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:

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.

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.

“OutputRangeHigh” and greater or equal to “OutputRangeLow”. If you try to write a value
out of the range, the actuator will answer with exception code 0x03 indicating that the new
value is not valid.
The value stored in the “OutputRangeLow” register must always be lower than the value stored in the
“OutputRangeHigh”register. If you try to write an illogical range, the actuator will answer with exception
code 0x03 indicating that the new value is not valid.
Remember: all values sent to actuator are HEX.

Signal Loss
The “SignalLostPosition”register can be used (optional) to set the position of the actuator upon signal loss.
Signal loss can only occur when controlling the actuator with 4-20 mA (or 1-5 V) input signals, i.e. when
“TargetFromRS485Flag”is set to 1. The signal is considered lost when it falls below 2.80 mA (or 0.700 V).
1. For actuators that are not connected to a UPS (Uninterruptible Power Supply), the loss of signal
will be simultaneous with power loss. Consequently, the actuator will not be able to move anywhere.
In the shutdown process, the actual position is automatically saved to the internal EEPROM. [This
saving of the position only happens for min. 18 VDC supplies] When power is restored, the actuator
will “know” where it’s at and will simply start to follow the signal as received.
IF YOU HAVE TO turn the actuator manually when its power is turned off, it will lose its
position, and it will need to be re-zeroed (as described in the Calibration section)
2. For actuators that are connected to a UPS the actuator will move to the position defined by the
value in the “SignalLostPosition” register.
The default value is 0xFFFF (DEC: 65535). The actuator will ignore the lost signal, and simply remain
in its current position.
If the value is between “InputRangeLow”and “InputRangeHigh”, the actuator will move to the value
in SignalLostPosition when the signal is lost
Reading the Input Registers
The physical meaning of the value in the “CurrentPosition”register depends on the values in the
“OutputRangeLow”and “OutputRangeHigh”registers, as well as the “NumberofTurns” register.
Example:
The actuator parameters are set to (decimal representation for simplicity):
NumberOfTurns = 10
OutputRangeLow = 500
OutputRangeHigh = 2500
•If “CurrentPosition” equals to 500, that means the valve is closed
•If “CurrentPosition” equals to 1500, that means the valve is 5 turns opened

Calibration
If the actuator is being controlled via 4-20 mA (resp. 1-5 V) input, i.e. the “TargetFromRS485Flag”register
contains value 1, the actuator will re-zero when the input signal is between 2.80 and 4.16 mA (resp. 0.700
and 1.04 V). It will turn clockwise until the actuator has reached the fully closed position of the valve.
If the actuator is being controlled via Modbus protocol, i.e. “TargetFromRS485Flag”register contains value
0, the actuator will re-zero when the value in the “TargetPosition” register is the same as the value in the
“InputRangeLow”register.
If the valve is removed for any reason, the calibration routine must be initiated on the actuator
manually after re-mounting the valve. This is done by toggling DIP 12 (switch position, then back to the
original position) while the actuator is powered. Alternatively, use command code 0x64 (refer also to the
Modbus Protocol section). The valve will close very slowly, finding the seat and preventing any damage.
If you need to re-zero in the opposite direction (i.e.: for pressure regulators, which typically go to the “top”
fully open position at 4 mA) change the setting of DIP 12 and cycle power.
WARNING: It is VERY important that you put DIP 12 back to its original setting. Failing to do so
will make the actuator turn in the opposite direction next time you power it up.

Troubleshooting
Upon noticing a problem, your first step should almost always be to recalibrate the actuator by toggling DIP
12, or using command code 0x64, while the actuator is powered. This alone can solve basic problems. See
the Calibration section above for more details.
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.
