(Refer to p.916) Common functions (common to general purpose controller and high-functional controller) Item Function Outline Automatically sets the gain to the optimum level to match changes in the reflection AUTO gain setting function ratio for the measured objects. Lets the user select the gain to match changes in the reflection ratio for the Measuring condition SELECT gain setting function measured objects. Lets the user select the response time to match the line speed for the measured Response time setting function objects. Analog output Adjusts the analog output and the Shift adjustment function shift value for display values. Analog output Adjusts the analog output and the Span adjustment function span value for display values. Adjustment Measurement value Forcibly resets the currently Display value measured value to ‘0’ and then 0-ADJ function caries out measurement with this ‘0’ value as a reference 0-ADJ input 0-ADJ function clear function Returns the value which was forcibly set to ‘0’ using the 0-ADJ function back to its original value. 0-ADJ value memory function Enables the 0-ADJ value to be stored in memory. Analog output off-set function Applies a user-defined offset to the analog output. Teaching function Allow the measured value for the measured object to be used to set the threshold value. Time chart Sensing Sensing condition Non-sensing ON-delay: ON Disables short-term detection. Comparative output Normal operation OFF Timer function OFF-delay: ON T Extends the output signal for a constant ON-delay OFF ON length of time. T TT OFF-delay OFF Timer period: T�0 to 1,000 ms Distance display / Displacement value display select function Toggles the display between distance and displacement value display. Display Sleep function Turns off value display. If measurement is not possible, this function maintains analog output at the level Analog output hold function output immediately before this occurs. Others Prevents mutual interference when using two sensors in close proximity. Interference prevention function [If using the LH-CD6(P) high-functional controller, interference can be prevented for up to four sensors.] Additional functions (high-functional controller) Item Function Outline Automatically sets the response time to match the line speed of the measured Measuring condition Automatic response time setting function objects in order to provide optimum resolution. Carries out arithmetical processing on the channel A input value and the channel B input value. A�B: Calculates the sum of the measured values for channel A and channel B. A�B: Calculates the difference between the measured values for channel A and channel B. Calculation function L�(A�B): Subtracts the sum of the measured values for channel A and channel B from a constant value L. [LH-CD6(P) only] L�(A�B): Subtracts the measured value for channel B from the measured value for channel A, and subtracts the result from a constant value L. Calculation and measurement (A�B) / 2 : Obtains the simple average of the measured values for channel A and channel B. Peak-to-peak hold: Holds and displays the difference between the maximum and minimum values obtained during the measuring period. Measurement function Peak hold: Holds and displays the maximum value obtained during the measuring period. Bottom hold: Holds and displays the minimum value obtained during the measuring period. Set value memory Set value memory function Allows setting details to be stored in up to 16 different memory locations. Allows measured values and setting values to be transmitted via an RS-232C interface.

Frequently asked questions

What makes Elite.Parts unique?

At GID Industrial (Elite.Parts' parent company), we specialize in procuring industrial parts. We know where to find the rare and obsolete equipment that our customers need in order to get back to business. There are other companies who claim to do what we do, but we're confident that our commitment to quality and value is unparalleled in our field.

What kind of warranty will the LH-54 have?

Warranties differ by part and by which suppliers we use to procure it for you. Sometimes, a part will be sold as-is and without a warranty. Our specialty, single board computers, tend to receive a one-year warranty.

Which carriers does Elite.Parts work with?

Elite.Parts can ship via FedEx, UPS, DHL, and USPS. We have accounts with each of them and generally ship using one of those, but we can also ship using your account if you would prefer. However, we can use other carriers if it will be more convenient for you.

Will Elite.Parts sell to me even though I live outside the USA?

Absolutely! We are happy to serve customers regardless of location. We work with international clients all the time, and we are familiar with shipping to destinations all across the globe.

HARD TO FIND A BETTER PROVIDER

Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.

Applied Materials

CONSISTENTLY DELIVERS QUALITY SOLUTIONS

Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE

This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

Trican Well Service

GO TO SOURCE

When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
