Startup: After switching on the supply voltage, the DF-7010 initiates 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 switches off.
Status signals: On SUPREMA operation, the adjustable status signals CALIBRATION and FAILURE
must be set to the following values:
Calibration —> 3 mA
Failure —> 2 mA
Cable defect —> 0 mA
Indication at the SUPREMA display: Signal error
Function test: Span gas application via: Integrated span gas inlet piece with 0.5 l/min,
(for standard test gases)
or test cap with 1.0 l/min, (Order No.: D6079762)
or splashwater-proof housing SG 70 with 1 l/min
or pump adapter PA 70 with 1.0 l/min
Calibration: New or modified calibration is made on the spot by means of the AUER CONTROL
operation module.
Operation manual AUER-CONTROL Order No.: 0792-124
Calibration demand of SUPREMA measuring points —> (INHIBIT/alarm suppression)
current output in calibration mode —> 3 mA
After confirmation, changeover to measuring operation.
Approved measuring components, calibrating conditions, measuring ranges, alarm
levels and linearisation tables see list of components: (Order No.: D0792420)
Possible other measuring components on request.
