5.3.2 and 5.3.3
Relay 1 and 2:
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 identical. 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.
When the relays are used as upper or lower limit switches, program
the following:
5.3.2.20
Parameter
: select a process value
5.3.2.300
Setpoint
: If the measured value rises above respectively falls below
the set-point, the relay is activated.
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.
