INSTALLATION
Mounting
In most cases, the actuator must be mounted
and supported as shown in the image to the
right. The mounting bracket is not supplied by
Hanbay.
Exceptionally, the actuator may be suspended
on the tubing itself but ONLY if the application is
vibration free and the tubing is minimum ¼” dia.
stainless.
Wiring
The actuator comes standard with a pre-installed cable gland and a 10’ cable. Cut the cable to the length
required, then connect according to the following wire color schematic:

If the cable is not included with your actuator, connect the wires according to the chart below:
Power Supply and Current Draw
The MDx-AC-xxxDT may be connected to voltages ranging within 120-240 VAC.
The current draw will range from minimum 10 mA to maximum 1.5 A while the actuator is active. When not
moving, the actuator draws approx. 5 mA.

In this example DIPs 1, 2, 5 and 12 are on.
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 the table below for DIP switch functionality.
DIP switches 1 and 2 set the actuator position control parameters. High settling speed settings are suitable
for fast positioning of light valves. Longer settling times will allow heavier valves to reach their target
positions; trying to use a fast settling setting on a high torque valve will increase current consumption when
holding position, and cause heating of the motor.
DIP switches 10 and 11 set the actuator torque. These settings are adapted to the valve at the factory. Worn-
in valves may require a higher torque setting after some time. The actuator will use 100% of available torque
to try and reach maximum speed.

Note: Medium-high and high settings require voltage supply minimum values as follows:
-Supply voltage needs to be min 14 VDC for medium-high
-Supply voltage needs to be 16 VDC for high
-When operating above 20 VDC and 66% power, Duty cycle is reduced to 50% - 25%
maximum. At these levels, the electronics produce more heat which must be dissipated
(depending on environmental temperature)

DIP 3
Reserved for custom function.
DIP 4
Sets direction of offset (offset only required in RDHand RDFmodels).
DIP 5
Sets the highest amount of offset, typically 12°. NOTE: To set maximum offset DIPs 5,6, and 7
will need to be high for a total of 21°. The maximum offset can also be set differently at the
factory (upon customer request).
DIP 6
Sets medium offset, typically 6°.
DIP 7
Sets the lowest amount of offset, typically 3°.
DIP 8
With DIP 8 in the ON position, the actuator will move to 4 positions. When DIP 8 is in the OFF
position, the actuator is limited to three positions. DIP 8 also changes the function of the output
signals. See p.6 for details.
DIP 9
Run / Calibrate
Putting DIP 9 into the off position will disable the actuator positioning control, and the motor will
not move regardless of the input signals.
When DIP 9 is moved back into the on position, the actuator will perform its homing routine, and
then move to the position commanded by the input signals.
DIP 12
DIP 12 sets the direction of rotation
Functionality
The RDx can operate as a 3-position or 4-position actuator. The 4th position is enabled by turning DIP 8 ON.
Note that inputs 1 & 2 (pins 1 & 2) are HIGH by default –a LOW signal must be sent to change the
value. Sending a HIGH signal may be harmful to the internal circuit board.

Direction of rotation and using input 1
To change the direction of rotation on the actuator change the setting on DIP 12 and cycle power to the
actuator. VERY IMPORTANT: Input 1 must always be used if only one input is used to operate the
valve. When the actuator is operated using input 1 an automatic calibration is done every
time the valve is actuated. This does not happen on input 2.
Calibration
The center position calibration routine can be initiated by switching DIP 9 momentarily “off” then “on”. This
will cause the actuator to go through a series of movements to determine the proper center position. This
function is useful if the actuator’s output gear gets manually rotated while the actuator is powered down and
can’t properly realign to the center by itself.
Troubleshooting
Upon noticing a problem, your first step should almost always be to recalibrate the actuator by toggling DIP 9
while the actuator is powered. This alone can solve basic problems.
If the actuator does not move, try following these steps:
1) Re-calibrate the actuator. This will move the actuator regardless of what signal it is receiving.
2) A sticking valve may be the problem. Remove the valve from the actuator, and re-test the actuator.
3) Remove power. Re-check the wiring and the power/signal apparatus. Power actuator, and re-
calibrate. If the problem persists, please call Hanbay for technical support.
