12.4. Setting of the Motor Current:

This setting defines the ratio of the SSW-05 Plus current and the driven motor current. The setting of this value is very important, since it defines the protection of the motor driven by the SSW-05 Plus. The setting of this function has direct influence over the following motor protections: overcurrent, overload, locked rotor, phase loss.

This protection trips during the transition between the end of the acceleration ramp time and the contact closure of the internal bypass relays of the SSW-05 Plus, when the current flowing through the SSW-05 Plus is higher than or equal to 2 times the current set with trimpot (Motor Current). This protection monitors constantly the motor current and compares it with the value set by the trimpot (Motor Current). See Item 15. This protection monitors only when SSW-05 Plus is operating at full voltage (100%). Is activated when the current is higher than the adjusted value for more than 1 second. The activation level is 60A for the following SSW-05 models: 3A to 30A. For the 45A to 85A models the activation level is 200A. The internal fault LED flashes 5 times intermittently . This protection trips during the transition between the end of the acceleration ramp time and the contact making of the internal bypass relays of the SSW-05 Plus, when the current flowing through the SSW05 Plus is higher or equal the rated level. The activation level is 37.5A for the following SSW-05 models: 3A to 30A. For the 45A to 85A models the activation level is 200A. The internal fault LED flashes 4 times intermittently. This protection monitors the current that flows through the SSW-05 Plus during the acceleration and deceleration ramp time, and compares it with the rated current of the SSW-05 Plus. Fig. 15.2 shows the trip time curves when thyristors are overloaded. The internal fault LED flashes 6 times intermittently. This protection trips when the line frequency is out of range (+/- 10%), when compared with the rated frequency (50 Hz or 60Hz). The internal fault LED flashes 1 time intermittently .

15. OVERLOAD PROTECTION:

15.1. Motor Electronic Overload Protection:

The motor overload electronic protection simulates the heating and cooling of the motor, also known as thermal image.This heating simulation uses as input data the True RMS current. Fig.

15.1 shows the curve of the actuation time with motor under overload condition. The temperature class of this function is, according to the IEC 947-4-2, Class 10.

Notes

1) When SSW-05 Plus electronics (A1 and A2) is without power control supply voltage, the thermal image is saved internally . When the power supply voltage is re-established again (A1 and A2), the value of the thermal image returns to the value present before the loss of the power control supply .

2) Always the reset is performed via Digital Input 2 (DI2) or by means of the reset button (SSW-05 front), the value of the thermal image returns to the value saved previously in the internal Soft-S tarter memory, i. e., the thermal image value of the last electronics disable is returned;

ENGLISH

English-13

Installation and Operation Manual - SSW-05 Plus

3) The reset of the electronic overload protection can be set to manual function (man). In this case the reset must be made via digital input 2 (DI2) or by means of the reset button. If the reset setting has been set to automatic (auto), the error condition will be reset automatically after the cooling of the equipment;

4) When the electronic overload protection is disabled via dip-switch, the thermal image is reset.

Notes

1)The thermal thyristor image is not saved in the internal Soft-S tarter memory . When the SSW-05 is enabled/reinitialized, the value of the thermal thyristor image assumes zero;

2)When the motor is running in full voltage, the cooling of the thyristor overload Thermal Image happens. This is because of the By-pass of the thyristors.

16. RESET:

The error condition can be reset through the reset button at the front of the SSW-05 Plus, or through a momentary contact closure (0.5 seconds) at DI2 (digital input for reset). Other alternative to reset the SSW-05 Plus is by switching On/Off the power control supply of the electronics (A1 and A2).

ENGLISH

Notes

The SSW-05 Plus also provides the automatic reset by enabling this function through the

dip-switch (auto):

1)The automatic reset occurs after 15 minutes in the following fault conditions:

- Overcurrent, Phase Loss, Locked Rotor , Immediate overcurrent of the SSW-05 Plus by-pass relay , Overcurrent before By-pass, Frequency out of tolerance, Contact of the internal By-pass relay is open, power control supply undervoltage and External Fault.

