3 Operation of the Protec P3000
3.1 Start-Up
Assemble the Protec P3000 (see Section 1.5 ). Connect the mains cord and the
SL3000(XL) sniffer line, and then switch on the Protec P3000. The mains switch is
located on the rear.
The Protec P3000 will automatically start-up without operator interaction. After power
on the message "Wait for heater" will be displayed with the pump not being started
yet. The foreline pressure as well as the flow through the sniffer line will be stated
during this time.
After the pumps are switched on a self-test procedure will be performed during which
all hardware will be checked. The message "wait for sensor current" will be displayed
next. A bar graph will indicate the progress of this warm-up stage. The expected
warm-up time left will be stated below the bar graph.
Notice The start-up procedure normally lasts 2 - 3 min. After extended times of
power off, however, the start-up of the Protec P3000 may take up to 20 min.
max. To improve the start-up behaviour of the Protec P3000 after
extended times ofpower off, see Section
3.8 .
After switching on and completion of the run-up phase the Protec P3000 will be ready
to make measurements. There is no separate start function. The SL3000(XL) sniffer
lines are designed to maintain an inlet pressure low enough to make measurements.
Notice The Protec P3000 will only operate after having connected the sniffer line.
A calibration in accordance with Section 3.5 is recommended not before 20 minutes
after having switched on the instrument (warm-up phase).
