Wiring
Wiring for Explosion Proof Actuators
The RCx-AC-BxxAx Explosion-Proof actuator does not come with a pre-installed cable, nor
cable gland. A cable gland that meets site specifications for the appropriate hazardous location
rating is required for installation. The cable gland and the cable for hazardous location should
be installed by qualified personnel in accordance with site and local requirements.
The actuator comes standard with a ½” FNPT thread cable entry. See p.13 for
location of ½” FNPT housing access. A cable with 6 wires is required; it is
recommended to use 3x 16 AWG for wires supplying power and ground, and 3x 20
AWG for wires used for the control and feedback signals.
Standards for cable gland and cable in hazardous locations:
* In explosion-proof models, the FNPT thread is not intended for conduit connection. Cable gland only.

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 table below 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.8 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.10.
10
11
Seating torque: Set how much torque the actuator exerts on the valve lever during the calibration
(finding valve seat) procedure. See p.8.
12
Direction/Calibration: Toggle switch on and off while powered to re-calibrate actuator (find valve
seat). Also sets direction in which the actuator will open and close. See p.10.
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.
In this example DIPs 1, 2, 5 and 12 are on.

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.
Changing the number of turns
With the DIP switch settings, you can adjust anything between 1 and 31 turns to represent the full signal
range of 4-20 mA. Check in the table below. (1 = “On”, 0 = “Off”).

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 1.5 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. 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” its location 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 sub-section 3).
2. For actuators that are connected to a UPS 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.
Note: if the sensing resistor R66 is removed (for 1-5 V input signals), we recommend placing a 10K
resistor between signal and signal GND.
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, 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 (0.700V 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.
4. Feedback calibration: [RCx-AC-xxxAF model actuators only]
The current feedback will be calibrated from the factory.
To re-calibrate the feedback:
a.- Turn off the actuator and 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.

Manual Override
The RCx-xxxAx actuator with manual override can also be certified for hazardous locations (CSA and/or
IECEX). The additional manual override gear case and handle has no effective ignition sources and can
therefore be used in all hazardous locations for which the actuator enclosure is certified for.
Operation of the manual override when the actuator is powered will be difficult as the actuator will try to
maintain the valve in the position it has been commanded to.
Power should be removed if the valve is to be moved manually. If the valve is moved with
the manual override when its power is turned off, it will lose its position, and it will need
to be re-zeroed (as described in the Signal Loss and Calibration section).
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.
