LK-G-M-F-E.fm 2 ページ 2006年5月11日 木曜日 午前11時16分 WARRANTIES AND DISCLAIMERS Introduction This Instruction Manual describes the basic operations and hardware functions of the LK-G Series. Read this manual carefully to ensure the optimum performance and full function of the LK-G Series before use. Keep this manual in a safe place for future reference. Be sure that the person who will finally operate this product receives this manual.
Safety Precautions General Cautions • At startup and during operation, be sure to monitor the functions and performance of the LK-G Series. • We recommend that you take substantial safety measures to avoid any damage in the event of a problem occurring. • Do not attempt to open or modify the LK-G Series or use it in any way other than as described in the specifications. If the LK-G Series is modified or used other than as described, the warranty will be voided.
CAUTION Follow the safety precautions below to ensure safe operation • Be sure to turn the power off when you plug/unplug the cable that leads to the unit and its accessories. Not following this caution may result in damage. • Do not turn off the power while setting items. The data being set or all the data may be lost. • Do not block the vent holes on the unit. Increase of internal temperature may cause failure.
Influence of dust or dirt The measurement may fluctuate due to dirt, dust or fluid such as water or oil in the following cases: • Adhesion on the protection glass: Blow the dirt off with clean air. If dirt persists, wipe the glass surface gently using a soft cloth moistened with alcohol. • Adhesion on the surface of the measuring target: Blow the dirt off with clean air or wipe it off.
EMI: EN61326, class A EMS: EN61326 Length of the power cord that is connected to the Controller, and length of all input/output cords must be limited to shorter than 30 m. Precautions for Wiring Part of the circuits between the inputs and output are internal common. Make sure that a potential difference does not occur between internal common terminals due to a potential difference between wires or external devices. Otherwise, it may cause malfunctions in the unit or external devices.

Target shape The installation of the head in the orientations indicated by the circle in the figures below is recommended.
1 Before Use Installing the Controller Install the controller to the DIN rail, or fix it with screws. 1 Caution on the orientation of the LK-G Series Install the controller in the orientations shown in the following figures with a circle. Do not install it upside down. Be sure to leave 30 mm of clearance or more above the controller, and 10 mm or more on each side. In addition, for ensuring the safe connection of the cord, leave 65 mm space or more in front of the terminal panel of the controller.
1 Before Use Installing the LK-G3001V/LK-G3001PVLK-G3001PV (single unit type controller) Install it on its bottom.
1 Before Use Separating the single unit type controller 1 Disconnect the display panel cable from the display panel connector on the controller’s terminal panel. 1 Remove the display panel cable from the guide on the bottom of the controller. 2 Loosen the display panel fixing screw. Reference The display panel fixing screw does not drop from the display panel fixing case. 3 Remove the display panel fixing case from the controller.

Slide the front panel in the direction of the arrow. 1 CAUTION Be sure to check the orientation of the claws on the connector side before installation. Otherwise, the claws break and cause malfunction. 5 6 Fix the display panel fixing case by tightening the display panel fixing screw. Route the display panel cable along the guide, and connect it to the display panel connector on the rear of the controller.
1 Before Use Connection CAUTION 1 • Be sure to turn off the power of the controller before connecting/disconnecting cables. Failure to do so may cause malfunction. • Ensure that the orientation of the connector is correct. Otherwise the pin could break and may lead to system malfunction. • Part of each input/output circuit of the LK-G Series is internally common.
1 Before Use ■ Connecting the display panel In the case of the separate type controller, the display panel cable is used for connecting the controller to the display panel. Reference The LK-G series can be operated without the display panel. In addition, the operation from a PC is possible by using the "LK-Navigator" software. ■ Connecting the power Connect the 24V DC power to the terminals 1 and 2 of the 12-pin terminal block.

Operations and Functions during Measurement 2 This chapter describes the operations that can be performed during displacement measurement and their functions. 2 Switching the Measurement Value Displays..........................2-2 Setting the Tolerance Comparator Values .............................2-3 Setting the Display Value Instantaneously to Zero (Auto-Zero)....................................................................2-6 Program Function .......................................................
2 Operations and Functions during Measurement Switching the Measurement Value Displays This section describes how to switch the measurement value display contents. 2 During measurement, the following three types of display can be switched. Press the to switch displays.
2 Operations and Functions during Measurement Setting the Tolerance Comparator Value This section describes how to read the tolerance comparator display, and its setting procedure. 2 The Function of the Tolerance Settings HIGH and LOW comparator tolerance values can be set. The measured value can be displayed and output in 3 steps: when exceeding the HI comparator value (HI), when the value drops below the LOW comparator value (LOW), and when the value is between the HI and LOW comparator values (GO).
2 Operations and Functions during Measurement Note Measurement stops while the setting is in progress. ■ Setting Procedures for tolerance comparator values. 1 2 2 3 4 Press the key. Enters the tolerance setting mode. For changing the OUT No. to be set, press the Press the key, and set the value with the key. HI GO LO TIM OUT2 HI GO LO TIM keys. OUT1 HI GO LO TIM As an example, the tolerance on the HI side of OUT1 is set to 4.0000. OUT2 HI GO LO TIM Press the keys.
2 Operations and Functions during Measurement Hysteresis If the measurement value is fluctuating around the tolerance comparator value, the comparator output may repeatedly turn on and off. By setting a hysteresis, a gap may be generated between the detected value and the return value of the tolerance comparator, thus avoiding this phenomenon. When the comparator output format is normal, the comparator output is as follows. Hysteresis is not set by default when shipped from the factory.
2 Operations and Functions during Measurement Setting the Display Value Instantaneously to Zero (Auto-Zero) 2 This section describes the auto-zero function, which is used for referencing zero-point position. Operation of the key or others resets the present displayed value to "0.0000". By considering this zero position as a reference, the increase and decrease are displayed in ± (positive/negative). This function can be used for reference zero-point positioning when a workpiece is changed.
