The functions can be enabled and disabled with theOperation setting. The corresponding parameter values are “On” and “Off”. Theoperation counters are cleared when Operation is set to “Off”.The operation of the functions can be described by using a module diagram. All themodules in the diagram are explained in the next sections.1MRK 502 034-UEN - Section 13Monitoring431Technical Manual
