Disassembly of Valve, Actuator ❼

Danger
Danger of injury by steam or hot water! ①

• Valve without actuator is open ①, sealing ② is in the actuator.
• It is absolutely necessary to depressurize system prior to any work.
• Carry out disassembly in reverse order as assembly.

Electrical Connection

HIGH VOLTAGE !
Danger of injury and life in case of improper handling!

• Switch off power supply prior to connecting lines.
• The electrical connection must only be performed by an expert electrician.
• To access electrical panel remove the cover first.

Removing the cover ❽

2. Unscrew screw ② and remove cover ③.

Connections

When cover is removed connect lines in accordance with connection diagram, see ❾:

① Connection for:

• STB – Safety Temperature Limiter
• STW – Safety Temperature Monitor
• SDB – Safety Pressure Limiter

Prior to remounting the cover, carry out settings at the actuator, see next section.

Prior to connection it is absolutely necessary to remove the jumper ① – only types AME (-H) 613, 633 with safety return function.

Actuator Settings ❿

Operation

Electrical Manual Adjustment ⓭

• Rotary switch set to “CLOSE“ ① Actuator stem is extended ②:
  After repositioning, turn to “STOP”
• Rotary switch set to “OPEN“ ③ Actuator stem is retracted ④:
  After repositioning, turn to “STOP”
• Rotary switch set to “STOP“
  Actuator stem stays in its last position.
• Rotary switch set to “AUTO“ ⑤ Actuator is controlled via the external controller.

Standard setting
Strictly observe for normal operation.

Mechanical Manual Adjustments ⓮ (only for the actuators AME-H 613)
In case of a power supply failure or a operating fault, the valve may be opened or closed

1. Turn rotary switch to position “CLOSE” ①.
2. Loosen security screw ②.
3. With hook wrench (accessory) retract actuator stem ③:
   VFG .., AFQM opens ④
   VFU 2 closes ④
4. With hook wrench (accessory) extend actuator stem ⑤:
   VFG .., AFQM closes ⑥
   VFU 2 opens ⑥

Prior to switching to automatic operation (AUTO), it is absolutely necessary to completely turn the adjustment nut ⑤ to its stop.

• Tighten security screw ⑦.
• If this is not observed, the valve cannot be closed. (VFU … not be opened).
