Micro SD card
A micro SD card inside the enclosure is used to load updates to the control software or to back up the program.
Motor starter
The HyPrecision 15 and 30 models have a motor starter contactor. A thermal overload relay is mounted to the bottom of
the contactor.
The HyPrecision 50 model contains a wye-delta reduced-voltage starter. When the primary motor is turned on, the
primary and wye contactors reduce the initial voltage to the starter. The starter runs until the timer expires. The timer is set
at the factory to 3 seconds.
The timer relay transfers power to the delta and primary contactors, which run at full voltage and torque. When the
contactors receive a signal to turn the pump off, the delta and primary contactors open and the motor turns off.
