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
E025 AND E026 actuators
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.
