Notice: The end stop travel (cams) of this actuator have been factory set and tested to respond between 0° and
90° degrees rotation. If NO changes to end stops are required, this unit is ready to be put into service immediately
using this procedure. IF changes to the cam positions are required, refer to the product IOM before proceeding.
Conceptually this procedure rst establishes correct direction and control; these MUST be veried in order to
proceed. Regardless of the Level of the actuator, the actuator must drive CW when commanded to do so, and
STOP when the actuator reaches the full CW travel position. The same applies for the CCW operation.
WARNING – Serious Damage to the actuator will result if the motor is allowed to drive the gear train into the
mechanical stop! Remove power from this device BEFORE making any travel adjustments.
Calibration Procedure - CD Series On/Off Control
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. Note that NO external voltage is to be applied to terminals #3 through #7. To do so may damage the LCS unit.
3. Place the LCS Mode switch in the OFF position, and apply power.
A. The blue backlit LCD screen on the face of the LCS will illuminate.
B. The actuator should NOT move.
I. If it does, IMMEDIATELY remove power from the actuator to STOP movement.
II. Check control wiring (Reference the Actuator IOM). Correct if necessary, and repeat step 3.
C. Note that the MODE switch is NOT a power disconnect.
4. Be sure there are NO REMOTE movement commands active, and place the LCS Mode switch in the REMOTE
position.
A. A. The actuator should NOT move.
I. If it does, IMMEDIATELY remove power from the actuator to STOP movement.
II. Check control wiring (Reference the Actuator IOM). Correct if necessary and repeat step 4.
B. Terminal #7 is 24V control voltage OUT of the actuator and feeds the Field control panel (i.e. PLC). With the
MODE switch in REMOTE, measure the voltage between terminals #3 (Control Reference) & #7 (Control OUT).
5. Generate a remote CW move command and verify the DIRECTION of the position indicator is CW.
A. The actuator should run CW. If it does NOT, IMMEDIATELY remove power from the actuator to STOP movement.
B. Verify that a CW command is applying proper CW control by measuring 24vac between terminals #2 (COM)
and #4 (CW). Correct and return to step 5.
C. The actuator will run until it reaches its CW end of travel position. While running in the CW direction, the LCD
display will ash the percentage of full OPEN in the center of the screen and the red FC LED will be ashing.
There will also be a small DOWN arrow just to the right of the % display, indicating a move CLOSED or CW. Upon
reaching end of travel, the red FC LED will be on steady and the display will show a graphic of a CLOSED valve.
WARNING – Follow these directions carefully and in order. Actuator damage due to improper testing and
commissioning will NOT be covered under warranty.
CAUTION – This procedure has many sections with the text “IMMEDIATELY remove power from the actuator to
STOP movement”. Quick action is necessary in case of any unexpected or uncontrolled movement to keep the actuator
from possibly driving into the mechanical stops, past the limits of the valve or damper attached, and to simply keep the
actuator in a known position for a quick, efcient installation.
