Parker Hannifin vm24 manual Series Controller/Indexer, Outputs

6000 Series Controller/Indexer

First, verify that 6000 Series Controller/Indexer I/O is functioning properly to aid in isolating the problem. Disconnect the 50-pin ribbon cable, or just disconnect the cable from connector J4 of the VM24, before performing this test.

Outputs:

Use the Transfer Output Status (TOUT) command to check the status of the outputs. Use the Output State (OUT) command to change the outputs. Use a voltage meter to check individual outputs at the I/O connector of the 6000 Series unit to verify that the voltage level toggles between Ground and Vo.

Inputs:

Use the Transfer Input Status (TIN) command to check the status of the inputs. Use the Input Active Level (INLVL) command to define the active state of all programmable inputs. Alternate between applying supply voltage Vi to an input and grounding it, using the TIN command to verify that the input toggles as you do so.

If the inputs or outputs do not appear to be functioning properly at the 6000 Controller level, refer to the Common Problems & Solutions section of the Troubleshooting chapter in the User Guide or Installation Guide for the 6000 Series Controller/Indexer being used in the application. Specific I/O problems are addressed in the table.

Note:	For additional information on 6000 Series commands,
	refer to the 6000 Series Software Reference.
