按照规定,对设备或机器的任何电气或机械部件进行操作之前,ATS 48 的控制 (CL1-CL2) 和电 源 (1/L1-3/L2-5/L3) 必须断开。 在运行过程中可以通过取消运行命令使电机停机。起动器保持通电。如果为了人员安全需要禁止突 然重起动,则此电气锁定系统是不够的 : 必须在动力电路上安装一个断路器。

本起动器装有安全设备,当出现故障时,可以停止起动器工作继而使电机停机。电机自身可以通过 机械锁定停机。另外,电压变化或电源故障也会导致停机。 如果导致停机的原因消失,则存在重新起动的可能,这将危及某些机器或设备的安全,特别是那些 必须符合安全规范的机器或设备。在这种情况下用户必须采取措施预防自动重起动的发生,特别是 在电机出现不合程序要求的停机时,要使用低速检测器切断起动器的电源。

本文档中介绍的产品和设备可能会因技术原因随时变更或修改。我们保留更改的权力。

起动器安装和设置必须符合国际和国内标准的要求。系统集成商有责任确保设备的合格性,必须遵 守欧盟范围内其他国家的 EMC 规范。 本文档中的技术规范必须遵守,以符合 EMC 条款的基本要求。

ATS 48 必须被视为一个组件,它不是一部已经能够符合欧洲规范的机器或设备 ( 机械规范和电 磁兼容性规范 )。最终的集成商有责任确保其符合相关的标准。

操作建议

有效力矩
曲线 Ts 和 Is 表示异步电机直接起动。 曲线 Ts1 表示使用 ATS 48 可获得的总的力矩范围,它取决于限 制电流 ILt。起动器的逐级起动由此范围内的电机力矩控制。


Tr: 阻力矩,它必须低于 Ts1 力矩。



选择软起动 - 软停止单元
S1 电机负载对应于恒载运行,允许获得热平衡。 S4 电机负载对应于周期运行,运行周期由起动、恒载运行和停止过程组成,该周期由负载系数表示。 必须根据应用类型 ( “标准”或 “重载” ) 和电机额定功率对 ATS 48 进行选择。 “标准”或 “重载”型 应用定义了电流限定值和电机负载 S1 和 S4 周期。 注意 : ATS 48 不要使用电机之外的其他负载 ( 例如禁止使用变压器和电 阻器 )。不要将功率因数校正电容连接在由 ATS 48 控制的电机的端子上。

标准应用
例如 : 离心泵 在标准应用中, ATS 48 设计能够提供如下功能 : ? 在 S1 负荷中 : 冷态以 4In 电流持续 23 秒或 3In 电流持续 46 秒起动。 ? 在 S4 负荷中 : 负载系数 50%,每小时起动 10 次,以 3In 持续 23 秒或 4In 电流起动 12 秒,或与此相当 的热循环。 在此情况下,电机热保护必须符合 10 级保护等级。

重载应用
例如 : 研磨机 在重载应用中, ATS 48 设计用于 S4 负荷,负载系数为 50%,每小时起动 5 次,电流 4In 持续 23 秒或 与此相当的热循环。 在此情况下,电机热保护必须符合 20 级保护等级。电流 In 决不能保持在出厂设定值,而必须设定为电机 铭牌上所示的值。 注 : 起动器选型可以选大一级,例如对 11kW-400V、以电机负荷 S4 运行的电机可选用 ATS 48D17Q。 为此,应在起动过程结束时将 ATS 48 短路。允许每小时起动 10 次,3 倍 In 电流最长持续 23 秒或相当 的热循环,电机热保护必须符合 10 级要求。

操作建议
ATS 48Q 系列 (230-400V) 连接到电机三角形绕组,与每一绕组串联
ATS48???Q 起动器可以串联接入电机三角形绕组中。它们由 1/ 3 定值的起动器。 线电流的电流驱动,这样可以使用低额

此选项可以在高级设定菜单 (Advanced settings menu) 中进行配置 (dLt=On)。 额定电流和限制电流设定值以及运行过程中显示的电流均为在线值,因此不需要由用户自己计算。 对于 ATS48??? 起动器,只有 ATS 48Q 可串联连接在电机三角形绕组中。这样 : - 只能自由停车 - 不能使用级联功能 - 不能使用预热功能 关于起动器 - 电机组合的更多信息可参见第 12 页表格。

