Alarm Low: If the measured value falls below the alarm low value,
the alarm relay is activated and E034 is displayed in the message
list
Range: 0–14 pH
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: 0–14 pH
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. 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 elec-
tronics housing. If the value falls below the programmed value
E014 is issued.
Range: -10 to +20 °C
Relay 1 and 2: The contacts can be set as normally open or
normally closed with a jumper. See
The function of relay contacts 1 or 2 are defined by the user.
NOTICE: 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
- End of Batch (relay 2 only)
2 Then enter the necessary data depending on the selected func-
tion.
Function = Limit upper/lower:
When the relays are used as upper or lower limit switches, program
the following:
Parameter: select a process value
