K=3 alarm output triggered by target temperature and internal sensor temperature, N.C.
normally closed
K=4 alarm output triggered by internal sensor temperature, N.O. normally open
K=5 alarm output triggered by internal sensor temperature, N.C. normally closed
K=6 alarm output triggered by target temperature, N.O. normally open
K=7 alarm output triggered by target temperature, N.C. normally closed
XS=125.3 sets the alarm threshold to 125.3 in current scale. The alarm threshold is used for the
target temperature only (see command XS). If the internal sensor temperature is
selected as the trigger source (K=4, K=5), use the command <DA> for defining the
alarm threshold.
10.9.3 External Input
The external input is shared by several functions, see section 7.4.3 External Input, page 44. The following
commands will change the input type automatically:
P=300, F=300 external input as trigger, resets the (advanced) Peak/Valley Hold function
ES=E external input as voltage input (0 V – 5 V) for setting the emissivity
AC=2 external input as voltage input (0 V – 5 V) for setting the ambient temperature
XL=T external input for On/Off switching of the laser
One of the basic rules for the used protocol here does forbid cross dependencies between commands.
So the user has to take care not to use two functions the same time. Using more than one function will
not destroy the device electrically but may result in malfunction.
?XT gives the actual trigger state
?TV gives the measured input voltage
10.9.4 Lock Mode
The access to the sensor is possible via serial interface or via direct user input on the control panel. With
a command it is possible to lock the mode buttons. This allows access to the sensor only via serial
interface.
