SUPPLY POWER
TERMINALS 1, 2, AND 3
Standard supply power for the model 22-309
is single-phase 120 VAC (refer to the actuator
nameplate for specific rating). Input power
connects line to terminal 1, neutral to terminal 2,
and ground to the enclosure power ground screw.
Terminal 3 is unused for 120 VAC operation.
Standard supply power for the model 22-409 is
three-phase 208 VAC. Lines 1, 2, and 3 connect
to terminals 1, 2, and 3 respectively on this
actuator. The ground wire should be connected to
the enclosure power ground screw.
Alternate voltage options include single-phase
240 VAC for the model 22-309 and three-phase
208, 240, 380, 416, 480, & 575 VAC for both
Group 22 models. The Group 22 requires an
optional transformer enclosure to accommodate
any non-standard voltage configuration.
Group 22 actuators are equipped with a
transient protector assembly installed across
each, or a combination of terminals 1, 2, and
3 (dependent upon your actuator model and
configuration). Note: The transient protector
assembly should not be removed.
AUXILIARY LIMIT SWITCHES
TERMINALS 4 THROUGH 9
Group 22 actuators include two single pole
double throw (SPDT) auxiliary limit switches rated
for 1 Amp at 250 VAC. These switches may be
useful for discrete position indication. The limit
switches are actuated by adjustable cams on the
control shaft (located with the position sensing
device). Details on standard factory switch
settings can be found in the configuration section
of this manual.
AUTO MODE INDICATION
TERMINALS 10 AND 11
A dry contact is available at terminals 10 and
11 to indicate when the Handswitch is in the AUTO
position. The switch contact is Form A; when
the Handswitch is not in the AUTO position, the
contact is open and when the Handswitch is in the
AUTO position, the contact is closed. The contact
is rated for 1 Amp at 250 VAC.
CAUTION
Always close covers immediately
after installation or service to prevent
moisture or other foreign matter
from entering the actuator.
SYSTEM ALARM
TERMINALS 12 AND 13
Indication of the system alarm is available as
a dry contact at terminals 12 and 13. The factory
standard is to open on alarm, but it may be
reconfigured to close on alarm. Note that when
power is lost, the contact opens. Reference the
configuration section of the manual for additional
details on how to change this functionality. The
contact is rated for a maximum of 80 milliamps at
120 VAC/VDC.
DEMAND SIGNAL
TERMINALS 14 AND 15
The DCM monitors an analog 4-20 milliamp
input signal at terminals 14 (–) and 15 (+), and
positions the output shaft position to match in
response. The standard response is to follow the
Demand signal linearly.
FEEDBACK SIGNAL
TERMINALS 16 AND 17
The DCM-2 transmits a 4-20 milliamp position
feedback signal on terminals 22 (–) and 24 (+)
that is proportional to the actuator output shaft
position.
CONTROL
OVERRIDE INPUTS
TERMINALS 18 THROUGH 21
Analog signal operation may be overridden by
using discrete input signals on the control override
input terminals. CW (19), CCW (20), and STOP
(21) terminals require connection to a common
(COM) terminal (18) to perform the override as
shown in the table below.

Stop in Current Position
The connection to terminal 18 is designed to
be made through relay contacts or through a solid
state switch capable of sinking at least 5 milliamps
DC. When the circuit is open, terminals 19, 20,
and 21 should m12 VDC with respect to
terminal 18.
CAUTION
Do not connect an external voltage
source to override terminals 18–21;
an external voltage source may
damage the DCM circuitry.
