DESCRIPTION: Use this screen to set the specifi c Drive
safeties information for a DBS motor starter. The purpose
of a DBS motor starter is to accelerate the motor in a
smooth stepless motion, therefore it reduces supply volt-
age dip during motor start, and mechanical shock on the
compressor. These safeties are important for the safe op-
eration of the compressor and motor.
DBS STARTER
The following setpoint boxes are provided.
These setpoints are updated via communications
to the DBS controller. When a setpoint has been
changed at the Quantum™ HD, it is sent to and
updates the DBS:
• Locked Rotor Current
• Stall Time
• Jam Current Level
• Jam Run Delay
• Service Factor
• Current Unbalance Alarm Level
• Current Unbalance Warning Delay
• RTD Temperature Warning Level
• RTD Temperature Trip Delay
A pop-up menu is provided:
Read Motor Amps From – Choose one of
the following selections to determine where
to read the Motor Amps from:
• DBS – Read the Motor Amps di-
rectly from the DBS panel to the
Quantum™ HD through RS-4845
communications.
• CT – Read the Motor Amps through
an optionally connected and con-
fi gured CT (Current Transformer).
This CT, if provided, will be located
on channel 16 of analog board 1.
DBS Comms - When communications from
the Quantum™ HD to the DBS starter is fun-
ciotning normally, the software version of
the DBS panel will be shown here. A value
of zero (0) indicates that there is no com-
munications.
At the bottom of this screen is a button labeled as
[Load Factory Defaults]. Selecting this button will
cause the above listed setpoint values to be re-writ-
ten with the original factory setpoints. These set-
points are sent from the DBS panel via communica-
tions into the Quantum™ HD.
