Applications

The M9220-GGx-3 Proportional Electric Actuators are direct-mount, spring return electric ac tu ators that operate on AC/DC 24V power. These bidirectional actuators do not require a damper linkage, and are easily installed on dampers with 1/2 to 3/4 in. or 12 to 19 mm round shafts, or 3/8 and 1/2 in. or 10, 12, and 14 mm square shafts using the standard shaft clamp included with the actuator. An optional M9220-600 Jackshaft Coupler Kit is available for 3/4 to 1-1/16 in. or 19 to 27 mm round shafts, or 5/8 and 3/4 in. or 16, 18, and 19 mm square shafts.

A single M9220-GGx-3 Series Proportional Electric Spring Return Actuator provides a running and sprin g return torque of 177 lb·in (20 N·m). Two or three like models mounted in tandem deliver twice or triple the torque (354 lb·in [40 N·m] or 531 lb·in [60 N·m]). Integral line voltage auxiliary switches are available on the GGC models to indicate end-stop position or to perform switching functions within the selected rotatio n range.

IMPORTANT: Use this M9220-GGx-3 Proportional Electric Spring Return Actuator only to control equipment under normal operating conditions. Where failure or malfunction of the electric actuator could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the electric actuator.

IMPORTANT : Utiliser ce M9220-GGx-3 Proportional Electric Spring Return Actuator uniquement pour commander des équipements dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du electric actuator risque de provoquer des blessures ou d'endommager l'équipement contrôlé ou un autre équipement, la conception du système de contrô le doit intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que des systèmes de supervision ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement du electric actuator.

proceed as follows:

1. Mount the coupler on either Side A or Side B of the actuator, as determined by the shaft length.

2. Snap the locking clip securely into the coupler retention groove to retain the coupler.

Manual Override

Use only the supplied manual override crank to reposition the actuator hub when using the manual override feature.

IMPORTANT: Applying excessive torque to the manual override or running the manual override with a power tool may damage the internal components of the actuator and cause premature failure.

To reposition the actuator hub, proceed as follows:

1. De-energize the actuator.

2. Insert the hex end of the manual override crank into the manual override adjustment point on the face of the actuator.

3. Rotate the manual override crank in the direction indicated by the arrow on the label.

Note: The actuator requires 27 rotations of the manual override crank from the fully spring return position to fully reposition the actuator hub. At the end of travel, the rotational resistance increases; do not force the actuator hub past this point.

4. Rotate the manual override crank a half turn in the opposite direction to lock the actuator hub in place.

Note: To unlock the actuator hub, rotate the manual override crank in the direction indicated by the arrow on the label. The actuator hub automatically unlocks when power is applied to the actuator, and returns the actuator to normal drive and spring return operation.

Mounting the Actuator

To mount the actuator, proceed as follows:

1. See the dimensions in Figure 5 and Table 2 to ensure the correct positioning of the anti-rotation bracket.

6. Rotate the damper blades to the desired position i f the power is lost. To ensure a tight seal, insert the manual override crank and turn it in the direction indicated by the arrow on the label five turns; the position indicator should be near the 0° position on the scale. Quickly rotate the manual override crank a half turn in the opposite direction to temporarily lock the actuator hub in place.

7. Evenly hand tighten each clamp nut onto the U-bolt, keeping the actuator flat. Secure the U-bolt to the damper shaft and tighten to a torque of 100 to 125 lb·in (11 to 14 N·m).

8. To release the spring, turn the manual override crank in the direction indicated on the label; the actuator spring returns to its starting position. If th is step is omitted, the spring releases automatically when power is applied to the actuator.

9. Remove the manual override crank and store it in an unused mounting hole.

10. Apply power long enough for the actuator to travel a full stroke, and verify that the actuator rotates freely throughout the range.

Note: If electric power is not available, complete this verification by reinserting the manual override crank and turning it in the direction indicated to rotate the coupler to the fully open position.

3. Drill mounting holes in the damper frame or duct using the anti-rotation bracket as a guide (based on the measurements obtained in Table 2 and Figure 5).

4. Secure the anti-rotation bracket to the damper frame or duct using the two M3 x 9.5 mm self-drilling sheet metal screws provided and a 1/4 in. (6 mm) blade screwdriver or 5/16 in. (8 mm) nut driver .

IMPORTANT: Do not overtighten the mounting screws to avoid stripping the threads. Be certain that the tab on the anti-rotation bracket re mains prop erly positioned in the slot on the actuator, and that the actuator remains parallel to the mounting surface.

5. Slide the actuator onto the damper shaft, and position the tab of the anti-rotation bracket into the slot at the bottom of the actuator as illustrated in Figure 6.

Rotation Range Using Optional M9220-603 Adjustable Stop Kit

The actuator is factory set for 90° rotation, and its rotation range is limited in 5° increments to a minimum of 30°. Stroke limiting stops are attached in the field to the shaft coupler side of the actuator to reduce the rotation range. Attaching a stroke limiting stop in the furthest mounting position reduces the rotation r ange of the actuator by 5°. Each progressive mounting position reduces the rotation range an additional 5°.

1. Check that the damper blade is accessible or that its position is permanently marked on the end of the damper shaft as illustrated in Figure 7.

:dampos

2. Determine the desired rotation range. If a 65 to 90° rotation range is desired, add one stroke limiting stop. If a 35 to 60° rotation range is desired, add two stroke limiting stops.

