Meech 233v3 User manual

Feature
Benefit
Extended pulse rate/frequency range (0.5 to
20
Hz).
Lower frequencies enable emitted ions to
travel
extended distances and thereby increase
the effective
range of static control. There is also greater
flexibility in
the positioning of bars.
Extended balance adjustment.
Finer, more accurate adjustment of ion
balance.
Through hole POT adjustment controls.
Prevents inadvertent adjustment by
operators after
installation set up.
Integral air connections supplied as
standard.
Easy, tidy connection of air supply pipe(s).
Built in alarm circuit with auto shutdown.
Detection of a fault in the ionisation system
results in
automatic shutdown, thereby preventing
serious damage
to the system.
Provision for remote alarm indicator and 24V
supply (through 8-way DIN connector).
Enables system installations to be monitored
from
remote locations. No additional external
power supply is
required to power remote indicators.
Provision for remote ON/OFF switching.
Allows system to be operated from remote
locations.
SSDC output option.
Provides tight balance in applications where
air flow is
required (e.g. Model 243ionising bar).
Light and compact.
Minimum space requirement.

INTRODUCTION
The Meech Model 233v3 Pulsed DC Controller has been designed to power any of
the Meech 200 series range of PDC products.
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
Model 233v3 Pulsed DC Controller
1. Locate the 233v3 controller in a convenient position near to the ionizing
product
to be powered from it.
2. Following the polarity indicators connect the grey HV plugs of the ionizing
product into the grey HV output sockets of the 233v3 .
3. Connect the 24VDC input supply ( see later) to the controller and switch ON.
The attached ionizer will now produce Pulsed DC ionization from its emitter
pins.

For Best Results
1. Keep target area clear and free from obstructions to ion flow.
2. Keep work area clear of all static generative materials.
3. Only use approved static control grounding methods and material handling
equipment.
Cleaning Instructions
Your Meech Pulsed DC Controller was designed to be virtually maintenance free.
1. Be sure the unit is switched off 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.

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 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

233v3 Pulsed DC Controller
Tests must be completed by a qualified electrical engineer.
If in doubt contact Meech head office or your local distributor.
CAUTION: While no danger to personnel exists, it is essential than any high
voltage ionizing equipment, (exception Meech Model 910 Water Resistant Ionizing
Bars), makes no contact with water or water based fluids.
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 ionizing 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 ionizing appliance be connected
to the power supply, these must be tested individually.
To check the Pulse DC system follow the procedure detailed below:
1) Switch off the electrical supply to the system.
2) Disconnect all ionizing 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 Opera-
tion and Maintenance manual.
If the 233v3 controller is found to be faulty please contact your local distributor or
Meech Meech Static Eliminators 330-564-2000 (800-232-4210).
