Belimo SY-3-T-TS Series Quick start guide

Wiring Diagram
"L" (Live wire) connects to terminal #3 for OPEN.
"L" connects to terminal #4 for CLOSE.
Connect "L" to terminal #7 to activate the internal heater. (No
need to connect internal heating for indoor applications with
constant temperature conditions.)
Note:
1)
"L"
shall
not
connect
to terminal #3 and #4
simultaneously
2) Relays are needed in parallel connection of
several actuators!
3) 30% duty cycle
If it is necessary to change the following settings,
only authorized and trained personnel are allowed
to do so.
Install to butterfly valve
1)
Manual operate the actuator to the
similar open position of the valve,
which can be judged by the valve
disc.
2) Fit coupling on the top stem of the
valve.
3) Mount the actuator onto the
coupling, manual operate the
actuator to align the holes of valve
top flange and actuator bottom;
then tighten the bolts by wrench in
diagonal sequence.
4) Remove the actuator cover, wire
according to the wiring diagram.
5) Power on to test run the actuator,
check its travel angle and feedback
position, make adjustment if
necessary.
6) Put the cover on and tighten the
bolts
Limit switches LS.. with travel cams TC..
Note:
TC1 and TC2 switches are carefully calibrated at factory and
adjustment is normally not needed. Adjustment on these limit
switches must be carried out by trained personnel and wrong
adjustment could damage the system.
The TC.. cams rotate with the shaft, and trigger the LS.. limit
switches. Clockwise movement of the shaft closes the actuator,
counterclockwise movement opens the actuator.
There are 4 cams included, marked with two colors: blue for open,
silver for close; each cam can be set independently.
1. How to adjust the travel
cam
1.1. Loosen the cam to be
adjusted with a
2.5mm allen key;
1.2. By turning the key,
rotate and adjust the
cam as shown in the
diagram on the right;
1.3.
Check if the valve can open and close properly
1.4. Tighten the cam after successful adjustment
2. Closed position (0%) setting
2.1. Connect power to terminal #1 and #4.
2.2. Power on. The actuator will drive CW to fully closed
position.
2.3. Adjust travel cam TC2 in the closed position.
2.4. Check whether LS2 switch trips prior to manual
operation stop. (When motor stops at fully closed
position, it should be possible to further operate the
handwheel CW ½…¾ turn. Otherwise the stop screw for
manual closed limit need to be adjusted.)
3. Adjust similarly for TC1 in open position by connecting power
to terminal #1 and #3.
Limiting of manual rotation with top screws
Note: Top screws for manual OPEN and CLOSE limit are carefully
calibrated at factory and adjustment is normally not needed.
Adjustment on these screws must be carried out by trained
personnel and wrong adjustment could damage the system.
SY quarter-turn actuator is provided with a limiting of manual
rotation device to avoid over-travel with the handwheel going
beyond the ¼-turn rotation.
The actuator is supplied and tested for 90⁰ electrical operation, and
-2⁰…92⁰ limiting of manual rotation.
The limiting of manual rotation is realized by the stop screws 1 and
2 (max. ±2⁰ which corresponding to 1 turn of the stop screw).
The top screws must be secured
with the lock nut after any
adjustment. (by both an allen key
and a wrench)
The 90⁰ travel must always be
limited by the travel limit
switches so they must be set to
trip just BEFORE contacting the
Stop screws.
To achieve this, loose stop screws by 2½ turns. After travel limit
switch setting is completed, operate the actuator electrically to
closed position. (See paragraph Limit switches LS.. with travel
cams TC..) Now rotate the stop screw 2 to closed position, re-
loosen 1 turn, and secure by lock nut. Proceed in the same way for
stop screw 1 in open position. The limiting of manual rotation
device is only a design feature to prevent over-travel when the
actuator is being operated manually, it is not a safety function to
prevent over-travel in the event of travel limit switch failure.
Overload protection
This actuator is equipped with a torque switch that breaks the
power when an overload condition appears. An alarm switch will
be triggered when the torque limit switch activates.
TS3: When the torque value is overloaded, terminal #8 will loop to
terminal #9 when actuator turns counterclockwise.
TS4: When the torque value is overloaded, terminal #11 will loop to
terminal #12 when actuator turns clockwise.
