Chapter 1: Hardware Overview Chapter 1: Hardware Overview The Series 955QD Brik with Quadrature Output is an accurate, auto-tuning, non-contact, linear displacement transducer in an economical, low prole package. The transducer utilizes our eld proven magnetostrictive technology to give absolute position, repeatable to .01% of the programmable sensing distance. The streamlined anodized aluminum extrusion houses the sensing element and electronics. -

Chapter 2: Installing the LDT Chapter 2: Installing the LDT Mounting Instructions The Series 955QD can be mounted vertically or horizontally using SD0522000 mounting brackets. The mounting brackets slide in the grooves on the lower part of the extrusion and clamp down when tightened. It is recommended to use one mounting bracket on each end and every three feet in between. -

Chapter 3: 955QD Overview Chapter 3: 955QD Overview 3.1: Quadrature Output A new method of interfacing magnetostrictive transducers offers customers an interface as common as analog with the speed and accuracy of pulsed type signaling. The Gemco 955QD LDT provides quadrature output directly from the transducer to the controller (see drawing below). - Page 8 Chapter 3: 955QD Overview The TTL level threshold signals are activated when these inputs exceed the typical TTL level threshold, which is 2.0VDC. Additionally, for the 24VDC level signals, the customer can specify either a “sourcing” or “sinking” type of input.

Page 9: Quadrature Output Resolution And Speed
Chapter 3: 955QD Overview 3.3: Quadrature Output Resolution and Speed The internal resolution of the 955QD Gemco LDT is 0.001”. This would be represented to the encoder input device by specifying an output resolution of 1,000 cycles per inch for the transducer. Although the typical resolution is 1,000 cycles per inch (CPI), the transducer can be ordered with virtually any CPI setting. - Page 10 Chapter 3: 955QD Overview CONNECTOR PLUG - EXPLODED VIEW P/N: SD0527700 10 PIN CONNECTOR (AS VIEWED AT SOLDER SIDE 4X SIZE CABLE CONN.

Chapter 3: 955QD Overview 3.5: Features Automatic Gain Control The Automatic Gain Control feature is only used when sensing a magnet other than the standard SD0521800 slide magnet. If you are using the standard slide magnet, skip this operation. When using the Floating Magnet assembly (SD0522100), the magnet should be installed within 3/8” of the sensing surface. - Page 15 Chapter 3: 955QD Overview Burst Mode This feature enables the system to be absolute even though data transfer is through “incremental” method. In the event of power failure, the controller can be programmed to automatically send a signal to the probe, which will then respond with the current position data.
- Page 16 Chapter 3: 955QD Overview 3.6: 955QD Frequency or Pulse Rate Selecting the proper frequency in the LDT’s part number is very important. The internal clock inside of the 955QD interrogates the LDT approximately every 1 millisecond on LDT’s less than 60” in length and approximately every 2 milliseconds on the units greater than 60”...

Page 17: Troubleshooting For 955Qd
Chapter 3: 955QD Overview 3.7: Troubleshooting for 955QD Troubleshooting describes common problems that may occur when installing the LDT and offers possible solutions to these problems. If, after reading this appendix, you are unable to resolve a problem, contact our technical support department at 248-435-0700. - Page 18 Chapter 3: 955QD Overview If reading is between 10 and 30 VDC, turn power supply off and go to step 7. If reading is below 10 VDC, either your power supply is not providing enough power or the LDT’s cable possibly has a short/open.
