Indication lights
The colours of the 3 indication lights on the local controls and the assignment of the
signals are specified in the order.
Figure 31:
Local controls with indication lights (default signalling)
[1]
illuminated (green): End position OPEN reached
[2]
illuminated (red): Collective fault signal
[3]
illuminated (yellow): End position CLOSED reached
Collective fault signal
The collective fault signal (red indication light) will be activated if one of the following
events occurs (default configuration):
●
Torque fault: The set torque was exceeded before reaching an end position.
(This signal can be activated/deactivated via a switch in the controls.)
●
Thermal fault: Motor protection has tripped, i.e. the motor is overheated.
●
Phase failure: One phase is missing (3-ph AC motors only).
●
PTC tripping device: Test complete
Running indication
If the actuator is equipped with a blinker transmitter (wiring diagram designation:
S5), indication lights [1] and [3] can be used as running indication. The running
indication can be activated/deactivated via a switch in the controls. If the running
indication is active, the respective indication light blinks during operation.
7.2
Mechanical position indicator/running indication
— Option —
Mechanical position indicator:
●
Continuously indicates the valve position
(For complete travel from OPEN to CLOSED or vice versa, the indicator disc
[2] rotates by approximately 180° to 230°.)
●
Indicates whether the actuator is running (running indication)
●
Indicates that the end positions are reached (via indicator mark [3])
