g. When the actuator reaches its fully CCW (90°) end-of-travel position, the OPEN LED indicator will stay
illuminated on the face of the LCS.
5. Place the move switch in the CW (0°) position, and drive to approximately mid-travel, then stop.
6. Ensure that there are no remote movement commands active, and place the LCS mode switch in the
REMOTE position.
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 on terminals 4 – N on the actuator, correct if necessary and repeat step 6.
7. Generate a remote CW move command, and verify the direction of the position indicator is CW.
a. If it is, proceed to step 9.
8. Check the field wiring:
a. Disconnect power.
i. Remove the field wiring to terminals 6, 7, and 8.
ii. Place a jumper between terminals 6 and 7. Do not apply external power to any of these terminals.
b. Reapply 3-phase power. The actuator will move CW.
c. After confirmation, remove the jumper and reconnect the field wiring between terminal 6 and 7 only.
d. Generate a remote CW move command, and verify that the direction of the position indicator is CW.
e. Reconnect the field wiring to terminal 8.
9. Generate a remote CCW move command, and verify that the direction of the position indicator is CCW.
a. If it is CCW, proceed to step 11.
10. Check the field wiring:
a. Disconnect power.
i. Remove the field wiring to terminals 6 and 8.
ii. Place a jumper between terminals 6 and 8. Do not apply external power to any of these terminals.
b. Reapply 3-phase power. The actuator will move CCW.
c. After confirmation, remove the jumper and reconnect the field wiring to terminals 6 and 8.
d. Generate a remote CCW move command, and verify that the direction of the position indicator is CCW.
11. If the actuator does not stop at the correct position(s), fails to move in the correct direction(s), or fails to stop
moving when the respective torque switch levers are 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.
12. Place the LCS in LOCAL or REMOTE mode to put the actuator into service.
6.5 LCS Commissioning for BIC + LL Proportional 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 a mid-travel position.
2. Set the control signal selection jumpers (refer to Figure ).
3. Place the LCS mode switch in the OFF position, 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. If it does not move, proceed to step 4.
iii. Check the control wiring on terminals 4 – N on the actuator, correct if necessary, and repeat step 3.
4. Place the LCS move switch in the STOP position, and place the mode switch in the LOCAL position.
a. The actuator should not move.
5. Place the LCS move switch in the CW (0°) position, and verify that the direction of the position indicator is
CW.
a. 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.
i. When depressing the torque switch lever, the FAULT LED will illuminate on the face of the LCS.
b. While traveling to the fully CW (0°) position, the CLOSE LED will be flashing.
