of full analog range when signal
output is 0 ... 5 V.
?XO Request for the output mode
O=25 output of a constant voltage at 1.25 V (25% of 0 ... 5 V)
O=255 switches back to the temperature controlled output

8.4.2 Analog output, scaling

According to the temperature range of the model, it is possible to set the
maximum voltage value according to a temperature value (e.g., the maximum
voltage 5 V shall represent 200°C). The same setting is possible for the
minimum value.
H=500 the maximum voltage value is set to 500°C
L=0 the minimum voltage value is set to 0°C
You cannot set these values for thermocouple output. The mini-
mum span between the maximum / minimum settings is 20 K.

8.4.3 Alarm output

The alarm output can be set to N.C. (relay contacts are closed while in home
position) or N.O. (relay contacts are open while in home position). The alarm
output can be activated by:
Internal sensing head temperature
Target temperature
K=0 alarm output disabled
K=4 Sensor head ambient temperature lower than threshold, relay
N.O.
K= 2, XS=125.3 Target temperature lower than threshold, relay N.O.,
threshold setting to 125.3℃(if U=C is set)
