5.3.2 & 5.3.3
Relay 1 and 2:
The contacts can be set as normally open or normal
-
ly closed with a jumper. See
.
The function of relay contacts 1 and 2 is 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
function.
When the relays are used as upper or lower limit switches, program
the following:
5.3.2.20
Parameter
: select a process value
Available values: Meas. value, Sample flow.
5.3.2.300
Setpoint
: If the measured value rises above respectively falls below
the set-point, the relay is activated.
Range: 0–250 FNU/NTU
5.3.2.400
Hysteresis:
within the hysteresis range, the relay does not switch.
This prevents damage of relay contacts when the measured value
fluctuates around the alarm value.
Range: 0–250 FNU/NTU
5.3.2.50
Delay:
Duration, the activation of the alarm relay is retarded after the
measuring value has risen above/fallen below the programmed
alarm.
Range. 0–7200 Sec
5.3.2.1
Function = Limit upper/lower:
