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

5.3.2Head 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.
