text: <s>[INST] Adding a timer to Powerflex 525 for maintenance intervals Summary: We want to track pump run timeWe want to add a timer to the pump ran by the Power Flex 525 that is controlling a Roots blower, Any ideas? [/INST] Parameter B019 in the basic display group is elapsed run time. You don't have to add anything at all; the drive keeps track. If you require an external elapsed time meter, the 525 has two relay outputs. Relay 2 on terminals R5 and R6 is already configured to be a running indicator (parameter T081 is set to value 2). If you need the opposite contact, then program relay 1 on terminals R1 and R2 to be the running indicator by setting parameter T076 to value 2. \\n </s>
