1 安全须知

本装置符合现行安全标准。

本装置的安装、维护和使用只能由经过培训的技术人员实施。

安装和调试之前，请仔细阅读全文。.

2 阀门安装

执行器应采用合适的螺栓及连接装置直接紧固到阀门上。

执行器可于任何方向安装，但电缆接口不得朝上，以免造成漏水。

电机最好不要位于下方，以防内部的冷凝水进入电机。

注意 1 : 搬动执行器时请勿将手轮当把手，以免造成蜗杆损坏。

注意 2 : 如果执行器在交货时已经安装于阀门，则基本设定应已完

成。此时只需参考第3，4和9章节即可。

注意 3 : 调试前的存放注意事项，参见第9章节。

3 手轮操作

通常情况下，手轮在电动操作过程中不会转动。

即使转动，实心手轮上没有任何凸起物，因此不会对操作者构成伤

害风险。

而且，对于大扭矩的执行器来说，扭矩限制系统还提供了多重保

护。

SQ4 到 SQ15:

这类执行器配有手动离合手轮。

要手动操作执行器，请一边旋转手轮一边将其拉出，实现手轮的机

械啮合。

要使手轮脱开，只需朝向执行器体，将手轮推回即可。

SQ100,SQ250 到 SQ1000:

此类执行器均配备电动优先型自动离合手轮。手动操作执行器时，

旋转手轮离合器旋钮，将箭头对准箱体上的三角符号即可（必要时

稍微转动手轮，以便离合器啮合）。当电机启动时，手轮自动返回

到脱离位置。

警告

在防爆执行器安装和调试之前，还请仔细阅读TMS1132

特别说明。

Chinese

SQ25/SQ60/SQ80 型号:

这些执行器中，部分配有可离合的中间齿轮。通过拨动离合器拨

杆，电机即可与齿轮系统物理脱离。手动手轮操作完毕后，记住要

把电机离合复位。否则，在启动后，电机就会持续运行并发热，直

到电机热保护开关动作为止，如果反复发生这种情况，就会造成电

机损坏。

4 电气连接和初检

如果执行器配有 INTELLI+®, INTEGRAL+, POSIGAM, MINIGRAL 或 MINIGAM

控制装置，请参考相应的说明手册进行接线。

其它情况下，执行器的所有电子元器件均连接至一个公共端子板。

打开机壳，将电缆从电缆接口 (M20). 穿入，具体的端子编号系统，

请参考接线图。

扭矩和行程开关必须和用户的控制系统接好（见接线样例），以防

将来造成执行器或阀门的损坏。.

必须检查以下各项:

确保电源电压与执行器铭牌上刻印的数据相符。

b) 检查所有电缆接口是否正确紧固。

c) 用手将阀门转到半开位置。

d) 进行电动开阀操作，检查电机旋转方向是否正确。用手按下“

开阀”行程限位开关，电机应停止运行。

以同样的方法检查电动关阀命令，以及“关阀”行程限位开关

工作是否正常。

e) 除 SQ4 到 SQ15之外的其他型号：进行电动开阀操作。用手按

下“开阀”扭矩限位开关，电机应停止运行。

以同样的方法进行电动关阀操作，检查“关阀”扭矩限位开关工作

是否正常。

本阶段如发现故障，则请检查整个接线。

为提高工作条件的安全性，我们建议立即切断电源，尤其是对扭矩

输出超过300 N.m. 的执行器，更应如此。

5 机械限位与行程限位开关的设定

机械限位相关说明与功能介绍（仅限角行程执行器）:

这些机械限位可防止手轮操作过程中发生过行程现象。

这些限位既可安装于执行器上，也可安装于角行程蜗轮蜗杆齿轮箱

上（如有）。

执行器和齿轮箱均按照90°行程供货和检验。通过调节机械限位螺

栓，可进行最大± 2°的微调。

行程限位开关相关说明与功能介绍:

操作限位开关的凸轮组件位于一个圆柱体上，无需拆解。各凸

轮之间可相互独立设置，白色和黑色凸轮一般用于开阀和关阀

方向行程限位开关，其它则留给选配的附加限位开关 ( 2 或 4 )使

用。

凸轮设定方法:

将螺丝刀插入按钮的槽内（按钮上的色圈与待设定的凸轮同

色）。

b) 轻轻下压，让凸轮脱离锁定位置。

c) 转动螺丝刀，将凸轮旋转到能够触发限位开关为止。

d) 松开螺丝刀，确保按钮回到原位，从而将凸轮锁定到所设位置。

机械限位和行程限位开关的设定步骤：

将机械限位螺栓旋松2圈

b) 手动操作将阀门打到关阀位置。对角行程执行器来说，如果尚

未完成关阀，就已达到了机械限位，则表明行程已超出了所允

许的最大2°调整范围，切勿试图超越此限制，应重新调整执行

器与阀门的安装位置。

c) 设定“关阀”行程限位开关的凸轮。

d) 顺时针旋转机械限位螺栓，直到有机械接触为止。然后旋松1.5

圈，用锁定螺母锁定。

按照相同的方式进行开阀限位设定。

进行电动全开全关操作。必须确保电机停在行程限位开关设定位

置，而不是机械限位设定位置（继续转动手轮，检查到机械限位是

否还有额外行程）。

6 扭矩限位开关的设定

重要事项：

伯纳德控制执行器的扭矩限制开关，在设计上只提供瞬

时接触，但可按照要求，在执行器上装配能保持这种接触的继电

器。

执行器的设定和测试均应按照订单中要求的扭矩进行。如未规定扭

矩，则执行器在供货时，扭矩弹簧设定为最大输出（参见技术手

册）。

如果必要，可通过调整扭矩弹簧压紧螺母，重新调整这一扭矩限

制。通过压紧或松开螺母，即可增大或减小扭矩限制。具体请与我

们联系。

7 位置反馈电位计（选配）

执行器位置信号反馈电位计由行程凸轮组驱动。

电位计无机械限位，并且在行程起点和终点各有一段零电阻区（或

称死区）。0%位置对应阀门关闭，100%对应阀门开启。

电路板安装版本

在将电位计组件安装到开关板上时，要先卸下凸轮组顶端的位置指

特别存放环境潮湿时更应如此（除另行规定外，标准电压均为交

流230伏）。

配备有电子元件的执行器的存储:

电子元件长期存放不用，其故障风险会有所加大。因此，这种做法

非常不可取。

如果确实有必要长期存放，则强烈建议在使用执行器之前将电路板

返厂检测。

存放后的控管:

对电气设备进行外观检查,

手动操作微动开关、按钮、选择器等，确保机械功能正常,

SQ100/SQ250/SQ400

10 11

English

SQ25/SQ60/SQ80 models:

Some of these actuators are equipped with declutchable intermediate

gears. By moving the clutch lever, the motor is physically disengaged from

the gears. Once the manual handwheel operation has been completed,

do not forget to clutch the motor back. Otherwise, once started-up,

it would run and heat up until the motor thermal protection switch closes.

If repeated, these conditions can generate a motor breakdown .

4 ELECTRICAL CONNECTIONS AND PRELIMINARY TESTS

If the actuator is equipped with INTELLI+®, INTEGRAL+, POSIGAM, MINIGRAL

or MINIGAM commands, please report to the speciﬁc documentation for wi-

ring details.

Otherwise, all components of the actuator are wired to a common

terminal strip. Remove the cover and pass the cables through the cable

glands (M20). Refer to the wiring diagram for details on the terminals

numbering system.

Both torque and travel limit switches must be integrated into your

control system (see wiring examples) in order to prevent potential

damage to the actuator or valve.

The following points must be checked:

Make sure that power supply voltage is in accordance with the data

engraved on the actuator nameplate,

Check that all cable glands are correctly tightened,

Move the valve manually to an half-open position,

Operate an electrical opening and check that the motor rotates

in the right direction. Press manually on the «OPEN» travel limit

switch ; the motor should stop.

In the same way, check that the closing electrical command as well as

the «CLOSED» travel limit switch are working correctly,

All models except SQ4 to SQ15: operate an electrical opening. Press

manually on the «OPEN» torque limit switch ; the motor should

stop.

In the same way, operate an electrical closing check that

the «CLOSED» torque limit switch is working correctly,

If any misfunction was detected at this stage, please check the overall

wiring.

For safer working conditions, we recommend that the power supply now

be switched off especially if the actuator output max. torque exceeds

300 N.m.

1 SAFETY INFORMATION

This device complies to current applicable safety standards.

Installation, maintenance and use of this apparatus will have to be done

by skilled and trained staff only.

Please read carefully the whole document prior to mounting and starting-up.

2 ASSEMBLY

Actuator should be secured directly to the valve using proper bolts or via

a proper interface.

After assembly, the actuator can operate in any position. However, cable

glands should not be oriented upwards (loss of water tightness) and the

motor will preferably not be positioned at the bottom (potential internal

condensation trap)

Note 1 : do not handle the actuator by handwheel, it could damage

the gearworm.

