Wiring diagram
Note: 1) "L1" cannot connects to terminal #3 and #4
simultanenously.
2) Relays are needed in parallel connection of several
actuators!
3) 30% duty cycle

Install to butterfly valve
Manual operate the actuator
to the similar open position
of the valve, which can be
judged by the valve disc or
the red line on the valve top
stem.
Fit coupling on the top stem
of the valve.
Mount the actuator onto the
coupling, manual operate
the actuator to align the holes
of valve top flange and actu-
ator bottom; then tighten the
bolts by wrench in diagonal
sequence.
Uncover the actuator, wire
according to the wiring diag-
ram.
Power on to test run the
actuator, check its stroke
and feedback position, do
some adjustment if necessary.
Put the cover on and tighen
the bolts for it.

with a 2.5 mm allen key;
1.2 By turning the key rotate and
adjust the cam as shown in
the right diagram;

Limiting of manual rotation with stop screws
SY quarter-turn actuator is provided with a limiting of manual rotation
device to avoid over-travel with the handwheel going beyond the 1/4-turn
rotation.
The actuator is supplied and tested for 90°electrical operation, and -2°
...92° limiting of manual rotation.
The limiting of manual rotation is realized by the stop screws 1and 2
( max. ± 2° which corresponding to 1 turn of the stop screw).
eg. SY1..~SY12..
Open
Close
If it's necessary to change the following settings, only
authorized and trained persons are allowed to do that.
!
Limit switches LS.. with travel cams TC..
The TC.. cams operating the LS.. limit switches rotate with the shaft.
Clockwise movement of the shaft closes the actuator, counterclockwise
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- Stop screw for manual OPEN limit
2- Stop screw for manual CLOSED limit
3- Handwheel connection
(Note: SY1 without the device)
The stop screws must be sec-
ured with the lock nut after any
adjustment. (by both a allen key
and a wrench)
The 90° travel must always be
limited by the travel limit sw-
it ches so they must be set to
trip just BEFORE stop screw's
contact. To achieve this, loose
stop screws by 2 1/2 turns. Then,
after travel limit switch setting is
terminated, (see paragraph
Limit switches LS.. with travel cams TC..), operate the actuator elect-
rically to closed position. Now rotate the stop screw 2to closed position,
re-loose 1 turn, and secure by lock nut. Proceed in the same way for stop
screw 1in open position.
It is emphasized that the limiting of manual rotation device is only a design
feature to prevent over-travel when the actuator is being operated manually,
not a safety function to prevent over-travel in the event of travel limit
switch failure.
2. Closed position (0%) setting
2.1 Wiring on terminal #1, #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.
( So when motor stops at fully closed position, it should be
possible to further operate the handwheel CW 1/2...3/4 turn.
Otherwise the stop screw for close need to be adjusted.)
Proceed in the similar way for TC1 in open position.

与蝶阀安装
根据阀板或阀轴顶端红线所指示
位置，将执行器手动打开至该
位置。
将连接件套在阀轴顶端。
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。
拆下执行器上盖，按接线说明
接线。
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。
装好上盖并紧固螺栓。

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 用内六角扳手按右图所示方法调
整行程凸轮位置，并预拧紧螺丝。
1.3 通电检查电子行程开关 LS 的动作
是否使阀板到位。
1.4 成功调整完毕后必须锁定行程凸轮。

机械限位
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°)。

1- “全开”止附螺栓
2- “全关”止附螺栓
3- 连接手轮，用于手动操作
(注: SY1无手动限位装置)
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。
2. 关闭位置 (0%) 设定
2.1 连接端子 #1, #4;
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。)
调整全开位置方法与上述类似。
