6.2.2 Front Panel Operation
6.2.2.1 Status LED
All CMS versions have a multi-colour indicator on the front panel, which is used to indicate the status or alarm
state. CMS-K versions also have a screen that changes colour. The alarm thresholds can be set from RMF-View via
the serial interface.
Figure 6.13 Front panel of K version (left) and Non-K version (right) CMS 2
Colour Shows
Green Indicates that the test result has passed, i.e. none of the alarm thresholds were
exceeded
Yellow Indicates that the lower cleanliness was exceeded, but not the upper one
Red Indicates that the upper cleanliness was exceeded
Blue Indicates that the upper water content limit was exceeded
Red/ Blue Alternating Indicates both cleanliness and water content upper limits exceeded
Violet Indicates that the upper temperature limit was exceeded
Red Flashing White Various fault codes can be indicated by the LED turning red and then flashing
white a number of times (Section 7.2.1)
Please note: If the codes seem confusing, note that a given colour will only ever be seen if the corresponding limit
has been specifically set by the user. So for example if a maximum temperature limit has not been set, the violet
indication will never be seen. If all that is wanted is a "green or red’’ light, that can be arranged by simply setting
only the cleanliness threshold maximum limit.
If the upper temperature alarm is set, this takes priority over the Contamination and Water alarms. In the event
of an over temperature condition, the LED will turn violet only, whether or not there is also a contamination or
water alarm condition. The rationale is that an over-temperature condition could be immediately catastrophic for
the hydraulic system.
