5.3.2 and 5.3.3 Relay 1 and 2: The contacts can be set as normally open or nor-
mally closed with a jumper. See Relay Contacts 1 and 2, p. 23 . 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
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.
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.
