4. DCV AND EXHAUST
Execute step one, Checkout Preparation.
–
Ensure terminals AQ and AQ1 are open. LED for both DCV and Exhaust should be off.
Actuator drives fully closed.
Connect 9V battery positive to AQ and negative to AQ1. LED for both DCV and Exhaust turn on.
Actuator drives to between 81 and 85 degrees open.
Turn Exhaust potentiometer CW until Exhaust LED turns
off.
Exhaust LED turns off with potentiometer approximately 90
percent CW. Actuator remains in position.
Turn DCV setpoint potentiometer CW. DCV LED turns off with potentiometer at approximately 9V.
Actuator drives fully closed.
Turn DCV setpoint potentiometer CCW until Exhaust LED
turns on.
Exhaust contacts close 30-90 seconds after Exhaust LED
turns on.
Turn DCV setpoint potentiometer CW. Exhaust LED turns off with potentiometer indication at
approximately 9V.
Turn Exhaust potentiometer CCW until Exhaust LED turns
on.
Exhaust contacts close 30-90 seconds after Exhaust LED
turns on.
