130VC-2 Electronic Actuator
for 32 Series Pilot Controls
Thank you for purchasing a 32 Series Electronic Control with
130VC-2 “e-Drive” Actuator. With proper maintenance, the actua-
tor will perform indefinitely and provide very accurate and reliable
valve control. It is built with the latest technology utilizing the high-
est quality components.
32 Series Controls
The 32 Series Actuated Pilot Controls for 300 Series Valves
consist of a hydraulic pilot subassembly and 130VC-2 Actuator.
The Cla-Val Model CDHS-32, CRA-32, CRD-32, and CRL-32 pilot
controls are factory set to full adjustment range of the pilot sub-
assembly. The 130VC-2 Actuator accepts a 4 - 20 mA remote
command set-point and positions spring-loaded hydraulic pilot
subassembly as it maintains set-point of pressure or flow rate. The
pilot subassembly is automatically linear between the limit settings.
32 Series Control Operation
A.) The 130VC-2 actuator allows 32 Series Controls to be
used in valve remote control applications where a simple change
of pilot set-point is needed. The pilot spring range is factory default
scaled to a 4 - 20 mA command input signal. SCADA instrumen-
tation provides set-point control and verification communication
based on this scale.
B.) Other suitable valve remote control applications are
where 4 - 20 mA command input signal is calibrated to specific high
and low range values. SCADA instrumentation provides set-point
control and verification communication based on system dynamic
conditions and valve’s re-ranged scale. Using a laptop computer,
the 130VC-2 actuator is calibrated in the field to specific minimum
and maximum pressure or flow control settings that are in direct
proportion to 4 - 20 mA command signal. Once values are estab-
lished, the valve will be linear between limits and set-point will not
exceed limits throughout the 4 - 20 mA signal range. For example,
when actuator is calibrated to 4 mA = 50 psi to 20 mA = 100 psi, a
12 mA command signal will result in a 75 psi set point.
32 Series Actuator Hardware Set-up
BEFORE running actuator or software program, complete the
following hookup steps:
A.) Use good field wiring practices for low voltage DC analog
instrumentation wiring (use 18-gauge twisted pair shielded wire
minimum). Avoid potential ground loops. Avoid over tightening
wiring connector fasteners.
B.) The enclosure is rated IP-68 (similar to NEMA 6P) sub-
mersible for short periods of time. It is not intended for continuous
underwater use. Consult Cla-Val factory technical support if you
have questions.
C.) The five-wire cable is permanently attached to 130VC-2
actuator and should be terminated in suitable junction box for all
field wires. Care should be used when attaching to wires to avoid
damage. Installation of suitable protection from lightning is recom-
mended.
D.) There are no user serviceable parts inside the actuator
and tampering or opening it will void the warranty.
CAUTION! The five-wire actuator cable is permanently attached.
Internal damage not covered by warranty will occur if cable is
shortened or removed.
FIELD WIRING STEPS:
Download Wiring Diagram from website (www.cla-val.com)
A.) Attach 12 to 24 VDC power to 130VC-2 Actuator cable.
Black wire is common for - power; Red wire is for + power. Provide
minimum 800 mA supply.
B.) Attach 4 to 20 mA analog Remote Command Input (from
SCADA system or loop calibrator) to 130VC-2 Actuator cable.
Black wire is common for - return; Yellow wire is for + sink.
C.) Blue and Green wires are not used at this time.
CAUTION! Do NOT Mix connections to Red, Yellow, or Black
wires. Serious damage to 130VC-2 Actuator will occur if 24 VDC
+ positive power is connected to Black or Yellow wires and not to
Red wire. Damage is NOT covered by warranty.
D.) After wiring is complete and actuator is powered, it can be
used with 4 - 20 mA remote command input signal scaled to facto-
ry default pilot control adjustment range (Operation A, above).
Troubleshooting Actuator Set-up
1.) The actuator LED will remain red for approximately 30
seconds after power on, and then will switch to green indicating
actuator is OK and that internal start-up test is complete.
2.) The actuator LED blinks red if there is a problem. After
resolving the problem, reset the actuator by turning power off for
ten seconds then on again.
3.) If other problems occur, please contact Cla-Val factory
technical support.
32 Series Software Kit
For Operation A (above) applications, no changes to the 32 Series
control preset values are needed. For Operation B (above) appli-
cations, the 32 Series Software kit is used to ONLY change facto-
ry-set values of: 1) range limits (high and low), 2) rotational speed
of actuator, and 3) loss of signal mode. It is used only for set-up of
32 Series pilot controls during initial valve start-up or during valve
repair.
The Cla-Val 130VC-2 Software Kit is required to communicate
between your Windows XP laptop computer and 130VC-2
Actuator. It consists of a free software program, a special USB
connector cable, and these instructions. The software is obtained
by downloading from our website. Only one cable is needed to
work with all 130VC-2 Actuators. Replacement cables (p/n
20519203A) can be ordered at extra cost.
Do not use this software for remote control of 130VC-2 Actuator.
