Open or Short Circuit Fault Indication:
X = Signal failure (FAIL-LED)
XX = Alarm LEDs, Signal exceeded, Signal failure (FAIL-LED)
XXX = only alarms
XXXX = no change of indication
Startup: Presetting required —> before first calibration and when changing sensor
Presetting: Connect digital voltmeter to MAI card jacks.
Bridge current setting —> 310 mA
Zero adjustment by zero gas —> Zero setting to Ua = 400 ... 450 mV
Sensitivity adjustment with measuring gas —> Measuring range level
Ua = 1950 ... 2100 mV
or by means of the value of the existing gas concentration according to:
Ua (mV) = C (Span gas concentration in % of measuring range) / 100
*
1600 + 400
Warm-up period: 15 minutes for presetting
2 hours for calibration
Function test: Span gas application via: test cap with 1.0 l/min (Order-No.: 10049316)
Calibration: Calibration procedure according to SUPREMA operation manual
For measuring components allowed, measuring ranges, lower alarm levels and
conditions for calibration see list of components. (Order-No.: D0792420)
Possible other measuring components and measuring ranges on request.