中 文

连接在电机三角形绕组中

例如 : 1 台 400V-110kW 电机,线电流 195A ( 三角形连接的额定电流 )。 每一绕组中的电流等于 195/1.7,即 114A。 选择最大允许额定电流稍大于此电流的额定值,即 140A 作为额定值 (ATS48C14Q 用于标准应用 )。 为避免计算额定值,可以使用 14 和 15 页的表,表中给出对应于每种应用类型电机功率的起动器额定值。

电机额定电流 In 不能超过 20 级的最大允许电流。 (1) 当没有对应的标准化电机时未给出值。

温度降容
上表中的值是根据最高环境温度 40°C 时的运行情况给出的。 ATS 48 最高可以在 60°C 环境温度下使用, 40°C 以上每升高 1°C, 20 级最大允许电流降低 2% 即可。 例如 : ATS 48D32Y 在 50°C 下运行, 则应降容 10 × 2%=20%, 22A 变为 22 × 0.8=17.6A ( 最大电机额定 电流 )

接线指导
电源接线
按照标准中推荐的电缆截面积选用电缆。 起动器必须接地以符合有关漏电流的规范。当安装标准要求使用进线 “残余电流设备”用于保护时,必须 使用一个 A-Si 类型设备 ( 避免上电过程中出现意外脱扣 )。检查它与其他保护设备的兼容性。如果安装中有 若干起动器连接在同一条线上的情况,则每个起动器必须单独接地。如有必要,应安装一个进线电抗器 ( 参 见产品目录 )。 动力电缆应与弱电信号 ( 检测器、 PLC、测量仪表、视频、电话 ) 电路保持隔离。

中 文

控制接线
控制线与动力电缆应保持隔离。

RUN ( 运行 ) 和 STOP ( 停机 ) 逻辑输入端的功能
2 线控制

( 见 30 页应用接线图 )

运行和停机是由状态 1 ( 运行 ) 和 0 ( 停机 ) 进行控制, RUN 和 STOP 输入状态同时考虑。 在上电或故障手动复位时如果有 RUN 命令则电机会重新起动。

3 线控制
运行和停机由 2 个不同的逻辑输入端控制。 断开 ( 状态 0) STOP 输入可获得停机。 在 RUN 输入端的脉冲一直存储到停机输入断开为止。 在上电或故障手动复位时或在一个停机命令之后,电机只能在 RUN 输入端已断开 ( 状态 0) 之后跟着一个 新脉冲 ( 状态 1) 时才能上电。

热保护

起动器热保护
通过安装在散热器上的 PTC 传感器和计算晶闸管的温升提供热保护。

电机热保护
起动器会根据受控制的额定电流 In 和实际吸收的电流持续地计算电机的温升。 温升可能由长时间或短时间的欠载或过载引起。 下面几页上的脱扣曲线是基于起动电流 Is 和电机电流 In ( 可 调整的 ) 做出的。 IEC60947-4-2 标准定义了保护等级,它给出了电机的无热故障起动能力 ( 热起动或冷起动 )。对 COLD ( 冷 ) 状态 ( 对应于稳定的电机热状态,断电 ) 和 WARM ( 热 ) 状态 ( 对应于一个稳定的电机热状态,在 额定功率下 ) 给出了不同的保护等级。 起动器出厂设置为 10 级保护。 可以使用 PrO 菜单修改保护等级。 起动器显示的热保护对应于加热时间常数 (iron time constant)。 - 如果电机超过了其额定温升阈值 ( 电机热状态 =110%) 则激活过载报警。 - 如果超过了临界温升阈值 ( 电机热状态 =125%) 热故障将使电机停机。 在出现起动延长时,即使显示的值低于脱扣值起动器也能由故障或热报警脱扣。 如果没有禁止热保护,则热故障可以由继电器 R1 指示。 在电机已经停机或起动器已被断电后,即使控制电路断电也仍然会计算热状态。 ATS 热控制系统可以防 止在电机温升过高的情况下重新起动电机。 如果使用特殊的电机 ( 防火、水下的等等 ),则应由 PTC 传感器提供热保护。

