a．电位器的电阻值为1K2、5K2。

The resistance valve of the potentionmeter is 1kn, 5KO

b．用手柄转动动阀门到全闭位置。

Rotate the valve and reach to close the b compleby with the handle

C．松开电位器，转动动电位器齿轮，用万能表测量4－5接线端子间的电阻值，使4－5的电阻值到

52以下，紧固电位器固定螺钉。（如果是智能型的七线接插件连接时请测量对RV和RS两插插孔的电阻值）

Unclamp the potentionmeter rotate the gear wheel of the potentionmeter measure the resistance valve among4-5wiring sons of end with the universal meter nable the resistance valve of 4-under 50, fasten the potentionmeter fixed screw.(if please measuer the resistance value to RV and RS two jake when being that inbligent Line seven connects the plug-in package connection

注：手动操作时，不能过分超出全开，全关的极限位置，转角过大，会导致其部件的损坏

Note: At the time of manual operation, can t go beyond and is open excessively compleb he terminal b that is closed compleby. the comer is too big, will cause its part s damage

3．机械限位的调整

Adjustment of the mechanism spacing

a．用手柄转动到全开位置

Rotate to compleby opening b with the handle

b．松开锁紧螺母，旋转调整螺钉，使只与机械挡挡块接触，然后反方向旋转螺钉半圈，锁紧螺毋。

Unclamp the locknut, rotate and adjust the screwenable it and machinery block one and keep in touch, then, rotate semi circke of screw, the locknut in the opposite direction

c．同样的方法，可进行全闭位置的机械挡块的调整。

The same b, can close the adjustment of blocking one of machinery of the b compleby.
