Expert - The Simple Way to Configure and Control
Expert, the Tritex II user interface software, provides you with a simple way to select all aspects of configuration and control required to set up and operate a Tritex II actuator. Easy to use tabbed pages provide access to input all of the parameters necessary to successfully configure your motion application. "Application" files give you a convenient way to store and redistribute configurations amongst multiple computers, and "Drive" files allow the same configuration to be distributed to multiple Tritex II actuators. Motion setup, homing, teach mode, tuning parameters, jogging, I/O configuration, and local control are all accomplished with ease using Expert software.

Motion Setup
Within the Expert software, Exlar provides several system configurations for various applications. These can serve as your configuration, or as a starting point for your configuration. Alternatively, you can begin from scratch selecting configuration details specific to your application. You can configure a move to position, move to switch, or move to force motion at the click of a button. The Tritex II products offer absolute and incremental motion, as well as moves ending on a condition such as a specific force or torque being reached, or an input being triggered by a proximity switch. |

Control Page
The Expert control page gives you the ability to operate or initiate all motion functions form one single, simple screen. This screen provides you very easy system start-up and testing without all the inconvenience of machine wiring.
The control page offers the capability to enable and disable the drive and perform fast and slow jogs. This gives you the ability to verify motion before needing any I/O wiring. |
 |
Monitor Page
All input functions can be monitored and activated from the Expert monitor page, and all output functions can be monitored. These functions can be monitored and controlled, even if they are not programmed as the function of any particular hardware input or output. Information on critical fault and status data is available as a separate page, or as a fixed window on the bottom of each page of the software. |
Configuring I/O
Configuring I/O points to one of over 40 available input or output functions couldn't be easier. A pull-down menu adjacent to each I/O point allows all I/O to be set up in minutes.
Inputs can be configured to be maintained, or momentary, depending on the application requirements.
Input and output logic can also be inverted with a simple click. |
 |
Homing
The Tritex II homing setup is simple to use. It allows you to home to an input, by using a proximity or limit switch, or allows homing to a specific force or torque.
Homing to a force or torque is ideal for setting up applications that require motion referenced to a hard stop, like the closed position of a valve, or the final position of a press. |
 |
Teach Mode
To provide the easiest motion set up possible, Tritex II products offer "Teach Mode". In this mode, you can jog the actuator to the desired position, and activate an input, or click a button in the Expert software and the current position of the actuator becomes the defined distance or absolute position associated with a particular move command. |

Process Control Functionality
Tritex II actuators, available in both rotary and linear versions, provide a perfect solution for your valve actuation needs. Small hysteresis and dead band, quick response to small signal changes and stable dynamic responses delivered by Tritex II actuators are all key parameters for process control.
Fully programmable to follow an analog signal representing either position or force, the Tritex II linear actuator is perfectly designed for sliding stem valve applications with thrust requirements up to 368 lbs. Highly accurate position feedback allows the Tritex II to achieve combined repeatability and hysteresis as low as 0.25%.
The Tritex II rotary actuators are ideal for operating quarter-turn, ful-turn, or multi-turn valves or shaft driven dampers. In shaft driven applications, the rotary Tritex II actuators are directly coupled shaft-to-shaft. This eliminates the ungainly mechanisms usually necessary to convert the linear motion of pneumatic and hydraulic cylinders to rotational motion. Gear ratios of 4:1 to 100:1 allow the power of Tritex II to be applied to a broad range of applications.
Tritex II actuators can be mounted on any valve form any manufacturer.
Benefits for Process Control Applications
100% Torque Availability
Full torque means almost zero deadband, and stiction in the valve stem is no problem. Current is always available so it will hold its position. This provides excellent process loop control.
Speed of Response
Tritex II response rate is measured in milliseconds. This provides excellent modulating control of both ball valves and butterfly valves.
High Accuracy
Tritex II actuators have a built-in position feedback sensor, providing much higher accuracy over potentiometer-based actuators.
Custom Valve Seat
Exlar linear actuators stroke the valve based on position, but can switch to torque mode when seating the valve. This allows a tight cut-off. It also helps with retrofitting valves that may have some wear. For new valves it makes sure damage isn't done due to over-forcing the stroke.
High Stiffness
Similar to hydraulic actuators, but without the cost or maintenance issues, Tritex II actuators are extremely stiff. This allows control down to the smallest operating range (<1%) and also eliminates dynamic flow problems such as negative gradients.
Fast Stroke Speeds
Most other electric actuators are known for being slow - a major disadvantage. Tritex actuators can close a valve in milliseconds if needed.
Improved Control
Under modulating conditions, Tritex II actuators provide precise closed loop tracking by effectively eliminating non-linearities and deadtime.
Valve Software
Our valve software is simple to use, featuring a teach mode for foolproof configuration. Included is a programmable valve cut off position feature that enables a firm valve seat on both new valves, or retrofitted valves.
