To Replace an SIO module:
1. Read all warnings on pages v and vi of this volume before replacing any
module.
2. If the control is running and on-line, use the system engineering workstation
to verify that the other CPUs and kernels are running without faults.
3. Switch the respective kernel’s CPU Reset Switch to its reset position (push
top of switch in).
4. Disconnect any communication cables from the SIO Module.
5. Unscrew the SIO modules captive-screw fasteners and release the module
from the motherboard connectors by pressing the top handles up and the
bottom handles down.
6. Remove the module by pulling straight out and place it into a conductive
plastic bag (Woodward P/N 4951-041)
7. Install the replacement SIO module by aligning the circuit board edge in the
card guides and pushing the module into the slots until the connectors on the
module and the connectors on the motherboard make contact.
8. With even pressure exerted at the top and bottom of the module’s front
panel, firmly push the module into place.
9. Tighten the two screws that secure the module in place (one at the top and
one at the bottom).
10. Reconnect the communication cables to the SIO module.
11. Switch the CPU’s Reset switch to its normal position (push bottom of the
switch in).
Termination Modules
The replacement of termination modules can be performed on-line (while the unit
is operational) or off-line (while the unit is shut down).
Caution must be taken whenever replacing a termination module on-line, or a
unit trip could result. The procedure used in the replacement of termination
modules on-line varies based on the control’s configuration and system wiring
configuration. Contact a Woodward representative to establish the correct
termination procedure to use based on your configuration.
To replace an Analog or Discrete Termination Module while the unit is off-line:
1. Read all warnings on pages v and vi of this Volume before replacing any
module.
2. Shut down the control.
3. Remove all power from the system. Do not attempt to replace a termination
module with the system powered.
4. Disconnect all ATM/DTM and field wiring.
