18) Statistics including Elapsed Run Time, Total Trips, Trips on Short Circuit, Start O/L, Run O/L,

Frequency, Overcurrent, Stator RTD, Non-Stator RTD, G/F LOSET and HISET, Acceleration Time,

Start Under Curve, Start Over Curve, I*I*T Start, Fail Shunt Trip, Phase Loss, Tach Accel, and 4

External Inputs

19) Learned Start Curve. When enabled, the starter will record a start curve with 100 data points of current

and time between Start and At-Speed. This data can be exported via the Comm. Port to be plotted on a

graph or spreadsheet for baseline measurement and maintenance analysis.

I) Options: Available control or protection options shall include the following:

1) Tach Feedback Starting. An optional input card shall be available to allow linear speed acceleration based

on closed loop feedback from a tachometer.

2) RTD Inputs. Allowing biasing and adjustment of the Dynamic Thermal Register based on real-world

temperature readings from up to 12 RTDs, with the following features:

(a) Programmable RTD Type, shall accept 100 ohm platinum, 100 ohm nickel, 120 ohm nickel and/or 10

ohm copper RTDs

(b) Congurable RTDs allowing for up to 6 RTDs to be used for the Stator. All RTDs can have names

assigned in programming for clear indication on the display.

Alarm. This feature shall be programmable as Enabled or Disabled..

J) Serial Communications shall be built-in as a standard feature without the need for separate modules.

1) Communications protocol shall be RS-232 to a windows based program for data entry, and/or Modbus RTU

protocol via RS485 signals.

2) Units shall be capable of being connected to an intelligent communication device in a network of up to 247

devices with unique addresses.

A) Power Ratings

1) Input: 2300, 3300, 4160VAC, +10% to –15%, 3 phase, 50/60Hz (selectable) ± 6Hz. Unit(s) will operate

with any incoming phase sequence.

2) Output: Reduced voltage 3 phase AC derived from phase-angle red inverse-parallel thyristors, ramped to

full voltage.

3) Current Rating(s): 200, 400, 600 Amps (choose size for application)

4) Output Capacity: Heavy Duty, rated as follows: Overload Capacity = 500% of unit rating for 60 seconds;

600% for 30 seconds; minimum 115% of nominal motor FLA continuous. Light duty rated starters are not

acceptable.

5) Control Power: 120VAC, 60Hz, derived from an integral transformer sized to be adequate to operate all

associated devices in each starter.

B) Power Structure

1) Disconnect Switch: A “Fault-Make / Load-Break” rated disconnect switch shall be provided in the

incoming power section of the starter assembly.

(a) Disconnect switch design voltage shall be 7200V.

(b) The Load-Break rating is to protect against any possible vacuum contactor failure, therefore isolation

switches relying on the vacuum contactor to interrupt the load shall not be used.

compartments will be as follows;
