NOTES
1. No manual operaon of the actuator while the device is energized.
2. The actuator is equipped with an over heang protecon device. When the motor exceeds
the temperature of 257° F (125°C) , the overheat protecon device will automacally switch
o the motor.
3. It is necessary to take addional leakage protecon steps when installing the actuator and
pung it into service. See page 11 for more informaon on proper conduit installaon
precauons.
4. It is necessary to provide the proper sealing of the waterproof cable ends on the inlet side
of the actuator. This will help to prevent the actuator from becoming damage by water or
dirt coming into the actuator from outside sources.
5. Be sure to double check the input voltages and all other connecons.
6. Do not wire two or more actuators in either series or parallel. Otherwise, it can cause
movement to become out of control, or the motor temperatures to rise due to the
interference they can correct with each other.
7. A minimum of 18 gauge wire needs to be used for all wiring connecons.
8. The servo controller must be wired and adjusted according to the instrucon manual to
prevent any damage from occurring.
9. Service personnel for the installaon and adjustment of the actuator need to be qualied
for these operaons.
10.Do not operate the actuator purposely under overloaded condions.
11.Valve Soluons, Inc. will not be responsible in the improper modicaon or lack of proper
maintenance of the actuators.
12.All actuators have the proper wiring diagram axed to the inside cover. All wiring should
follow these diagrams.

ELECTRICAL WIRING
2 POSITION UNITS
The opening and closing operaon of the actuator is regulated with the travel limit switches which open the
power circuit to the motor. Two power legs and a common are needed in order to drive the actuator open and
closed. Auxiliary switches are for status of valve (open/closed). The 1005-X units are not equipped with the
manual override push ON/OFF buon. In order to operate the 1005-X units with the manual override, power
must be turned o or disconnected from the unit. All other units are equipped with the manual override
push ON/OFF buon which disconnects power to the motor so that the actuator can be manually operated
using the hand crank or hand wheel
Terminal wiring as follows:
1. Power common
2. Close operaon (Power Hot)
3. Open operaon (Power Hot)
4. Auxiliary contact common
5. Auxiliary contact open status
6. Auxiliary contact closed status
7. Chassis ground
MODULATING WITH SERVO CONTROL PACK (110/220VAC)
The modulang of the actuator is soware driven based on the input signal to the Servo Control Pack. Input
Signal is 4-20mA or 2-10VDC and Output (Feedback) is 4-20mA. The 1005/S-X units are not equipped with the
manual override push ON/OFF buon. In order to operate the 1005/S-X units with the manual override,
power must be turned o or disconnected from the unit.
1005S-X Units use the SF-ZB Servo Control Pack – All other units use the SF-LB Servo Control Pack
Terminal wiring as follows:
1. “N” is for power neutral
2. “L” is for line power
3. Input “-“ is for the negave input signal
4. Input “+” is for the posive input signal
5. Output “-“ is for the negave output signal
6. Output “+” is for the posive output signal
* Oponal auxiliary contacts will be wired on a separate
terminal strip (1- Common, 2- Open, 3-Closed)

MOUNTING ON A VALVE
INSTALLATION OF ACTUATOR TO VALVE (FIG. 3)
Note: Direct mounting the actuator removes the bracket and coupling from the mounting process, but
the remainder remains the same.
1. Rotate valve to full closed posion. Ensure that the valve rotates freely with no obstrucon.
2. Using the proper bolts aach the bracket to the valve – ghten loosely.
3. Place the coupling onto the stem of the valve
4. Using the manual override handle, rotate the actuator to the full closed posion so that the pointer
indicator points to “SHUT” (stang posion of the scale).
5. Insert the output drive sha of the actuator into the coupling.
6. Aach bracket to actuator and ghten all bolts.
7. Drive the actuator using the manual crank handle and conrm that the valve rotates without obstruc-
on. Ensure the valve is fully open as the actuator rotates to full open posion.
Figure 3
Figure 4
Mounting Tips:
NOTE: This is not for direct mounting the actuator to the valve.
• If providing own bracket, ensure that the materials provided are
manufactured professionally and meet the requirements in Fig. 4.
• The precision of the coupling holes is crucial to prevent any
backlash or damage to the actuator.
• It is necessary to ensure the posional angles of the coupling
holes to prevent exceeding the actuator’s working range.
• Only ghten bolts aer the actuator, bracket and valve have
been properly aligned.
The coaxiality between axes A andBshall not exceed 0.2mm.

• SHUT BUTTON - In “Set Mode” (Switch SA Points to 2) the shut buon can be used to rotate the actuator in the closed
direcon by pressing down and stopping when released. The shut buon is also used to establish the closed limits when pressed
at the same me as the “set buon”.
• SET BUTTON – In “Set Mode” (Switch SA Points to 2) the set buon is used in coordinaon with the open or closed buons
to set the posion limits.
• SA SWITCH – SA switch is the mode switch. 1 is for direct acng control mode, 2 is for the set mode, 3 is for reverse acng
control mode. Factory set at 1.
• SB SWITCH – SB switch is for loss of control signal. 1 – Actuator will rotate to the open posion upon loss of control signal,
2 – actuator will stay in place upon loss of signal, 3 -actuator will rotate to the closed posion upon loss of control signal. Factory
set at 2.
• SC SWITCH – The SF-LB Servo-Control Pack can allow for 2-10VDC* control or 4-20mA control. The SC switch selects the
applicable control signal. The SF-ZB Servo-Control Pack (used only in the 1005S Models) does not have this funconality.
*The factory default control signal is 2-10VDC.
WARNING: ANY MOVEMENT OF THE POTENTIOMETER GEAR WILL ALTER THE FUNCTIONALITY OF
THE ACTUATOR AND IT MUST BE RETURNED TO THE FACTORY FOR RE-CALIBRATION.
WARNING: CONNECT WIRING AS SHOWN IN FIGURE 9. IF POWER LEADS ARE CONNECTED TO
CONTROL SIGNAL INPUT TERMINALS, DAMAGE WILL OCCUR TO THE SERVO CONTROL PACK.