2)The automatic reset time may be changed at P206. For more details refer to Detailed Parameter Description.

3)For incorrect phase sequence there is no automatic reset.

4)For motor overload and thyristor overload there is a specific algorithm for the automatic reset time.

English-14

Installation and Operation Manual - SSW-05 Plus

Attention - Very Import ant

Both digital input (DI2) and reset button of the SSW-05 Plus should be used only for the reset after a fault condition. If the reset function is used when the SSW-05 Plus is operating at rated voltage, the internal by-pass relays will open their contacts under load, thus jeopardizing their life.

17. FAULTS AND POSSIBLE CAUSES:

When a fault is detected, the Soft-S tarter is disabled and the Fault Code is displayed by flashing LED´s or on the readout display in the EXX form, where XX is the actual Fault Code. T o rest art the Soft-Starter after a fault has occurred, the Sof t-Starter must be reset. In general, the reset can be made as follows:

disconnecting and reapplying the AC power (power-on reset); by pressing the key “RESET” on the SSW05-RS front panel (reset key); through the HMI-SSW05-RS by pressing the key (manual reset); automatic reset by enabling the function through the dip-switch (auto) or though P106 and P220. via digital input: DI2.

19.3.1. HMI-SSW05-RS Description:

The HMI-SSW05-RS has a LED display with 4 digits of 7 segments, 2 status LEDs and 5 keys. The figure below shows the front view of the keypad.

LED

Display

Led “Run”

Led “Ready”

Figure 19.4 - Front view of the HMI-SSW05-RS.

Functions of the LED Display:

The LED display shows the parameter number and its value. It also shows the fault codes and status.

Functions of the “ready” and “run” LEDs:

Ready:On - SSW-05 Plus has been powered, and is waiting for the enable command, or with full

voltage at output.

Flashing - SSW-05 in acceleration or deceleration ramp time.

Run: It is On only when SSW-05 is operating (motor is operating with full voltage).

Basic Functions of the Keys:

- Enable the Soft-St arter (Start);

- Disable the Soft-S tarter (Stop). Also resets the Sof t-Starter after a fault has occurred;

- T oggles the LED display between parameter number and it s value (number/value);

- Increases the parameter number or the parameter value.

- Decreases the parameter number or the parameter value.

Note

In the occurrence of errors when using an HMI-SSW05-RS, the reset of errors must be done through the key . Reset through the key present in the frontal of the Soft-St arter causes loss of communication of the HMI, resulting in E31. To re-establish the communication between the HMI and the Soft-Starter it is necessary to detach and to reconnect the serial cable, or else to power down and to power up the Soft-St arter again.

ENGLISH

19.3.2. Use of the keypad:

The keypad is used for programming and operating the SSW-05, allowing the following functions:

- indication of the Soft-St arter status and operation variables;

- fault indication and diagnostics;

- viewing and programming parameters;

- operation of the Soft-S tarter (Keys and ).

English-20

Installation and Operation Manual - SSW-05 Plus

19.3.3. Signaling/Indications on the HMI-SSW05-RS Display:

Soft-S tarter Status:

Soft-S tarter is ready to be started.

Soft-Starter is in fault condition. The code is flashing. In our example, the fault message is E03 (Phase Loss).

Soft-St arter is executing the function “Load factory setting (P204)”

Note

The display also flashes, besides the fault condition, in the following condition:

Attempt to change parameter with incorrect password (P000 – Access Parameter); Attempt to change not permitted parameter . Example: Parameters that cannot be changed with running motor.

19.3.4. Parameter Viewing and Programming:

All SSW-05 settings can be made through parameters. The parameter are shown on the display by the letter P followed by a number: Example (P264):

264 = parameter number

Each parameter is associated with a numerical value (parameter value), that corresponds to the selected option among the available ones for this parameter . The parameter values define the Soft-S tarter programming or the value of a variable (e.g.: current, voltage). For Soft-S tarter programming you should change the parameter content(s).

