Parameter
Additionally, errors occurring are displayed as fol-
lows:
– Left-hand screen section: The symbol in front of the
component on which the error occurred is shown in
red in the tree view in the event of an alarm mes-
sage, and yellow in the event of a warning message
(fig. 68, item 4).
– Right-hand screen section: On the
Observation
in-
dex tab, the entire component and the specific pa-
rameter to which the warning or alarm applies is
shown in red or yellow (fig. 68, items 5 and 6).
– The multi-LED on the front of the CMC III PU is per-
manently red or orange.
– Depending on the settings, the alarm relay will
switch and the CMC III PU will emit an acoustic sig-
nal.
If the cause of an error message has been rectified,
the corresponding message may be automatically de-
leted from the message display. The status of the re-
spective component may also be reset, and all other
displays triggered by the error may disappear. How-
ever, this depends on the chosen alarm configuration
(see assembly and operating instructions of the
CMC III PU). In some cases, error messages and the
status may remain in the overview until acknowledged
with the "C" button on the CMC III PU (see section
9.2.2 "Acknowledging messages").
If the device configuration is permanently altered, e.g.
a new sensor is connected to the CMC III PU, this is
likewise output in the message display as an error
message, type "Alarm". Additionally, in such cases,
the multi-LED in the front of the CMC III PU will cycli-
cally flash green – orange – red. Such configuration
changes are not deleted from the message display
until confirmed by the operator (see section 9.2.2 "Ac-
knowledging messages").
Example: Increased temperature
If the temperature sensor integrated into the CMC III
PU measures a temperature above the value stored
as "SetPtHighWarning", a warning message will be
emitted.
In such cases, the display will change as follows:
– The symbol in front of the CMC III PU component in
the tree view will be coloured yellow.
– On the
Observation
index tab, the entire compo-
nent and the lines "Temperature" and "Status" will be
coloured yellow. The "High Warn" warning message
will also be emitted.
– A corresponding warning message will appear in
the message display.
If the temperature drops back below the "SetPtHigh-
Warning" value plus the hysteresis value (see
section 19 "Glossary"), the message may be automat-
ically deleted from the message display and the rele-
vant status displays reset, depending on the alarm
configuration (refer to the assembly and operating in-
structions of the CMC III PU).

Other displays
The operator's entries in the Web interface are auto-
matically checked against preset rules, depending on
the parameter entered. This means that changes can
only be saved if all values have previously been cor-
rectly entered in a dialogue.
