Eventide ARGUS 3000 - Check the Operating Voltage

17. DO NOT secure the rear cover in place at this time.
18. Gently insert the database board into the enclosure slot and apply pressure until the board engages
the rear connector and the handle is flush with the bezel. The CPU board must be held in place or
the database board will push it out the back of the unit. Make sure the database connector is fully
J seated.
19. Tighten the two phillips-head screws to secure the database board into position.
L< 20. Position the bottom panel in place and secure it with the eight flat-head screws (six 3/16 inch and
two 1/8 inch). Be sure to replace the red-marked screws in the positions noted previously and
j | depicted in Figure 5 on page 16. The two red screws are attached to the front panel bezel. (The
LJ rear cover screws are not replaced at this stage.)
j I 21. At this point, it is recommended that you check the operating voltage on the daughter board. Follow
LJ the steps given in Sub-section 8.4 for checking and adjusting this voltage. Then continue with the
final steps below.
J 22. Secure the rear cover in place with five flat-head screws.
i 23. Secure the top panel in place with 10 flat-head screws each.
24. Apply power to the unit and verify that the unit passes all of its self tests. If an error results during
I , the self-tests, or if the unit fails to power on, refer to Section 4 of this manual.

8.4 Check The Operating Voltage
|
° All boards must be in place to check the voltage. The rear cover of the Argus must be removed to expose the
potentiometer on the daughter board.
^ To operate correctly, the Argus should be operating at +5 volts (+0.05 volts). This voltage may need to be
adjusted after the daughter board is replaced. All boards must be installed in the unit, and the unit must be
I I powered on before its voltage can be tested.
WARNING
^J The high voltage wire carries 8000 volts! Do not apply power to the unit while the high voltage
wire is exposed. If there is high voltage leakage in the unit and you accidently touch the high
j j voltage wire, serious injury could result.
LJ
Necessary Tools: Small phillips head screwdriver
j | Digital voltmeter (to check the unit's voltage)
^ Very thin flat head screwdriver
