ACCESSING:
DESCRIPTION – The information shown on this screen is
received directly from the DBS via communications, and
represents the operational status of the DBS. These items
are:
•
DBS Software Version – If the DBS and Quan-
tum™ HD are communicating properly, a value
other than zero should be displayed here. This
represents the current version of software that
is running the DBS. A value of zero may indicate
a communications error.
•
Current Phase (A, B, C) – When the DBS is run-
ning, the actual current value for each of the
three phases will be shown here.
•
Average Current – This is a calculated value that
represents the average current from all three
phases.
•
Full Load Amps – Motor Full Load Current
(Amps) has been factory set using a switch with-
in the DBS main control board. This switch is set
based on starter size.
•
Starter Wiring –This value is read from a switch
within the DBS, and will show one of two pos-
sible types of wiring, either Delta or Inline. This
is set at installation and is shown here for infor-
mational purposes only.
•
Starter Size – This value is read from a switch
QUANTUM™ HD COMPRESSOR CONTROL PANEL
OPERATION
STATUS
DBS Starter Info
DBS Starter Info
within the DBS, and will show the size of the
starter that is being used to control the motor.
This is set at installation and is shown here for
informational purposes only.
•
Starting Mode – This value is read from a switch
within the DBS, and will show whether the start-
er is set to run at Constant Current, or is set
to Step Ramp. This is set at installation and is
shown here for informational purposes only:
•
Heatsink Temperature – This will display the
value of a heatsink thermostat that is located on
the DBS control board. If this thermostat opens
(at 85° C), a fault will occur, and the motor will
shutdown. The unit will only be able to re-start
when this thermostat resets (after be allowed to
cool) at 60° C.
•
RTD Temperature – An RTD (resistive) tempera-
ture sensor is located on the DBS starter. This
value is compared against the RTD Temperature
Warning Level and RTD Temperature Trip Level
setpoints and if the value shown exceeds either
of these setpoints, either a warning or a trip will
occur.
•
Thermal Capacity – The allowable amount of
thermal energy that can be absorbed before
damage may occur to the motor. This value is
based upon an internal calculation.
