Description

3.6 Limits

3.6 Limits
The SENTRON PAC3200 has a function for monitoring up to 6 limit values. These can be
monitored for violation of the upper or lower limit. If a limit value is violated, specific actions
can be triggered.
In addition, the limit values can be combined with each other using a logic operation. The
result of the logic operation can also be used to trigger specific actions in the same way as
the individual limit values.
The limit violations are shown on the display.
Defining the limit values
The following must be specified for each of the six limit values in order to define the limit
monitoring:
● Limit value monitoring ON/OFF
● Monitored measured variable
● Upper or lower limit violated
● Limit value
● Time delay
● Hysteresis
Combination of the limit values
