Introduction
The Meech Model 233v3 Pulsed DC Controller has been designed to power any of the
Meech 200 series range of PDC products.

4
Unpacking And Inspection
The Model 233v3 Power Supply was carefully packed at the factory in a container
designed to protect it from accidental damage. Nevertheless, we recommend careful
examination of the carton and contents for any damage. If damage is evident, do not
destroy the carton or packing material and immediately notify the carrier of a possible
damage claim. Shipping claims must be made by the consignee to the delivering
carrier.

How To Use Your 233v3 Controller
1. Locate the 233v3 controller in a convenient position near to the ionising
product to be powered from it.
2. Following the polarity indicators connect the grey HV plugs of the ionising
product into the grey HV output sockets of the 233v3.
3. Connect the 24VDC input supply to the controller and switch ON. A Mains lead
for the Meech switch mode power supply is provided. The mains supply to the
switch mode must be electrically grounded.
If using anything other than the Meech 24V supply please note the zero volt (0V)
must be electrically grounded (connected to earth).
The attached ioniser will now produce Pulsed DC ionisation from its emitter pins.

For Best Results
1. Keep target area clear and free from obstructions to ion ow.
2. Keep work area clear of all static generative materials.
3. Only use approved static control grounding methods and material handling
equipment.

7
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 maximum +VE 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 POT allows the pulse frequency to be adjusted. The rate can also be set
to SSDC mode; both the positive and negative outputs are on constantly. (See scale
on product label). In pulse mode the frequency can be adjusted from 0.5 to 20 Hz.
The lower the frequency (RATE) the greater the range (ie distance over which the
ionisation will travel). A setting of 5 to 10Hz is recommended for most applications.
When set to SSDC mode the e󰀨ective range of ionisation is up to 200 mm from the
ionising bar.
The purpose of these adjustments is to give total versatility to the positioning of the
ionising product attached to it.
Remember it is important to verify calibration after any adjustments and before
using your ioniser around sensitive electronics.

Alarm
The alarm feature detects faults in the operation of the ionising 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 automatically switched o󰀨. If
a single occurrence of a fault occurs, the controller will switch o󰀨 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 o󰀨. The fault must be removed (e.g. by cleaning of the
ionising product) and the controller reset by switching the mains supply to it OFF and
ON.
An 8 way DIN socket is provided to mirror the alarm function to a central control panel
(see specication 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

Cleaning Instructions
Your Meech Pulsed DC Controller was designed to be virtually maintenance free.
1. Be sure the unit is switched o󰀨 and disconnected from the mains supply.
2. The outside case may be wiped down with a soft damp cloth.
3. Let dry for a minute and turn back on.

Fault Finding
Tests must be completed by a qualied electrical engineer.
If in doubt contact Meech head o󰀩ce or your local distributor.
CAUTION: Whilst no danger to personnel exists, it is essential than any high
voltage ionising equipment, makes no contact with water or water based uids.
Should such an event occur, disconnect immediately and return equipment to the
manufacturer for water damage assessment. High voltage electrical equipment should
not make contact with water.
The Model 233v3 Power Supply and attached ionising products form part of a system.
To verify where a fault may have occurred it is important to test each item of the
system individually. Should more than one ionising appliance be connected to the
power supply, these must be tested individually.
To check the Pulsed DC system, follow the procedure detailed below:
1. Switch o󰀨 the electrical supply to the system.
11

2. Disconnect all ionising appliances from the controller.
3. Reconnect the supply and switch ON the unit.
4. Using a high voltage probe ( 1000:1 ) and meter measure the voltage on
each of the output sockets. The reading should be at Max. power 8 kV
5. If the controller is found to be functional, test each of the attached products
independently following the instructions detailed in the appropriate Operation
and Maintenance manual.
If the 233v3 controller is found to be faulty please contact your local distributor or
Meech Static Eliminators Ltd. ( Tel. [phone]).

Repair and Warranty
The Meech Model 233v3 Pulsed DC Controller is warranted by Meech Static
Eliminators Ltd to the original purchaser against defects in material and workmanship
for one year after purchase. Should any malfunction occur, please return the Ioniser
directly to us. All products returned to the factory MUST be accompanied by a return
authorisation number and must be shipped prepaid. For prompt service, ship the unit to
the factory with the return authorisation number shown clearly on the label. Be sure it is
well packed in a sturdy carton with shock absorbing material.
Include a note stating the nature of the problem as specically as possible, and also
include instructions for returning the Ioniser to you. We will pay one-way return surface
shipping costs on any repairs covered under the warranty.
Field repairs should not be undertaken during the warranty period. Repair attempts by
unqualied personnel will invalidate the warranty.