ENGLISH

As a rule, the ATS 48 control (CL1 - CL2) and power (1/L1 - 3/L2 - 5/L3) supplies must be disconnected before any operation on either the electrical or mechanical parts of the installation or machine. During operation the motor can be stopped by cancelling the run command. The starter remains powered up. If personnel safety requires prevention of sudden restarts, this electronic locking system is not sufficient: fit a breaker on the power circuit. The starter is fitted with safety devices which, in the event of a fault, can stop the starter and consequently the motor. The motor itself may be stopped by a mechanical blockage. Finally, voltage variations or line supply failures can also cause shutdowns. If the cause of the shutdown disappears, there is a risk of restarting which may endanger certain machines or installations, especially those which must conform to safety regulations. In this case the user must take precautions against the possibility of restarts, in particular by using a low speed detector to cut off power to the starter if the motor performs an unprogrammed shutdown. The products and equipment described in this document may be changed or modified at any time, either from a technical point of view or in the way they are operated. Their description can in no way be considered contractual. This starter must be installed and set up in accordance with both international and national standards. Bringing the device into conformity is the responsibility of the systems integrator who must observe the EMC directive among others within the European Union. The specifications contained in this document must be applied in order to comply with the essential requirements of the EMC directive. The ATS 48 must be considered as a component: it is neither a machine nor a device ready for use in accordance with European directives (machinery directive and electromagnetic compatibility directive). It is the responsibility of the final integrator to guarantee conformity to the relevant standards.

ENGLISH

Wire the fault relay in the line contactor power supply sequence in order to open the electrical circuit in the event of a fault. For further details refer to the application diagrams.

Connect the RUN and STOP commands and if necessary the other terminal inputs/outputs. Stop at 1 (on) and RUN at 1 (on): start command. Stop at 0 (off) and RUN at 1 or at 0: stop command.

4 - Essential information before starting up the ATS 48:
Read the information on the motor rating plate. The values will be used to set parameter (In) in the SEt menu.

5 - Powering up the control part (CL1-CL2) without the power part and without giving the run command
The starter displays: nLP (to indicate that the power is switched off). The ATS 48 starter is factory-configured for a standard application which does not require specific functions. It has motor protection class 10. The settings can be changed by accessing the parameters as described on page 126. In all cases the In parameter must be set to the current value indicated on the motor rating plate.

6 - Powering up the power part (1/L1 - 3/L2 - 5/L3)
The starter displays: rdY (to indicate that the starter is powered up and ready). Send a "RUN" command to start the system.

87

Factory configuration

Factory settings
The ATS 48 is factory-set for the most common operating conditions: ? The ATS 48 is used on the motor line supply (it is not inserted as a delta connection in the motor windings) ? Nominal motor current In: - ATS 48 ???Q: preset for a standard 400 V 4-pole motor - ATS 48 ???Y: preset for NEC current, 460 V motor ? Limiting current (ILt): 400% of the motor current In ? Acceleration ramp (ACC): 15 seconds ? Initial torque on starting (tq0): 20% of the nominal torque

ENGLISH

? Stop (StY): Freewheel stop (-F-) ? Motor thermal protection (tHP): class 10 protection curve ? Display: rdY (starter ready) with power and control voltage present, motor current operating ? Logic inputs: - LI1: STOP - LI2: RUN - LI3: Forced freewheel stop (LIA) - LI4: Forced local mode (LIL) ? Logic outputs: - LO1: Motor thermal alarm (tA1) - LO2: Motor powered (mI) ? Relay outputs: - R1: Fault relay (r1I) - R2: Bypass relay at the end of starting - R3: Motor powered (mI) ? Analog output: - AO: Motor current (OCr, 0 - 20 mA) ? Communication parameters: - Connected via the serial link, the starter has the logic address (Add) = "0" - Transmission speed (tbr): 19200 bits per second - Communication format (FOr): 8 bits, no parity, 1 stop bit (8nl) If the above values are compatible with the application, the starter can be used without changing the settings.

88

Preliminary recommendations

Handling and storage
To ensure the starter is protected before installation, handle and store the device in its packaging.

Handling on installation
The ATS 48 range comprises 6 sizes of device, with various weights and dimensions. Small starters can be removed from their packaging and installed without a handling device. A handling device must be used with large starters; for this reason they are supplied with handling "lugs". The precautions described below must be observed:

ENGLISH

Do not handle the starter by the power rails

Operating recommendations

Available torque
Curves Ts and Is represent the direct line starting of an asynchronous motor. Curve Ta1 indicates the total torque range available with an ATS 48, which is dependent on the limiting current ILt. The progression of the starter is controlled by the motor torque within this range.

