M9208-GGx-x Series Proportional Electric Spring Return Actuators Installation Instructions8
Using Conduit
All M9208 Series Actuators accept 3/8 in. trade size
flexible metal conduit.
1. Feed the actuator cables through the field supplied
conduit.
2. Push the conduit into the holes in the actuator and
secure it with the supplied 10-32 x 9/16 in. screws,
as illustrated in Figure 12. The product label marks
the position of holes for the screws. Drive the
screws through the product label in the marked
positions. Drive the screwhead flush with the plate
to secure the conduit.
Setup and Adjustments
Mode Selection Switch
Actuators have an external mode selection switch to
calibrate, select input signal range, and reverse control
logic. The switch is accessible from both A and B sides
of the actuator as illustrated in Figure 13. Actuators are
delivered in Direct Acting (DA), DC 0 to 10 V input
signal mode. To change to Reverse Acting (RA) mode,
move the mode selection switch from DA to RA. The
input signal range is selectable between DC 0 to 10 V
or DC 2 to 10 V. If the CAL function is not used, both
input signal ranges are proportioned across the full
rotation range of 0 to 95° rotation.
For example, if a DC 0 to 10 V input signal is selected
and the rotation range is limited to 75°, the rotation
range limit will be reached at DC 8.3 V.
!
WARNING: Risk of Electric Shock.
Disconnect or isolate all power supplies
before making electrical connections.
More than one disconnect or isolation
may be required to completely
de-energize equipment. Contact with
components carrying hazardous voltage
can cause electric shock and may result
in severe personal injury or death.
!
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.
!
CAUTION: Risk of Property Damage.
Insulate and secure each unused wire
lead before applying power to the
actuator. Failure to insulate and secure
each unused wire lead may result in
property damage.
IMPORTANT: Make all wiring connections in
accordance with the National Electrical Code and
local regulations. Use proper Electrostatic Discharge
(ESD) precautions during installation and servicing
to avoid damaging the actuator’s electronic circuits.
Figure 12: Adding Flexible Metal Conduit
IMPORTANT: Careful workmanship is required to
secure flexible metal conduit. Cut the conduit end
perpendicular to its axis. Insert the cut end into the
bottom of the holes in the actuator and hold the
conduit in place while securing it with the screws
provided. Check a completed installation by pulling
on the conduit to ensure its retention.
