The operating principle of the Soft-starter should not simply take ground on a limitation of motor

current during the transitional phases or on a voltage ramp but on a torque control motor. The Soft-

starter should provide a torque ramp during the acceleration phase. Thus, it can control the torque

during the starting period and if necessary provide a motor torque constant throughout the

acceleration phase. For pumping applications, the deceleration will be on torque a ramp.

All Soft-starter sizes will have the same control board. That control board must be identical

for all applications.

All Soft-starters shall be equipped with means for measuring motor current to ensure protection.

The measurements of the current will be active when the Soft-starter is by-passed (embedded

by-pass for all sizes).

The Soft-starter should have a separate power control.

The terminals of the board control shall be of plug type for easy maintenance.

Soft Starter should control 3-phase output with Programmable display.

The Soft-starter will handle the by-pass itself: manage the closure of the by-pass at end of

acceleration time and open that by-pass at end of stop sequence. That function must be

compatible with the types of stop: freewheel, ramp

The access to the settings can be locked by code. The monitoring parameters should

remain accessible.

Environment

The maximum relative humidity will be 95% without condensation or dripping water according

to standards IEC60947-4-2.

The storage temperature can be between -25 ° C to + 70 °

Electrical characteristics of the Soft-starter

The Soft-starter will automatically adapt itself to the frequency of the mains 50 or 60 Hz with

a tolerance of + / -10%.

Outputs: the Soft-starter must have at least 2 relays with a NO/NC contact Maximum switching

capacity on inductive load: 2 A at 250 Vac and 30 Vdc.

Protections

· The starter will include the management of Motor PTC probe. · The starter will calculate continuously the motor overheating from the real current value (the

current must be measured and not estimated). Several classes of thermal protection will be

TEST DUTIES AND EFFICIENCIES:

The contractor shall state in the tables attached with tender documents the efficiencies and duties of

the pumping plants when working at specified conditions of the pumping and the guaranteed

performance in K.W. hour input per water horse power output under various conditions of working.

The guaranteed performances are also to be specified under following conditions i.e. variation in

head discharge and power consumption in the following cases:

d) When available voltage decreases from 415 volts to 380 volts or increases from 415 volts to 440

volts.

e) When there is fluctuation of ±3% in the frequency of the AC power supply from 50 C/S. f) When there is above change in voltage and frequency of the AC power supply simultaneously.

The official tests shall be conducted in two stages. Preliminary tests may be conducted at the

manufacturer’s works. The final tests shall be conducted at site. Pumps shall be run so as to

obtain the range of heads specified in the performance tables by means of throttling or opening

valves of the pumping mains and tests results will be compared with those guaranteed by

averaging the units consumption per water horse power hour.

The guaranteed figures stated above shall be subjected to no tolerance and the average results shall

be obtained during official test of plant. If the results lack average guaranteed figures the contractor

shall forfeit followings ascertained damages relating to each set installed.

If BOT unit (KWI) per WHP, the consumption is above the average guaranteed figure under the

specified Q and H, the liquidated damages will be recovered as the capitalized cost of the Extra

Energy Consumption during the useful life span 15 years of the pumping set. The liquidated

damages shall be calculated as below:

Cost of extra power consumption

to be recovered shall be equal to =Cost of extra power per annum X capitalization factor for 15

years at an interest rate of 9%.

No damage will however, be recovered if the consumption is less than 0.05 BOT units per WHP

above the guaranteed.

If on testing the discharge of pumps is found to be within the permissible limit of ±4% then the

pumping plant will be accepted without imposing any penalty. If discharge is less by 5% to 10% then

pro rate deduction @ 1% of the cost of pump and motor for less percentage of discharge shall be

made and further if the discharge is less than 10%, plant will be rejected.

It may be noted very carefully that no privilege shall be given to any offer for evaluation

purposes considering the efficiency of the pump. Better efficiency pump however shall be

preferred. For evaluation purpose pump efficiency shall be considered as 75 % but the pump will

be tested on the efficiency quoted by the firm.

The pump efficiency offered below the efficiency quoted shall be considered for evaluation as

follows:

(i) Electric charges shall be based on 16 hours of operation per day for 15 years at the prevailing

rate of Electric Charges. (ii) All future costs of yearly power consumption will be capitalized to present value at

capitalization factor @ 9% interest.

The tenders shall have to consider the condition of pumps being run at shut off head under the

pump duty variation condition as narrated above. The tenderer should ensure selection of pumps

considering shut off head at least 25% more than the duty head. However the motor should be

selected as per tender specification and scope of work defined. The possibilities of change of

duty point of each pump in parallel operation can not be ruled out under such condition tenderer

should select the pump carefully.

Penalty for delay in supply and installation-0.25% per day of the total tendered cost subject to a

maximum of 10%.
