Notes:

1) Conditions which have not been specified are to be taken as: 24V DC supply voltage,

+20˚C

ambient temperature, SELECT gain setting, 300ms response time setting, center measuring distance, interference prevention function not used, and white ceramic board object.

2) For details of the applicable sensor head, please refer to the instruction manual of the sensor head.

3) Including the sensor head.

4) Take care that when the gain is set to AUTO, the linearity and the resolution may deteriorate.

5) For LH-CD6(P), this is the response time for CH 1 or CH 2 setting. The response time for Calculation setting is four times this value. Also, take care that when the response time is set to AUTO, the linearity, resolution and the response time will vary.

6) This is the value for white ceramic board object. The linearity may differ depending on the measured object. Further, in case of LH-CD6(P), this is the value for CH 1 or CH 2 setting. For calculation setting, the linearity is approx. twice the value given in the above table.

7) The linearity of the sensor head and the controller has been adjusted at the time of shipment. Carry out the shift adjustment and the span adjustment to suit the operating conditions.

8) Take care that the linearity, resolution and the response time may deteriorate when the interference prevention function is used.

x CAUTIONS

This controller has been designed to meet the specifications when used along with the optional exclusive sensor heads. In case it is used in a combination that does not use the optional exclusive sensor heads, not onl y the specifications ma y not be met, b ut it ma y also cause an accident, etc. Hence, always use this controller along with the exc lusive sensor heads.

䢇 Use this product 30 min. after the power is supplied. Immediately on supply of power,

the electrical circuit is yet to stabilize, which may cause variation in measured values.

䢇 Take care that after switching on the power supply, there is a muting time of 5 sec. 䢇

Make sure to carry out the wiring in the power supply off condition.

䢇 Take care that wrong wiring will damage the sensor. 䢇 Verify that the supply voltage variation is within the rating. 䢇 If power is supplied from a commercial switching regulator,

ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.

䢇

In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F .G.) terminal of the equipment to an actual ground.

䢇 Do not r un the wires together with high-voltage lines or power lines or put them in

the same raceway. This can cause malfunction due to induction.

䢇 The analog output and the alarm output are not incorporated with a short-circuit pro-

tection circuit. Do not connect them directly to a power supply or a capacitive load.

䢇 Avoid dust, dirt, and steam. 䢇 Take care that the sensor does not come in direct contact with water, oil, grease, or

organic solvents, such as, thinner, etc.

䢇 Mount the controller such that the ventilation holes are not blocked. 䢇 If the controller is used for a long time, although it becomes hot, this does not indi-

cate any abnormality. However, if the controller is used by being enclosed in a control box, make sure to provide for enough heat radiation or cooling by fan, etc.

c MOUNTING

Controller mounting frame (ATA4811) (Accessory)

q Insert the controller, from its rear portion, into

the cut-out of the panel.

w Insert the enclosed controller mounting frame

(ATA4811) from the rear side of the controller and push it till the end.

e Tighten the controller mounting frame uniformly ,

using the mounting screws (2 Nos.) enclosed with it. After mounting on the panel, make sure to confirm that the controller is firmly mounted

and that it does not shake.

Note: If the mounting screws are tightened excessiv ely, the control-

ler mounting frame gets displaced. In case this happens, loosen the screws once, push in the controller mounting frame and then tighten the mounting screws.

v CONNECTION

䢇 Connection of sensor head to controller

Make sure to connect or disconnect the connector to the controller in the power supply off condition.

• One sensor head can be connected to LH-CS6(P), whereas, up to two sensor heads can be connected to LH-CD6(P). Hold the sensor head’s connector and insert it into the connector provided on the controller for sensor head connection. Insert till it locks.

Connector

Connector for sensor head

※ To remove the sensor head, hold its connector by the outer ring and pull it straight

out. While removing the connector from the controller, take care not to touch the terminals inside the connector. (Do not pull by holding the cable, as this can result in cable disconnection.)

Note: Not used in LH-CS6.

Notes:

1) The device connected to ‘q Analog voltage output’ should have an input impedance of 1MΩ or more.

2) The device connected to ‘e Analog current output’ should have a load resistance of 300Ω or less.

3) In case of LH-CS6, terminal No. y is not used.

4) Do not wire an interference prevention I/O other than that of LH-CS6(P) or LH-CD6(P) to the interference prevention I/O. Further, do not connect together two controllers which have both been set as masters during interference prevention setting, as this will cause a fault.
