Auxiliary Input Power Connection Instructions:
1. Remove two Phillips Head screws on right side of
front panel of hinged door to access terminal strip.
2. Remove a plug button and install a box connector
to provide strain relief for the input power leads.
3. Use the appropriate size leads, at least 14 AWG –
2 wire with ground.
4. Using a flat-head screwdriver with a blade dimen-
sion of 0.137"(3.5mm) x 0.020"(.51mm), insert the
screwdriver into the square hole next to the mount-
ing hole to be used on the terminal strip. The
screwdriver should be inserted until it bottoms out.
This opens the screwless cage clamping style wire
insertion port. The insulation on the leads should
be stripped at least 0.25"(6.4mm). With the cage
clamp opened insert the wire into the round port
until it bottoms out. While holding the lead securely,
remove the screwdriver from the terminal block.
This closes the cage clamp onto the lead holding it
securely. Any open port on blocks #48, #49, and
#50 may be used.
5. The 4-terminal blocks, numbered #48, #49, and #50
are to be used to bring in auxiliary power. Terminal
block #50 is used for the input ground connection.
This terminal block is color-coded green and yellow
for easy identification. Terminal blocks #48 and #49
are to be used to connect the input power circuit.
(See figure A.1)
FIGURE A.1
Terminal blocks 48 and 49 are shipped connected to
CR2 and CR3 (532 and 531 leads) and these relays
are connected to the 3-pin and 4-pin connectors locat-
ed on the bottom of the POWER FEED™ 10A CON-
TROLLER. CR1 is available for a separate customer
connection, but it will turn ON and OFF with CR2.
Therefore, if Lincoln auxiliary equipment is to be used,
connecting 115Vac to the terminal strip is all that is
required to power the devices.
NOTE: The contacts of CR1 are not connected to ter-
minals #48 and #49 when shipped. Applying power
the #48 and #49 terminals will not transfer voltage to
the CR1 relay. Connect leads from the #48 terminal
to the #4 terminal and from the #49 terminal to the #3
terminal to supply power to the common contacts of
the relay.
Once input power is applied to the terminal strip, this
voltage is always on terminal strip blocks #3, #4 (if
connected), #11, #17, and #18. These are the inputs
to the solid-state relay contacts. Input voltage is also
present on terminal strip blocks #7, #8 (if connected),
#15, #21, and #22 due to the N.C. contacts on the
relays. When the CR1 relay is energized, input power
is transferred to terminal strip blocks #5 and #6 (if
connected). When the CR2 relay is energized, input
power is transferred to terminal strip block #13. When
the CR3 relay is energized, input power is transferred
to terminal strip blocks #19 and #20. CR1 and CR2
will be turned ON and OFF at the same time.
INTERFACING TO THE POWER FEED™
10A CONTROLLER
The POWER FEED™ 10A CONTROLLER is a versa-
tile controller. The Switch Panel can be removed and
made into a hand-held pendant. Most circuits can be
accessed through the screwless terminal strip. The
auxiliary relays can control standard Lincoln equip-
ment, or they can be used to control any other auxil-
iary equipment (see relay rating information above).
Custom controls or PLC interfacing to control starting,
stopping, motion, etc, can be accomplished with ease.
Converting Switch Panel to a remote pendant:
1. Remove all input power to the POWER FEED™
10A CONTROLLER including any auxiliary power
supplies.
2. Remove the fasteners from the Switch Panel and
disconnect the Switch Panel from the wire harness.
3. Jumper the wire harness connector (J2) to the mat-
ing 10-pin connector (P2P) that is floating inside the
control box (See Wiring Diagram).
