6.3.3. Operator Checkout Procedure
The following checkout procedures test the major functions of the injector and should be completed before using
the injector for the first time or as a monthly routine preventive maintenance program. If a problem or a
calibration error is suspected, use this procedure for troubleshooting before contacting IMAXEON Service.
Certain steps in this procedure require that multiple observations be made during the test. Read through each step
for complete understanding.
If problems arise while going through these procedures, stop and do not use the injector. Record any messages
that are displayed. Contact your local Imaxeon Service Representative.
Checkout Procedure
1. Examine the injector for signs of damage or wear.
2. Disconnect the injector from the mains supply by removing the IEC mains connector from the base of
the unit.
3. With the injector off, disengage the circuit breaker marked CB on the base of the unit. Reengage the
circuit breaker noting the physical movement of the lever. Feel for any sign of difficulty in moving the
CB lever.
4. Connect an IEC power cord and connect to the mains supply.
5. Turn the mains rocker switch on the base to the ON position
6. The adjacent LED on the base of the unit will display green.
7. Press the ON switch on the injector head. The display should now turn on and the LED on the head will
turn green.
8. The screen display should be bright and clear when viewed front on.
9. Fit a new syringe.
10. Select the “?” button and allow the injector to find the syringe plunger
11. The injector should purge the air from the syringe automatically.
12. Using the manual fill control, touch the screen in the arrowed areas and observe movement of the piston
in or out depending on chosen directions.
13. Fill a syringe with an amount of water, say 120mL.
14. Press .
15. Program a routine protocol:
Volume = 100mL
Flow = 5mL/s
Pressure = 300 psi
16. Use a measuring cylinder or similar known volume container marked to 100mL (±2mL) volume.
17. Inject 100mL volume and observe the inject time to be 20 seconds (± 1 second) and the measured
volume is 100mL (±2mL).
18. Check the injection review screen displays an inject time of 20 seconds (± 1 second) and a delivered
volume of 100mL (±2mL).
19. Perform the 100mL injection again, but occlude the tubing by kinking or blocking the tube. Ensure that
the injection halts with an over-pressure or stall alarm.
Note: After performing this procedure before using the injector for the first time, the injector warranty
registration card should be completed, noting the checkout has been performed, and returned to Imaxeon.
