Limit Controller E5CN-FR 1
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.
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.
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.
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.

■Alarm Types
Select alarm types out of the 12 alarm types listed in the following table.
Note: 1. With set values 1, 4 and 5, the upper and lower limit values
can be set independently for each alarm type, and are
expressed as “L” and “H.”
2. Set value: 1, Upper- and lower-limit alarm
3. Set value: 4, Upper- and lower-limit range
4. Set value: 5, Upper- and lower-limit with standby sequence
For Upper- and Lower-Limit Alarm Described Above
•Case 1 and 2
Always OFF when the upper-limit and lower-limit
hysteresis overlaps.
•Case 3: Always OFF
5. Set value: 5, Upper- and lower-limit with standby sequence
Always OFF when the upper-limit and lower-limit hysteresis
overlaps.
6. The annunciator output turns ON to inform users when a
limit over occurs. This function is enabled by selecting 12
(annunciator output) for alarm 1 type. The annunciator
output turns ON when a limit over occurs, and turns OFF for
the RESET operation.
Set the alarm types for alarms 1 and 2 independently in the initial
setting level. The default setting is 12 (annunciator) for alarm 1 type
and 2 (upper limit) for alarm 2 type.

External Connections
•Standard insulation is applied between any of the following: power supply terminals, input terminals, output terminals, and communications
terminals (for models with communications). If reinforced insulation is required, provide additional insulation, such as spacial distance or
material insulation, as defined by IEC 60664 suitable for the maximum operating voltage.
•Consult with your OMRON representative before using the external power supply for the ES1B for any other purpose.

Operating Method
■Outline of Operation Procedures
The following diagram illustrates the entire setting level. A password is required to enter the advance function setting level and the calibration level.
Some parameters may not be displayed depending on the protection settings and operation conditions.
The control operation will stop when switching from operation level to initial setting level.
Note: 1. Operation level entered for software reset.
2. You cannot move to other levels by operating the keys on the front panel from the calibration level. You must turn OFF the power supply.
3. The time taken to move to the protect level can be adjusted by changing the “Move to protect level time” setting.
Troubleshooting
When an error has occurred, the No. 1 display shows the error code. Take necessary measure according to the error code, referring the table
bellow.
Note: 1. Refer to “E5CN-FR Limit Controller User’s Manual” for details of the control range.
2. These errors are displayed only when the PV/Limit SP is displayed.
3. If the display is restored to normal after cycling the power supply, the error may have been caused by noise. Check for noise being generated nearby.
