2)
Motor protection
●
Self-locking:
-
SA/SAR 25.1 – 30.1: Output speeds up to 90 rpm (50 Hz), 108 rpm (60 Hz)
-
SA 35.1 – SA 48.1: Output speeds up to 22 rpm (50 Hz), 26 rpm (60 Hz)
●
NOT self-locking:
-
SA 35.1 – SA 48.1: Output speeds from 32 rpm (50 Hz), 38 rpm (60 Hz)
Multi-turn actuators are self-locking, if the valve position cannot be changed from standstill
while torque acts upon the output drive.
Self-locking
Counter gear mechanism for end positions CLOSED and OPEN
Turns per stroke: 1 to 500 (standard) or 1 to 5,000 (option)
Standard:
●
Single switches (1 NC and 1 NO; not galvanically isolated) for each end position
Options:
●
Tandem switches (2 NC and 2 NO) for each end position, switches galvanically isolated
●
Triple switches (3 NC and 3 NO) for each end position, switches galvanically isolated
●
Intermediate position switch (DUO limit switching), adjustable for any position
Limit switching
Torque switching adjustable for directions OPEN and CLOSE
Standard:
Single switches (1 NC and 1 NO; not galvanically isolated) for each direction
Option:
