Document Number: F-27945-1 Specification Sheet 2 | schneider-electric.com Dimensions (mm) Function Actuator The actuator utilizes a brushless DC motor to accurately position the main spindle via a gearbox depending on the control signal received from the controller. Upon initial start up the and self stroking activation the actuator performs a full stroke cycle to lean the valve end stop positions and to calibrate the motor speed and actuator full stroke running time. End switch point adjustment is also calibrated dur- ing this process. In case of power failure the actuator is equipped with spring return function which returns the valve and actuator back to the rest position. The actuator cannot be configured or modified between spring return stem up and spring return stem down. Fig 2 T = media temperature T° T°≥120°C (248°F) T° ≥ 120°C (248°F) When media T ° exceeds 120° mount the actuator between 45° and the horizontal position. Maximum actuator ambient temperature is 50 °C (122 °F) for chilled water media. Maxi- mum actuator ambient temperature is 46° C (115° F) when media temperature is 120° C (248° F). Mounting the Actuator to the Valve To mount the actuator to a valve, first slide the Actuator Crossbeam Coupler into position on the actuator cross beam bracket. Separately, slide the Valve Stem Coupler onto the Valve Stem. Maintaining the couplers in their positions, slide the actuator onto the valve stem then slide the U-bolt into the actuator groove on the valve neck, securing with nuts provided. Driving the crossbeam coupler down into the valve coupler completes the installation and a “click” sound may be heard as the Valve Coupler locking ring engages the Actuator Crossbeam Coupler. 1. Manual override drive socket 2. Lock screw, flat screwdriver slot 1. 2. Control Signal MP500C-SR actuator can either be controlled by an in- crease/decrease signal or by a variable direct voltage. The actuator is very flexible regarding the configuration of signal input and a direct or inverse actuation but normally for an increase/decrease the actuator retracts (moves up) on an increase signal and extends (moves down) on a decrease signal. Spring Pretension To ensure tight shut off from an assembled SR actuator and control valve for closure on spring return function, it is neces- sary during installation to align the actuator spindle with the required valve stroke and stroke limits. Refer to Installation Instructions F-27913 for the correct set-up. Position Feedback MP500C-SR actuators are equipped with a 2…10 Vdc and 0…5 Vdc position feedback signal selectable by Sw 1. End Point Switch (Accessory) When fitted, the End point switch (S2 Auxiliary Switch relay) is calibrated during the initial stroke learning procedure. The switch points electronically make at 5% and 95% of the calibrated stroke position. When actuators are controlled in normal or sequence control it is possible to use the end point switches to toggle when the valve is fully open or fully closed. Mounting and Installation Note the presence of an O-ring in the cover of the actuator and ensure it is in position as the cover is removed and re- placed. The actuator may be mounted in any position other than upside down (Fig.2). Manual Operation To operate the manual override, power to the actuator must be disconnected. The manual override procedure allows the actuator to be positioned independently of control signal and can be operated with or without the cover attached. The operating direction of both the manual override and lock screw are clearly labelled on both the cover and inside the actuator, and these labels differ based on if the actuator is purchased SRU or SRD. Manual override is conducted by using a 5mm hex (Allen) key either S-shaped, L-shaped or T-shaped tool. The action of the manual override is always against the spring tension. The actuator spindle position can be locked against the spring by twisting the lock screw in the direction as shown on the actuator. The manual override lock should only be released either by nudging the manual override by 10° in the normal direction (against the spring), or re-applying power/control signal to the actuator. When the actuator is first powered on will momentarily drive against the spring to release the manual override lock before being driven by an external control signal. The manual override and lock must only be operated in one direction. This direction is clearly labelled on both cover and inside the actuator. If the hex key is left in the hex manual override drive socket, the hex key will rotate as the actuator is driven. This is not recommended and damage could occur if the key is not free to rotate.© 2016 Schneider Electric. All rights reserved.

The MP500C-SR has a highly sen- sitive control circuity which can be influenced by interference in the control signal which the actuator can try to follow. This influence may be reduced in simple installations by shorten- ing the cable lengths below 100m and /or increasing the cross sectional area of the cable above 1.5mm² (AWG 16) and the cables are spured to only one actuator.

The factory setting is all switches in the “OFF” position. Ad- just these settings prior to engaging power and any subse- quent changes to the DIP switches will not be registered until the power is interrupted, or when switch No. 9 is initiated (End position adjustment) causing a re-calibration of the actuator and valve assembly. • SW1 Feedback signal. Select between 2…10 V and 0…5 V feedback voltage output. • SW2 Control signal MOD / INC. MP500C-SR is either controlled by a variable direct voltage, for a modulating signal (MOD), or by a 3-point increase/decrease signal (INC). • SW3 Sequence or parallel control – / SEQ. With sequence (or parallel) control (SEQ), two actuators/valves can be controlled by only one control signal. Depending on Switch 4 and 5, you can choose which part of the voltage range to use, the upper one, 5…10 V (6…10 V) or the lower one, 0…5 V (2…6 V). Note: If sequence or parallel control is not used, the switch – – – / SEQ must be in the OFF position. • SW4 Input Voltage range 0…10 / 2…10. You can choose whether to use the control signal voltage range 0…10 V or 2…10 V. • SW5 (0…5, 2…6 / 5…10, 6…10). When switch 3 (SEQ) is ON choose the operational voltage range. –OFF: low: 0…5 V (2…6 V) –ON: high: 5…10 V (6…10 V) The bracketed control voltage is operational with switch 4 ON. • SW6 Running time 60 s / 300 s. On increase/decrease control, this switch selects the running time between 60 s (Off) or 300 s (On). With modulating control, the running time is always 15 s. • SW7 Direction of movement NORM / INV. The Norm / INV switch reverses the actuator direction of movement relative to signal change. • With the switch in the NORM position, the actuator spindle moves down when the signal decreases, this closes the VP220x on a 0V control signal). • With the switch in the INV, the actuator spindle moves up when the signal decreases. Thus on the VP220x valve, this setting will provide an open valve on 0V control signal). SW8 Linearization LIN/EQ. The motorized valve character- istics can be modified. The setting LIN/EQ will make the VP220x Valve from a linear flow characteristics to an equal percentage. SW9 Input signal and stroke Calibration OP / ADJ. This switch is only used to calibrate the stroke end positions. To initiate, momentarily move the switch to the ON position then back to the OFF position. At the end of the adjustment all the other dip switch settings (1 to 8) will be registered again. ON 0-5 Vdc Floating SEQ 2-100-10 0-5, 2-6 60 sec.
