OVERVIEW
ADAPTION POWER
The actuators feature a native
2-10 Vdc Control Signal.
Installation of the KR500
Resistor Kit converts the
Control Signal input to 4-20
mAdc. When using 4-20 mA
input, terminate the 500 ohm
resistor from the KR500 resistor
kit between the White and
Black actuator wires. When
using the VMS-35, this can be
easily done between the NO1
and LN terminals for Actuator
1 and between the NO2 and LN
terminals for Actuator 2.
A single wire brings a 2-10 Vdc
Feedback Signal. The Feedback
Signal is not available using
4-20 mAdc.
The Rotation Switch can be
adjusted to set the direction
the Control Signal opens and
closes the valve (and Loss
of Signal direction in some
actuators) in the field without
actuator removal.
Adaption (Auto-Calibration
- green LED), a combined
Adaption/ Power button to
reset and relearn the valve
stroke as well as indicate the
actuator is powered. When the
Button is pressed, the actuator
will drive one full cycle to
its mechanical end stops OR
the valves mechanical seats.
Upon completion of this cycle
the actuators working range
(Control Signal, Feedback
Signal and running time) will
be adjusted to the actual
stroke of the actuator.
Status (yellow LED) to confirm
communication.

Power Failure: Terminal AC changes to 24 V square wave from battery/
inverter. A relay breaks the connection between Terminals C1 and NO1
forcing the actuator to return to the rotation switch position (See page
13 for explanation of rotation switch position).
Loss of Signal: Terminal AC uses 24VAC building power. The control
signal is broken forcing the actuator to return to the rotation switch
position (See page 13 for explanation of rotation switch position).

INSTALLATION - PROPORTIONAL CONTROL
1. Disengage the 24 VAC building power circuit before wiring. Verify that the battery inside the VMS-35 has its wires disconnected and
leave them that way for now. Disconnect them if they are connected.
2. Connect the VMS-35 to the actuator(s) as shown on wiring diagram. The VMS-35 can power one or two actuators.
Actuator A: Connect terminal N01 to white wire from actuator to drive the valve stem to the rotation switch position. Connect terminal
AC to red wire from actuator to provide power. Connect grounded reference – negative/black wire from actuator to terminal LN. Also
connect the control signal (-) to the black wire from the actuator. Connect terminal C1 to the control signal positive (+). If the control
signal is 4-20mADC a KR500 500 ohm resistor is required. Terminate the resistor between terminals N01 an LN.
Actuator B: Connect terminal N02 to white wire from actuator to drive the valve stem to the rotation switch position. Connect terminal
AC to red wire from actuator to provide power. Connect grounded reference – negative/black wire from actuator to terminal LN. Also
connect the control signal (-) to the black wire from the actuator. Connect terminal C2 to the control signal positive (+). If the control
signal is 4-20mADC a KR500 500 ohm resistor is required. Terminate the resistor between terminals N02 an LN.
3. While still disconnected, wire the VMS-35 to 24 volts AC power. Connect the hot to terminal L then neutral to terminal LN.
4. Engage the 24 VAC building power.
5. Verify that building power is live then connect the loose red wire inside the VMS-35 enclosure to the positive (+) battery terminal and
the black wire to the negative (-) battery terminal.
NOTE: Engage the 24 VAC power to the VMS-35 before connecting the battery. Connecting the battery first causes the VMS-35 to go
into the power failure mode. If there are conditions other than power failure during which the actuator should be driven to the rotation
switch position (See page 13 for explanation of rotation switch position), replace the jumper between RC & LN with a contact that opens
on demand.
TESTING
Disconnecting the jumper between RC & LN, with building power on, will drive the actuator to the rotation switch position (See page 11
for explanation of rotation switch position).
Testing theVMS-35 and the charging system and battery is recommended yearly.To test charging measure the voltage between terminals
TG & BT. TG is negative. When the power supply is charging correctly the voltage will be 13 - 14 volts DC. To test the battery disconnect
LN or L, wait for the actuator to return to the rotation switch position (See page 13 for explanation of rotation switch position) and then
measure the voltage between TG & BT. A good and adequately charged battery will be between 10 - 12 volts DC.
The VMS-35 is a standby power supply.
It is intended to drive an actuator to either open or close a valve during a power failure. The VMS-35 can power one or two actuators.
For On-O control see Addendum B on pages 21-25.

VMS-35 (UB1213) BATTERY REPLACEMENT
PROCEDURE:
NOTE Normal valve operation under 24 VAC power need not be interrupted
during battery replacement; however, the fail-safe function will not be avail-
able until the new battery is in place, connected and sufficiently charged (typi-
cally 2-4 hours).
1. Refer to the picture (left) to locate and disconnect the Red and
Black wires from the battery.
2. Remove the two battery mounting bracket screws and remove
the battery and bracket.
3. Place the bracket over the new battery and install the
assembly as shown, using the two screws removed in step 2
(above).
4. Connect the Black wire to the black (unmarked) terminal.
5. With 24 VAC power present, connect the Red wire to the
red terminal. VMS-35 circuitry will automatically charge the
battery. (If 24 VAC is not present, the valve may move to its
fail-safe position, depending upon residual charge in the new
battery.)
6. Recycle or dispose of the old battery properly. Do not
incinerate!

