Product Usage Instructions

Safety Note

• To avoid injury of persons and damages to the device, it is absolutely necessary to read and observe these instructions carefully.
• Necessary assembly, start-up, and maintenance work must be performed by qualified and authorized personnel only.
• Please comply with the instructions of the system manufacturer or system operator.

Mounting 1
The actuator should be mounted with the valve stem in either horizontal position or pointing upwards. The actuator is fixed to the valve body by means of a ribbed nut which requires no tools for mounting. The ribbed nut should be tightened by hand.

Wiring 2
Do not touch anything on the PCB.

Installation 3

1. Check the valve’s neck. The actuator should be in stem-up position (factory setting). Ensure that the actuator is mounted securely on the valve body.
2. Energize the actuator according to the wiring diagram.
3. The direction of stem movement can be observed on the position indicator ❸①.

Manual override 4
(for service purposes only)

Caution: Do not manually operate the drive under power!

Procedure:

• Remove the cover ①.
• Press and hold the button ② (on the bottom side of the actuator) during manual override ③.
• Place cover back on the actuator ④.
• Install actuator on valve ⑤.

Remark:

• A click after energizing the actuator indicates that the gear wheel has jumped into normal position.
• Don’t dismount the actuator from the valve when it is in a stem down position!
• If dismounted in a stem down position, there is a high risk that the actuator gets stuck.

Dimensions 5
Avoid touching anything on the PCB. Follow the hazardous substances table for part materials.

• O: Indicates that the hazardous substance is below the limit requirement in GB/T 26572.
• X: Indicates that the hazardous substance exceeds the limit requirement in GB/T 26572.
