the actuator and refer to the Table of Contents for the section to reference for the corrective action
needed.
6. If the actuator stops at the correct positions, the actuator can be put into service and is fully operational.
6.2 BIC Commissioning - 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 a mid-travel position.
2. Be sure there are NO movement commands active, and apply 3 phase power.
a. The actuator should NOT move.
i. If it does move, IMMEDIATELY remove 3 phase power from the actuator to STOP movement.
ii. Proceed to step 2.
iii. If it does NOT move, proceed to step 3.
3. Check control wiring to terminals 4~N on the actuator.
a. Remove field wiring to terminals 6, 7 & 8, then place a jumper between terminals 6 & 7. Do NOT apply
external power to any of these terminals.
b. Re-apply 3 phase power. The actuator will move CW.
c. After confirmation, remove the jumper between terminals 6 & 7, and place a jumper between terminals
6 & 8.
d. The actuator will move CCW.
e. After confirmation, remove the jumper between terminals 6 & 8, and replace the field wiring to terminals
6, 7 & 8.
f. Repeat step 1.
4. Generate a remote CW move command and verify the DIRECTION of the position indicator is CW.
a. If it is NOT, there is a problem with the field logic or wiring, troubleshoot accordingly.
b. If it is, proceed to step 4.
5. Generate a remote CCW move command and verify the DIRECTION of the position indicator is CCW.
a. If it is NOT, there is a problem with the field logic or wiring, troubleshoot accordingly.
b. If it is, proceed to step 5.
6. If the actuator does NOT stop at the correct positions, fails to move in the correct directions, or on fails to
stop movement 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.
7. Place the LCS in Local or Remote Mode to put the actuator into service.
6.3 BIC Commissioning - 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 the Proportional PCB detail page.
3. Generate a mid-travel command (12mA), and apply 3 phase power.
a. The actuator should move only to match the incoming signal, if at all.
i. If the actuator moves and continues to move away from midpoint, IMMEDIATELY remove 3 phase
power from the actuator to STOP movement.
1. Place a meter in series with terminal 4 (ref) and the wire coming from the field controller (+), it MUST
read +12mA.
