7 Calibration
7.1 Calibration Procedure for BIC On/Off Control
- Allowing the motor to drive the gear train into the mechanical stop will result in severe
damage to the actuator! Remove power from this device before making any travel adjustments.
1. After the actuator and valve (damper) assembly have been installed with power and control connected,
before applying power, use the handwheel to rotate the actuator to the mid-travel position.
2. Ensure there are no movement commands active, and apply 3-phase power.
a. The actuator should not move.
i. If it does move, immediately remove power from the actuator to stop movement.
ii. Check the control wiring to terminals 4 – N on the actuator. Correct if necessary and repeat step 2.
iii. If it does not move, proceed to step 7.
3. To establish correct actuator response to incoming control signals, remove any wires connected to terminals
6, 7, and 8, and reapply 3-phase power. The actuator should not move as there are no external control
signals to command the actuator to move. Verify that there is zero movement in this mode.
4. Place a jumper between terminals 6 and 7. Do not apply external power to any of these terminals. The
actuator will move CW. After confirmation, remove the jumper.
5. Place a jumper between terminals 6 and 8. Do not apply external power to any of these terminals. The
actuator will move CCW. After confirmation, remove the jumper.
6. Reconnect field wiring to terminals 6, 7, and 8.
7. Generate a CW move command, and verify the direction of the position indicator is moving CW.
a. If it is not, immediately remove power from the actuator to stop movement and correct field wiring errors.
b. On LTQ008 Series units, during CW travel movement, depress the lever on the upper torque switch to
interrupt the movement of the actuator, as a check of the system.
8. Generate a CCW move command, and verify that the direction of the position indicator is CCW.
a. If it is not, immediately remove power from the actuator to stop movement and correct field wiring errors.
b. On LTQ008 Series units, during CCW travel movement, depress the lever on the lower torque switch to
interrupt the movement of the actuator, as a check of the system.
9. If the actuator does not stop at the correct position(s), fails to move in the correct direction(s), or fails to stop
movement when the respective torque switch lever is depressed, immediately stop the operation of the
actuator, and refer to the Table of Contents for the section to reference for the corrective action needed.
10. If the actuator stops at the correct positions, the actuator is fully operational and ready for immediate use.