Auxiliary switch for closed (factory setting 3⁰)
Auxiliary switch for open (factory setting 87⁰)
Closed switch (factory setting 0⁰)
Open switch (factory setting 90⁰)

接线说明
L(火线)与端子#3 连接为打开
L 与端子#4 连接为关闭
L 与端子#7 连接，激活内置电加热（恒温的室内应用中，无需连
接内置电加热。）
注: 1) 禁止将"L"与#3 和 #4 端子同时连接。
2) 当多个执行器并联连接时需于接线点加继电器！
3) 30% 工作频率
只有经过培训和授权的人员才允许改变以下设置
与蝶阀安装
1) 根据阀板所指示位置，将执行器
手动打开至该位置。
2) 将连接件套在阀轴顶端。
3) 将执行器套上连接件，之后手动
操作执行器使阀门上法兰螺栓孔
与执行器下方安装孔对齐，然后
通过扳手将螺栓按对角线顺序紧
固。
4) 拆下执行器上盖，按接线说明接
线。
5) 给执行器通电并试运行，检查运
行状况与反馈位置，需要时调
整。
6) 装好上盖并紧固螺栓。
电子行程开关 LS.. 与行程凸轮 TC..
注意:TC1 和 TC2 开关在出厂前经过仔细校准，通常不需要调整。
必须由经过培训的人员对这些限位开关进行调整，调整不当可能会
损坏系统。
行程凸轮 TC.. 随轴的转动并使电子行程开关 LS.. 动作。 轴顺时针
方向转动时执行器关闭，逆时针转动时执行器打开。 共有 4 个行程
凸轮，以两种颜色标记：蓝色表示控制打开，银色表示控制关闭；
任何一个凸轮都可以单独调整。
1. 如何调整行程凸轮
1.1. 将 2.5 mm 内六角扳手
插入所要设定的行程凸
轮 的 螺 孔 内 ， 松 动 螺
栓。
1.2. 用内六角扳手按图所示方法调 整行程凸轮位置，并预拧
紧螺丝。
1.3. 检查阀门是否能正常开或关。
1.4. 成功调整完毕后必须锁定行程凸轮。
2. 关闭位置(0%)设定
2.1. 端子 #1, #4 连接电源;
2.2. 通电，执行器会顺时针转动至全关位置。
2.3. 调节行程凸轮 TC2 至全关位置。
2.4. 检查电子限位行程是否在机械限位范围之内。(即马达
于 全 关 位 置 停 止 后 ， 逆 时 针 方 向 操 作 手 轮 能 旋 转
1/2...3/4 圈， 否则需调整止附螺栓。)
3. 端子#1 和#3 连接电源，通电后，对 TC1 开启位置(100%)通
过上述步骤进行设定。
机械限位
注意:手动开/关的止附螺栓在出厂前经过仔细校准，通常不需要调
整。 必须由经过培训的人员对止附螺栓进行调整，调整不当可能
会损坏系统。
SY 执行器具有机械限位。
执行器经过测试只提供 90°电子限位行程以及-2°...92°的机械限位
范围。 机械限位由止附螺栓 1 和止附螺栓 2 控制(转动止附螺栓 1
圈相当于最多 2°)。
止附螺栓被调整后必须紧固螺母
(通过一个内六角与一个扳手) 电
子行程必须被设定在 90°以内 并
在机械限位范围之内。
当电子行程设定结束后， (参见：
电子行程开关 LS.. 与行程 凸轮
TC.. 部分)可将止附螺栓 拧松 2 圈
半左右，然后通电运转执行器到
全关位置。
将止附螺栓 2 顺时针旋至尽头后，再逆时针转 1 圈，紧固螺母。
对于止附螺栓 1 请重复上述操作。 需要强调的是 SY 执行器机械限
位仅为了避免手轮过度转动，而不可替代电子行程开关的作用。
过扭矩保护
该执行器配有一个扭矩开关，当出现过载情况时，该开关切断电
源。 当扭矩限制开关启动时，警报开关将被触发。
TS3: 当扭矩值过载时，端子#8 与端子#9 导通(出厂默认为逆时针
方向，阀门打开)。
TS4: 当扭矩值过载时，端子#11 与端子#12 导通(出厂默认为顺时
针方向，阀门关闭)。
