11.6 Device Control
11.6.1 Output for the Target Temperature
The signal output can be set to 4 – 20 mA, 0 – 20 mA or mV. If current
output is activated, the output can provide a predefined current:
XO=4 output mode to 4 – 20 mA
O=13.57 output of a constant current at 13.57 mA
O=60 switches back to the temperature controlled output
11.6.2 Analog Output, Scaling
According to the temperature range of the model, it is possible to set
a maximum voltage/current value according to a temperature value
(e.g., the maximum current 20 mA shall represent 200°C / 392°F). The
same setting is possible for the minimum value.
H=500 the maximum current/voltage value is set to 500°C
L=0 the minimum current/voltage value is set to 0°C
Remark: You cannot set this value for thermocouple output. The
minimum span between the maximum / minimum settings is 20 K.
11.6.3 Alarm Output
The second output channel can be set in different modes, see section
5.3.2
Head Ambient Temp. / Alarm Output on page 20.
• Internal sensing head temperature
• Alarm output
K=7 internal sensing head temperature
K=4 alarm output for object temperature, 0 V in case of no
alarm
XS=125.3 threshold setting to 125.3°C (if U=C is set)
11.6.4 Factory default values
It is possible to reset the unit to the default values.
