Exceptionally, and only if the application is vibration free and the tubing is minimum ¼” dia. stainless, the actuator may be suspended on the tubing itself.

Wiring: The actuator comes standard with a Turck 6 position connector and a 20’ cable with plug. Cut the cable to the length required and then connect according to the following wire color schematic: Colour White -> Black -> Pink -> Grey -> Blue -> Brown -> Function +24VDC Power Gnd. Output TT2 Output TT1 Signal Input TT2 Signal Input TT1 Otherwise, if the Turck cable is not included in your actuator, see pg.8 for more detailed wiring instructions. Connect the power: The MDx-xxxDT may be connected to voltages ranging from 12 – 24 VDC The power consumption will range from max. 3.0A to...

Connect the signal: Locate the correct connection terminals as shown on the previous page then connect your input signal on pos. 1 and 2 and the output signals on 3 and 4 as shown below. MDx Input #1 Input #2 External I/O device supplied by user < 1mA Operation DIP switches: The DIP switches allow you to change the settings on your actuator. To flip a switch, gently use a small flat-head screwdriver. See chart below for DIP switch functionality. DIP switches. In this example DIPs 1, 2, 6 and 12 are on. DIP 1 Off Off On On Fastest settling Medium-fast Medium-slow Slowest settling Use only...

Reserved for custom function. Sets direction of offset. (Offset only available in MDH and MDF series) Sets the highest amount of offset, typically 12°. NOTE: To set maximum offset DIP’s 5,6 and 7 will need to be high for a total of 21°. The max. offset can also be set differently upon customer request. Sets medium offset, typically 6°. Sets the lowest amount of offset, typically 3°. With DIP switch 8 in the ON position, the actuator will move to 4 positions. When switch 8 is off, the actuator is limited to three positions. Switch 8 also changes the function of the output signals. Run /...

Appendix Setting the type of actuator The actuator is configured at the factory to operate with the mechanical assembly based on the amount and ratio of gears of the actuator. This is not a user selectable option. Calibration The center position calibration routine can be initiated by switching DIP 9 momentarily “on” then “off”. This will cause the actuator to go through a series of movements to determine the proper center position. This function is useful if the actuators output gear gets manually rotated while the actuator is powered down and can’t properly realign to the center by...

Main Dimensions MDM-xxxDT models MDH-xxxDT models Actuator connection cable: Select a connection cable with 6 leads. The liquid tight strain relief on the base of the actuator is designed to accommodate a cable of O.D. 2.5 - 6.5mm (0.10 - 0.26in). Be sure to not use a cable with an OD that is no bigger than this! 1.- Remove the liquid tight fitting from the actuator casing and insert the cable into it. 2.- The cable has to be stripped of its jacket for 2 inches (50mm) and the wires need 1/8” (3mm) stripped ends. 5.- Put the liquid tight fitting back and tighten (lightly with tool).
