Auxiliary Switches (GGC Model Only)
The GGC models include two integral auxiliary
switches with a switch adjuster accessible on either
face of the actuator (as illustrated in Figure 2 and
Figure 3). The nominal factory setting for Auxiliary
Switch No. 1 is 11° closing, and the nominal factory
setting for Auxiliary Switch No. 2 is 81° opening
(relative to a 0 to 90° rotation range). See the Technical
Specifications table for the auxiliary switch ratings.

Specifications table for the auxiliary switch ratings.
The switch point of Auxiliary Switch No. 1 is fixed. The
switch point of Auxiliary Switch No. 2 is independently
and continuously adjustable from 25 to 95°. See
Figure 16 and use the method in the following example
for the most accurate positioning of Auxiliary Switch
No. 2.

Repairs and Replacement
A number of replacement parts are available; see
Table 1 for more details. If the M9220-GGx-3
Proportional Electric Spring Return Actuator fails to
operate within its specifications, replace the unit. For a
replacement electric actuator, contact the nearest
Johnson Controls® representative.

WARNING: Risk of Electric Shock.
Disconnect each of multiple power
supplies before making electrical
connections. More than one disconnect
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.
