Omron E5CN-FR Manual

Limit Controller
E5CN-FR
This Best-selling General-purpose 48×48-mm
Temperature Controller Is Now Even Better
with the Addition of Limit Controller Models
Delivering Complete Functionality for Limit
Outputs and Easy Settings with 11-segment
Display.
• Connect to either of three options with the same model:
Infrared temperature sensor, thermocouple, or platinum resis-
tance thermometer.
• Reset limit outputs using event inputs (models that support event
inputs).
• Communications functions are now provided for Modbus (RTU)
or CompoWay/F communications protocols (models with
communications functions).
• Water-resistant construction (NEMA4X for indoor use, equiva-
lent to IP66).
• Conforms to FM (Factory Mutual) standards (FM3545/3810).
• Conforms to international standards including UL, CSA, and IEC
safety standards and EMC.
• Easily see the status from a distance with PV display with
two-color switching function.
• On-board power supply option is available for ES1B Infrared
Thermosensor.
Note: Refer to Precautions on page 14.
Features
Complete Limit Controller Functionality
Trace Error Status
Check the maximum temperature during an error and the time
lapsed since the error occurred using the "limit over continuation
time" and "limit over max./min. value" measuring functions.
New Annunciator Output Warning Function
Hazard lights and buzzers on the devices alert the user of errors
when limit over errors occur.
Basic Performance and Functionality as Easy as Temperature Controllers
Make Settings Easily with 11-segment Displays
The E5CN-FR uses an 11-segment display, the same as the E5CN.
The alphabet is clearly displayed, eliminating the need to make
parameter settings while having to decipher symbols, which was an
inconvenience of previous general-purpose temperature controllers.
Multiple Inputs with a Single Controller
A single Controller supports both thermocouple and platinum-
resistance thermometer inputs, eliminating the need to select models
depending on the input. This contributes toward reducing the number
of service parts required as well as decreasing inventory levels.
Reset Limit Outputs Using Event Inputs (Models
with Event Inputs)
Limit outputs can be reset using event inputs, enabling multiple limit
outputs to be reset altogether from a distance.
Input Error Output Function
Alarm signals are output if a sensor disconnection or other input
error occurs, enabling application in equipment and facilities
requiring safety design.
Easily Check Error Status Using the
Two-color Switching Display
The PV display switches colors to enable status to be easily checked
from a distance.
