M9102-AGA-2S and M9104-xGA-2S Series Electric Non-Spring Return Actuators Installation Instructions

M9104-GGA-2S
The M9104-GGA Series Electric Non-Spring Return
valve actuators require AC 24 V power and a DC 0(2)
to 10 V or 0(4) to 20 mA controller input signal. These
electric actuators include an integrated 48 in. (1.2 m)
long cable. See Figure 10 for proper wiring.
M9104-GGA actuators are factory set for Direct Acting
(DA) mode and for a DC 0 to 10 V input control signal.
In DA mode, a minimum control signal drives the
actuator to the full Counterclockwise (CCW) position,
and a maximum control signal drives the actuator to the
full Clockwise (CW) position.
For Reverse Acting (RA) operation, a minimum control
signal drives the actuator to the full CW position and a
maximum signal drives the actuator to the full CCW
position.
To change the factory settings (DA, 0-10 V), remove
the actuator cover and adjust the switches on the
circuit board as shown in Figure 12.

CAUTION: Risk of Electric Shock.
Disconnect power supply before making
electrical connections to avoid electric
shock.
!
CAUTION: Risk of Property Damage.
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.
IMPORTANT:
Make all wiring connections in
accordance with local, national, and regional
regulations. Do not exceed the electrical ratings of
the M9102 or M9104 Series Electric Non-Spring
Return Valve Actuator.
