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.

• The override button can
lock in place for NON-
CAPACITOR E024, E029
and E031 actuators.
Press the button down
and into the actuator
to lock. The OVERRIDE
BUTTON will remain
down and will need to
be pressed to return
to its original position.
• The button must be
continuously pressed
completely down
throughout travel for
E025ANDE026actuators
with CAPACITORS.
WARNING: Do not force or turn the HEX OVERRIDE SOCKET when the OVERRIDE BUTTON is not
pressed. Doing so may cause damage to the actuator gears.
Engage the manual override:
To raise the actuator stem turn the Allen key counter-clockwise.

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!
