3. Press down on the cover’s built-in top latch (with one hand) and
up on the cover’s built-in bottom latch (with the other hand).
4. Carefully slide the PSSM module out of the front of the housing.
If binding occurs, gently rock the module up and down to free it.
5. To replace a PSSM module, power must be off. Carefully align the
PSSM module with the guides for slot 1 in the Micro and insert
the module into the housing. When the module correctly seats, its
cover should latch to the housing.
6. Replace power and watchdog cables (and if provided the Display
Interface cable) and then apply power and test the unit.
5.2.5 Removing/Replacing an I/O Module
Use this procedure to remove or replace an I/O module.
1. If the Micro is running, place any critical control processes
under manual control and shut down the PSSM module.
2. Remove the applicable bezel (see Section 5.2.2).
3. Unplug local termination cable headers from I/O module
connectors TB1 and TB2 or remote termination cables headers
from connectors P3 and P4 and set the cables aside. Label or
otherwise identify these cables so you can easily return them to
their assigned connectors.
4. Press down on the cover’s built-in top latch (with one hand) and
up on the cover’s built-in bottom latch (with the other hand).
5. Carefully slide the I/O module out of the front of the housing. If
binding occurs, gently rock the I/O module up and down to free
it.
6. To replace an I/O module, power must be off. Carefully align the
I/O module with the applicable I/O slot and insert the unit into
the housing. When the module correctly seats, its cover should
latch to the housing.
7. Connect local termination cables to I/O module connectors TB1
and TB2 or remote termination cables to I/O module connectors
P3 and P4.
8. Apply power and test the unit.
5.2.6 Removing/Replacing the Backup Battery
Note: The CPU module draws power from the battery only if the
module loses power. For a ControlWave Micro containing 2MB
of SRAM, a worst-case current draw of 42 uA allows a battery
life of approximately 5238 hours. This means you should not
