Figure 1: M100 Motor Actuator
The design of the M100M is to provide direct interface with the followingHoneywell Controllers:
1. All Series 90 135 ohm slidewire controllers.
2. W973 and W7100 Series Controllers for modulating valves in heating,cooling and water source economizer applications.
In addition, W973 and W7100 Series Controllers can be accommodated inair-to-air economizer damper applications when using a diode (1N4002)and resistor (620 ohm, 1/2 watt).
Note: The M100M is not a direct replacement for air side economizerswith minimum position and outside air changeover logic asHoneywell wiring diagrams indicate. Refer to the wiring sectionfor logic connections.
The following table lists the torque rating for each model(MXXXMYZ—where X = Model No.):

The M100M horizontal terminal board is divided into two sections,Series 90 and W7100/W973.
The labeling of the Series 90 section contains Honeywell terminaldesignations R, B, and W. The wiring for a Series 90 Controller is colorfor color in heating applications and reversing W and B in coolingapplications.
For heating applications, as the wiper arm R on the Series 90 Controllermoves toward terminal B, the motor drives clockwise as viewed from theload end. As the wiper arm moves towards terminal W, the motor drivescounterclockwise. All Series 90 overrides and minimum positionnetworks are applicable.
The labeling of the W7100/W973 section is with terminal designationsR1/T1 and W1. The labels of the W973 terminals are RH and WH forheating, RC and WC for cooling, and R and W for economizerapplications. The labels of the W7100 terminals are R and W for heating,cooling and economizer applications. Terminals R1/T1 and W1 respondto the control signal generated by the W973/W7100.
Note: The M100M must be the master motor actuator. It is not to be aslave.

4 M Motor Actuators—M100M Proportional Motor Actuator
The M100M can slave up to ten M100J slave actuators. Each slaveactuator must have a separate transformer. Do not mix Johnson Controlsand Honeywell actuators in a master/slave application. All slave actuatorsmust be of the same manufacturer as the master actuator.
The voltage between terminals T and X (when jumpered from XD or XR)is approximately 6 VDC at zero rotation of the output shaft. Full rotationof the output shaft occurs when the voltage between T1 and X isapproximately 10 VDC.
The M100M Motor Actuator travel is factory set at 90 degrees and isadjustable from 65 to 270 degrees.
The timing of the actuator is 38 seconds for 90 degree rotation and60 seconds for 160 degree rotation.

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

Installation Procedures
screwdriver, Phillips-head (No. 1 or 2 tip)
screwdriver, flat-blade, 1/8 inch tip
Note: All Series M100 Motor Actuators are for use only as operatingcontrols. Where an operating control failure would result in personalinjury and/or loss of property, it is the responsibility of the user to adddevices (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 OperatingConditions
-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 StorageConditions
-40° to 125°F (-40° to 52°C), 90% RH
• Do not install the motor actuator in atmospheres with explosive vaporsor escaping gases, or where vapors having deteriorating propertiesmight attack the actuator’s metal parts.
• Wiring into return air systems should be sealed to prevent aspiration ofcorrosive air into the actuator.
Upright mounting of the motor actuator is required.
When mounting on a valve, do not mount below the horizontal plane ofthe valve piping to prevent damage to the motor actuator if the valve leaksor develops condensation.
Valve medium temperatures above 250°F (121°C) are permissible only ifthe 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 motoractuator and the controlled device.

Mounting
M Motor Actuators—M100M Proportional Motor Actuator 7
When not utilizing a damper or valve linkage kit, use four 1/4 x 1 inchbolts for mounting the motor actuator.
Perform travel adjustments as described in the Travel Adjustment section.
To install the R81 interface kit in a Series M100X Base Motor Actuator orremove and/or replace the electronic circuit boards in an existing SeriesM100 Motor Actuator, proceed as follows:

9. Adjust, and check operation.
! CAUTION: Disconnect the electrical power supply before wiringthe motor actuator to avoid possible electrical shockor damage to the equipment. Always disconnect the24 VAC power supply before attempting to make anywiring connections.
Control Wiring
10 M Motor Actuators—M100M Proportional Motor Actuator
Make all wiring connections using copper conductors only. Wire inaccordance with National Electric Code and local regulations.
M100F04
WiringCompartment
Figure 8: Attaching Wiring Junction Box To M100
Make all splices in junction boxes using approved solderless connectors,or by soldering and then taping the connections. Locate all splicing andexcess wiring outside the motor actuator wiring compartment. If desired,add a standard electrical box to the wiring compartment of the motoractuator as shown in Figure 8.
Runs less than 50 feet (15 m) long require no shielded cable for theVDC/mA control wiring. Avoid running low voltage control wiring in thesame conduit as line voltage wiring or other conductors that supply highlyinductive 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, we recommend the use of shielded cable. Use 22AWG 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 Beldfoil8760 or equivalent. Connect the shield only at the controller. Do notconnect shield to any other point.

3. Install the conduit connector to the motor actuator and secure using theconduit nut provided with the connector.
4. Connect the controller to the terminals located in the wiringcompartment.
5. Connect 24 VAC to terminals T1 and T2.
Note: To avoid potential miswiring or control signal problems, the use ofseparate transformers on each M100 is required.

Calibration Procedures
The travel adjustment potentiometer mounted on the R81M horizontalterminal board enables positioning the M100 Actuator from 65 to270 degrees rotation. Changing the travel adjustment affects the clockwiselimit. Turn the adjustment clockwise to increase travel andcounterclockwise to reduce total travel.
To make adjustments, use the following procedure or refer to theappropriate valve or damper linkage instruction.
1. Set the travel adjustment potentiometer fully counterclockwise.
2. Remove all control wires.
! CAUTION: Disconnect the electrical power supply beforeattempting to remove the wiring connections and theboards to prevent possible electrical shock or damageto the equipment.
3. Apply 24 VAC between R1/T1 and T2.
4. Jumper terminals R and B to drive the motor to the fully clockwiseposition as viewed from the load end.
5. Slowly rotate the travel adjustment potentiometer clockwise toincrease motor rotation until the corresponding valve or damper is inthe desired position.
6. Remove the jumper between terminals R and B, enabling the motor toreturn to the full counterclockwise position as viewed from the loadend.
7. Repeat steps four through six to provide proper stroking.
8. Turn off the 24 VAC and remove the 24 VAC from terminals R1/T1and T2. Connect all control wires.