Note 2 : if the actuator was delivered mounted on the valve, the basic

settings should have been done. In this case, refer to § 3,4 and

9 only.

Note 3 : see §.9 for details on storage precaution prior to starting-up.

3 HANDWHEEL OPERATION AND DECLUTCHING

In general, the handwheel does not turn during electrical operation.

Even if turning, the solid handwheel does not have any protruding part

and therefore does not present any risk of any kind for the operator.

Moreover, for the actuators with the highest torque, the torque limit sys-

tem brings an additional level of protection.

SQ4 to SQ15:

These actuators are equipped with a manually declutchable handwheel.

To operate manually the actuator, turn while pulling the handwheel

in order to mechanically engage it.

To declutch the handwheel, just push it back towards the actuator body.

SQ100, SQ250 to SQ1000:

These actuators are provided with an automatic declutching handwheel,

with motor drive priority. In order to operate manually the actuator, turn

the arrow of the handwheel clutch button in front of the triangular sign

on the housing (it might be necessary to turn the handwheel by a few

degrees to release the claws). When the motor starts, it returns automati-

cally into declutched position.

WARNING

For explosionproof actuators, please also read carefully the special

instructions TMS1132 prior to mounting and starting-up

12 13

English

6 SETTING OF TORQUE LIMIT SWITCHES

IMPORTANT: the torque limit switch design of Bernard Controls actua-

tors gives a short duration contact only. On request, relays holding this

contact maintained can be ﬁtted into the actuator.

Actuators are set and tested in accordance with the torque stated

on orders. If no torque is speciﬁed, the actuator is supplied with torque

springs set to the maximum output (refer to our catalogue technical da-

tasheets).

If necessary, this torque setting can be readjusted by rotating the nuts

which compress the torque springs. So the torque can be increased

or decreased by tightening or loosening the nuts. Please consult us.

7 POSITION FEEDBACK POTENTIOMETER (OPTION)

The potentiometer used for actuator signal feedback is driven by the travel

cam block system.

The potentiometer has no mechanical stop and has a non-resistive area

(dead zone) at both the beginning and end of track.

0% position corresponds to a closed valve. 100% to an open valve.

Circuit board mounted version

To mount the potentiometer device on the switch plate, clip it without

the position indicator on the camblock and screw it on the support

column. Screw the position indicator back.

Setting of potentiometer zero is achieved thanks to the «0% postion»

screw.

Drive the actuator to the closed position.

Resistance value is measured between terminals 16 and 17.

Hold the pinion located just under the plate with the «0% position»

marking while driving the potentiometer screw. Adjust the potentiometer

so that the resistance value exceeds 0 Ohm and regularly increases then

turn backwards to reach a value as close to 0 Ohm as possible.

Drive the actuator to the open position and write down the resistance

value corresponding to the 100% position.

Come back to the closed position and check that, for the 0% position, the

resistance shows a close to zero repeatable value.

On support column mounted version (SQ4 to SQ15)

To mount the potentiometer device, screw the support column on the mounting

plate and engage the driving pinion into the camblock wheel.

To adjust the potentiometer resistance value, loosen the nut with the wrench

and rotate potentiometer until the signal requested is archieved.

To set the 0%, drive the actuator to the closed position.

Resistance value is measured between terminals 16 and 17.

Rotate the potentiometer so that the resistance value exceeds 0 Ohm

and regularly increases then turn backwards to reach a value as close to

0 Ohm as possible.

Retighten nut after setting.

5 SETTING OF MECHANICAL STOPS AND TRAVEL

LIMIT SWITCHES

Mechanical stops description and function (1/4 Turn only):

These items avoid any over-travelling during handwheel operations.

The stops can be positioned either on the actuator itself or on the 1/4 Turn

worm gearbox if any.

Actuators and gears are supplied and tested for a 90° operation.

Fine adjustment of the stop screws position is possible within a limit

of ± 2° maximum.

Travel limit switches description and function:

The cams operating the limit switches are on a cylindrical block which

does not require any disassembly. Each cam can be set independently of

the others. The white and black cams are for open and close travel limits.

The other ones are for additional limit switches for signalisation (2 or 4).

How to operate the cams:

Put a screwdriver in the slot of the button encircled by the same

color as the cam to be set,

Press lightly to disengage the cam of locked position,

By turning the screwdriver rotate the cam to the position in which

it can trip the limit switch,

Remove screwdriver and ensure that the button has come back to

its original position, thus locking the cam in chosen place.

Procedure of mechanical stops and travel limit switches setting:

Loosen stop screws by 2 turns.

