ADDENDUM TO THE MANUAL 0899.5629 E/5 - SSW-04
This addendum refers to the following changes that have been made on the SSW-04 software from Version 4.XX to Version 5.XX.
1.
Inclusion of the time interval between starts function.
This protection acts limiting the time minimum interval between starts to avoid excessive starting and stopping according to the time adjusted in parameter P36.
- P36: Time Interval Between Starts (oFF, 1 ... 999s). Factory Standard: “oFF”.
Operation by HMI
(I/O)
Operation by three wire digital input
(E.D.1 and E.D.2)
Attention:
The SSW controller will not accept a new Start command during the time, adjusted in P36, elapsed after Stop. Identically to serial interface communication.
Operation by two wire digital input
(E.D.1)
Attention.:
The SSW controller will not accept a new Start command during the time, adjusted in P36, elapsed after Stop.
NOTE!
1) Use this function only if you need to avoid excessive starting and stopping.
2) The time counter starts after a Stop command, with or without soft stop.
3) The time adjusted in P36 must be greater than the time adjusted in P04 for this function to work properly.
4) This function doesn’t work for the Jog function.
5) During the reversal of the motor direction, the new start of the motor will be only realized after the time adjusted in P36 elapses.
ADDENDUM TO THE MANUAL 0899.5629 E/5 - SSW-04
This addendum refers to the following changes that have been made on the SSW-04 software from Version 3.XX to Version 4.XX
1. Addition of the function Watch Dog of the Serial Communication.
This protection acts when the serial communication between the master and the Soft-Starter is interrupted, causing indication and action as set in parameters P63 and P64.
- P63: Watch Dog Time of the Serial Communication (oFF, 1 ... 5s). Factory Standard: “oFF”.
- P64: Action After Watch Dog Time is Elapsed (1, 2 and 3). Factory Standard: 1.
1 = Indicates only error E29.
2 = Indicates error E29 and disables the motor by ramp, if P04 is programmed different from “oFF” and motor is stopped by inertia if equal “oFF”.
3 = Indicates error E29 and cause general disabling of the Soft-Starter. Its cats as emergency. The motor is stopped by inertia.
NOTE!
Error E29 is reset when the correct serial communication returned.
NOTE!
Enable this function only if there is cyclic serial communication with a Master.
Set the watch dog time according to the time between telegrams sent by the master.
2. Change in the setting range of P15 to: off, 1 ... 200s.
3. Addition the following NOTE! in the item 6.3.19 - Pump Control.
NOTE!
Before the first start of the Pump, disable the Pump Control function. P45 must be set at “oFF”.
Set the following parameters:
P01 = 30 ( Initial Voltage)
P02 = 15 (Acceleration Ramp Time)
P03 = 80 (Voltage Fall Step during Deceleration)
P04 = 15 (Deceleration Ramp Time)
P11 = OFF (Current Limitation)
After setting the values above start and stop the Pump. Then check the correct direction of rotation, pump flow and the current of the motor.
After the above step you can enable the Pump Control (P45 = “on”).
4. Addition the following items 10.2, 10.3 e 10.4 in the accessories chapter.
10.2 - RS-485.

2.4 - ABOUT THE
SSW-04
2.4.1 - Introduction
The SSW-04 series is a totally microprocessor controlled Soft-
Starter series which controls the starting current of threephase induction motors. In this way mechanical inmpacts on the load and current peaks on the supply network are prevented.
This series includes models from 16 to 85A, being supplied from 220V, 230V, 240V, 380V, 400V, 415V, 440V, 460V, 480V,
525V or 575V. (The available types are listed in Section 8).
The models up to 45A are with natural cooling and isolated heatsink (thyristor-thyristor modules). The models from 60A and 85A have forced cooling and isolated heatsink (Thyristor-
Thyristor Modules).
The electronic control circuit uses a 16 bit microprocessor with high performance, allowing settings and displaying by means of the interface (keypad + display) of all needed parameters.
Depending on the power, this series (SSW-04) has 2 different construction forms, as shown in Figure 2.1.

In the power stage, the line voltage is controlled by means of
6 SCR’s that allow the variation of the conduction angle of the voltage supplied to the motor.
For the internal supply of the electronics, a switched source is used with several voltages, fed independently of the power supply.
The control board contains the circuits responsible for the control, monitoring and protection of the power components.
This board also contains the control and signalling circuit to be used by the user according to its application as a relay output.
All parameters or controls for the operation of the Soft-Starter can be displayed or changed through the HMI.

Please find below a procedure to improve the performance of the control of pumps.
End setting of the pump control function:
NOTE!
This setting must be used only to improve the performance of the pump control and when the pump is already installed and able to operate at full-load.
1. Set P45 (Pump control) at "On".
2. Set P14 (undercurrent) or set P15 (Undercurrent Time) at
"OFF" until the set has finished. After then, program it again.
3. Check the correct direction of rotation of the motor, as indicated ON the pump frame.
4. Set P01 (initial voltage - % U
N
) to the level so the motor starts to run without vibration.
5. Set P02 (Acceleration Time [s]) to the starting time required by the load. With the manometer in the pipeline, check the pressure increase that must be continuous until the max.
required level is reached without overshoots.
If overshoots occur, increase the acceleration time to reduce this pressure overshoots at maximum.

