Equipment Description; Transportation - AUMA SG 05.1 Operation Instructions Manual

1. EQUIPMENT DESCRIPTION

AUMA quarter-turn actuators are high quality electro-mechanical devices. The AUMA Model SG is a
quarter turn electric actuator, designed in accordance with AWWA Standards. Four sizes are
available:
Model
SG 05.1
SG 07.1
SG 10.1
SG 12.1
The power train consists of a single phase or three phase motor, driving through a three-stage
planetary gear set to a worm gear unit, through a splined coupling to the valve stem.
Electrical connections are made either directly to an electrical plug and socket, or a terminal strip in
an integrally mounted NEMA 4 enclosure. Always refer to the proper electrical diagram before wiring.
The convention of "clockwise-to-close" has been used throughout this manual. A "clockwise-to-
open" valve or damper configuration represents a reversal of limit switch and torque switch
position. When setting the limit and torque switches, note on the cover plate that the black area
represents open and the white area represents closed.

2. TRANSPORTATION

Possible damage can be avoided by observing the following items.
• Transport to place of installation in sturdy packing.
• Do not lift the actuator by the handwheel.
• Store in well ventilated, dry room.
• Protect against humidity from the floor by storing on a shelf or on a wooden frame.
• Cover to protect against dust and dirt.
• Apply corrosion protection agent to machined surfaces.
