NOTES!
1) If the hydraulic piping is not fitted with a manometer, the water
hammer can be noted at the pressure relief valves;
2) Please, consider that sudden line voltage drops results in motor
torque drops. Thus, ensure that the power supply line characteristics
are within the characteristics required for motor operation;
3) If errors are detected during the motor start, check all connections
of the Soft-Starter to the power line, the motor connections, the
voltage levels of the power line, the fuses, circuit-breakers and
disconnecting switches.
Is recommended program the control type in pump control using
keypad or serial communication, see the Programming Manual
for more details. In special cases, when is not available keypad or
serial communication, is also possible to program the control type
in pump control following these instructions:
1) To enter in programming mode, keep the reset key at the SSW-07
front cover pressed during 5 seconds, keeping it also pressed
throughout the programming;
2) When in the programming mode, LEDs will turn on indicating the
actual parameterization. See item 4.10 and 4.12;
3) To modify the control type, change the Stall DIP Switch and put
it back in the previous position. The Stall LED will indicate the
new programmed control type:
- LED Stall off: P219=0. Control type defined through Voltage
Ramp/Current Limit DIP Switch.
- LED Stall on: P219=2. Control type in Pump Control and
parameterization through Trimpots and DIP Switches.
