Installation Guidelines
The Controller CPU and Scanner modules may only be inserted into a dedicated slot location in the
rack. The modules are labeled on the LEFT side of the module: for example, C30, C50, C70, Scanner
1 Port (S50), Scanner 2 Port (S75) and Safety versions C30S, C50S, C70S, C75S, Scanner 1 Port
(S50S), Scanner2 Port (S75S).
Most of the components in an I/O expansion rack are identical to those used in the Controller Rack.
The Controller CPU is installed in the controller rack (Figure 1, item 3) whereas the Scanner 1 or
Scanner 2 is installed in the I/O expansion rack (Figure 2).

Controller CPU Installation Procedure
Follow the procedure in Table 1 to install a Controller CPU module in a controller rack.
Table 1 –Controller CPU Installation
Step
Action
1
Orient the controller rack to have the open side of the enclosure facing forward
with the power supply module located on the left and I/O module slots on the
right (See
).
2
Remove the Controller CPU module from its shipping container.
3
On the new CPU set/verify serial port switch settings.
Only one port may be a Modbus Master. It can be assigned to either port.
A small slotted screwdriver or paperclip works well; avoid using pencils because
their residue can damage the switch.

4
Insert the module into the dedicated slot location in the rack adjacent to the
power supply. Orient the module with module name at top. Align the module
printed circuit board with the card guide slots in the chassis. Press the CPU
module into the slot until the rear connector engages the mating connector of the
rack backplane. (See Figure 2)
Figure 2
5
Secure the Controller CPU module top and bottom with the captive mounting
screws. Torque settings 0,4 - 0,5 Nm (3.5 –4.4 Lb-In.)
6
Do not install the battery at this time. See instructions in the Controller
Installation and User’s Guide (document #51-52-25-154) for additional Controller
CPU setup information and battery installation.

Follow the procedure in Table 2 to install a Scanner 1 module in an expansion I/O rack.
Table 2 Scanner 1 Installation
Step
Action
1
Orient the I/O expansion rack to have the open side of the enclosure facing forward
with the power supply module located on the left and I/O module slots on the right (See
).
2
Remove the Scanner 1 module from the shipping container. Set scanner address for
the I/O rack using the switches on SW3. A small slotted screwdriver or paperclip works
well; avoid using pencils since the residue can damage the switch.
Switches 5, 6, 7, 8 must be OFF.
Only 1 switch position may be ON.
Switch 1 ON = Scanner 1
Switch 2 ON = Scanner 2
Switch 3 ON = Scanner 3
Switch 4 ON = Scanner 4

Controller CPU or Scanner 1 Replacement
Follow the procedure in Table 3 to replace a Controller CPU or Scanner 1 module in an existing rack.
Table 3 Controller or Scanner Module replacement
Step
Action
1
Before replacing the Controller CPU module verify a copy of the current configuration
file is available and a method of loading the file is understood. See Process Control
Designer User’s Guide or ControlEdge HC900 Control Station User’s Guide.
2
Remove power from the rack. (recommended)
3
Remove the screws that secure the module assembly to the rack.
4
Pull the assembly to remove. For Controller CPU modules, go to step 6.
5
Remove the Scanner 1 module from the shipping container.
Note: Verify module faceplate colour (Blue or Orange) matches the original faceplate.
Set scanner address for the I/O rack using the switches on SW3. A small slotted
screwdriver or paperclip works well; avoid using pencils since the residue can
damage the switch.
switches 5, 6, 7, 8 must be OFF.
Only 1 switch position may be ON.

Scanner 2 Overview
•One Scanner2 Module is installed in
each I/O Rack of a redundant system.
•I/O ports A –connects to CPU-A and
I/O Port B connects to CPU-B of the
redundant C75 Controller CPUs.
•Maintains communications with both
Lead and Reserve C75 CPU’s to
facilitate failover.
•Reads inputs from modules in rack &
writes outputs to modules in rack.
•Required for interface to C75
redundant controllers (cannot use
Scanner1 module with C75’s nor can
Safety be used with Non-Safety).
•May be replaced under power.
•Cannot use with non-redundant
systems.
Scanner 2 Non-Safety Scanner 2 Safety
Scanner 2 Installation Guidelines
The Scanner 2 module may only be inserted into a dedicated slot location in a Remote I/O Rack.

Scanner 2 Installation or Replacement
Follow the procedure in Table 4 to install or replace a Scanner 2 module in a redundant power rack.
Table 4 Scanner 2 Module installation or replacement
Step
Action
1
If you are installing a new Scanner 2, go to step 6.
If you are replacing the Scanner 2, go to step 2.
2
Remove power from the rack containing the Scanner 2 module to be replaced.
(recommended)
3
Remove the screws that secure the module assembly to the rack. Disconnect the A
and B IO cables noting cable to port assignment
4
Pull the Scanner 2 module to remove.
5
Remove the Scanner 2 module from the shipping container. Note: Verify module
faceplate colour (Blue or Orange) matches the original faceplate.
Position the scanner address switches on the module for the appropriate address
position (see Step 6).
6
Set rack address for the I/O rack using
the Scanner 2 Module switches on SW3
(shown at right).
(Scanner Address = 1 is shown.)
Switches 6-8 must be OFF.
Only 1 switch position may be ON.
Switch 1 ON = Scanner 1
Switch 2 ON = Scanner 2
Switch 3 ON = Scanner 3
Switch 4 ON = Scanner 4
Switch 5 ON = Scanner 5
A small slotted screwdriver or paperclip
works well; avoid pencils.
7
Insert the new module into the dedicated slot location in the rack. Orient the module
with the I/O ports on the bottom. Align the module printed circuit board with the card
guide slots in the chassis. Press the Scanner 2 module into the slot until the rear
connector engages the mating connector of the rack backplane.
8