The Soft-Starter SSW-04 is fitted with a Thermal Protection. This protection is very efficient for the motor protection. All Soft-Starter SSW-04 models are fitted with this protection and always it is activated, error E04 is displayed and the motor is switched off.
This thermal protection has curves that simulate the motor heating and cooling. The calculation is performed through a sophisticated software that estimates the motor temperature by means of the current that is supplied to the motor.
The actuation curves of the motor Thermal Protection are according to IEC 60947-4-2 standard.
The motor heating and cooling curves are based on long experience of the company with its motors. These curves adopt a standard three-phase motor with IP55 degree of protection. These curves also consider if the motor is cooled during operation or not.
The cooling time of the thermal image depends on the motor power, i. e., for each power, a different cooling time is considered. If a different cooling time is required, this setting can be made at P27.
The estimated value for the motor temperature is saved in non-volatile memory always the control board is switched off. Thus, always the control board is switched on, the last saved value will be returned.

DETAILED PARAMETER DESCRIPTION
EXAMPLE:
Correction of the actuation time:
A motor operating at 80% In is switched off and switched on immediately.
The starting duty is 3xIn @ 25s. The selected Thermal Class is Class 20 with 39s @ 3xIn.
The correction factor for 80% In in the table 6.4 is 0.35.
The corrected actuation time is: 0.35 x 39s = 13.7s, the actuation time is reduced from 39s at cold condition to
13.7s. This means that an immediate start is not possible before the thermal image of the motor has been cooled down.
NOTE!
For programming correctly the Thermal Class that should protect the motor against overheating, you must consider the allowed hot locked rotor time. This data is available in the catalog of the motor manufacturer.
EXAMPLE:
Suggestions on how to program the Thermal Class correctly:
Motor data:
Power: 60hp
Voltage: 380V
Rated current (In): 84.5A
Service factor (S. F.): 1.00
Ip/In: 7.2
Locked rotor time: 20s at hot (Standard catalog information)
Speed: 1775rpm
Data about the motor + load Starting:
Starting by Voltage Ramp, average starting current:
3 x the rated motor current during 25s (3 x In @ 25s).
1) In the cold chart Figure 6.10, we can find the minimum required Thermal Class that allows motor start with reduced voltage:
For 3 x In @ 25s, we select the next higher class: 15
6
DETAILED PARAMETER DESCRIPTION
2) In the hot chart Figure 6.11, we can find the maximum
Thermal Class that the motor will withstand due to the hot locked rotor time:
For 7.2 x In @ 20s, we select the next lower Class: 30
Now it is known that Thermal Class 15 allows cold start and
Thermal Class 30 is the upper limit. Thus you must select a
Thermal Class between these two Thermal Classes by considering the number of starts per hour and the time interval between motor On-Off procedures.
With a smaller Class selected, the motor protection will increase but, less starts per hour are allowed and longer time intervals between motor On-Off procedures are required.
On the other hand with a higher Class selected, the motor might be operated closer to the limit, thus more starts per hour are allowed and shorter time intervals between motor
On-Off procedures can be used.
If you are not sure which Thermal Class should be adopted between these two limits, adopt the lowest Thermal Class firstly, and only during practical tests at full load operation select the Class that is more suitable to your requirements, without exceeding the upper limit.
NOTE!
If several Thermal Classes can be applied, program one that is most suitable for your application, protecting your motor according to your duty requirements.
NOTE!
If the motor is equipped with a temperature sensor (PTC or
Thermostat) which is used for thermal protection, the thermal class of the SSW-04 can be disabled by setting P21= Off.

7.1 - ERROR AND
POSSIBLE
CAUSES
7.1.1 - Programming error
(E24)
The Soft-Starter can indicate an error of incorret programming (E24), serial errors (E2X) and Hardware errors (E0X).
The error of incorrect programming (E24) does not permit that the value, changed incorrectly, be accepted.
This error occurs when any parameter is changed with the motor OFF and under the following incompatibility conditions between the parameters.
P11 current limiting with P41 kick start.
P41 kick start with P55=4 at Jog.
P43 by-pass with P44 energy saving.
P61 at Off with ED1 driven or P55 Jog driven.
To abandon this error condition, press keys P, I, O.
7.1.2 - Serial communication error
7.1.3 - Hardware errors
(E0X)
Serial communication errors (E2X) do not permit the changing of the value or that the incorrectly transmitted value be accepted.
For further info, see please Serial Communication Manual - SSW-04.
To abandon this error condition, press keys P, I, O.
Hardware errors (E0X) disable the Soft-Starter.
To abandon this error condition, switch OFF the equipment and switch it again ON, or press RESET key.
Before doing this you must eliminate the source of the error.
NOTE!
Long connection cables between the Soft-Starter and the motor (longer than 150m (492ft)) or shielded cables can show a high reactance. This may cause error “E01”.
Solution:
Connect a three-phase reactance in series with the motor supply line. In this case, contact the manufacturer.
Note: Actuation form of the errors:
All errors E01...E08 switch Off the relay RL3 and disable the thyristor firing and indicate the error on the display.

Installation
DANGER!
Filter grounding.
Using the line filter may result in relatively high ground leakage currents.
Ensure the following:
- The filter must be permanently installed and solid grounded (bonded).
- Grounding must not rely on flexible cables and should not include any form of plug or socket that would permit inadvertent disconnection.
Make sure to fulfill the requirements of the local security standards.
1. The filter must be connected between the incoming
AC supply line and the Soft-Starter input terminals.
See Fig 9.1.
2. The Soft-Starter and filter must be mounted to a common backplane with a positive electrical bond and in close proximity to one another.
3. The lenght of the wiring among filter and Soft-
Starter inputs and must be kept as short as possible.
Figure 9.1 - Filter connection
(1) The cables shielding must be solidly connected to the common backplane, using preferably a bracket.
The backplane must be electrically conductive (have no paint).
