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
5
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.

5.1.4 Programming the control type in pump control

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-08 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.

5.2 PROTECTIONS AND PROGRAMMING

5.2.1 Suggestion on How to Program the Thermal Class

For each application exists a range of thermal classes, which might be set. The overload protection
should not trip during normal starting. Therefore it is necessary to know the starting time and
current, to determine the minimum thermal class. The maximum thermal class depends on the
motor limit.