Tr: Resistive torque, which must always be less than the Ts1 torque.

ENGLISH

Selecting the soft start - soft stop unit
S1 motor duty corresponds to starting followed by operation at constant load enabling the thermal equilibrium to be reached. S4 motor duty corresponds to a cycle comprising starting, operation at constant load and an idle period. This cycle is characterised by a load factor. The ATS 48 must be selected depending on the type of application ("standard" or "severe") and the nominal power of the motor. "Standard" or "severe" applications define the limiting values of the current and the cycle for motor duties S1 and S4. Caution: Do not use the ATS 48 upstream of loads other than motors (for example transformers and resistors are forbidden). Do not connect power factor correction capacitors to the terminals of a motor controlled by an ATS 48

Standard application
Example: centrifugal pump In standard applications, the ATS 48 is designed to provide: ? in S1 duty: starting at 4 In for 23 seconds or starting at 3 In for 46 seconds from a cold state. ? in S4 duty: a load factor of 50% and 10 starts per hour, with 3 In for 23 seconds or 4 In for 12 seconds or an equivalent thermal cycle. In this case, the motor thermal protection must conform to protection class 10.

Severe application
Example: grinder In severe applications, the ATS 48 is designed for S4 duty with a load factor of 50% and 5 starts per hour at 4 In for 23 seconds or an equivalent thermal cycle. In this case, the motor thermal protection must conform to protection class 20. Current In must not remain at its factory setting but must be set to the value indicated on the motor rating plate. Note: The starter can be oversized by one rating, for example by selecting an ATS 48D17Q for an 11 kW 400 V motor in motor duty S4. To do this, short-circuit the ATS at the end of starting. This permits 10 starts per hour at 3 times In for 23 seconds maximum or equivalent and the thermal motor protection must conform to class 10.

91

Operating recommendations
The ATS 48 Q range (230-415 V) connected in line with the motor or in the motor delta winding
The ATS 48 connected in the motor supply line

The motor connection depends on the supply voltage, which in this example is a star connection.

ENGLISH

The motor connection depends on the supply voltage, which in this example is a delta connection.

Operating recommendations

The ATS 48 connected in the motor delta winding in series with each winding
ATS48???Q starters connected to motors with delta connections can be inserted in series in the motor windings. They are powered by a current which is less than the line current by a factor of √3, which enables a starter with a lower rating to be used. This option can be configured in the Advanced settings menu (dLt = On). The nominal current and limiting current settings as well as the current displayed during operation are on-line values and so do not have to be calculated by the user. The ATS 48 can only be connected in the motor delta winding for ATS48???Q starters. This means that: - only freewheel stopping is possible - cascading is not possible - preheating is not possible

ENGLISH

See the tables on page 94 for more information about starter-motor combinations.

Connection in the motor delta winding

Example: A 400 V - 110 kW motor with a line current of 195 A (nominal current for the delta connection). The current in each winding is equal to 195/1.7 or 114 A. The rating is determined by selecting the starter with a maximum permanent nominal current just above this current, i.e. 140 A (ATS48C14Q for a standard application). To avoid having to calculate the rating in this way, use the tables on page 96 and 97 which indicate the rating of the starter corresponding to the motor power for each application type.

Wiring/RUN - STOP commands

Wiring recommendations
Power
Observe the cable cross-sectional areas recommended in the standards. The starter must be earthed to conform to the regulations concerning leakage currents. When the use of an upstream "residual current device" for protection is required by the installation standards, an A-Si type device must be used (to avoid accidental tripping during power up). Check its compatibility with the other protective devices. If the installation involves several starters on the same line, each starter must be earthed separately. If necessary, fit a line choke (consult the catalogue). Keep the power cables separate from circuits in the installation with low-level signals (detectors, PLCs, measuring apparatus, video, telephone).

Control
ENGLISH
Keep the control circuits away from the power cables.

Functions of the RUN and STOP logic inputs (See application diagram see
page 112)

2-wire control
Run and stop are controlled by state 1 (run) or 0 (stop), which is taken into account at the same time on the RUN and STOP inputs. On power-up or a manual fault reset the motor will restart if the RUN command is present.

3-wire control
Run and stop are controlled by 2 different logic inputs. A stop is obtained on opening (state 0) the STOP input. The pulse on the RUN input is stored until the stop input opens. On power-up or a manual fault reset or after a stop command, the motor can only be powered once the RUN input has been opened (state 0) followed by a new pulse (state 1).

Thermal protection

Starter thermal protection
Thermal protection is provided by the PTC probe fitted on the heatsink and by calculating the temperature rise of the thyristors.

Motor thermal protection
The starter continuously calculates the temperature rise of the motor based on the controlled nominal current In and the actual current absorbed. Temperature rises can be caused by a low or high overload with a long or short duration. The tripping curves on the following pages are based on the relationship between the starting current Is and the (adjustable) motor current In. Standard IEC60947-4-2 defines the protection classes giving the starting capacities of the motor (warm or cold start) without thermal faults. Different protection classes are given for a COLD state (corresponding to a stabilised motor thermal state, switched off) and for a WARM state (corresponding to a stabilised motor thermal state, at nominal power). The starter is factory-set to protection class 10. This protection class can be modified using the PrO menu. The thermal protection displayed by the starter corresponds to the iron time constant. - An overload alarm is activated if the motor exceeds its nominal temperature rise threshold (motor thermal state = 110%). - A thermal fault stops the motor if it exceeds the critical temperature rise threshold (motor thermal state = 125%). In the event of a prolonged start, the starter can trip on a fault or thermal alarm even if the value displayed is less than the trip value. The thermal fault can be indicated by relay R1 if thermal protection has not been disabled. After the motor has stopped or the starter has been switched off, the thermal state is calculated even if the control circuit is not powered. The ATS thermal control prevents the motor from restarting if the temperature rise is too high. If a special motor is used (flameproof, submersible, etc.) thermal protection should be provided by PTC probes.

Thermal protection

Motor thermal protection with PTC probes
PTC probes integrated in the motor to measure its temperature can be connected to the control card terminals. This analog value is managed by the starter. The "PTC probe thermal overshoot" value can be processed and used in two ways: - stop in the event of a fault if the signal is active - activate an alarm if the signal is active. This alarm can be displayed in a starter status word (serial link) or on a configurable logic output. Note: PTC probe protection does not deactivate the motor thermal protection provided by the calculation. Both types of protection can operate in parallel.

This type of stop reduces the risk of water hammer on a pump. - b -: Dynamic braking stop: The starter generates a braking torque in the motor which will slow the motor down if there is considerable inertia. - F -: Freewheel stop: No torque is applied to the motor by the starter. If the starter is connected to "delta in the motor", only stop type F is permitted.

Torque ramp

In the case of overrating the starter (Im motor> Im ATS48), a value of the parameter bSt too high can cause the starter to trip in OCF dLt Starter with delta winding connection on - OFF OFF

This configuration will permit a rating increase of 1.7 in the starter power but does not permit braking or deceleration. - OFF: normal line torque - On: motor with delta winding connection The nominal motor current In is the same as that specified on the motor rating plate and the current displayed corresponds to the line current of the line supply. The nominal current value In (SEt menu) is the same as that specified on the motor rating plate for the delta connection. The starter carries out the conversion itself to control the current in the windings. This parameter can only be accessed for ATS 48???Q starters. ? With this function, only freewheel type stopping is possible ? Cascading is not possible ? Preheating is not possible

Maintenance

Servicing
The ATS 48 does not require any preventative maintenance. It is nevertheless advisable to perform the following regularly: - Check the condition and tightness of connections - Ensure that the temperature around the unit remains at an acceptable level and that ventilation is effective (average service life of fans: 3 to 5 years depending on the operating conditions) - Remove any dust from the heatsink if necessary

Assistance with maintenance
If a problem arises during setup or operation, ensure that the recommendations relating to the environment, mounting and connections have been observed. The first fault detected is memorized and displayed on the screen: the starter locks and relays R1 and R2 change state according to their assignment.

ENGLISH

Clearing the fault
Switch off the starter power supply in the event of a fault which cannot be reset. Wait for the display to go off completely. Find the cause of the fault in order to correct it. Restore the power supply: this clears the fault if it has disappeared. In some cases there may be an automatic restart once the fault has disappeared if this function has been programmed.