Manually drive the valve to the closed position. If mechanical stops

are reached before the valve closing is completed, it means that the

2° maximum adjustment tolerance has been exceeded ; do not try

to go beyond this limit.

Set the cam of the «CLOSED» travel limit switch.

T urn stop screws clockwise to the mechanical contact, reloosen

1.5 turn, and secure by lock nut.

Proceed in the same way in open position.

Perform complete electrical valve opening and closing operations.

It is mandatory that the motor stops on the travel limit switch and not

on the mechanical stop (check available extra travel to the stop with

handwheel).

14 15

English

Settings

Connect a milliampermeter at the place of burden.

Always start by adjusting the 0/4mA.

Drive actuator to the position corresponding to the 0/4 mA (closed

in standard),

Hold the pinion located just under the plate with the «0% position»

marking while driving the potentiometer screw. Adjust the poten-

tiometer so that the output current reaches a minimum value. Turn

backwards until the current value regularly increases then turn

backwards again and stop as soon as the minimum value determined

here above has been reached.

The potentiometer is then positioned at the very beginning of its track.

Then, use the TAM adjustment screw marked as «0/4mA» to adjust

the current to a value as close to the 0/4 mA as possible.

Drive actuator to the position corresponding to the 20 mA (open

in standard),

Turn the screw marked «20mA» in order to read exactly 20 mA

on the milliampermeter.

Come back to the closed position and check that, for the 0% position,

the signal current shows a close to 0/4 mA and repeatable value.

9 MAINTENANCE AND STORAGE INSTRUCTIONS

Maintenance

If actuator is correctly mounted and sealed, no special maintenance is

required. Check once a year function of motor and make sure that switch

compartment is condensation free. If environment is humid, in oder to

avoid condensation BC electric actuator have installed anti-condensa-

tion heater resistance inside the enclosure.

Storage

The actuator includes electric equipment as well as grease lubricated gear

stages. In spite of the weatherproof enclosure, oxydising, jamming and

other alterations are possible if actuator is not correctly stored.

Actuators stored in a stock room

The actuators should be stored under a shelter, in a clean and

dry place and protected from wide temperature variations. Avoid

placing the actuators directly on the ﬂoor.

For actuators equipped with an heating resistance, it is recom-

mended to connect and power supply it especially if the storage

area is humid (standard 230 VAC, unless other speciﬁcation).

Check that the temporary sealing plugs of the cable entries are well

in place. Make sure that the covers and the boxes are well closed

to ensure weatherproof sealing.

Actuators installed but waiting for electrical connection

If a long period of time is expected between the actuator mounting and

the electrical wiring works :

Visually check the tightness of electrical box cover and cable glands.

Cover the device with a plastic protective ﬁlm.

For actuators equipped with an heating resistance, it is recom

Drive the actuator to the open position and write down the resistance

value corresponding to the 100% position.

Come back to the closed position and check that, for the 0% position, the

resistance shows a close to zero repeatable value.

Note: If actuator is equipped with 2 potentiometers, each potentiometer

is set independently of the other.

Signal inversion:

To inverse the signal variation direction, invert potentiometer wires

on the actuator terminal board (e.g. for a connection on 16/17/18, invert

16 and 18).

8 «TAM» POSITION TRANSMITTER (OPTION)

The TAM transmitter delivers a 0/4 to 20 mA signal linearly proportional

to the angular position of the valve.

Electric connections

Refer to the wiring diagram supplied with the actuator. See also some

typical wiring examples below.

Filtered or stabilised power supply should be provided within the 12 to

32 VDC range.

Maximum admissible ohmic load values are given in the table :

Signal direction inversion

The TAM transmitter, when supplied with a standard actuator, provides

a signal that rise from close position to open position, the standard

opening direction being counter-clockwise.

If an opposite signal variation is required, simply move 2 jumpers on the board

near the potentiometer.

Direct signal : jumpers on 1-3 and 2-4

Reversed signal : jumpers on 1-2 and 3-4

mended to connect and power supply it especially if the storage area

is humid (standard 230 VAC, unless other speciﬁcation).

Storage of actuators equipped with electronic components:

Long term storage of electronic components which are not in service increases

the malfunction risk. This practice is therefore highly unadvisable.

If a long term storage is absolutely necessary, we strongly recommend

a revision of the electronic boards in our factory before actuator usage.

Control after storage:

Visually check the electric equipment,

Operate manually the microswitches, buttons, selectors, etc., to insure

the correct mechanical function,

Operate apparatus manually,

Verify the correct grease consistency,

For actuators equipped with grease nipple, remember to complete

with some fresh grease.
