STATUS INDICATION LEDs
When the “STAT” LED is lit, the applicable
status indication LED(s) (pictured below) will light
to reveal the condition(s) as described below.
An external alarm connection is available.
Refer to ALARM OUTPUT CONFIGURATION
(page 31).
DEMAND
This alarm is caused by the analog Demand
signal being out of the accept range. The
bottom of the range is defined as described
in LOSS OF DEMAND SIGNAL (L.O.S.)
(page 37). This alarm can also be set if
the Demand signal exceeds approximately
5.5 V dc.
POSITION
The CPS-5 Position signal to the DCM-3 is out
of the selected range limits. Refer to OUTPUT
SHAFT POSITION SENSING (page 38).
TRQ/THRUST
This LED is inactive for Group 14 actuators.
STALL
The drive is in a stall condition and stall
protection has been activated. Refer to STALL
PROTECTION (page 29).
TEMP °F.
Drive’s internal temperature is too low or too
high. Refer to TEMPERATURE SENSING
(page 28).
FB OPEN
External position Feedback signal is enabled,
but not wired to an external load or the wiring
has failed between the drive and the monitoring
device. Refer to CONFIGURING FEEDBACK
(page 39).
STOP/LIMIT
Handswitch is in “STOP” position or the drive
is at a limit. There is no alarm unless the
DCM-3 is trying to run the motor. Refer to
STOP/LIMIT INDICATION (page 29).
When more than one status LED is required
at one time, the illuminated LEDs will cycle rather
than illuminate all at once.
CONFIGURATION
INSTRUCTIONS FORMAT
The DCM‑3 configuration section of this
manual is written from the perspective of identifying
configuration concepts, then explaining how to
accomplish the configuration with the appropriate
configuration tool.
FF
Foundation Fieldbus compatible DCM-3’s
must be connected to a Foundation Fieldbus
compatible control system. All configuration
and diagnostic settings are available through
the fieldbus interface. The Foundation Fieldbus
DCM‑3 does not have a local configuration
interface or the associated status LED’s.
HART
HART Communication Foundation compatible
DCM-3’s are used in analog control systems.
Analog signal configuration is typically part
of using a HART communicator. Digital
information can also be sent and received
over the network.
BCP
This notation indicates commands to enter
using the “Beck Configuration Port,” which is
available on all models. This port can be used
for configuration or diagnostic information.
Local
Some applications are fully analog with no
digital communication available. These
applications are served by the HART
compatible DCM-3. This model has a
local configuration interface that allows
basic changes to match the control system
requirements. The interface also includes
status LED’s to assist technicians who do not
have the benefit of digital communication.
