The use of binary, hexagonal code, or any other code is not acceptable and currents and measurements shall be presented as either exact values or as a percentage of the maximum value. 

Adjustments shall be made by a digital four push button keypad. No binary coded dipswitches shall be used for programming or function selection. 

The HMI shall be possible to lock to prevent unauthorised changes to the programming. 

Data should always be presented with as the actual value, and the unit of the data (i.e. V, A or % etc). 

Data entered and selections made to the Soft starter using the display and keypad shall be stored in case of a power loss. 

LED Indicators using long life LEDs shall provide additional quick annunciation of; Green LED marked Run – Flashing when given a start command during ramping and steady when they reached top of ramp, when feeding the motor with 100% voltage. 

Red LED marked Fault  – Steady when the soft starter sees and trips on any faults 

## (13) Metering 

Metering functions shall be provided through the Numeric Display for indicating the following ; 

Maximum RMS Output Current showing the highest current of the phases. Indicating range to be 0.0 – 9999 amps 

Output Voltage shall be possible to read in terms of % of the rated full voltage, in the rage of 0 – 100%. But also as an exact value in the range of 0 – 999V. 

Power factor shall be possible to read as a cosØ value. 

Real time clock:  A real time cock shall be available, in order to see when different events have occurred. 

## (14)  Serial Communication 

A neutral Serial, RS485, TCP/IP Communications shall be built-in as a standard feature. The product shall be designed to, benefitting on the flexible design concept. 

The soft starter shall have at least 255 different address options, in order to find each individual soft starter in the communication system. 

## (15)  Design Specifications 

The soft starter shall be controlled completely through solid state design algorithms. The soft starter shall be controlling the current in three of the three phases, using three anti-parallel Thyristors (SCRs) in each controlled phase. The soft starters shall be designed to the following specifications: 

## (16)  Power Ratings 

Rated Supply Voltage (Ue) : 208 to 600V, -15% to +10%, 3 phase 50/60Hz ± 5% 

Output voltage : Reduced voltage two phase AC derived from phase-angle fired inverse-parallel thyristors, ramped to full voltage. 

Output Capacity : The starting capacity shall allow the use of a class 10 over load relay up to 500% of the rated current. 

Control Supply Voltage (Us): Wide voltage range, 100-250VAC -15% to +10% for 50/60Hz ± 5%, shall be standard on each softstarter. 

## (17)  Thyristors (SCR Devices) 

PIV Ratings: (a) 230-600V 1600V Minimum
