Preface

OMRON products are manufactured for use according to proper procedures by a qualified operator

and only for the purposes described in this manual.

The E5CN, E5CN-U, E5AN, and E5EN are Digital Temperature Controllers. The E5CN and E5CN-U

are both compact temperature controllers, with the E5CN featuring screw terminal connections, and

the E5CN-U featuring socket pin connections. The main functions and characteristics of these Digital

Temperature Controllers are as follows:

• Any of the following types of input can be used: thermocouple, platinum

resistance thermometer, infrared sensor, analog voltage, or analog cur-

rent.

• Either standard or heating/cooling control can be performed.

• Both auto-tuning and self-tuning are supported.

• Event inputs can be used to switch set points (multi-SP function), switch

between RUN and STOP status, switch between automatic and manual

operation, and start/reset the simple program function. (Event input are

not applicable to the E5CN-U.)

• Heater burnout detection and HS alarms are supported. (Applicable to

E5CN, E5AN, and E5EN models with heater burnout detection function.)

• Communications are supported. (Applicable to E5CN, E5AN, and E5EN

models with communications.)

• User calibration of the sensor input is supported.

• The structure is waterproof (NEMA 4X indoor use, equivalent to IP66).

(Not applicable to the E5CN-U.)

• Conforms to UL, CSA, and IEC safety standards and EMC Directive.

• The PV display color can be switched to make process status easy to

understand at a glance.

This manual describes the E5CN, E5CN-U, E5AN, and E5EN. Read this manual thoroughly and be

sure you understand it before attempting to use the Digital Temperature Controller and use the Digital

Temperature Controller correctly according to the information provided. Keep this manual in a safe

place for easy reference. Refer to the following manual for further information on communications:
