3 Motor Starter Advanced Control
Protective Features
Electronic Overload Operation
When an alarm occurs, the type of alarm will be
indicated by flashing a combination of the hand/off/auto
LED’s as indicated in the table.
Cycle
Fault Trips when the starter is activated at a rate
exceeding 20 starts per minute.
Short 24V
Trips if the starter’s combined current drawn
from the 24VDC damper actuator terminals
and contactor terminals exceeds 1 amp.
Locked
Rotor
Trips when a locked rotor condition is
detected for 0.5 seconds (Smartstart mode
only).
Max Start
Time Trips if the motor takes more than 10 seconds
to start (Smartstart mode only).
Out of
Calibration
Trips if the FLA setting is determined to be
incorrect based on the motor inrush current
(safety start mode only).
Stall
Trips if a STALL condition is detected. (0.5
seconds at 300% FLA and current slope not
decreasing). Disabled during startup.
Overload
Overload trip Class 10 or 20. Trip current =
115% of FLA. Trips when the load is greater
than the Full Load Ampere setting labeled
FLA- (1-40A). The trip time will be determined
by the Class 10/20 DIP switch.
Phase
Unbalance
Trips in the event of a phase failure or phase
unbalance greater than 70% (Smartstart
mode only)

• Ambient Operating Temperature = -20°C to 60°C
• Ambient Storage Temperature = -40°C to 85°C
DANGER
• Ensure that all connections are properly
torqued and enclosure is closed prior to
applying power to the device.
• Ensure all mechanical equipment operated by the
starter is clear for safe operation in case of starter
activation.
• When in AUTO mode, starter may be activated
remotely by the control system.

Operation Modes
ON (HAND): Press the ON mode button to manually
engage motor.
OFF (RESET): Pressing the OFF mode button
manually disengages the motor. Additionally, the OFF
button serves as a manual Reset. Press and hold
OFF for 5 seconds to Reset the starter after a fault
trip.
AUTO: When utilizing AUTO mode, the starter is
controlled by a remote Start/Stop command.
LED Status Indicators
MODE LEDs: Illuminates with corresponding mode
selection (HAND/OFF/AUTO). Flashing mode LED
signals a fault trip during the last operating mode.
All three mode LEDs will flash simultaneously during
Shutdown or Fireman’s Override operation.
RUN LED: Illuminates when starter is given a Run
signal and proof of flow is detected. LED will flash
when Run signal is present without proof of flow to
motor.
FAULT LED: Illuminates upon a fault condition or
overload trip. Starter must be returned to the OFF
mode in order to Reset.
