Control Adjustments
There are two adjustments that can be made on the 233v3 controller; BALANCE,
and RATE .
The BALANCE of positive and negative ion output can be adjusted to increase
polarity bias by simply turning the balance control towards either positive (right) or
negative (left).
When set to mVE or -VE the split is 20/80 - ie at maximum positive 80%
of the ions are positive and 20% of the ions are negative (or vice versa)
The RATE of pulse frequency can be adjusted from 0.1Hz to 20Hz..
The lower the
frequency (RATE) the greater the range (ie distance over which the ionization will
travel). A setting of 5 to 10Hz is recommended for most applications.
The purpose of these adjustments is to give total versatility to the positioning of
the ionizing product attached to it.
Remember it is important to verify calibration after any adjustments and before
using your ionizer around sensitive electronics.
Alarm
The alarm feature detects faults in the operation of the ionizing system, e.g.
problems caused by lack of product cleanliness. When a fault has been detected
the alarm LED will illuminate and the high voltage to the emitters will be auto-
matically switched off. If a single occurrence of a fault occurs, the controller will
switch off the HV for 1 second and then automatically reset. However, if the unit
detects 5 faults in 5 seconds the HV will be permanently switched off. The fault
must be removed ( e.g. by cleaning of the ionizing product) and the controller reset
by switching the mains supply to it OFF and ON.
A 7 way DIN socket is provided to mirror the alarm function to a central control
panel - see specification for connection detail.
LED Displays
The 233v3 has four indicator lights
1) Power light (Red)
- Illuminated when 24VDC supply
is provided to the unit.
2) Alarm light (Orange)
- Illuminated when unit has detected a fault and
has shut down.
3) Positive balance light ( red)
- indicates positive voltage and pulse rate
4) Negative balance light ( green) - indicates negative voltage and pulse rate
