Can someone settle an argument about which colours should be used to indicate the state of a devices in a control system.
e.g. according th EN60204 10.3.2 for a circuit tripped on overload this is interpreted as an amber lamp for an abnormal condition, but I would prefer this to be red. The same as with an overtemperature trip.
Where a blocked filter is just a warning indication but does not cause a trip and is given the same colour, amber.
To me a trip requires a higher level of warning of indication and should be red.
Secondly when looking down a row of lights in a switch room the red ones naturaly stand out.
Is EN60204 being interpreted wrongly or have I got to the age where I should pack up me screwdriver and retire.
