SECTION 3—INSTALLATION OF COMPONENTS
WIRING
(continued)
b.
Install and wire the motor starter (unless one already exists or is installed in a custom control box) using black wire for the power, red and white
wires for the coil and interlock circuit, and blue for the motor forward connection to the control module.
If an existing starter does not have a 120-V AC coil, a new 120-V AC coil must be obtained, installed and wired in accordance with the
schematics provided before proceeding. An additional auxiliary normally open contact may also be required in the starter. (Do not run a separate
120-V line to the machine for operating the clutch/brake controls.)
c.
All necessary inputs and outputs to the control module are prewired from the printed circuit board terminals to the color-coded terminal strips for
installation. No wiring on the printed circuit board terminals is necessary.
d.
Run two black power lines (any two lines) from the load side of the disconnect switch (or from the line side of the motor starter) to the control
enclosure. Connect the two black wires to the proper terminals on the control transformer (see electrical schematic or transformer nameplate
for proper connections for different primary voltages).
Note: If a custom control box with a disconnect has been provided, this step is not necessary.
e.
Run a green ground wire from the incoming system ground to the control panel.
f.
Wire the motor starter and START/STOP controls according to the connection schematics.
Note: If a custom control box with a starter has been
provided, this step is not necessary.
g.
To wire the dual solenoid air valve, see the enclosed Installation Manual No. KSL-036 or KSL-037 and the wiring schematics. The exhaust air
muffler must be kept clean at all times. Never operate the machine unless the muffler is clean.
KEYPAD/DISPLAY
(See page 21)
The keypad/display can be furnished in a remote enclosure which is connected to the control module with a seven-conductor shielded cable that is
normally run in conduit or sealtite with other low voltage signal conductors (24 V or less).
This cable carries low voltage signals and should
not be located near or in the same conduit or raceway with conductors of higher voltage such as main power feeds or motor leads.
25’ of cable is supplied as standard and can be cut to length if required. Do not splice or interrupt signals. After connecting wires to the terminals on
the block provided, the cable should be plugged directly in to the control module terminal strip P4, as shown in the schematic prints that were sent
with the control box. Please contact Rockford Systems if a longer cable is required.
RESOLVER/PULSER ASSEMBLY
(See page 22)
The 40’ cable for the resolver/pulser assembly is shielded and can be cut to length for installation. It can be run in conduit or sealtite, or run loose.
This cable carries low voltage signals (24 V DC) and should not be located near or in the same conduit or raceway with wires for
higher voltages.
The cable connects from the resolver/pulser to the drive assembly, and should be wired directly in to the control module terminal
strip P5 as shown in the schematic prints that were sent with the control box. Do not splice or interrupt signals. Please contact Rockford Systems
if a longer cable is required.
AIR PRESSURE SWITCH(ES)
(See page 25)
Run
1
⁄
2
” nominal conduit from pressure switch(es) to the control box. Pull the appropriate number of wires through conduit. Number the wires
according to the diagram and connect to terminals at both ends. These pressure switches always use the normally open contact which is held
closed by normal air pressure. Loss of air pressure will open this contact and render the control inoperative. The normally closed contact provides
a signal to the user-programmable diagnostic inputs.
