The M100C Series Motor Actuator is used in damper and valve
applications where proportional control from a digital controller is
required.
The M100C has the capability of communicating with Metasys
AHU/UNT or DSC1000 controllers depending on the position of the 8-pin
DIP switch. Other functions that are user programmable include master or
slave configuration, direct or reverse acting mode, the address to which the
actuator will respond and the linear or S-curve response characteristic.

M100C Actuators receive and interpret digital commands from a
controller for accurate positioning of the output shaft. The M100CAA-2 is
a dual direct and reverse action model replacing the M100CAA-1 (direct
acting only) and M100DAA-1 (reverse acting only) models.
The M100C Motor Actuator travel is factory set at 90 degrees and is field
adjustable from 65 to 270 degrees.
The timing of the actuator is 38 seconds for 90 degree rotation and
60 seconds for 160 degree rotation.

Figure 2: Direction of Rotation
All reference to the direction of rotation is when viewing the load end as
stamped on the actuator housing shown in Figure 2. From this view, the
Counterclockwise (CCW) limit is the zero reference.
The actuators are factory set at zero position which is 10 degree Clockwise
(CW) from vertical (see Figure 2) and for 90 degree clockwise travel.
When using Y20 linkage kits, each 15 degrees of actuator rotation results
in 0.1 inch (2.54 mm) of linear movement of the rack assembly.

Installation Procedures
•screwdriver, Phillips-head (No. 1 or 2)
•screwdriver, flat-blade, 1/8 inch tip
Note: All series M100 motor actuators are for use only as operating controls.
Where an operating control failure would result in personal injury
and/or loss of property, it is the responsibility of the user to add
devices (safety, limit controls) or systems (alarm, supervisory systems)
that protect against and/or warn of control failure.
•Follow NEC and local electrical codes.
•Disconnect all power supplies.
•Observe the following ranges and limitations:
Power Requirements 24 VAC at 50/60 Hz, 25 VA spring return, 20 VA non-spring return
Ambient Operating
Conditions -40° to 125°F (-40° to 52°C), 90% RH non-spring return
-35° to 125°F (-37° to 52°C), 90% RH spring return
Ambient Storage
Conditions -40° to 125°F (-40° to 52°C), 90% RH
•Do not install the motor actuator in atmospheres with explosive vapors
or escaping gases, or where vapors having deteriorating properties
might attack the actuator’s metal parts.
•Wiring into return air systems should be sealed to prevent aspiration of
corrosive air into the actuator.
Upright mounting of the motor actuator is required.
When mounting on a valve, do not mount below the horizontal plane of
the valve piping to prevent damage to the motor actuator if the valve leaks
or develops condensation.
Valve medium temperatures above 250°F (121°C) are permissible only if
the maximum ambient temperature at the motor actuator is less than
105°F (41°C).
Locate the motor actuator where the shaft and wiring terminals are accessible.
Follow installation procedures for the linkage kit used to couple the motor
actuator and the controlled device.
When not utilizing a damper or valve linkage kit, use four 1/4 x 1 inch
bolts for mounting the motor actuator.
Perform travel adjustments described in the Travel Adjustment section as required.

6 M Motor Actuators—M100C Series of Motor Actuators
To install the R81 board kit in a Series M100X base motor actuator or
remove and/or replace the electronic circuit boards in an existing Series
M100 motor actuator, proceed as follows:
!
CAUTION: Disconnect the electrical power supply before
attempting to remove the wiring connections and the
boards to prevent possible electrical shock or damage
to the equipment.
1. Remove the motor actuator’s top cover by loosening the two cover
screws.
2. Verify that power is removed from the unit and disconnect all wiring
connections to the terminal board.
3. Loosen the bracket screw and remove the bracket.
4. Pull the vertical board straight upward. Be careful not to bend or
damage the pin terminals.
5. Remove the two screws from the terminal board.
6. Remove the terminal board by grasping the receptacles and lifting
straight upward being careful not to bend or damage the pin terminals.
1. Install terminal board by carefully placing the terminal receptacles onto
the pin terminals.

5. Install the adhesive backed label supplied in the R81 kit.
IMPORTANT:As shown in Figure 7, locate the label on the insulation
barrier. The letter on the R81 label will complete the
number that identifies the Series M100 with the R81
installed.
6. Configure the switch settings as required by installation specifications
and shown in the Calibration Procedures section.
7. Install the motor actuator if it is not already mounted.
8. Make control and 24 VAC wiring connections as shown in the Control
Wiring section.
9. Turn on power supply.
10. Cycle the motor actuator using the Y199 tester or controller to check
operation.

!
CAUTION: Disconnect the electrical power supply before wiring
the motor actuator to avoid possible electrical shock
or damage to the equipment. Always disconnect the
24 VAC power supply before attempting to make any
wiring connections.
Make all wiring connections using copper conductors only. Wire in
accordance with National Electric Code and local regulations.

Wiring
Compartment
Figure 8: Wiring Junction Box Attached to M100
Make all splices in junction boxes using approved solderless connectors,
or by soldering and then taping the connections. Locate all splicing and
excess wiring outside the motor actuator wiring compartment. If desired,
add a standard electrical box to the wiring compartment of the motor
actuator as shown in Figure 8.
Runs less than 50 feet (15 m) long require no shielded cable. Avoid
running low voltage control wiring in the same conduit pipe as line voltage
wiring or other conductors that supply highly inductive loads (contactors,
coils, motors, generators, etc.).
If the control wiring is over 50 feet (15 m) long, run in a common conduit,
or near inductive loads, the use of shielded cable is recommended. Use 22
AWG gauge, Beldfoil 8761 or equivalent for runs up to 250 feet (76 m).
For 250 feet (76 m) to 500 feet (152 m) runs, use 18 AWG gauge Beldfoil
8760 or equivalent.
