1. Startup screen checks
Each time an instrument starts up, it goes through several checks to ensure it will run optimally. On the instrument screen, you should see the following picture (with green checkmarks):
If you do not see green icons at each check, the following list provides the most common solutions for each check:
Check -> Solution
Communication -> check cables
Instrument data -> check cables
Storage -> get new CF card and SW
Configuration settings -> restore setup file from one of the older setup files
Valves -> check cables
Chamber -> unlock chamber or service needed
Pump & Flow -> reconnect tubes or service needed
Device monitoring -> get new CF card and SW
2. Instrument status icons
The instrument status code number and the colored icon are shown on the Home screen. Pressing the colored icon opens a screen with the status interpretation.
(green) Normal operation.
(yellow) Warning. Instrument is still performing measurements, but there is/was an issue, that needs to be checked.
Solution 1: Calibrate flow – see video, or see User Manual chapter 9.3
Or
Problem 2: Clogged inlet line
Solution 2a: Check inlet lines, inlets
Solution 2b: Clean the sample inlet flow path:
Tools needed: Philips (‘ + ‘) screwdriver
Cleaning equipment needed: Ethanol, Cotton-tipped swab sticks, Cotton wipe cloths, Can of ‘dust removal’ pressurized spray with nozzle tube
Step 1: Turn OFF the instrument and unplug the power cord
Step 2: Remove the top cover and lock the optical chamber in the raised position
Step 3: Disconnect the inlet tube from the optical chamber. Use compressed gas to clean the flow path. Do not use compressed gas flowing from the main inlet port towards the chamber. Instead, always be sure that the flow of cleaning gas is in a direction AWAY FROM the optical chamber. This will prevent blowing contamination into the optical chamber.
To remove all particles from the main inlet, tubing, and ball valve, we recommend cleaning the airflow path with ethanol using cotton swabs – as shown in pictures below.
Step 4: Cleaning of the optical chamber (you may also refer to this video) and the flow divider:
Remove the transparent light guide cylinder and clean it with alcohol.
Remove the filter tape, cover the suction inlet ports (under the tape) with a wipe cloth and then blow the area clean with compressed gas.
Use cotton swabs (small, large) and ethanol for cleaning. Clean the vertical inlet tube fitting.
And the two flow paths:
Step 5: Preventive leakage test. We recommend that a leakage test should be performed once the instrument is operational: see video.
4. Instrument status codes 32, 48 – LED status
Problem: LED calibration warning (at least one channel OK – 500.000 limit on RAW values)
Solution (a): remove flow calibration pad
Solution (b): clean the optical chamber – see video.
Solution (b): update firmware
Solution (c): faulty LED board -> service needed
5. Instrument status code 64 – Chamber status
Problem: Chamber locked
Solution (a): Unlock optical chamber
Solution (b): Lubricate optical chamber sliders – see video.
6. Instrument status codes 128, 256 – Filter Tape status
Problem: Not much filter tape remaining
Solution: Schedule filter tape replacement. See video.
7. Instrument status code 384 – Filter Tape status
