4.4.2.3
Test the Ioniser Bar
The ioniser bar must generate an electrical field through a 180° arc, 120mm from the
emitter side of the bar and along its entire length. Use a non-contact volt sensor to test
the electrical field.
Before you start:
•
Make sure that the ioniser bar is clean (See Section 4.13.5).
Step
Action
Information
1
Turn on the MFC.
2
Do a check that the ioniser bar
emits a low electrical buzz.
If the ioniser bar does not buzz and
the transformer is good, the ioniser
bar is defective and must be replaced
(see Section 4.11.4).
3
Hold the volt sensor between the
emitter side of the ioniser bar and
the back panel of the gathering
area.
•
If no output is shown replace the
ioniser bar (see Section 4.11.4).
•
If a weak output is indicated
(50mm or below) replace the
ioniser bar (see Section 4.11.4).
•
If the output shown is not equal
(stronger at one end than the
other) replace the ioniser bar
(see Section 4.11.4).
4
Use a high voltage probe (1000 to
1) to measure the voltage across
the pins of the ioniser bar.
The voltage across the pins should
be approximately 6.5kV.
If the voltage measured is below
4.0kV replace the ioniser bar (see
Section 4.11.4).
