FMI CTS Series - Manual (Page 5)

C100A Variable Speed DC Controller
GENERAL
The FMI C100A Variable Speed DC Controller is designed to
operate with FMI Variable Speed CL and CTS Drives.
The C100A features both manual speed adjustment (“ON”
position) using a front panel mounted rotary control, as well as
electronic speed control (“AUTO” position) via a 4-20mA signal
from an external source (sensor, analyzer, process controller..
etc).
The C100A incorporates transient voltage protection with
adjustable current limit and AC fuse for protection. It features
adjustable minimum and maximum speeds along with
adjustable acceleration and IR compensation.
The electronics are housed in a gasketed NEMA 4/12 enclosure
suitable for wall mounting.
IMPORTANT: The C100A Control Unit is factory calibrated for
optimum performance. Adjusting internal pots may void
MOUNTING PROCEDURE
The C100A has two (2) mounting slots located on flanges
on each side of the chassis as shown in Diagram 7 (right)
suitable for wall or vertical panel mounting. It is
recommended that all four (4) mounting slots be utilized for
maximum stability.
There are two 1/2” NPT female conduit fittings located at
the bottom of the C100A enclosure for connecting electrical
conduit. Allow adequate access to the area surrounding
these fittings for connecting electrical conduit.