Wiring

The M9220-GGx-3 Proportional Electric Spring Return Actuator provides reliable, integrated damper control. An AC 24 V at 50/60 Hz or DC 24 V input signal between the black and red wires, and a DC 0(2) to 10 V input control signal, causes the output hub to rotate from -5 to 90° (unless an external mechanical limit is reached).

CAUTION: Risk of Property Damage.

Do not apply power to the system before checking all wiring connections. Short circuited or improperly connected wires may result in permanent damage to the equipment.

MISE EN GARDE : Risque de dégâts matériels.

Ne pas mettre le système sous tension avant d'avoir vérifié tous les raccords de câblage. Des fils formant un court-circuit ou connectés de façon incorrecte risquent d'endommager irrémédiablement l'équipement.

IMPORTANT: Make all wiring connections in accordance with local, national, and regional regulations. Do not exceed the electrical ratings of the M9220-GGx-3 Proportional Electric Spring Return Actuator.

Once the actuator reaches the commanded position, it holds that position until power is removed. If power is removed, the actuator spring returns to its

-5° position (unless an external mechanical limit is

reached). A stall condition while driving between

-5 to 90° causes the output hub to stop motion and

hold its position until power is removed. Rotation is mechanically limited to the -5 and 90° positions by

integral end-stops. Optional end-stops are available to limit the output hub travel. An anti-rotation bracket prevents rotational movement of the actuator body.

Direction of Action

The M9220-GGx-3 Proportional Electric Spring Return Actuators are factory set for Direct Acting (DA) operation. In DA mode, applying an increasing input signal to the control input drives the actuator away from the spring return position. Reverse Acting (RA) operation is also available. In RA mode, applying an increasing input signal to the control input drives the actuator toward the spring return position. Figure 12 and Figure 13 indicate how the drive direction for the actuator depends on the spring return direction a nd the position of the mode selection switch.

Mode Selector Switch and CAL Function

The M9220-GGx-3 Proportional Electric Spring Return Actuators are factory set at Direct Acting (DA), DC 0 to 10 V control input (Figure 13). To change to RA operation, move the mode selection switch from DA to RA. The DC input signal is selectable from DC 0 to 10 V or from DC 2 to 10 V, which corresponds to 0 to 90° rotation. If the rotation range is reduced , the end-stop is reached with a reduced input signal. For example, if a DC 0 to 10 V input signal is selected and the rotation range is limited to 75°, the end-stop is reached at DC 8.3 V. If an external 500 ohm resistor is placed across the input (see Figure 10), the switch positions then select between 0-20 mA or 4-20 mA.

0° is the spring return position.

Side A of Actuator Side B of Actuator

The CAL function enables the actuator to redefine the selected control input range proportionally across a reduced rotation range. The actuator stores the reduced rotation range in nonvolatile memory (retains data when power is lost or removed).

To calibrate the control input range, proceed as follows:

1. With power off, move the mode selection switch to the CAL position (Figure 13). Then, energize the

S O P V R D

: G

I F

actuator. The actuator automatically rotates until the end-stops are found, and proportionally reconfigures the control input range to the reduced rotation range.

2. Return the mode selection switch to the desired selection (example: DA, 0 to 10 VDC control input).

Note: During normal operation, if the actuator stroke increases due to seal or seat wear, the input is redefined to the increased rotation range in approximately 0.5° increments.

3. If the actuator mounting position is changed or if the linkage is adjusted, repeat Steps 1 and 2 to reinitiate the CAL function.

Note: To repeat calibration with power applied, move the mode selection switch out of the CAL position for at least 2 seconds before returning it to the CAL position. Auto calibration begins 5 seconds after you return it to the CAL position.

The tandem configuration (Figure 14 and Figure 16) provides twice (with two actuators) or triple (with three actuators) the running and spring retu rn torq u e of a single actuator, or 354 lb·in (40 N·m), 531 lb·in (60 N·m). The actuators may be mounted in tandem using the M9000-158 Tandem Mounting Kit. To mount a third actuator, user-configured bracketing is required.

DC 0(2)...10V Control with Tandem Connection

• Two or three M9220-GGx-3 actuators may be operated in tandem on the same shaft. If mounting two actuators, see Figure 14; for three actuators, see Figure 16.

• Each actuator requires separate 24 volt power. When two or more actuators connected in tandem share a common power source, the total maximum power draw is actually 1.5 times the normal running current for each actuator. (Total Power = Number of Actuators x Running Power x 1.5).

• The master and slave(s) must spring return in the

same direction.

• Once tandem-operating actuators are mounted to a damper shaft, manual override is no longer an available function.

The feedback wire of the master (orange) is connected to the command wire(s) of the slave(s)(gray). As the master moves response to position commands, the master sets its feedback wire to 0 volts if moving counterclockwise, 5 volts if holding, or 10 volts if moving clockwise.

Each slave actuator must have its tandem selector switch (Figure 15) set on the slave setting. Its gray command wire must be connected the master’s orange feedback wire.

Position information, 0-10 (or 2-10) volts, is available on the slave actuator’s feedback wire (orange).

Note: Electrical override still functions after the actuators configured for tandem operatio n are mounted to a damper shaft. The actuator has a 150-second drive time when operating in this mode.

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 fac tor y setting for Auxiliary Switch No. 2 is 81° opening (relative to a 0 to 90° rotation range). See the

Technical Specifications

ratings.

WARNING: Risk of Electric Shock. Disconnect or isolate all power supplies before making electrical connections. More than one disconnect or isolation 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.

AVERTISSEMENT : Risque de décharge électrique.
