Safety Considerations As with any electro-mechanical device, safety should be considered during installation and operation of your Type 330SA electric actuator. Throughout this manual you will see Warnings and Cautions. These are intended to provide you with helpful information to ensure a safe and trouble free installation.
Installation WARNING Type 330SA electric actuators have third party certification for hazardous areas. Opening or tampering with the housing will void the certification.
3
Type 330SA Mounting Configurations Two mounting configurations are available, front face mounting and rear clevis mount.
CAUTION Misalignment can cause extremely high side loads on the actuator rod which can cause premature wear of the actuator mechanism. For those applications where the actuator is held rigidly (i.e. front face mounting) the end of the rod must be held within 0.127 mm (0.005 inches) from the center of the actuator or be free floating with side load not exceeding J 90 N (20 lb) for size 20, J 133 N (30 lb) for size 30, J 222 N (50 lb) for size 45, or J 350 N (75 lb) for size 60 actuators.
CAUTION For longest possible life, limit side loading of the rod to less than 90 N (20 lb) for size 20, 156 N (35 lb) for size 30, 222 N (50 lb) for size 45, or 350 N (75 lb) for size 60 actuators. An appropriately designed external anti-rotate mechanism may be used to carry higher side loads.

WARNING Avoid personal injury or damage to the actuator or surrounding equipment. Properly tighten the hex nuts or cap screws to the torque values given in table 5.
Rear Clevis Mount
CAUTION Caution must be taken when using this mounting configuration to ensure that play in the system does not allow the actuator to go out of alignment. This mounting configuration is intended to be a direct replacement for hydraulic cylinders and therefore sizes for the clevises have been selected in customary US units, as shown in table 6. Table 6. Clevis Pin Sizes ACTUATOR SIZE
Front Face Mounting Front face mounting is used to attach the actuator to an existing surface. This is accomplished either by using extended tie rods, or by using hex head or socket head cap screws which fit into pre-drilled and tapped holes in the front face of the actuator. In either case, the thread size used is the same. For extended tie rod mounting, remove the four hex nuts from the front end of the actuator. Pass the extended tie rods through pre-drilled holes in the existing surface. Replace the four nuts and torque to the values listed in table 5. When using cap screws, place the front face of the actuator against the pre-existing surface, aligning the tapped holes with the through-holes in the existing surface. Insert the cap screws and torque to the values listed in table 5.

Cable Routing When Supplied with MS Style Connector Over time, liquid contaminants such as oil and cleaning solutions may run down the cables and into the connectors. To minimize this situation, route the cables so there is a loop in the cable just before the connector. Generally the preferred orientation is to have the cables coming out the side of the actuator or downward whenever possible. If it becomes necessary to attach the actuator with the cable connectors on the top, loop the cable at least 360_ just before the connector. This will provide a trap for the contaminants. See figure 3.
Type 330SA WARNING DO NOT attempt to operate the actuator with the brake applied. Allowing the actuator to operate with the brake applied may cause serious damage to the actuator and/or the brake. Do not use the brake to support heavy loads while an operator is under the load. Provide another means of support to lock the load in position. The brake is a spring applied friction device and does not provide a positive lock mechanism.
E0042-IL
Figure 3. Cable Routing
Internal Brake When Supplied as an Option
The holding brake is not intended to stop the actuator motion or movement, but is intended to hold the actuator in position in case of a power loss situation.
Note The internal brake option is only available with non-explosion proof actuator construction. Some applications require the addition of the internal holding brake. The brake is held open by the supply of power to a magnetic/mechanical clutch. Whenever power to the brake is lost or is “switched off�, the armature is locked in place. This prevents the inverted roller screw from back driving which, in turn, stops the output rod from moving. The addition of the brake lengthens the actuator and reduces the total travel (see table 7). All other dimensions remain the same as those shown in table 4. Table 7.

Anti-Rotate Systems You must provide some type of anti-rotate mechanism to prevent the rod from rotating. The anti-rotate mechanism can be inherent to the application or it can be provided by some external means. The anti-rotate mechanism must withstand the motor stall torque (see table 1). If the actuator was supplied by Fisher Controls mounted to a valve, the anti-rotate requirements have already been met.

This section describes how to connect your Type 330SA linear actuator to its servo drive. The following is an overview of the types of connections required. Refer to figures 8 and 11 for schematics. Additional detailed wiring information is provided in the following section titled Wiring Connections.
WARNING Avoid personal injury or equipment damage resulting from contact with high voltages and currents which may be present in the electronic servo drive and servo actuator. Do not disconnect the wiring from any of the devices while the devices are powered.
Actuator Power Cable You may purchase the actuator power cable from Fisher Controls. If you choose another source, please note the following cable requirements. D Cable length must not exceed 76 meters (250 feet). D The minimum requirements for this cable are four 14 AWG wires to carry the power and two 20 AWG wires (preferably twisted pair) for the temperature sensor. D Power to the motor is controlled by pulse width modulation, which makes the power cable a source for radiated electrical noise (EMI). Shielding the cable will reduce EMI emissions. A typical installation will have the cable in metal conduit. More than one power cable can be in the same conduit. Do not put the resolver feedback cable, or any other EMI sensitive cable, in the same conduit as a power cable.

