AMI INSPECTOR Oxygen
Program List and Explanations
A-96.250.701 / 140716
59
5.3 Relay Contacts
5.3.1
Alarm Relay:
The alarm relay is used as cumulative error indicator.
Under normal operating conditions the contact is active.
The contact is inactive at:
Power loss
Detection of system faults like defective sensors or electronic
parts
High case temperature
Process values out of programmed ranges.
Program alarm levels for the following parameters:
Meas. Value
Temperature
Sample Flow (if a flow sensor is selected)
Case Temperature high
Case Temperature low
5.3.1.1
Alarm Oxygen
5.3.1.1.1
Alarm High:
If the measured value rises above the alarm high
value, the alarm relay is activated and E001, is displayed in the
message list.
Range: 0.00 ppb –20.00 ppm
5.3.1.1.25
Alarm Low:
If the measured value falls below the alarm low value,
the alarm relay is activated and E002 is displayed in the message
list.
Range: 0.00 ppb –20.00 ppm
5.3.1.1.35
Hysteresis:
Within the hyst. range, the relay does not switch. This
prevents damage of relays contacts when the measured value
fluctuates around the alarm value.
Range. 0.00 ppb –20.00 ppm
5.3.1.1.45
Delay:
Duration, the activation of the alarm relay is retarded after
the measuring value has risen above/fallen below the programmed
alarm.
Range: 0–28‘800 Sec
