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, check the DIP switch
setting.
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.

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).

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
2.2 Power on.
The actuator will stop .
2.3
Adjust travel cam TC2 in the closed position.
Check whether LS2 switch trips prior to manual operation stop.
(The fanshaped cam which connected with the potentiometer need
to be loosed firstly, then retightened after the travel limit switches
setting is terminated.)
( 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.

1. 如何调整行程凸轮
调整过凸轮位置后需执行一次
“daption” 自适应 。
1.1 将 2.5 mm 内六角扳手插入所要设定
的凸轮的螺孔内，松动螺栓。
1.2 用内六角扳手挑动凸轮，按左图
所示方法调整凸轮位置，并预拧
紧螺丝。
1.3 通电检查限位开关 LS 的动作是否
使阀板到位。
1.4 成功调整完毕后，务必锁定凸轮。

2.3
调节行程凸轮TC2至全关位置。
检查电子限位行程是否在机械限位范围之内。
(在调节前将与电位计相连的凸轮先松开，待调整过程成功
完成后再紧固。)
(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。

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
( 转动限位螺栓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。

2- “全关”止附螺栓
3- 连接手轮，用于手动操作
