User manual

There is no special maintenance procedure for CyBro family. There are no spare parts that you can
change yourself. In case of malfunction, you should contact local distributor.
A routine maintenance check (about every one or two months) of PLC and control system is good
practice, and should include the following items:
air temperature - check the ambient air temperature in the control cabinet, so the operating
temperature range of any component is not exceeded.
air filter - if the control cabinet has an air filter, clean or replace it periodically as required.
fuses or breakers - verify that all fuses and breakers are intact.
air vents - verify that all air vents are clear, allowing air to circulate for cooling.
