Alarm Saturation
Alarm High: If the measured value rises above the alarm high value,
the alarm relay is activated and E003, is displayed in the message
list.
Range: 0.00 –200%
Alarm Low: If the measured value falls below the alarm low value,
the alarm relay is activated and E004 is displayed in the message
list.
Range: 0.00 –200%
Hysteresis: Within the hyst. range, the relay does not switch. This
prevents damage of relays contacts when the measured value fluctu-
ates around the alarm value.
Range. 0.00 –200%
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
Case Temp.
Case Temp. high: Set the alarm high value for temperature of elec-
tronics housing. If the value rises above the programmed value E013
is issued.
Range: 30–75 °C
Case Temp. low: Set the alarm low value for temperature of electron-
ics housing. If the value falls below the programmed value E014 is
issued.
Range: -10 to +20 °C
Relay 1 and 2: The function of relay contacts 1 or 2 are defined by
the user
Note: The navigation in the menu <Relay 1> and <Relay 2> is
equal. For reason of simplicity only the menu numbers of Relay 1
are used in the following.
1 First select the functions as:
- Limit upper /lower,
- Control upwards /downwards,
- Timer,
- Fieldbus.
2 Then enter the necessary data depending on the selected func-
tion. The same values may also be entered in menu
