1. If the Micro is running, place any critical control processes under
manual control.
2. Remove power from the ControlWave Micro.
3. Remove the CPU module from the housing.
4. To remove the lithium battery, gently pry up the tab holding the
battery in the coin cell socket and remove the battery with a pair of
tweezers or needle-nosed pliers. Install the replacement battery.
5. Replace the CPU module in slot 2 of the housing.
6. Re-connect power to the ControlWave Micro.
7. Once the battery has been replaced, the unit executes its Flash-
based application (“boot project”) at power-up, but all of the
current process data is lost. At power-up, the Micro acts as though
it had just been booted and reverts back to the initial values
specified in its application.
5.2.7 Enabling / Disabling the Backup Battery
For maximum shelf life, the CPU module ships from the factory
with the installed lithium backup battery disabled. You must enable
it when you install the CPU module.
Enabling
To enable the battery, install jumper JP8 on pins 1-2.
Disabling
For maximum shelf life, you can isolate the battery from the circuit by
placing jumper JP8 on pins 2-3.
5.3 General Troubleshooting Procedures
This section presents some procedures to troubleshoot problems with
the Micro.
5.3.1 Checking LEDs
Most Micro modules contain light emitting diodes (LEDs) that provide
operational and diagnostic functions.
Table 5-1 shows LED assignments on Micro modules.
