Interlocking

Interlocking is provided by the use of condition blocks forExpression evaluation.

TheBoolean Fan Input (BFI)block provides a first out trap for operator indication

and the ORblock provides operator indication of bypassed conditions.

Operating the Motor Control Module

Verify the operation of motor control moduleMTR-102 in the following manner:

Step 1. Run theDeltaV Operate application.

Step 2. Energize (open) XV-101.

Step 3. Fill Tank101 to 500 gallons.

Step 4. Verify that motor control moduleMTR-102 is operating properly

by manipulating the SP_D.

Step 5. De-energize (close)XV-101 and verify that the interlock occurs.

Step 6. Adjust Tank101s level to 10 gallons and verify that the interlock

occurs.
