Figure 5. Balance under < 10 volts.
When set under lab conditions, 5 volts
is attainable.
NOTE:
Each fan has its own balance
circuit, however the alarm circuits tie
them together. If one or more of the
individual fan balance circuits are offset
too much from the rest it could cause
the alarm not to function correctly. If
more than a slight amount of adjustment
is required at any individual fan zone,
we recommend that the unit be reset
using the "Major Reset Adjustment"
instructions below.

Major Reset Adjustments - Use this
procedure only if the "Balance
adjustment" above does not permit
proper operation.
1. Turn key to "SET" position.
2. The potentiometers in this unit have a
24-turn range. Reset all of them by
turning them at least 24 revolutions
counter-clockwise.
3. Set the fan adjustment pots (VR1,
VR2, VR5 and VR6) to center by turning
them 12 revolutions clockwise.
4. Center the "BAL" control found on the
control panel on the right end of the
ioniser using the following process.
Place a charge plate under any of the
fans, push and hold the + BAL switch to
find its most positive point, use the -
BAL switch to find its most negative
point, calculate the midpoint and set the
balance using the "BAL" buttons to that
point. Example: if the most positive
point is +40V and its most negative
point is -10V, you would set the balance
to ±15V.
5. Fine-tune each fan by placing the
charge plate underneath it and using it's
corresponding potentiometer to zero its
balance. Turn clockwise for more
positive and counter clockwise for more
negative.

6. Turn alarm sensitivity (VR4) 3
revolutions clockwise. Alarm center
(VR3) should be turned clockwise until
"PWR" light turns green. VR3 should
have two full revolutions in which the
"PWR" light remains green. If VR3
doesn't have two full revolutions of
green turn VR4 clockwise one turn and
check again. If VR3 has a lot more than
two full revolutions of green turn VR4
counter clockwise and check again.
Finish by setting VR3 to the midpoint of
green range.