Resolver Feedback Cable
Brake Cable
The interconnecting cable length must be 76 meters (250 feet) or less. This cable can be purchased from Fisher Controls or you may provide your own. The resolver feedback cable is connected to low current, high impedance circuits, making it susceptible to radiated electrical noise (EMI). The minimum requirements for this cable is that it contain three twisted pairs of 24 AWG wire, with a shield around the wires. Larger diameter wire is better, but if it is too large it will be difficult to wire the connector. A better cable will have each of the twisted pairs shielded, as well as the whole cable.
The interconnecting cable length must be 76 meters (250 feet) or less. This cable can be purchased from Fisher Controls or you may provide your own. The brake cable is not susceptible to radiated electrical noise (EMI), nor is it a significant generator of EMI. The minimum requirements for this cable is that it contain two 24 AWG wires. Larger diameter wire is better, especially if the cable is longer than 30.5 meters (100 feet).
A typical installation will have the cable in metal conduit. More than one resolver cable can be in the same
A typical installation will have the cable in metal conduit. More than one brake cable can be in the same conduit. It is permissible to put the brake cable the same conduit as a power cable. Figure 7 shows the connections for this cable. See also tables 9 and 10.

Type 330SA Wiring Connections The Type 330SA actuator has a variety of available cable sets that can be used with either the FX-Series servo drive or the VC1000 servo drive.
For the actuator motor end of the cable
1. Connect the red, black, blue, and green wire to the same colored wires coming out of the actuator motor.
FX-Series Servo Drive
WARNING To avoid personal injury from shock hazard, do not touch R, S, and T and power terminals until you are assured that electrical potential has dissipated. Under a fault condition, the R, S, and T terminals can hold voltages at dangerous levels. Check these terminals with a voltmeter to ensure voltage is not present after power down. If voltage is present, bleed off before handling.
2. Connect the light blue wire to one of the white wires coming from the actuator motor. 3. Connect the light blue/white wire to the other white wire coming from the actuator motor.
Resolver Feedback Cable
For the FX-Series drive end of the cable
Refer to the Fisher Controls FX-Series instruction manual or contact your sales office for other installation concerns, such as transformer sizing and fuse capacities.
1. Connect the resolver connector to the resolver input connector on the end of the drive.
Power Source Cable (220 VAC or 460 VAC)
2. Connect the 2-pin Molex connector to the mating connector on the power cable.
1. Connect the 220 VAC source to the bridge power L1, L2, and either of the ground terminals on the drive. If 3-phase power is being used, connect the third phase to L3. 2. Connect a jumper wire from the bridge power L1 terminal to the logic power L1 terminal. 3. Connect a jumper wire from the bridge power L2 terminal to the logic power L2 terminal. Actuator Power Cable For the FX-Series drive end of the cable 1. Connect the red, black, and blue wires of the actuator power cable to the R, S, and T terminals on the drive. 2. Connect the green wire to either of the ground terminals. 3. Connect the light blue and light blue with white wires to the appropriate location to detect motor overheating condition. (The device inside the motor is a thermally activated switch.)
10
For the actuator motor end of the cable
1. Connect each wire in the resolver cable to the same colored wire coming from the actuator motor. 2. Connect the bare (no insulation) shield wires together. Normally these are not connected to any electrical ground point at the actuator motor.
Analog Control Signal Input
To use a 4 to 20 milliamp input control signal, connect a 500 ohm, 1/2 watt resistor between the 0 to +10 VDC terminal and the ground terminal.

Figure 9. Resolver Feedback Cable Connector
Alternate Wiring Connections FX-Series Servo Drive Power Source (DC Power) The servo drive can also be operated using 325 to 350 VDC instead of 220 VAC. Wire power as follows: 1. Connect the 325-350 VDC positive source to the bridge power L1. 2. Connect the 325-350 VDC negative source to the bridge power L2. 3. Connect the 325-350 VDC ground to either of the ground terminals on the drive. 4. Connect a jumper wire from the bridge power L1 terminal to the logic power L1 terminal. 5. Connect a jumper wire from the bridge power L2 terminal to the logic power L2 terminal. Resolver Feedback Cable The FX-Series drive end of the cable requires a special connector. The connector is a 9-pin male “D” connector (see figure 9).
The actuator thermal switch located inside the actuator motor housing is normally closed. If the motor temperature exceeds the thermal switch setting, the switch opens and the FX-Series drive immediately disconnects the output power to the actuator. For some critical applications, it is desirable to bypass the automatic power disconnect and to disconnect the power by some other means. To bypass the automatic power disconnect, pins 5 and 9 in the resolver feedback cable connector must be connected to each other. The actuator thermal switch must then be sensed by some other device which will permit an orderly shutdown of the process and disconnect power to protect the actuator from overheating. The wiring of this connector is shown in table 12. Table 12. Resolver Feedback Connector Wiring PIN 1

