1. AC POWER CORD
The
power cord is securely attached at the bottom center of the rear
of the unit and the cord will extend approximately 2.4 m (8 ft)
(not shown, but located on back of unit). 2. POWER
ON INDICATOR LIGHT
This
green indicator light will be illuminated when the power pack is
turned on. 3. ON/OFF/RESET
SWITCH (or BUTTONS)
This
toggle switch (or buttons, depending on the unit) turns on the internal
circuits of the unit and activates the power pack.
Proper operation is indicated by the digital and analog displays,
and either the "HI" or the "LOW" amperage range
indicator being illuminated.
This switch (or "ON" button, depending on the unit)
will reactivate the unit if it has tripped off due to an overload
condition. 4. DC
AMMETER
This
ammeter indicates the direct current being delivered by the power
pack to the output terminals and the plating tool.
The ammeter has a low and a high range and will automatically
switch between ranges when appropriate (see SPECIFICATION Section). Since the rate at which
metal is being applied is proportional to the rate of current flow,
the ammeter gives a second-to-second idea of the plating rate. 5.
HIGH/LOW RANGE INDICATOR
LIGHT
These
indicator lights, located under the ammeter, inform the operator
in which range the unit is operating.
High range is indicated by an amber light and low range is
indicated by a green light. 6. OVERLOAD
ADJUST CONTROL
This
is a current limiting device.
The current limiting feature enables the operator to pre-set
the power pack to shut down at any level below the maximum rated
amperage of the power pack and to prevent damage to parts from electrical
arcing. The unit comes
pre-set from the factory at the maximum amperage output of the power
supply (see OPERATION Section for further details). 7. DC
VOLT METER
This
meter indicates voltage available at the output terminals of the
power pack. 8. AMPERE
HOUR METER
This
meter indicates the amp-hr (amp x time) that have been passed and allows the control
of deposit thickness. This
LED meter is predetermining, which means it can be set to inform
the operator when the desired amp-hr have been passed (see OPERATIONS
Section for further information). 9. VOLTAGE
CONTROL
This
controls the dc output of the power pack.
10. FWD/REV
SWITCH
This
switch is used to control the output polarity of the power pack. This switch has a neutral
position, which will stop direct current from reaching the plating
leads. 11. DC
POLARITY INDICATOR LIGHTS
These
lights indicate the output polarity of the power pack. Forward polarity will be
indicated by a green indicator light and reverse polarity will be
indicated by an amber indicator light (in the neutral position,
neither light will be illuminated).
In addition, when operating in reverse polarity, an adjustable
reverse-current audible alarm will sound (see OPERATION Section
for further information). 12. OUTPUT
TERMINALS
Direct
current output terminals are color coded.
Connect output leads having the same color code
to each terminal. Leads
from the black terminal go to the part to be metallized or plated
and leads from the red terminal(s) go to the plating tool. |
