Introduction:
The HPS2DB is a highly sophisticated and reliable starter designed for use with standard three-phase, three-wire, squirrel cage induction motors. It provides the best method of reducing current and torque during motor starting. The optional RS 485 Communication with MODBUS protocol enables full control (Start, Stop, Dual Adjust, command, etc.) and supervision. Up to 32 starters can be connected on a shield twisted pair to a host computer.
Starting & Stopping :
●Prior to Installation
Check that Motor's Full Load Ampere is lower than or equal to the starters Full Load Current and that Main
and Control voltages are as indicated on the front panel.
Mounting
● The starter must be mounted vertically, allow sufficient space
above and below the starter for suitable airflow.
● It is recommended to mount the starter directly on the rear
metal plate for better heat dissipation.
● Do not mount the starter near heat sources.
● Protect the starter from dust and corrosive atmospheres.
Temp. Range and Heat Dissipation
The starter is rated to operate over a temperature range of -10ºC
(14ºF) to + 50ºC (122ºF). Relative noncondensed humidity
inside the enclosure should not exceed 95%.
Starter's heat dissipation is approx. 3 x In (three times the
current in watts).
Example: For a 100A motor, heat dissipation is approx. 300
watts.Internal enclosure heating can be reduced through the use
of:
a. Additional ventilation
b. Employing a by-pass contactor.
Short Circuit Protection
Protect the starter against a short circuit by Thyristor Protection Fuses.
Control Terminals:
●Terminals 1-2：Control supply
110-120Vac or 220-240Vac, 50/60Hz
Terminal 3：Ground；
Terminal 4：Start Signal Input:
Input form a N.O contact. To start the motor,connect common terminal (Terminal 6) to Terminal 4 for
at least 500mSecs.
Terminal 5： Soft Start Signal Input:
Input form a N.C contact. To soft stop the motor,disconnect common terminal
( Terminal 6 ) to Terminal 5 for at least 500mSecs.
Terminal 6：Common Terminal,Common for terminals 4,5；
Terminals 7-8：Programmable Signal Relay，Programmable function:
● Run Relay(Normal Open):
Changes its position when starter running(Start/Soft Stop process or Motor running).
● Over Current Fault Relay(Normal Close):
Changes its position on Over Current Fault.
Terminals 9-10：By-pass relay, changes its position at the end of Acceleration；
Terminals 11-12：Programmable Fault Relay，changes its position on fault, the contact is programmable to
function as Normal Open or Normal Close relay；
