3. TECHNICAL DATA

3.1 Introduction

The Solstart Plus electronic soft starter incorporates four thyristors (Two phase control) to start a three-phase squirrel cage induction motor. By supplying a slowly increasing voltage, it provides soft start and smooth stepless acceleration, while drawing the minimum current necessary to start the motor. A Soft Stop feature can be enabled when the Ramp-Down potentiometer is adjusted. When used, upon stop signal (disconnect discrete input voltage from terminals 3 and 4), motor's voltage is slowly reduced to zero. The Solstart Plus incorporates a built in motor protection of Overload protection, phase loss protection and under voltage protection. The Solstart Plus incorporate an internal protection to protect its heatsinks from over heating.

3.2 Rating and frames sizes

3.3 Starter Selection

Select the starter according to motor's Full Load Ampere (FLA) - as indicated on its nameplate (even if the motor will not be fully loaded). The Solstart Plus is designed to operate under the following maximum conditions:

3.4 Mains and control description

3.4.1 Mains Voltage (line to line)(Terminals/bars L1, L2, L3)

Four mains voltage levels are available: 208V, 400V, 480V, 600V.

Note:

208V applies for 208V-10% up to 220V+15% 400V applies for 400V-10% up to 400V+15% 480V applies for 480V-10% up to 480V+15% 600V applies for 600V-10% up to 660V+15%

3.4.2 Control Voltage (Terminals 1, 2)

The Solstart Plus incorporates a universal power supply unit for DC and AC control voltage. 110-230V, 50/60Hz or 110-230VDC (+10%/ -15%) is required to power the electronic circuitry and the bypass. This voltage can be from a grounded or ungrounded mains system.

3.4.3 Discrete input voltage (Terminals 3, 4)

Apply discrete input voltage to terminals 3 and 4 to soft start the motor. To stop the motor disconnect the control voltage from terminals 3 and 4. If Deceleration time is set to a value other then 0 seconds the motor will soft stop. Discrete input voltage should be in the same range as control voltage: 110-230V, 50/60Hz or 110-230VDC (+10%/ -15%). This voltage can be from a grounded or ungrounded mains system.

3.4.4 End Of Acceleration (terminals 5, 6)- Solstart Plus 58A and up.

This contact exists in Solstart Plus 58A and up. Voltage free, N.O., 8A / 250VAC, 1800VA max. The contact closes after the time adjusted on the "Ramp-Up" potentiometer. The contact returns to its original position on stop signal, on fault condition, upon voltage outage and at the beginning of Soft Stop. This contact can be used for:

• Activating a valve after a compressor has reached full speed.

• Activating a valve after a pump has reached full speed.

• Loading a conveyor after the motor has reached full speed.

3.4.5 Fault Contact (terminals 7, 8)

Voltage free, N.O , 8A, 250VAC, 1800VA max. Solstart Plus 58A and up. Voltage free, N.O , 5A, 250VAC, 1250VA max. Solstart Plus up to 44A. The contact changes its position upon fault and returns to its original position after fault has been removed and starter was reset. When disconnection of control supply the contacts will be opened.

3.5 Built-in Bypass

The Solstart Plus incorporates two internal bypass relays allowing current flow through the thyristors only during starting process. At the end of the starting process, the built-in relays bypass the thyristors and carry the current to the motor. Upon stop signal, or in case of fault, both bypass relays will open and stop the motor. When Ramp-Down potentiometer is set to allow soft-Stop process, upon stop command, the bypass relays will open immediately and the current will flow through the thyristors. The voltage will then be reduced slowly and smoothly to zero.

3.6 Soft starter protections

3.6.1 Electronic Overload

The built-in inverse time electronic overload becomes operational after 15 seconds. (This is the maximum starting time of the Solstart Plus). Trip current is factory set to 115% of Motor Full Load Current (from the setting on Motor FLC potentiometer), E.g. In order to increase the O/L trip point increase FLC setting above the calculated level.

Electronic overload curve

When this protection activates Overload LED on the front panel will lit.

3.6.2 Phase Loss

The protection becomes operational when the starter is energized. it protects the motor from single phasing. It will trip the starter when one or two phases are missing for more than 1 sec. When this protection activates Fault LED on the front panel will lit.

3.6.3 Under voltage

The protection becomes operational when the starter is energized. it protects the motor from under voltage. It will trip the starter when under voltage condition occurs for more than 1 sec. When this protection activates Fault LED on the front panel will lit.

3.6.4 Heatsink over temperature protection.

The protection becomes operational when the starter is energized. it protects the soft starter from over heating. A thermal sensor mounted on the heatsink trips the starter when its heatsink temperature rises above 85ºC. When this protection activates fault LED on the front panel will flash.

3.6.5 Fault Logic and Reset Circuits

Upon operation of any protection, the starter locks in a fault mode, disabling thyristors firing and opening the Bypass. The proper fault indication LED lit/flash and the Fault contact closes. To reset the starter, after the fault has been removed, press Reset button on starter's front panel or disconnect control voltage.

WARNING!

When Fault occurs make sure that Discrete Input Voltage (terminals 3, 4) is

disconnected otherwise upon Reset the motor will start immediately!!

