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 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. Pins indicate the
connection of the cables to the terminal block on the PCB board within the actuator. Unless specified by
the customer, these are pre-wired at the factory.
Wire color schematic for “Turck 6” cable:
If you have chosen to exclude the Turck cable from your order, connect the wires to the corresponding pins
on the terminal block as indicated in the schematic:

Power Supply and Draw
The MCx-xxxAS may be connected to voltages ranging within 12-24 VDC.
The current draw will range from minimum 100 mA to maximum 3 A while the actuator is active. When not
moving, the actuator draws approx. 50 mA.
Control Signal and Feedback
Locate the correct connection terminals as shown in the picture on p.2, then connect your communication
wires to PIN 3 and PIN 4 (grey and pink wires), as shown below.

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.

Baud Rate: Choose the rate at which information is transferred. See p.4.
3 –8
Actuator Address: See p.5.
9 –11
Deactivated
12
Direction/Calibration: Toggle while powered to re-calibrate actuator (find valve seat). Also sets
direction in which the actuator will open and close. See p.13.
Example: The RCM model actuator turns clockwise when the signal is decreased with DIP 12 in
the OFF position. Putting DIP 12 in the ON position will cause counter-clockwise turning for a
decrease in signal. For changes in DIP 12 position to take effect, the power to the actuator must
be cycled.
Set the communication parameters
Data bits: 8
Parity: None
Stop bits: 1
Baud Rate: The communication baud rate can be set by using the first two positions of the DIP switch
selector. Check the table below for settings.
To change the baud rate, turn off the actuator, change the setting of DIP switches and power it up again.

Response time: The response time is between 8ms to 35ms. This means, after sending a frame, you have to
wait at least 35ms for the answer coming back from the actuator.
In this example DIPs 1, 2, 5 and 12 are on.

Set the actuator address
With the DIP switch selector, you can set any address between 1 and 63. (1 = “On” 0 = “Off”).
To change the address, turn off the actuator, change the setting of DIP switches and power it up again.

Modbus Protocol
Actuator parameters can be set by using the MODBUS (RTU) protocol.
Standard supported function codes:
02 (0x02) Read Discrete Inputs
03 (0x03) Read Holding Registers.
04 (0x04) Read Input Registers.
06 (0x06) Write Single Register.
Hanbay function codes: (see p.13 for examples)
100 (0x64) Re-zero the actuator.
101 (0x65) Close the valve.
102 (0x66) Open the valve.
If you try to use any other function code, the actuator will answer with the exception code 0x01
indicating that the attempted function code is not supported.

Speed and Torque Settings
During normal operation, the actuator will try to reach the speed set by “MaximumSpeed”. If the torque required
to reach this speed exceeds the actuator model’s capability, the actuator will automatically slow down. Please
refer to the tables in the Speed and Torque Details section for each actuator model’s torque capability.
To accommodate different valves and other applications with different torque requirements, the actuator can be
set to apply different torque on the valve stem when in the seating mode. Torque during normal operation is
always 100% of the actuator’s capability.
To deal with sticking valves, at the beginning of the first reversing movement after the seating (“zeroing”) of the
valve, the actuator will apply double the power set by “MaximumPower” (up to 100% power.)
This “pull out” function is always enabled.

WARNING: High power settings can supply enough torque to damage your valve.
Please be cautious, especially when using the 100% power setting.
Note: The 66% and 100% power settings have the following particularities:
-Supply voltage needs to be min. 14 VDC for 66% setting
-Supply voltage needs to be min. 16 VDC for 100% setting
-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)

If the value in “TargetPosition” is the same as the value in “InputRangeLow” the actuator will re-zero, finding
the valve seat and closing the valve completely. This enables a new fully closed position to be established
based on normal wear of the valve seat.
If the value in “TargetPosition” is the same as the value in “InputRangeHigh” the valve will be opened to the
maximum number of turns, as set by the “NumberOfTurns” register.
Example:
The actuator parameters are set to (decimal representation for simplicity):
NumberOfTurns = 10
InputRangeLow = 500
InputRangeHigh = 2500
•To close the valve, the “TargetPosition” register has to be set to 500.
•To open the valve 5 turns, the TargetPosition” register has to be set to 1500.
