Operating Instructions Temperature Indicating Controller CF2S

Thank you for your purchase of our Microcomputer based Temperature Indicating Controller CF2S. This manual contains instructions for the mounting, functions, operations and notes when operating the CF2S. For model confirmation and unit specifications, please read this instruction manual carefully before starting operation.

To prevent accidents arising from the use of this controller, please ensure the operator using it receives this manual.

***** Note to users ***** Before operating this controller, make sure you have understood the following.

Warning

Turn the power supply to the instrument OFF before wiring or checking. Working or touching the terminal with the power switched ON may result in an Electric Shock which could cause severe injury or death. Moreover, the instrument must be grounded before the power supply to the instrument is turned on.

Caution

• Do not apply a commercial power source to the sensor connected to the input terminal nor allow the power source to come into contact with the sensor, as the input circuit may be burnt out.

• This instrument should be used according to the specifications described in the manual. If it is used outside the specifications, it may malfunction or cause fire.

• Be sure to follow the warnings, cautions and notices. If not, it could cause serious injury or malfunction.

• Specifications of the CF2S and the contents of this instruction manual are subject to change without notice.

• Care has been taken to assure that the contents of this instruction manual are correct, but if there are any doubts, mistakes or questions, please inform our sales department.

• Be sure to turn the power supplied to the instrunment OFF when cleaning.

• Wipe the instrument using dry soft cloth.

(If the paint thinner is used for wiping, the instrument may be deformed or discolored.)

• The display parts are more easily damaged. Do not strike them with hard objects

or press hard on them.

• Any unauthorized transfer or copying of this document, in part or in whole, is prohibited.

• WIKA is not responsible for any damages or secondary damages incurred as a result of using this product, including any indirect damages.

• Setup by the DIP switch and the rotary switch inside of the controller is required before the power is turned on.

• It is recommended that the PID auto-tuning be performed on the trial run.

• It is advised to provide the protective device against such environmental conditions which may cause damage to the device or contribute to the deterioration of its parts.

3.1 Taking the internal assembly out

Warning

Do not take the inner assembly out nor touch the terminal with the power supply on. Touching the terminal with the power switched ON may result in an Electric Shock which could cause severe injury or death.

Before the power supply to this instrument is on, take the internal assembly out from the case by pushing the hook (bottom of the instrument) in the direction indicated by the arrow and holding the notches.
