Installation Instructions
These instructions will vary depending on the type of
unit you are replacing. They are general guidelines and
some system understanding will be needed to install
the CPC III. All of these steps need to be performed
with the vehicle shut-o󰀨.

2. Remove the primary control panel and bracket
that holds it to the shock mounts.
3. The CPC III Control Panel is pre-assembled.
Remove the faceplate and disconnect the local/
remote switch and display (Figure 2). Put the
faceplate to the side for later.

4. There are 4 holes provided to mount the CPC III
to the unit, two above the PLC and 2 below the
PDM. If your unit used the Mounting Plate and it
used the four holes on the far left and right, then
you may need to install the mounting panel to the
CPC III panel rst to match up the pattern.
CPC III Mounting Holes
Plate is only needed if the control
panel was mounted with these side holes.

5. Install the CPC III Control Panel to the shock
mounts using the old hardware.
6. Connect the four cables that match the CPC III
control panel decal (PPC, PRC, PFC, PBC). The
old Radio connector is no longer needed and can
be removed.

Scanreco Radio
1. The CPC III uses a Scanreco radio system similar
to current Schwing BPLs/TMPs. You can remove
all the old radio system components as none of it
will be used.
2. The Receiver and Antenna may be mounted any-
where externally on the unit. Mount the Receiv-
er/Antenna and run the three cables back to the
Control Panel. (Figure 5)

Oil Temperature Sensor
1. The Oil Temp Sensor that is installed on the unit
cannot be used. Locate the current Oil Temp
Sensor and replace it with the one provided.
2. Run the Oil Temp Harness from the Oil Temp
Sensor to the CPC III Control Panel and plug in
both sides. (See Item 260 on BOM 98458427)
Rear Control Panel
1. Remove the Rear Control Panel.

the rear gauges and replace the sensor with the
new CPC III sensor. If your unit did not have a
Concrete Pressure Sensor then you have the op-
tion of installing it to get additional functionality.
It is not required. (Item 280 on BOM 98458427)
5. Run the I/O-E harness from the CPC III Control
Panel to the CPC III Rear Keypad.

- One of the connectors you disconnected from
the Rear Control Panel will plug into the I/O-E
Harness (PIOC).
Note: On the early C32 rear panels, only one
connector was used. I this case PIOC will not be
used.
6. Connect the supplied connector jumper to the
remaining connector from the old Rear Control
Panel. (Item 60 on BOM 98458427)
Clean up the harnesses and nish securing all equip-
ment. (Item 270 on BOM 98458427)
Initial Setup
1. Turn on PTO but do not run the engine.
2. Turn on the Maintenance Switch. Inspect F9 fuse
in the PDM. If F9 fuse blows (or is already blown)
then nd the Quick Disconnect (PQD1) on the
harness located next to Cable C and disconnect
it. Tape the connector ends.
- Reset the circuit breaker by cycling the power.
- Turn o󰀨 the maintenance switch.

Important Notes
1. On some units the Agitator Forward and Reverse
buttons may be backwards. If yours is backwards,
swap the agitator forward and reverse connec-
tors at the valve.
2. All agitator forward and reverse buttons will need
to be removed from the unit as they will no longer
work. Use the rear keypad or radio remote.
3. If fuse F9 blows go to the initial setup instructions.
Fully test the system and Teach the boom using the fac-
tory login.
