ABB PSE Series, PSE18, PSE370, PSE105, PSE142 Manual

Mechanical installation

Hazardous voltage! Refer to installation instructions. Disconnect and lock out power before working on this device.
Attention! Installation by person with electrotechnical expertise only.

Mounting

The PSE Softstarters exist in three different physical sizes which are designed to be mounted with M6 bolts, or bolts of equivalent dimension and strength. Verify the drilling plan on top of the box.

Mechanical installation

1. Follow the drilling instructions which can be found on the top part of the shipping box.
2. Make sure to have enough space according to our table below.
3. Install the product safely in place (may need two persons).
4. Make sure to mount the product in correct orientation according to the picture below.

Check that the distance to wall and front, as well as the mounting angle fulfills the requirements.

In applications where the softstarter is installed in an enclosure, make sure that the enclosure size is not smaller than the minimum recommended. Select size from the applicable table for IEC or UL.

Ensure a free flow of air through the product.
Risk of damage to property. Ensure that no liquids, dust or conductive parts enter the softstarter.
Using a too small enclosure and/or failure to follow the instructions in other ways, may result in overheating of the PSE Softstarter and operational disturbances.

Electrical installation

1. Connect the control supply voltage on terminals 1 and 2.
2. Connect the start/stop circuit and other I/Os.
3. Connect the mains on L1/L2/L3 and the motor to T1/T2/T3.

Hazardous voltage. Will cause death or serious injury. Turn off and lock out all power supplying this device before starting work on this equipment.
To prevent an unintended direct start it's important to first power on the control supply voltage. This will energize the bypass relays before mains are powered on to ensure the relays are in open state.

Connecting Softstarters PSE18...PSE370 Inside Delta will cause damage to the equipment, and there is a risk of death or serious injury.

Basic setup

Basic settings

1. Set Ie to motor rated current (it is the most important setting)
2. Basic parameters
   1. Initial voltage (increase if the motor is stalling or have a harsh start, default is 30%)
   2. Start ramp time (adjust the voltage ramp if needed, default is 10 sec)
   3. Current limit (possible to set specifically, default is 4xIe)
   4. Set stop parameters if needed (mostly used for pumps, default is coast to stop)

1. LED status indicators
2. LCD display with backlight
3. Exit key for cancelling parameter edits and exiting one menu level.
4. Select/Reset key for changing and storing parameter values, entering one menu level, and to reset tripping events.
5. Select/Reset key for changing and storing parameter values, entering one menu level, and to reset tripping events.

By pressing both navigation keys for a minimum of four seconds, all parameter settings will be protected from unintentional change.
Repeating this for a period of two seconds will unlock the LCD display, and allow changes to the parameter settings.