ADJUSTMENT OF ACTUATOR - MODULATING
• DB SWITCH – Allows for the selecon of dead band on the potenometer. Sengs are 1-10 which correspond to 0.5% to
5.0%.
• L1 LAMP – Green LED is the power indicator and illuminates when power is applied to terminals “N” and “L” of the Servo-
Control Pack.
• L2 LAMP – Red LED shows a malfuncon of the control signal input and illuminates when the control signal is lost or weak.
• L3 LAMP – Red LED shows a malfuncon of the posioning circuit and illuminates when the potenometer lead is open,
shorted or damaged.
• L4 LAMP – Red LED shows an over-torque condion illuminates if the valve is jammed or binding and the actuator’s torque
is exceeded.
5. Seng of Servo-Control Pack (SF-ZB and SF-LB)
• SERVO-CONTROL PACK POSTION LIMITS ARE FACTORY SET – UNLESS A CHANGE IN LIMIT SETTING IS DESIRED – NO
ADJUSTMENT SHOULD BE NECESSARY.
1. For the SF-ZB (1005S-X Models Only) Servo-Control Pack, there are two models – SF-ZB2 (2-10VDC) and SF-ZB4 (4-20mA).
The SF-LB Servo-Control Pack has a switch seng SC SWITCH which allows the user to select the control signal. For the following
procedure, select the proper control signal for the unit being adjusted.
2. Using a small screwdriver, rotate the Switch SA to “2” – this is the set mode. All sengs of the actuator can be adjusted in
the set mode.
3. FULL CLOSED POSITION LIMIT SETTING – Perform steps 1-2 above - Adjust the posion of the valve to the full closed
posion using the OPEN and/or SHUT buons. While pressing and holding the SET buon, press the SHUT buon and hold
both buons down for 4 seconds L2 LAMP will illuminate and then exnguish – release both buons at the same me. Closed
posion of the valve is now set.
4. FULL OPEN POSITION LIMIT SETTING – Perform steps 1-2 above - For Full Open limit seng the control signal must be
applied – 20mA or 10VDC depending on SC SWITCH seng. Adjust the posion of the valve to the full open posion using the
OPEN and/or SHUT buons. While pressing and holding the SET buon, press the SHUT buon and hold both buons down
for 4 seconds L2 LAMP will illuminate and then exnguish – release both buons at the same me. Open posion of the valve is
now set.
• CONTROL SIGNAL LOSS FAILURE MODE – If the control signal is lost, the actuator can be set to rotate the valve to a
predetermined state – FAIL OPEN, FAIL IN PLACE, FAIL CLOSED. Set SWITCH SB to 1 for open, 2 for in place and 3 for closed.
Factory set to 2. Note: Varying the selecon on SWITCH SB will be eecve even when the actuator is in full automac mode.
• DIRECT ACTING vs. REVERSE ACTING OPERATION – SWITCH SA is used for controlling the travel direcon of the actuator.
Actuators are factory set for direct acng (2-10V, 2V is closed and 10V is open and for 4-20mA, 4mA is closed and 20mA is open)
set SW A to 1 (direct acng). If reverse acng is desired (2-10V, 10V is closed and 2V is open and for 4-20mA, 20mA is closed and
4mA is open) set SW A to 3 (reverse acng).
• DEAD BAND SETTING – The dead band seng is used to adjust the actuators sensivity to the input control signal. The
lower the dead band seng, the more movement will occur in the actuator based on the resoluon of the control signal. Servo
Control packs are factory set to a midrange sensivity of around 3%. If less sensivity is desired, the DB SWITCH can be rotated
clockwise up to 5%. If more sensivity is desired, the DB SWITCH can be rotated counter-clockwise down to 0.5%.
5. TESTING – Set SW SA to 1 or 3 depending on the direct or reverse acng designaon. Apply the input signal to the Servo
Control Pack – verify the output signal corresponds to the input signal per the chart below.
TEST POINT INPUT SIGNAL
4mA or 2V 8mA or 4V 12mA or 6V 16mA or 8V 20mA or 10V
SCALE POINTER CLOSED “0” 2.5 5 7.5 OPEN “0”
VALVE POSITION 0% OPEN 25% OPEN 50% OPEN 75% OPEN 100% OPEN
OUTPUT CURRENT 4mA 8mA 12mA 16mA 20mA
Note: When SW SA is poinng towards posion 3 (reverse acng), the input signal of 2V or 4mA corresponds to the valve being 100%
open. The feedback reading will correspond to 100% open – 20mA.
