Chapter 16 – Maintenance and Troubleshooting
Before carrying out any work on the equipment, you should be familiar with the contents of the
Safety Information section of this guide or the Safety Guide SFTY/4LM, as well as the ratings
on the equipment’s rating label. This should ensure that no damage is caused by incorrect
handling of the electronic components.
Before working at the rear of the unit, isolate all voltage and current
supplying it.
2.3 CLEANING
Before cleaning the device, ensure that all AC and DC supplies and
transformer connections are isolated, to prevent any chance of an electric
shock while cleaning.
Only clean the equipment with a lint-free cloth dampened with clean water. Do not use detergents, solvents
or abrasive cleaners as they may damage the product's surfaces and leave a conductive residue.
2.4 WATCHDOG
The RPV311 presents an internal watchdog algorithm. This algorithm verifies, every second, if the device’s
system is responding correctly. Case the system does not respond the device performs a hardware reboot
while the output relay 1 signals that the RPV311 is off.
