ground/return is on the outer two conductors.
The minION2 may also be powered through the plug type terminal block locat-
ed on the rear panel; +24 VDC goes to pin 1 and the ground/return goes to pin 2.
This allows powering of minION2 ionized air blowers from a 24 volt machine
bus. Each minION2 draws 250 milliamps so adequate current must be provided.
A unit powered through the plug type terminal block may power other minION2
units wired in series (daisy chain fashion) with the 4P4C modular cords includ-
ed. Power distributed through the modular cable must be limited to a maximum
of 2 amps for safety purposes. Wired in this fashion, the recommended maxi-
mum number of units wired in series is 5.
The plug type terminal block also provides relay contact output for the fault
alarm. Pin 4 is Common. Pin 5 is Normally Open. Pin 3 is Normally Closed.
The relay contacts are rated for a maximum of 1 A at 30 Vdc resistive with a
maximum switching voltage of 220 VDC.
A terminal block plug is supplied with the minION2.
SECTION 6 Operation
The minION2 power switch is located on the rear panel of the unit, above the
modular cable jacks. The rear panel also has a small hole next to the modular
cable jacks that provides access to the recessed fan speed control adjustment.
The fan speed may be adjusted with a small screwdriver or trim pot tool.
Clockwise rotation provides maximum fan speed, counterclockwise provides
minimum fan speed.
The front panel of the minION2 has two LED indicator lights. The green LED
indicates the unit is powered. The red LED is a fault indicator for the high volt-
age power supply monitoring circuit. The high voltage power supply monitor-
ing circuit also drives the fault alarm relay.
The minION2 produces an ionized air stream that covers a targeted area. The
time required to neutralize a static charge on an item in the target area depends
on several factors. Two important factors are; distance to ionizer and air veloci-
ty. Set the fan speed as high as acceptable to provide more rapid static neutral-
ization. For fast neutralizing, the minION2 should be as close to the target area
as practical.
SECTION 7 Maintenance
7.1 Emitter Cleaning
To clean emitters, turn off the minION2 and unplug it from the power supply.
Visually inspect the emitter array for particle or dust accumulation. Moisten a lint
free swab with deionized water or isopropyl alcohol and insert it through the inlet
grille. Wipe each emitter clean and clean the emitter hub as necessary to remove
accumulation. Allow to evaporate completely before returning the minION2 to
service.
7.2 Air Inlet and Outlet Cleaning
The air inlet grille on the rear of the unit and the ionized air outlet should remain
clean to prevent restriction of air flow. They can be cleaned with a soft brush or
vacuum.
