defined by the “dependence” parameter: the switching point is calculated by
adding a percentage “IN0” (from -100% to +100%) to the set-point of the
differential
(32) indicates the OFF switching point of the relay with respect to the point where the
ON switching took place. The OFF switching point is calculated by adding to the
ON point a percentage “DF0” (from -100% to +100%) of the differential.
Note: the default values of these parameters depend on the operating
mode and number of channels, as set out in the table below:

* The default values for mode 6 are the same as those of modes 0 or 1, depending
on whether the outputs are operating in direct or reverse.
• Due to alarms or malfunctions, the display of the measurement may alternate
with the display of messages describing the type of alarm.
The table below describes the alarm/error messages used.
Message Type of error
Output status
ER0
Sensor 1 disconnected or in short circuit
As parameter [SUA]
ER1
Sensor 2 disconnected or in short circuit
As parameter [SUA]
ALL
Minimum alarm
Depends on operating mode
ALH
Maximum alarm
Depends on operating mode
ALE
Outside input alarm
As parameter [SUA]
OFF
Regulation inhibited by outside input
As parameter [SUA]
Note:
the “OFF” message is not alternated with the measurement, but remains fixed
on the display
