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 exclusive sensor heads, not only the specifications may not be met, but it may also cause an accident, etc. Hence, always use this controller along with the exclusive sensor heads.

ӟ Make sure to carry out the wiring in the power supply off condition. ӟ Take care that wrong wiring will damage the sensor. ӟ Verify that the supply voltage variation is within the rating. ӟ Use this product 10 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.

ӟ Take care that after switching on the power supply, there is a

muting time of 5 sec.

ӟ 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.

ӟ 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.

ӟ Do not run the wires together with high-

voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.

ӟ The controller cable can be extended up to total 50m with a

0.22mm

, or more, cable. However, use a 0.15mm2shield wire for

the analog output cable extension.

ӟ The analog output and the alarm output are not incorporated with a

short-circuit protection circuit. Do not connect them directly to a power supply or a capacitive load.

ӟ Avoid dust, dirt, and steam. ӟ Take care that the sensor does not come in direct contact with

water, oil, grease, or organic solvents, such as, thinner, etc.

ӟ If the controller is used for a long time, although it becomes hot, this

does not indicate any abnormality. However, if the controller is used by being enclosed in a control box, make sure that heat is not trapped inside by providing for heat radiation or cooling by fan, etc.

ӟ The operation panel may get hot. However, this does not indicate

any abnormality.

ӟ This sensor is suitable for indoor use only.

c MOUNTING

How to mount the controller

Ο Fit the rear part of the mounting

section on the attached controller mounting bracket (

MS-DIN-3

35mm width DIN rail.

Π Pushing the controller forward,

press down the front part of the mounting section on the controller mounting bracket (

MS-DIN-3

the DIN rail to fit it.

How to remove the controller

Ο Push the controller forward.

Lift up the front part of the controller

to remove it.

Note: Take care that if the front part is lifted

without pushing the controller forwards, the hooks on the rear portion of the mounting section are likely to break.

Ұ 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.
