NACOS Platinum
A flashing symbol for any alarm means that this alarm has not been acknowledged yet. A steady symbol
indicates an acknowledged status of an alarm, but that the cause for the alarm is still present.
An alarm can be of the following types:
State Symbol Explanation/Remarks
Normal - No errors in hardware/software and no limits exceeded
Device fail Error in the Control and Supervision system, the indication is invalid
Sensor fail The value received from the sensor is outside the legal limits
Manual Cut Out
Alarm function is switched off by the operator. Alarm will never occur
even if limits are exceeded. Manual Cut Out is normally not used for
Function Blocks
Event
Indication of an exceeded limit that shall not raise an alarm (Alarm
priority 4). This case is normally not indicated in the Mimic Diagram. In
some cases an indication for a binary input is displayed (e.g. Heater
switched on)
Alarm priority 3
Alarm with lowest priority. The alarm is indicated by a triangle (like a
traffic sign) in yellow. Inside the triangle the alarm priority is indicated
by the number 3, to improve readability for people with color blindness
(since prio 1 and 2 are also triangles)
Alarm priority 2
Alarm with middle priority. The alarm is indicated by a triangle (like a
traffic sign) in orange. Inside the triangle the alarm priority is indicated
by the number 2, to improve readability for people with color blindness
(since prio 1 and 3 are also triangles)
Alarm priority 1
Alarm with highest priority. The alarm is indicated by a triangle (like a
traffic sign) in red. (red is mandatory for highest priority alarm). Inside
the triangle the alarm priority is indicated by the number 1, to improve
readability for people with color blindness (since prio 2 and 3 are also
triangles)
Manual Set
Input from the process is disconnected in the software, and the value
is entered manually by the operator. In this case a blue circle is added
behind the actual alarm symbol, and for analogue values the font is
exchanged by a script font. For Function Blocks it is possible to make
"Manual Set" for both the alarm and the process feedback, so you may
have a blue circle behind the alarm icon and/or behind the state
symbol