Notes:

(1) - Use fuses for type 2 coordination. Refer to section 4.2.1 on page 10 (2) - Solstart Plus incorporates a universal power supply unit for DC and AC control voltage: 110230V 50/60Hz or 110-230VDC. (3) – Discrete input voltage can be either 110-230V 50/60Hz or 110-230VDC. This voltage can be from a different voltage system then the control voltage or of the same system. (4) – End Of Acceleration contact (EOA) exist in models Solstart Plus 58 and up. (5) – Fault contact closes in fault conditions. (6) - When emergency stop switch is required it is recommended to trip a series contactor or the feeding circuit breaker. (Not shown)

4.2 Wiring Notes

When mains voltage is connected to the Solstart Plus, even if control voltage is disconnected, full voltage may appear on the starter load terminals. Therefore, for isolation purposes, it is necessary to connect an isolating device before the starter.

Power factor correction capacitors must not be installed on starters load side. When required, install capacitors on starter’s line side.

WARNINGS!

Never connect the Solstart Plus “Inside Delta”!

10 • Recommended Wiring Schemes

________________________________________________________________________________________________

4.2.1 Short Circuit Protection

For “class 2 coordination”, protect the starter against a short circuit by thyristor protection fuses for I²t and fuses as in dictated in the following table:

Notes:

1. The above table is for maximum starting current of 400% of FLC, maximum starting time of 5 sec and rated voltage of 400 V.

2. Rating may change with different external conditions such as ambient temperature, forced cooling etc. Refer to fuse manufacturer catalogs to confirm correct values.

4.2.2 Transient Protection

Line transient voltages can cause a malfunction of the starter and damage to the thyristors. All Solstart Plus starters incorporate Metal Oxide Varistors (MOV) to protect from normal line voltage spikes.

When higher transients are expected, additional external protection should be used (consult factory).

6. INSTALLATION

Do not interchange line and load connections

WARNING!

Do not connect the Solstart Plus “Inside Delta”

6.1 Prior to Installation

Check that Motor’s Full Load Ampere (FLA) is lower than, or equal, to the starter’s Full Load Current (FLC) and that Mains and Control voltages are as indicated on the starter’s side label.

Make sure Starter’s FLC≥ Motor FLA! Make sure Mains voltage is right! Make sure Control voltage is right!

Solstart Plus label - example

6.2 Mounting

The starter must be mounted vertically. Allow sufficient space (at least 100mm) above and below the starter for suitable airflow. It is recommended to mount the starter directly on the rear metal plate for better heat dissipation. Do not mount the starter near heat sources. Surrounding air temperature in the cabinet should not exceed 40ºC Protect the starter from dust and corrosive atmospheres.

13 • Installation

________________________________________________________________________________________________

Area (m2) =

Note: For harsh environments (sewage treatment plants, etc.), it is recommended to order the starter with printed circuit board coating. Refer to section 3.7.1 on page 8 for ordering information.

6.3 Temperature range & heat dissipation

The starter is rated to operate over a temperature range of -10ºC (14ºF) to + 40ºC (104ºF). Relative non-condensed humidity inside the enclosure should not exceed 95%.

ATTENTION!

Operating at surrounding air temp. (Inside the cabinet) higher than 40ºC may cause damage to the starter.

Starter’s heat dissipation while motor is running and the internal bypass relays are closed is typically less than

0.3 x In (in watts). During soft start and soft stop, heating is approximately two times the actual starting current (In watts).

Example: For a 100A motor, heat dissipation is less than 30 watts while running and during starting (for example at 350A), heat dissipation is approximately 700 watts.

Important note: If motor is frequently started, cabinet should be designed for the higher heat dissipation.

Internal enclosure heating can be reduced through the use of additional ventilation.

6.3.1 Calculating the enclosure size, for non-ventilated metallic enclosure

Where: Area [m2]] - Surface area that can dissipate heat (front, sides, top).

Total heat dissipation [Watt] – The total heat dissipation of the starter and other control devices in

the enclosure. If starter is frequently started, average power should be used.

Potentiometer

Range

Description

Initial Voltage 10-80% Determines the initial voltage to the motor (torque is directly proportional

to the square of the voltage). Range: 10-80% of nominal voltage. This adjustment also determines the inrush current and mechanical shock. Too high of a setting may cause high initial mechanical shock and high inrush current (even if Current Limit is set low, as the Initial Voltage setting over-rides the Current Limit setting). Too low of a setting may result in prolonged time until motor starts revolving. The motor should start revolving immediately after Start signal

Current Limit 100-400% Determines motor's highest current during starting.

Range is 100-400% of FLC (as set on motor's FLC adjustment). Too high of a setting will allow higher currents to be drawn from mains, resulting in faster acceleration. Too low of a setting may prevent the motor from completing the acceleration process and reaching full speed.

Generally, this setting should be set to the highest acceptable value in order to prevent stalling.

Caution

Starting Current and time should not exceed the allowable conditions as shown on section Error! Reference source not found. on page Error!

Ramp Up 0.5-10 sec. Determines motor's voltage ramp-up time from initial to full voltage.

It is recommended to set Ramp-Up Time to the minimum acceptable value (approx. 5 Sec).

Notes:

1. Setting Current Limit low will extend Ramp-Up Time.

2. When motor reaches full speed before voltage reaches nominal, Ramp-Up Time adjustment is overridden, causing voltage to quickly ramp up to nominal.

________________________________________________________________________________________________

Upon Start the voltage and current increase until current reaches Current Limit value. The voltage remains at this value until motor reaches nominal speed, where current starts to decrease, voltage continues to ramp-up to nominal. At this time, the motor should have smoothly accelerated to full speed.

9. TROUBLE SHOOTING

Upon fault – motor stops, Fault LED lights and Fault Relay operates.
