Output signals
Output channel 1:
The output channel 1 is used for the object temperature. To define it as alarm output, activate digital. With the
selection Normally open/ closed you can define the output as High- or Low-alarm.
Edit the threshold in the menu box Alarm to set the trigger of the alarm.
The source of output channel 1 can not be chosen – it is always TObj (object temperature).
The following analog outputs (if analog is activated) are available:
0-5 V
0-10 V
0/4-20 mA
Thermocouple (TCJ or TCK)
After you have selected the desired output (edit box: Output mode), you can adjust the temperature range of
the
IRtec Rayomatic 14
by pushing the button Adjust output slope.
Output channel 2:
This channel is normally used as output for the head temperature (THead), which equals the ambient
temperature. The source can also be set to TObj or TBox. The channel can also be used as alarm channel
(same procedure as output channel 1).
The Range can be switched between 0-10 V and 0-5 V – for analog mode and alarm mode (digital)
respectively.
Alarm 1 and 2 (Visual Alarms):
The alarms, set under Visual alarms are available via the optional relay interface board and as visual alarms
(change of color of the LCD backlight). The selection normally open/ close defines the alarm as High- or Low-
alarm. In Source you can choose between the signals TObj, THead and Tbox.
Both alarms will cause a color change of the LCD display:
blue:
alarm 1 active
red: alarm 2 active
green: no alarm active
In Appendix B you will find a table with all possible alarm combinations. The standard mode for the
visualization of the alarms can be reset with the button Standard visual alarms.
The button Blue backlight is a presetting to achieve a permanent blue backlight on the LCD display. Pushing
this button will cause the following:
both alarms will be set to normally open,
alarm limits will be set to the lower and upper measurement range limit of the connected
IRtec Rayomatic 14
,
Now alarm 1 is permanent active [blue] and alarm 2 is permanent inactive.
NOTE: All alarms (alarm 1, alarm 2, output channel 1 and 2 if used as alarm output) have a fixed hysterese of
2 K.
