Section 1
General Information
1.1 General
This manual provides instructions for the installation, operation, and maintenance of the Duff-Norton SPA with Intelli-
Motion Actuator. It includes proper procedures for the disassembly, cleaning, inspection, rebuilding and assembly of the
actuator. To ensure efficient, long, satisfactory use of this unit, follow these instructions closely.
1.2 Applications
The actuators described and illustrated in this manual are intended for industrial use only and should not be used to lift,
support or otherwise transport people (unless you have a written statement from Duff-Norton Company that authorizes
this actuator unit, as used in your application, as suitable for moving people).
1.3 Factory Preparation
Each actuator is carefully assembled and tested at the factory to ensure that the motor and the mechanical components
will function properly, and that the actuator will lift its rated load.
The brake is preset at the factory and no further adjustment is required. With proper maintenance, this brake prevents the
actuator from self-lowering. The actuator is pre-lubricated at the factory and thus requires minimum maintenance.
Limit switches are checked at the factory for proper functioning.
1.4 Warranty
Subject to the conditions stated herein, Duff-Norton will repair or replace, without charge, any parts proven to Duff-
Norton’s satisfaction to have been defective in material or workmanship. Claims must be made within one year after date
of shipment. Duff-Norton will not repair or replace any parts that become inoperative because of improper maintenance,
eccentric loading, overloading, chemical or abrasive action, excessive heat, or other abuse.
Equipment and accessories not of Duff-Norton’s manufacture are warranted only to the extent that they are warranted by
the manufacturer, and only if the claimed defect arose during normal use, applications and service.
Equipment which has been altered or modified by anyone without Duff-Norton’s authorization is not warranted by Duff-
Norton. EXCEPT AS STATED HEREIN, DUFF-NORTON MAKES NO OTHER WARRANTIES, EXPRESS OR IMPLIED,
INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
If you have any questions concerning warranty repair, please contact Duff-Norton Customer Service. Authorization for

Installation
2.1 Installation Procedures
2.1.1 Mechanical Installation
Duff-Norton electromechanical actuators can be used in tension, compression or combination tension/compression
applications. Examples of tension and compression appear on the right.
Mount the actuator to avoid side loading and eccentric loading. To optimize the performance and life of the actuator,
mount it so that the load is applied along the longitudinal axis of the translating tube. Examples of proper and improper
loading arrangements appear below.
Proper Loading
Improper Loading
Side Loading Eccentric Loading

SPA Actuator with Intelli-Motion™ Technology Manual R00

Page 9 of 48
Once the optimal mounting arrangement has been determined, mount Duff-Norton electromechanical actuators by
slipping a solid pin through the translating tube clevis and rear housing clevis. The pins must be parallel to each other to
avoid binding. The actuator restraining brackets and related hardware must be able to withstand the torque generated by
the actuator as it extends and retracts. Restraining torque varies with actuator family.

2.3 Analog I/O Adjustments
Figure 2-6: Selector Switches
Configure the Analog Input and Output using the selector switches on the User I/O board (behind the access cover on the
actuator). Select the input or output to be V (0 - 10V DC) or mA (4 - 20 mA). The input may be configured differently from the
output if preferred.
The Analog Output indicates the position of the actuator, scaled to the factory limits.
In “analog position” mode, the Analog Input may be used to select a target, or “Go-To” position for the actuator. To enable
this function, move the selector switch by “AIN” from “DIS” to “ENABLE.” When this function is enabled, the actuator will
attempt to move to the position selected by the Analog Input whenever the Enable digital input is asserted (+24V). (In this
mode, the Extend and Retract digital inputs are NOT used.) Table 2-3 on page 16 shows the scaling for both the Analog
Input and the Analog Output.

SPA Actuator with Intelli-Motion™ Technology Manual R00
May 2022
Page 16 of 48
Table 2-3: Analog Mode Scaling
2.4 Limit Switch Adjustment
• The Extend Limit and Retract Limit are preset at the factory to prevent overtravel of the actuator.
• Travel limits may be set inside of these boundaries according to the application needs. To set the limits from the
User I/O board, simply operate the actuator to the preferred position for the Retract Limit, and press the R-Limit
button. The R-Limit LED will blink once to acknowledge the setup. Then operate the actuator to the preferred position
for the Extend Limit, and press the E-Limit button. The E-Limit LED will blink once to acknowledge the setup.
• To erase a user-settable limit, press and hold the corresponding button (R-Limit or E-Limit) for over
2 seconds. The limit will be erased, and the corresponding LED will blink 3 times to acknowledge the operation. The
factory limits will still be in place.
• The limits may also be configured using the Intelli-Motion Configurator software.
2.5 Setting the Actuator Speed
For the base and analog models, the default actuator speed is 100% (0.83 in./sec). The speed may be adjusted for
application requirements using the Intelli-Motion Configurator software.
For the Ethernet I/P model, the actuator speed may be set through the control messaging. See Section 4.2 on page 20 for
more details.
2.6 LED Indicators

3.2.2 Setup
The Setup tab allows the user to observe and configure the speed and limit settings for a base or analog model. This tab
is view-only for Ethernet models (see Section 4.2 on page 20).
The top slider bar allows the user to change the operational speed of the actuator, or the user may enter the desired
speed into the text box. Clicking the arrow buttons will also incrementally move the indicator left or right along the slider.
Clicking “Reset Default Speed” will reset the speed to the default.
The bottom slider bar allows the user to change the Retract and Extend limits for the actuator. Text boxes are also
provided to manually set the limit values. Clicking the arrow buttons will incrementally move the indicator left or right
along the slider. Clicking “Reset Default Limits” will reset the limits to the default.
Once the desired settings are selected, click the “Send to Actuator” button to send the updated values to the actuator.
If the user desires to see the units displayed in millimeters rather than inches, select Units -> Millimeters.
3.2.3 Feedback
The Feedback tab shows the current status of the dip switches, as well as the state of any Analog Inputs and Outputs.
If using an EthernetIP model, the status bits (StatusBits in the User-Defined Data Type [UDT]) and their definitions will
display on this page as well. The StatusBits include feedback on the state of the device as well as the I/O message that
the actuator is receiving.
3.2.4 Maintenance
The Maintenance tab shows various status and operational values from the actuator. This tab includes faults, event log

4.2 Models with Ethernet I/P Control Interface
4.2.1 Connecting Your SPA with Intelli-Motion
The SPA with Intelli-Motion utilizes a static IP address for EthernetIP connections. The static IP address can be
configured with the Configurator. Following the connection instructions in Section 4.2.1 on page 20, connect the SPA with
Intelli-Motion to the Configurator. After connecting, an Ethernet tab will appear in the Configurator for Ethernet models
(iSPAXXXX-X-XX-E or -ES). Set the appropriate IP address and subnet mask for your application. IP addresses and subnet
masks that are incompatible with the intended host will prevent the SPA with Intelli-Motion from appearing on the
network. An example setup, to be used with a PLC having an IP address of 169.254.181.15, appears in the image below.
Click the “Send to Actuator” button to save the new network parameters.
Note that the gateway address can be left at 0.0.0.0 for most applications and that THE UNIT MUST BE REBOOTED FOR
THE NEW NETWORK PARAMETERS TO TAKE EFFECT.
After power-cycling the unit, use the appropriate cable to connect the SPA with Intelli-Motion to a computer or controller.
