Chapter 6 Human-Machine Interface This chapter describes how the Human-Machine Interface (keypad, LED status indicators and LCD display) works. 6.1 Overview Ready Protection Fault 6.1.1 Application The Human-Machine Interface is used for several purposes such as setting up the PSE Softstarter parameters, including protection functions and fieldbus communi- cation.
6.1.2.1 LED status indicators The LED status indicators work as in table 6.1: Table 6.1 Color Description Ready Green • Off: when control supply voltage U s is off or uncon- nected. • Flashing light when control supply voltage U s is On and operational voltage U e is Off.
6.1.2.2 LCD display and keypad The keypad is based on the same user concept as common on mobile phones. See figure 6.1. Ready Protection Fault The LCD display contains three rows. The top row has 8 parameter icons. The middle row has a lock symbol, 4 digits and units. The bottom row has 4 param- eter icons.
Ready Protection Fault 6.1.3 Locking/unlocking the keypad 1. Press the Exit key to exit to the Information Level. 2. The keypad is unlocked if the middle row is not indicating the lock icon to the right. 3. Press both Navigation keys 4 seconds to lock the keypad, and protect all parameter settings from unintentional change from the keypad.
6.1.6 Menu structure The structure of the menu is described in figure 6.8. All different parameters and levels of the menu, and how they can be reached by scrolling, are also described.

7.4 Basic settings principal The Settings level (menu) consists of predefined parameters for the selected application which should be used if an easy and quick set- up is required. At any point, press Exit to cancel a setting and return to the informa- tion level.
7.5 Functions This chapter describes all settings and functions possible in the PSE Softstarter, as well as the easiest way of finding them. Respective default values, setting ranges and parameter strings shown in the display are also stated. 7.5.1 Rated Current I e of motor This parameter allows for configuring of the current that the softstarter will be exposed to.
7.5.3 Stop Ramp Time The Stop Ramp Time parameter allows for tuning of the time for the stop ramp to reach the End Voltage from Top of Ramp (TOR). When a stop signal is given the PSE Softstarter performs a stop ramp by control- ling the output voltage to the motor so that the voltage is decreased linearly from full voltage to the end voltage level.
7.5.4 Initial/End Voltage This parameter makes it possible to set the initial voltage level where the start ramp begins. The value for end voltage where the stop ramp ends, will automati- cally be 10 percent lower than the initial voltage. During start ramp will then the voltage increase from the initial voltage level, to full voltage.
7.5.5 Current Limit It is possible to limit the starting current by using this function. The limit can not be exceeded during start and stop ramp. When the Current Limit is reached, the output voltage stays stable until the current level falls below the limit, then the ramping continues.
7.5.6 Torque Control during start ramp It is possible to use the torque control during the start by activating this parameter. Torque control results in a more linear accelerating of the speed in a majority of applications. When using the torque control the output voltage to the motor is controlled so that the motor torque will follow a predefined optimal curve from the initial voltage level to full voltage during start.
7.5.7 Torque Control during stop ramp When activating this parameter (On) makes it possible to control the motor torque during stop. Using torque control will result in a more suitable decelerating of the speed mainly requested when stopping pumps. When using torque control the output voltage to the motor is controlled so that the motor torque will follow a predefined optimal curve for best possible stop.
7.5.8 Kick Start This parameter makes it possible to tune the kick start voltage level which is ap- plied for a short time duration, before a normal start ramp is performed. Kick Start provides enough torque during start, but still ensuring a soft start. It can be set on any of the predefined voltage levels.
7.5.9 Electronic Motor Overload Protection E.O.L. This parameter makes it possible to set the required class of motor overload pro- tection. Four different classes are available. See figure 7.21. • Class 10A • Class 10 • Class 20 • Class 30 There is an option for type of reset after tripping.
7.5.10 Underload Protection When active the Underload Protection trip if the current (I e ) will fall to a lower level than the set value for 30 seconds or more. This protection could be used to avoid for example a pump running dry, detect a broken belt or similar.
7.5.11 Locked Rotor Protection This protection will when activated trip if the motor current exceeds the set level when the motor is running at full voltage. The Locked Rotor Protection parameter will be activated when the motor has been running at full voltage (Top of Ramp) for 30 seconds.
7.5.12 FieldBus Control (optional hardware required) This parameter is used for configuration of the fieldbus communication. Con- necting the PSE Softstarter to the FieldBusPlug automatically enables fieldbus communication. To enable control of the softstarter using fieldbus, this parameter must be set to On. If FieldBus Control is set to OFF, fieldbus can only be used for monitoring softstarter data.
7.5.12.1 Fieldbus Address The parameter Fieldbus Address allows setting of address for the fieldbus com- munication. The setting range for the fieldbus address is 0...255. If the address is set to 255, the address stored in internal memory of the fieldbus plug will be used. See docu- mentation for the fieldbus plug for more details on address setting.
7.5.12.3 Fieldbus Operation When Fault This parameter is accessible only if Fieldbus Control is previously set to On. In case of fieldbus malfunction, for instance due to power loss or a broken cable, this parameter allows for different (operations in case of a fault) reactions to the fault.
7.5.12.4 Type of Operation for Reset of Fieldbus Fault Select what operation shall be asserted if a fieldbus communication fault occurs. Manual or automatic options are available. HAnd is the default value for reset of Fieldbus Fault: • If HAnd is selected - The motor will stop and manual reset is required. •...
7.7 Special functions Ready Protection Fault 7.7.1 Reset all parameter settings to user default values Start from Information Level and press in sequence the keys Exit and Select for a few seconds, as described in figure 7.29. The text string “rES” will be displayed on the LCD as in figure 7.34.
7.7.2 PSE parameter Ready Protection Fault This parameter contains information about the type of PSE Softstarter which is available. The PSE parameter must be configured after replacing the PCB. This parameter must not be changed if the PCB has not been replaced. Read chap- ter 3.3 Type designation to get information about how to find out the size of the softstarter.
