Troubleshooting/Service

Table 7-8explains how to troubleshoot Time Proportional Output failure.

Table 7-8 Troubleshooting Time Proportional Output Failure

Step	What to do	How to do it
1	Make sure the controller is configured	Make Output Algorithm Set Up group function
	for Time Proportional output.	prompt OUTALG = RLY or RLYD.
		Refer to Section 3 - Configuration.
2	Check the field wiring.	Make sure the NO or NC contact wiring is correct.
		Refer to Section 2 - Installation for details.
3	Check the output.	Put the controller into Manual mode. Vary the
		output above and below the present value.
		Observe OUT1 indicator on the operator interface.
		Contact should change state. 0 % open, 100 %
		closed. Listen for a click from the relay when the
		OUT1 indicator changes state.
4	Check relay.	Change relay.
5	Change MCU board.	Installation instructions supplied with the new
		board.
