7.4. Optional indications
7.4.1. Mechanical position indication (self-adjusting)
Figure 62: Mechanical position indicator
[1] End position OPEN reached
[2] End position CLOSED reached
Characteristics
●
Independent of power supply
●
Used as running indication: Indicator disc (with arrow ) rotates during actu-
ator operation and continuously indicates the valve position
(For “clockwise closing version”, the arrow rotates in clockwise direction for

Arrow points to symbol (OPEN) or (CLOSED)
●
Self-adjusting upon commissioning
(The cover does not have to be opened)
7.4.2. Mechanical position indication via indicator mark
Figure 63: Mechanical position indicator
[1] End position OPEN reached
[2] End position CLOSED reached
[3] Indicator mark at cover
Characteristics
●
Independent of power supply
●
Used as running indication: Indicator disc rotates during actuator operation and
continuously indicates the valve position
(For “clockwise closing version”, the symbols / rotate in counterclockwise