19.3.5. HMI-SSW05-RS Installation:

The HMI-SSW05-RS can be installed directly on the panel door 1 to 3mm (0.04in to 0.12in), as shown in the figure below:

Figure 19.5 - HMI-SSW05-RS Installation.

19.3.6. HMI-SSW05-RS Start-up:

After installation (including interconnecting cable), power up the Soft-S tarter. The HMI-SSW05-RS must display “rdy”.

To enable the keys and of the HMI-SSW05-RS, is necessary to program P264 ≠ 1.

19.3.7. Keypad Copy Function:

The HMI-SSW05-RS keypad still has an additional function: the Keypad Copy Function. This function is useful when one wants to copy the settings of one Soft-S tarter (source Soft-S tarter) to another (target Soft-S tarter) or one needs to program several Soft-S tarters with the same settings. This is done as follows: the parameters of the source Soft-Starter are copied to a non-volatile memory of the HMI-SSW05-RS Keypad, and then from this keypad to another Soft-S tarter (“target Soft-St arter”). The keypad copy function is controlled by the parameter P215. For further information on this function, refer to detailed parameter description of P215.

Auto-Reset Time

P215 Keypad Copy Function

Programs all parameters to the standard factory default, when P204=5. The parameters P000 and P295 are not changed when the factory default parameters are loaded through P204=5.

When any fault is detected, excepting E10, E24, E29, E31 and E67, the Soft-Starter SSW-05 can cause an automatic reset after the time programmed at P206 has elapsed If after an “auto-reset” the same fault is repeated three times consecutively , the AutoReset function will be disabled. A fault is considered consecutive if it happens again within 30 second after an auto-reset has been executed. This is fault is repeated four times consecutively , it will be displayed permanently and the Soft-Starter will be disabled. Auto-Reset Enable/Disable is executed through the Dip Switch (Man Auto) or by means of P106 and P220.

Note: For motor overload and thyristor overload there is a specific algorithm for the automatic reset time.

The keypad copy function is used to transfer the content of the parameters from one SSW to another .

Note: The Keypad Copy Function is only available when using HMI-SSW05-RS.

P215

Procedure is as follows:

1. Connect the keypad (HMI-SSW05-RS) to the SSW from which the parameters willl be copied (SSW A - source SSW).

2. Set P215=1 (copy) to transfer the parameter values from the SSW A to the keyp ad.

Action

It configures the operation mode of the Soft-St arter, in T rimpots and Dip Switch mode or HMI mode.

0 “(Trimpot and Dip Switch)” – the programming of the initial voltage, ramp time, motor

current setting and enabling of the protection devices is performed by means of the trimpots and dip switch. The values programmed through the serial communication is not used.

1 “HMI” - the programming is performed through the serial communication. The values

programmed through trimpots and dip switch is not used.

Note:

In HMI mode (P220=1) the trimpots and dip switch programming is ignored. The start voltage, ramp times, motor current setting and the protection enabling is programmed through the parameters P101, P102, P104, P105 and P106.

It configures the DI 1 digital input to operate according to the codes described below.

0- “Not used”, DI 1 digital input is disabled. The enabling commands are only accept via

serial communication (V03).

1- “Enable/Disable”, enabling only via digital input. The enabling commands via serial

communication are ignored.

2- “External Fault”, it acts only if the DI 1 digital input is open. It can also be used as

additional load protection. Example: thermal protection of the motor through dry contact (without voltage) of a protection relay (Thermostat). The enabling commands are only accepted via serial communication (V03). It enables the relay (14/23 – 24) to operate according to the following parameter setting:

1- Function “Full voltage” – the relay closes the contact only after the Soft-S tarter reached

100% of Un (By-pass), and opens the contact when the Soft-Starter has received a

switch-Off order. 2- Function “Error”, the relay closes the N.O. contact when the SSW-05 is with no error. 3- Function “Logic Command”, the relay opens and closes the relay contact according to

the BIT 5 status of the V03 basic variable.

Configures the SSW-05 models.

Its function is to set the software so the current indication in ampére (P003) is correct.

This parameter also sets the activation level of the By-pass relay protection.
