Acknowledging messages

(see page 106).
Acknowledged messages remain in the

that the cause for the message has been
removed.
■ Messages cannot be acknowledged in
message history but only in the "Fault
messages" display.
■ Messages can only be acknowledged
together.
■ Required resistance curves for testing
sensors, see page 168.
