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 on next page for DIP switch functionality.

Turns: The actuator usually ships from the factory with the recommended number of turns for the
valve. However, this number can be changed. Turning on a switch will add a specific number of
turns to the actuator’s movement.
See p.6 for relation between positions of the DIP switches and number of turns.
Example: Turning on DIP 6 adds four turns, turning on DIP 8 adds one turn. If both DIP 6 and 8 are
on, then the total turns of the actuator would be five.
9
Signal loss: See p.8.

11
Seating Torque: Set how much torque the actuator exerts on the valve lever during the calibration
(finding valve seat) procedure. See p.7.
12
Direction/Calibration: Toggle switch on and off while powered to re-calibrate actuator. Also sets
direction in which the actuator will open and close. See p.8.
Example: The MCM 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 counterclockwise turning for a decrease
in signal. For changes in DIP 12 position to take effect, the power to the actuator must be cycled.
When cycling the power, the power must be off for at least 2 minutes to ensure the battery has
switched off.
Controlling the Actuator
The 4-20 mA (or 1-5 V / 1-10 V) input signal represents a total span of a number of turns.
I.e.: If you set the number of turns to 2, then a signal of 12 mA will set the actuator to exactly 1 turn from the
fully closed position. 15 mA will give: (15-4)/16=0.6875 ⇒68.75% of 2 turns ⇒1.375 turns from closed.
In this example DIPs 1, 2, 5 and 12 are on.

WARNING: Be sure that the number of turns the actuator is set for is LESS than the number of
turns for the valve. The actuator should not stop itself on a fully opened valve. It can damage the
valve, and the actuator will lose its position.
For more turns, set DIP 4 to the ON position.
This will add 16 turns to the number set by DIPs 5
through 8, as shown in the table.

Torque Settings
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.
During normal operation, the actuator will try to reach the
speed set by DIP 1 and DIP 2. It will use 100% torque to try
and reach the selected speed, regardless of the positions of
DIP 10 and DIP 11. Current draw is limited to 3 A
regardless of settings.
Please see the box to the right and the tables below to select the power setting that is right for your
application.
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 DIP 10 and DIP 11 (up to 100% power.)
This “pull out” function is always enabled.
Speed and Torque Details
The maximum speed of the actuator can be set by using the first two positions of the DIP switch selector.
As a result of this setting, the actuator will limit the maximum speed. The tables below show the time required
to complete one turn.
The seating torque depends on the voltage provided in the power connection and on the
seating power settings on DIP 10, 11 as shown below.

Signal Loss and Calibration
1. In the event of a power loss, the battery fail-safe model will move to its designated fail-position. This
position is programmed at the factory (based on user request) and cannot be changed in the field.
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 sub-section 3).
2. The behavior on signal loss can be set as follows:
Normal position of DIP 9: OFF
With DIP 9 in the off position, the actuator will ignore the signal if it is lost (i.e.: if the signal falls below
0.700 V or 2.80 mA) and simply remain in its current position.
Predetermined signal loss position DIP 9: ON
With DIP 9 in the on position, the actuator will move to a predetermined position when the signal is
lost (i.e.: if the signal falls below 2.80 mA or 0.700 V).
Setting of the predetermined signal loss position:
a.- turn DIP 9 to the “off” position
b.- re-zero the actuator by sending and holding an input signal between
2.80 and 4.16 mA (0.700 and 1.04 V) wait until the device is re-zeroed, (i.e.: valve is closed)
c.- by varying the input signal, move the actuator to the position that is going to be the
predetermined signal loss position.
d.- switch DIP 9 to the “on” position. The current actuator position will be saved as the default
signal loss position. (The default signal position is an absolute actuator position. i.e.: not a
signal value.)
3. Re-zeroing the actuator and initiating calibration routine:
The actuator will re-zero when the input signal is between 2.80 and 4.16 mA (0.700 and 1.04 V). It
will turn clockwise until the actuator has reached the fully closed position of the valve.
If the valve is removed for any reason, the calibration routine must be initiated on the
actuator manually. This is done by toggling DIP 12 (switch position, then back to the original
position) while the actuator is powered. This will prevent damage to the valve.
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.
Remember to wait 2 minutes before restoring the power, to allow the battery board to shut down
after moving to the fail-safe position.
4. Feedback calibration: [RCx-B-xxxAF model actuators only]
The current feedback will be calibrated from the factory.
To re-calibrate the feedback:
a.- Turn off the actuator and wait 2 minutes to allow the battery board to shut down after
moving to the fail-safe position. Then disconnect the feedback and input signals. If possible,
remove the actuator from the valve.
b.- Connect the feedback signal to the signal input. Also connect the power and signal grounds.
c.- Power up the actuator with this “signal loop-back” setup.
d.- Short SP1. It will automatically run a special routine to calibrate the feedback signal to the
signal input. The whole process takes about 1.5 seconds.
e.- turn off the power and reconnect the actuator as normal.

Troubleshooting
Upon noticing a problem, your first step should almost always be to recalibrate the actuator by toggling DIP
12 while the actuator is powered. This alone can solve basic problems. See sub-section 3 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.
Battery Fail Safe Function
1. In the event of a loss of power or signal, the battery will maintain power to the P1 processor and
trigger the actuator to move the valve to its designated fail-safe position, using power from the
battery. The digital potentiometer will monitor the position of the valve during this fail-safe operation.
2. Once the valve has reached its fail-safe position, and after about one minute, the P1 processor will
go into sleep mode to preserve the battery life.
3. The actuator will not respond to commands until the power supply is restored.
Note: The battery will maintain a charge for up to 2 months without power being applied.
The fail-safe actuation can be performed for 30 cycles on the charge available in the battery.
During normal operation, from totally discharged, the batteries will take 2 hours to re-charge.
If in a critical fail-safe application, the battery function should be tested monthly.
Testing Battery Functionality
- The batteries will be continuously on charge when power is available to the actuator.
- Regardless of application, the fail-safe function should be tested monthly by signaling the unit to the
position opposite the fail position, removing the power to the actuator and observing whether the
actuator reaches the desired fail position.
- The battery voltage can be measured with a multimeter set for DC volt measurement.
Measure battery
voltage between the
connector terminals.
Value should be:
7.9 ± 0.4 VDC