WARNING
Power Source Cable (220 VAC) 1. Connect the 220 VAC source to the power terminals L1, L2, and either of the ground terminals on the drive.
To avoid personal injury from shock hazard, do not touch R, S, and T and power terminals until you are assured that electrical potential has dissipated.
Actuator Power Cable
Under a fault condition, the R, S, and T terminals can hold voltages at dangerous levels. Check these terminals with a voltmeter to ensure voltage is not present after power down. If voltage is present, bleed off before handling.
1. Connect the red, black, and blue wires of the actuator power cable to the R, S, and T terminals on the drive.
Refer to the Fisher Controls VC1000 instruction manual or contact your sales office for other installation concerns, such as transformer sizing and fuse capacities.
For the VC1000-Series drive end of the cable
2. Connect the green wire to either of the ground terminals. 3. Connect the light blue and light blue with white wires to MOT TH+ and MOT TH– to detect motor overheating condition. (The device inside the motor is a thermally activated switch.)
13
Type 330SA For the actuator motor end of the cable 1. Connect the red, black, blue, and green wire to the same colored wires coming out of the actuator motor. 2. Connect the light blue wire to one of the white wires coming from the actuator motor. 3. Connect the light blue/white wire to the other white wire coming from the actuator motor.

Resolver Feedback Cable For the VC1000-Series drive end of the cable 1. Connect the resolver connector to the resolver input connector on the drive. For the actuator motor end of the cable
Resolver Feedback Cable The VC1000-Series drive end of the cable requires a special connector. The connector is a 9-pin female “D” connector (see figure 9).
1. Connect each wire in the resolver cable to the same colored wire coming from the actuator motor. 2. The bare (no insulation) shield wire normally is not connected to any electrical ground point at the actuator motor. Analog Control Signal Input The 4 to 20 milliamp input control signal is connected to the COMMAND+ and COMMAND– pins on the 15 pin input connector. Position Feedback Signal The valve position can be monitored through a 4-20 mA output signal from the drive. Connections are made at the POSITION+ and POSITION– pins on the 12-pin Output connector.
Alternate Wiring Connections VC1000 Series Power Source (DC Power) The servo drive can also be operated using 125 VDC instead of 220 VAC. Note the 125 VDC unit is a different model than the 220 VAC unit. Wire power as follows: 1. Connect the 125 VDC positive source to the bridge power L1/DC+ terminal. 2. Connect the 125 VDC negative source to the bridge power L2/DC– terminal. 3. Connect the ground to either of the ground terminals on the drive.
14
Note The actuator thermal switch located inside the actuator motor housing is normally closed. If the motor temperature exceeds the thermal switch setting, the switch opens and the VC1000-Series drive immediately disconnects the output power to the actuator. For some critical applications, it is desirable to bypass the automatic power disconnect and to disconnect the power by some other means. To bypass the automatic power disconnect, pins 5 and 9 in the resolver feedback cable connector must be connected to each other. The actuator thermal switch must then be sensed by some other device which will permit an orderly shutdown of the process and disconnect power to protect the actuator from overheating.

Type 330SA Table 14. Troubleshooting Chart Symptom/Trouble
Possible Cause/Troubleshooting Procedure
Actuator does not respond
1. Check cable connections. 2. Check Drive/Controller.
Actuator is unstable (erratic motion)
1. Drive may not be properly tuned. Refer to your drive manual for tuning. 2. Resolver cable is shorted or damaged. Flex cable at both ends to check for intermittent operation. 3. Resolver cable is not wired properly. See resolver wiring diagram in figure 4 and tables 9 and 10. 4. Motor power wiring in wrong order (R.S.T.)
Actuator is unable to move load
1. Load is too large. 2. Excessive side loading. For longest possible life, limit side loading to the maximum rod side load (table 1). 3. Check alignment of rod with applied load. 4. Power amplifier too small.
Housing moves or vibrates when shaft is in motion Shaft rotates
1. Check actuator mounting. Ensure that the actuator is securely mounted. See Mounting Configurations on page 4. 2. Improper gain settings (refer to drive manual) 1. Install an anti-rotate system. See page 5.
Brake does not hold load in place
1. See WARNING on page 5. 2. This type of holding brake must not be used to stop the actuator and load unless a power loss situation occurs.
Actuator is over heating (the surface of the actuator has exceeded 80_C [176_F])
1. Insufficient lubrication. 2. Actuator is being operated outside the continuous operating zone. 3. Check gain settings. Refer to your drive manual for tuning.
or tampering with the housing will void the certification. Contact your sales office to coordinate repair of your Type 330SA actuator.
Maintenance WARNING Type 330SA electric actuators have third party certification for hazardous areas. Opening or tampering with the housing will void the certification. Type 330SA actuators are not field serviceable. They are third party certified for hazardous areas. Opening