SEE DRAWING D3400024 on page 16
THESE INSTRUCTIONS SHOULD ONLY BE USED IF THE SOCKET HEAD
CAP SCREWS ITEM 13 HAVE BEEN LOOSENED AND THE POSITION OF
THE ACTUATOR ITEM 1 RELATIVE TO THE LINKAGE BASE ITEM 17 HAS
BEEN CHANGED. OTHERWISE USE THE REMOVAL AND INSTALLATION
INSTRUCTIONS ON PAGE 8 & 9.
THE SILVER SPACER RING THAT COMES WITH THE ACTUATOR MUST BE
ASSEMBLED ON TOP SIDE OF YOKE WITH TURNED DOWN (MACHINED) SIDE
FACING DOWN AS SHOWN ON DRAWING D340024.
1) Push valve stem down until plug is seated. Note stem location.
2) Install hex jamnut (Item 4) on valve stem. Thread jamnut so
that one inch of threads are exposed between jamnut and
top of stem.
3) Hold jamnut on valve stem and turn the stem adapter (Item
5) until it bottoms out on the valve stem. Tighten jamnut to
the bottom of the stem adapter to secure valve stem to stem
adapter.
WARNING: THE VALVE STEM SHOULD NEVER BE
TURNED WHILE THE PLUG IS IN CONTACT WITH
THE SEAT OTHERWISE THE SEATING SURFACES
WILL BE DAMAGED VOIDING THE WARRANTY.
4) Place linkage base (Item 17), spacer ring (Item 2), and yoke
locknut (Item 3) over valve stem and onto bonnet. Watch
orientation of spacer ring and yoke locknut. Linkage base
must rest on bonnet.
5) Rotate linkage base to desired orientation. For the factory
default actuator position, when the actuator (Item 1) is
installed in the linkage base, the motor electrical wire end of
the actuator faces the outlet side of a 2-way valve, common
“C” port on a 3-way mixing, and lower “L” port on a 3-way
diverting valve. Thread yoke locknut onto bonnet and tighten
securely. Use a blunt chisel and hammer for final tightening.
6) Unlock stem connector clamp on the actuator, use fingers on
the front and back sides of black lock assembly to evenly raise
the lock assembly.
WARNING:WHEN HANDLING THE ACTUATOR TAKE
CARE NOT TO DAMAGE THE STEM CONNECTOR
CLAMP AND CROSS BAR ASSEMBLY.
7) Press the manual override button then use the actuator
manual override to lower the stem connector until a slight
resistance is felt. Then raise the stem connector approximately
2-1/4 turns of the manual override (approximately 0.086 inch)
(See manual override on page 3).
WARNING: DO NOT FORCE OR TURN THE MANUAL
OVERRIDE WHEN THE MANUAL OVERRIDE
BUTTON IS NOT PRESSED. DOING SO MAY CAUSE
DAMAGE TO THE ACTUATOR GEARS.
8) Insert first socket head cap screw (Item 13) through front
linkage lock nut (Item 14). Watch orientation. Install first
spring (Item 15) over threaded end of socket head cap screw
into spring bore of front linkage lock nut. Insert threaded end
of socket head cap screw into hole in socket for front linkage
lock nut in one of the actuator rails. The socket for the front
linkage lock nut is oriented away from the motor electrical
wire end of the actuator. Press front linkage lock nut into
socket. The teeth on the front linkage lock nut must face the
teeth on the closest linkage base track when the actuator
is installed on the linkage base. Install second spring on
exposed threaded end of the socket head cap screw. Install
threaded linkage nut (Item 16) over threaded end of socket
head cap screw so second spring is captured in spring bore
of threaded linkage nut. The dovetail on the threaded linkage
nut must face the groove in the closest linkage base track
when the actuator is installed on the linkage base. Thread the
socket head cap screw into the threaded linkage nut. Adjust
the socket head cap screw so the teeth of the front linkage
lock nut will not interfere with the teeth of linkage base track
when the actuator is installed in the linkage base in the next
step. Repeat this step with second socket head cap screw
9) Verify the valve stem is down and the plug is seated. Refer to
location noted in Step 1. Position the actuator (Item 1) in the
desired orientation. For the factory default actuator position,
the motor electrical wire end of the actuator faces the outlet
side of a 2-way valve, common “C” port on a 3-way mixing
valve, and lower“L” port on a 3-way diverting valve. Verify that
the teeth of both front linkage lock nuts will face the teeth in
the closest linkage base track when the actuator is installed
in the linkage base. Verify that the dovetail of both threaded
linkage nuts will face the groove in the closest linkage base
track when the actuator is installed in the linkage base. Press
together the linkage base tracks and insert the actuator rails
into the tracks. Slide the actuator rails into the actuator base
tracks until the metal actuator stem touches the top of the
stem adapter.
