Failure indication X X
Open or Short Circuit Fault Indication:
X = Signal failure (FAIL-LED)
XX = Alarm LEDs, Signal exceeded, Signal failure (FAIL-LED)

Failure indication X X X
Startup: After switching on the supply voltage, the instrument initiales a self-test.
Ia = 3 mA (adjustable); —> After 5 minutes, the instrument changes over to measuring
operation. Ia = 4 mA
Explosion range: Before opening the terminal compartment, power to the measuring
head must be switched off.
Status signals: Calibration —> 3 mA ; Failure —> 2 mA: Cable defect —> 0 mA
Indication at the SUPREMA display: Signal failure
Function test: IR test filter
Calibration: Calibration demand of SUPREMA measuring points —> (INHIBIT/ alarm suppression)
current output in calibration mode —> 3 mA
After confirmation, changeover to measuring operation.
For approved measuring components, calibrating conditions, measuring ranges, alarm
levels and linearisation tables see list of components. (Order No.: 0770406)
Possible other measuring components on request.
