CHAPTER 15: MAINTENANCE
15.1 Firmware Updates
The QX products contain field updatable firmware to allow new features to be added to the product at a
later time. Firmware updates should only be performed when a new feature or correction is required.
Steps for updating the firmware:
1. Establish communication between Cscape and the controller using a direct serial connection to
MJ1.
2. Make sure your application is available on your PC or upload the application.
3. Make sure the machinery connected to the QX is in a safe state for firmware update (see warning
above).
4. Start the firmware update by selecting File | Firmware Update Wizard.
5. The correct product type should be selected, if it is not select the type of controller from the drop
down list.
6. Press the start button
7. Wait for the firmware update to complete.
8. If there is a communication failure check the cable, connections and comm. port setting and try
again.
9. Firmware updates typically delete the user applications to ensure compatibility. You will need to
reload your application.
10. Test the operation of the equipment with the new firmware before returning the QX system to an
operation mode.
15.2 Backup Battery
The QX contains an internal lithium battery used to maintain the real-time clock and retentive registers
when power is disconnected. The QX also contains a run-time battery monitor that continuously checks
the voltage of that battery.
Under normal conditions the battery in the QX should last 5 years. Higher operating temperatures or
variations in batteries may reduce this time. It is suggested that the battery be replaced at least every 5
years to assure backup operation.
13.2.1 Indications the battery needs replacing
The QX monitors the battery at power-up and run-time to provide the following indications when the
battery is low, failed or missing.
• At power-up, an error message is displayed for 2 second after the self-test indicating the low
or missing battery.
• The
Ok status is reset and the Battery indicator under the system menu diagnostic sub-
menu is set to WARNING.
• OCS register %SR55.13 is set.
Warning: Firmware updates are only performed when the equipment being controlled by the QX is in
a safe, non-operational state. Communication or hardware failures during the firmware update process
can cause the controller to behave erratically resulting in injury or equipment damage. Make sure the
functions of the equipment work properly after a firmware update before returning the device to an
operational mode.
