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-50 BCM,
this can be easily done between
the RELAY 1 NO and 24 Vdc (-)
OUT 24 VDC - →terminals for
Actuator 1, the RELAY 2 NO
and 24 Vdc (-) OUT 24 VDC - →
terminals for Actuator 2, and
between the RELAY 3 NO and 24
Vdc (-) OUT 24 VDC - →terminals
for Actuator 1 terminals for
Actuator 3.
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.
DANGER
PRESS THE MANUAL OVERRIDE
BUTTON IN FIRMLY WHILE
OPERATING THE MANUAL
OVERRIDE. FAILURE TO DO SO
WHILE THE ACTUATOR IS POWERED
OR BEING DRIVEN TO THE POWER
FAILURE DIRECTION CAN CAUSE
SERIOUS PERSONAL INJURY AND
DAMAGE THE ACTUATOR.
!
Manual Override is possible by turning off the power, pressing the Manual Override button
and rotating the supplied Allen key in the Hex Override Socket.

INSTALLATION - PROPORTIONAL CONTROL
1. Disengage the building power circuit before wiring. Verify that the battery inside the VMS-50 BCM has its wires disconnected and
leave them that way for now. Disconnect them if they are connected.
2. Connect the VMS-50 BCM to the actuator(s) as shown on wiring diagram. The VMS-50 BCM can power one, two or three actuators.
Actuator A: Connect Relay 1 Normally Open Contact RELAY 1 NO to white wire from actuator to drive the valve stem in the
direction determined by the actuator rotation switch position. Connect 24 Vdc (+) OUT 24 VDC + →to red wire from actuator to
provide power. Connect grounded reference - negative/black wire from actuator to 24 Vdc (-) OUT 24 VDC - →. Also connect the
control signal (-) to the black wire from the actuator. Connect Relay 1 Common Contact RELAY 1 COM to the control signal positive
(+). If the control signal is 4-20mADC a KR500 500 ohm resistor is required. Terminate the resistor between Relay 1 Normally Open
Contact RELAY 1 NO and 24 Vdc (-) OUT 24 VDC - →.
Actuator B: Connect Relay 2 Normally Open Contact RELAY 2 NO to white wire from actuator to drive the valve stem in the
direction determined by the actuator rotation switch position. Connect 24 Vdc (+) OUT 24 VDC + →to red wire from actuator to
provide power. Connect grounded reference - negative/black wire from actuator to 24 Vdc (-) OUT 24 VDC - →. Also connect the
control signal (-) to the black wire from the actuator. Connect Relay 2 Common Contact RELAY 2 COM to the control signal positive
(+). If the control signal is 4-20mADC a KR500 500 ohm resistor is required. Terminate the resistor between Relay 2 Normally Open
Contact RELAY 2 NO and 24 Vdc (-) OUT 24 VDC - →.
Actuator C: Connect Relay 3 Normally Open Contact RELAY 3 NO to white wire from actuator to drive the valve stem in the
direction determined by the actuator rotation switch position. Connect 24 Vdc (+) OUT 24 VDC + →to red wire from actuator to
provide power. Connect grounded reference - negative/black wire from actuator to 24 Vdc (-) OUT 24 VDC - →. Also connect the
control signal (-) to the black wire from the actuator. Connect Relay 3 Common Contact RELAY 3 COM to the control signal positive
(+). If the control signal is 4-20mADC a KR500 500 ohm resistor is required. Terminate the resistor between Relay 3 Normally Open
Contact RELAY 3 NO and 24 Vdc (-) OUT 24 VDC - →.
3. While still disconnected, wire the 24 Vdc External Power Supply LOAD to the VMS-50 BCM. Connect the POSITIVE (+) lead to the
24 Vdc (+) IN 24 VDC+ ←terminal, then connect the NEGATIVE (-) lead to the 24 Vdc (-) IN 24 VDC - ←terminal.
4. Connect the 24 Vdc External Power Supply LINE into the building power source. For the VMS-50 PS plug the three pin LINE input
plug into the 115 VAC 50/60 Hz building power source.
5. Verify that building power is live then connect the loose red wire inside the VMS-50 BCM enclosure to the positive (+) battery
terminal and the black wire to the negative (-) battery terminal.
NOTE: Engage the building power to the VMS-50 BCM before connecting the battery. Connecting the battery rst causes the VMS-
50 BCM to go into the power failure mode.
For On-O control see pages 21-25.
Under normal conditions of 24Vdc power supplied to the VMS-50 BCM, a battery requiring an initial charge should become fully
charged in 2 to 4 hours and remain charged until a building power failure occurs. The VMS-50 BCM has a red REPLACE BATTERY
LED. For the LED to illuminate the VMS-50 BCM must be powered by a 24Vdc external power supply. The LED will illuminate if the
circuit board is unable to charge or maintain the charge of the battery. The LED will also illuminate if the battery terminals are not
connected to the circuit board. If the REPLACE BATTERY LED illuminates and the battery is connected to the circuit board replace
the battery. Typical battery life is 5 years. This common gel cell battery is available from most battery supply houses.

VMS-50 BCM (SP12-1.2 (12V1.4 AH/T1)) BATTERY REPLACEMENT
PROCEDURE:
NOTE: Normal valve operation under 24 Vdc 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 Vdc power present, connect the Red wire to the red
terminal. VMS-50 BCM circuitry will automatically charge the
battery. (If 24 Vdc 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!

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 HANDLINGTHE ACTUATORTAKE
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.
