Procedure #3

Table 7-7explains how to troubleshoot Position Proportional Output failure symptoms.

Table 7-7 Troubleshooting Three Position Step Control Output Failure

Step	What to do	How to do it
1	Make certain that the controller	Make Output Algorithm Set Up group function
	is configured for Three Position	prompt OUT ALG = TPSC.
	Step control.	Refer to Section 3.8.
		Refer to Section 3.8.
2	Check the field wiring.	Refer to Section 2 - Installation for details.
3	Check the output.	Put the controller into Manual mode and
		change the output from 0 % to 100 %.
4	Check whether the motor	Remove controller and short out Output 1 or
	drives in both directions.	Output 2. The motor should go to either open
		or closed. If it does controller is ok. If not,
		repeat Step 1.
5	Check whether the motor	Refer to the motor instructions.
	drives in either direction. If the

motor does not drive in either direction, check the motor. If the motor drives in one direction but not the other, go to Step 6

6Make sure the output relays are actuating properly.

7Change the two Output Relays or the Dual Relay Board (depending upon unit)

Put the controller into Manual mode. Vary the output above and below the present value. Observe “OT” in the Lower Display and the Relay Annunciators on the operator interface.

If they are not working properly, check the field wiring, then go to Step 5.

If they are, go to Step 7.

Installation instructions supplied with the new relays or board.
