Figure 1: M100

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.

Mounting

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.

MMotor Actuators—M100C Series of Motor Actuators 9

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.
