Technical conditions for SG actuators installation.
•
Mechanical installation of SG actuator consists of mounting the actuator to the
drive console and connecting the actuator eye bolt with a MHV hook lock. It is very
important to adjust this connection. The proper adjustment ensures reliable
latching of the MHV lock on a T fitting, and at the same time turning the actuator
off by the limit switch, not the overload switch.
