Calibration/校准
In order to determine the disc position fully closed "0 %" or fully open "100 %", cali-bration is recommended on initial
en
commissioning of modulating type actuator.
为确定阀板位置处于完全关闭"0 %"状态或完全打开"100 %"状态,建议在模拟量控制执行器初次调试时进行校

准。
Calibration
1. Supply power to ter-
minal 1 and 2.
2. Press button S1 for 3
seconds
3. Calibration finished.
Note: When doing the Calibration procedure, the position of the cam calibration shall be already done (refer to cam adjustment).
校准
1.接通电源.
2. 按住 S1 保持 3 秒
3. 校准完成
在凸轮校准完成后,再做执行器校准。
