6.8.1 Warnings / Alarms
The PLUS Master Control centralizes and reports warnings and alarms for all vacuum
pumps in the system.
In case of a warning or alarm on one of the PLUS pumps, a message appears in the sta-
tus bar of the PLUS Master Control interface (see
Bottom Bar [ ► 4] ). The icon of the
concerned pump is displayed in orange (in case of a warning) or red (in case of an alarm)
in the main screen (HOME) and in the screen of this specific pump (OPERATIONS >
PUMPS).

RUNNING WARNING
– Warnings are an indication that an operating parameter has exceeded the normal
threshold, but do not affect the operation of the vacuum pumps and the PLUS sys-
tem.
– Alarms are an indication that an operating parameter has exceeded the maximum
permissible threshold. In case of an alarm, the vacuum pump affected is automatical-
ly shut down by its local control system. However the PLUS system continues to op-
erate with the other PLUS pumps still in operation.
In the event of a warning or alarm, refer to the “WARNING/ALARM” menu in the con-
trol interface of the relevant pump and to the instruction manual of this pump for trou-
bleshooting and acknowledgement.
It is possible to de-prioritize vacuum pumps with active warnings in the PLUS system to
avoid the risk of an alarm or a failure, see
Settings [ ► 31] .
On the opposite, it is also possible to automatically acknowledge warnings directly from
the control interface of the PLUS Master Control by activating the "Auto warning ac-
knowledgement" button, see
Settings [ ► 31] .
