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.
Calibration Procedure - CD Series Proportional Control
1. Set the control signal selection jumpers, refer to the Proportional PCB detail page.
2. Note that ONLY CONTROL SIGNALS are to be applied to terminals #3 through #6. To do otherwise will damage
the proportional control processor.
3. Place the LCS Mode switch in the OFF position, and apply power.
A. Note that the MODE switch is NOT a power disconnect.
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.
4. Generate a mid-travel command (12mA) then place the LCS Mode switch in the REMOTE position.
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 power from
the actuator to STOP movement.
a. Place a meter in series with terminal 3 (SIG + IN), it MUST read +12mA.
i. If it does NOT, check the polarity of the incoming analog signal to make sure it is (+)12mA.
Repeat step 4.
II. If the actuator moves momentarily and then STOPS at the mid stroke position, proceed to step 5.
a. If the actuator does not move at all, rotate the handwheel slightly in either direction to offset the
controller. The actuator should move back to the midpoint position and then STOP. Proceed to step 5.
B. The REMOTE LED will be illuminated.
5. Generate a CW move command (4mA) and verify the DIRECTION of rotation of the position indicator is CW.
A. The actuator will run CW. If it does NOT, IMMEDIATELY reposition the Move switch to the NULL position
to STOP movement and interrogate the remotely generated analog control signal AT the actuator.
B. Verify that the eld controller is generating a correct signal. Place a meter in series with terminal 3 (meter blk)
and the wire coming from the eld controller (meter red), it MUST read +4mA.
I. If it does NOT, check the polarity of the incoming analog signal to make sure it is (+)4mA.
II. Check the output command of the eld controller. Repeat step 5.
WARNING – Follow these directions carefully and in order. Actuator damage due to improper testing and
commissioning will NOT be covered under warranty.
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.
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.
