38 Agilent Restricted Agilent 5110/5100 ICP-OES Service Manual
3 General Information
Mains Power Module (MPM) Self Check
On
In this step of the MPM start-up sequence, all instrument control relays and output channels are
enabled and the instrument is considered to be “on”.
Flash at 2Hz in “on” state if open circuit was detected on heater and blower checks.
In addition to the above steps on the MPM start-up sequence, there is one further step entitled
“Shutdown”.
Shutdown
This step of MPM sequence operations is triggered when the MPM is called upon to shut down
the instrument, either by software command from the instrument control module; by user
operation turning off the soft-power switch; or through disconnection of the soft-power switch.
This step of operations is important in that it allows for the instrument control module to be
notified of the impending shut down of the instrument and in turn, to perform appropriate shut
down actions. The dwell time for the MPM in this step of operations is approximately 20
seconds and no comms on the SLIP bus for 15 seconds.
