Dwyer FC-1000 - Manual

MODEL FC-1000 ELECTRIC FAN SPEED CONTROL
Specifications - Installation and Operating Instructions
Bulletin E-39
The Model FC-1000 Electronic Fan Speed Control is designed to yield pre-
cise modulation of the speed of a motor. Popular 0-10 VDC input works with
most process controllers eliminating the need for more expensive dampers,
damper actuators, and linkages while improving the overall energy efficiency of
the system. This compact unit offers a field selectable hard start feature which
will initiate hard start of the motor when it recieves an input signal of 1.0 VDC or
greater for increased application flexibility. To simplify mounting, there are sepa-
rate conduit openings for the low and high voltage connections. This UL recog-
nized unit offers built in radio frequency interference (RFI) suppression and
voltage surge protection exceeding IEEE C62.41 standards.
This low cost unit enables variable control of ventilation fans, condenser fan
speed control and interface with VAV box controllers. When the fan speed con-
trol is combined with any Dwyer
® 2-Wire transmitter, Love Model 16A process
controller and some single faced motors up to 1 HP approved by the manufac-
turer for speed control applications, it provides a low cost alternative to many
damper actuated systems. Model FC-1000 fan speed controls are designed for
use only as operating controls. Where an operating control failure would result in
personal injury and/or loss of property, it is the responsibility of the installer to add
devices (safety, limit controls) or systems (alarm, supervisory systems) that pro-
tect against, or warn of, control failure. A Dwyer
® Series 1900 differential power
switch and Series AN14 indicating annunciator are recommended to warn
against fan motor burnout or other system failures.
Caution: The FC-1000 may be used only with single-phase motors approved
by the manufacturer for speed control applications.
