For details onparticular functions and how to use them, refer to SECTION 3 Basic Operation and following sections.Input Sensor Types• The following input sensors can be connected for temperature input:Thermocouple:K, J, T, E, L, U, N, R, S, BInfrared temperature sensor:ES1B10 to 70°C, 60 to 120°C, 115 to 165°C,140 to 260°CPlatinum resistance thermometer:Pt100, JPt100Analog input:0 to 50 mV• Inputs with the following specifications can be connected for analog input.Current input: 4 to 20 mA DC, 0 to 20 mA DCVoltage input: 1 to 5 VDC, 0 to 5 V DC, 0 to 10 V DCControl Outputs• A control output can be relay, voltage, or current output, depending on themodel.• Long-life relay outputs use semiconductors for switching when closingand opening the circuit, thereby reducing chattering and arcing andimproving durability.
However, if high levels of noise or surge are imposedbetween the output terminals, short-circuit faults may occasionally occur.If the output becomes permanently shorted, there is the danger of fire dueto overheating of the heater. Design safety into the system, includingmeasures to prevent excessive temperature rise and spreading of fire.Take countermeasures such as installing a surge absorber.
As an additional safety measure, provide error detection in the control loop. (Use theLoop Break Alarm (LBA) and HS alarm that are provided for the E5@N.)VaristorLong-liferelay outputInductiveload1Varistor2Select a surge absorber that satisfies the following conditions.Voltage used100 to 120 VAC200 to 240 VACVaristor voltage240 to 270 V440 to 470 VSurge resistance1,000 A min.• Always connect an AC load to a long-life relay output. The output will notturn OFF if a DC load is connected.• With the E5CN-@2@@, alarm output 2 is used as control output (cooling)when heating/cooling control is selected. Therefore, use alarm 1 if analarm is required while using heating/cooling control.• With the E5AN/E5EN-@3@@, alarm output 3 is used as control output(cooling) when heating/cooling control is selected. Therefore, use alarms1 and 2 if an alarm is required while using heating/cooling control.Alarms• Alarms can be used with the E5CN-@2@@, E5CN-@1@@@U, or E5CN@2@@@U.
Set the alarm classification and alarm value or the alarm'supper and lower limits.• If necessary, a more comprehensive alarm function can be achieved bysetting the standby sequence, alarm hysteresis, close in alarm/open inalarm, and alarm latch parameters.8I/O Configuration and Main FunctionsSection 1-2• When the “input error output” parameter is set to ON, alarm output 1 turnsON when an input error occurs.Control Adjustment• Optimum PID constants can be set easily by performing AT (auto-tuning)or ST (self-tuning).Event Inputs• With the E5@N-@@@B, the following functions can be executed usingevent inputs: switching set points (multi-SP, 4 pts. max.), switching RUN/STOP status, switching between automatic and manual operation, andstarting/resetting program.Heater Burnout and HSAlarms• With the E5@N-@@H@ and E5@N-@@HH@, the heater burnout detectionfunction and the HS alarm function can be used.CommunicationsFunctions• Communications functions utilizing CompoWay/F (See note 1.), SYSWAY(See note 2.), or Modbus (See note 3.) can be used.E5@N-@@@03: RS-485 interfaceE5@N-@@@01: RS-232C interface (See note 4.)Note(1) CompoWay/F is an integrated general-purpose serial communicationsprotocol developed by OMRON.
It uses commands compliant with thewell-established FINS, together with a consistent frame format onOMRON Programmable Controllers to facilitate communications between personal computers and components.(2) SYSWAY communications do not support alarm 3 output.(3) Modbus is a communications control method conforming to the RTUMode of Modicon Inc.'s Modbus Protocol.(4) The E5CN and E5CN-U do not support the RS-232C interface.External Power Supply forES1BThe E5@N-@@P can be used as the power supply for ES1B Infrared Temperature Sensors.The external power supply for the ES1B cannot be used on the E5CN-C@@(Current Output Model).9Section 1-3Setting Level Configuration and Key Operations1-3Setting Level Configuration and Key OperationsParameters are divided into groups, each called a “level.” Each of the set values (setting items) in these levels is called a “parameter.” The parameters onthe E5CN/CN-U/AN/EN are divided into the following eight levels.When the power is turned ON, all of the display lights for approximately onesecond.Power ONStarted in manual mode.Started in automatic mode.Press the O Keyfor at least 1 s.Operation LevelCManualmode(Seenote3.)Press theO Key less than 1 s.a-mPress the O Keyfor at least 1 s;display will flash.Press the O Keyfor at least 3 s whilea-m is displayed.Manual ControlLevelPress the O +M keys; displaywill flash.Adjustment LevelPress theO Key forat least 1 s.

You must turn OFF the power supply.(3) From the manual control level, key operations can be used to move to theoperation level only.Level10Protect levelControl in progressControl stoppedCan be set.---Operation levelAdjustment levelCan be set.Can be set.-----Manual control levelInitial setting levelCan be set.-----Can be set.Advanced function setting levelCalibration level-----Can be set.Can be set.Communications setting level---Can be set.Setting Level Configuration and Key OperationsSection 1-3Of these levels, the initial setting level, communications setting level,advanced function setting level, and calibration level can be used onlywhen control is stopped. Control outputs are stopped when any ofthese four levels is selected.Protect Level• To switch to the protect level from either the operation level or the adjustment level, simultaneously hold down the O and M keys for at least 3seconds.
(See note.) This level is for preventing unwanted or accidentalmodification of parameters. Protected levels will not be displayed, and sothe parameters in that level cannot be modified.NoteOperation LevelThe key pressing time can be changed in “move to protect levelmove” parameter (advanced function level).• The operation level is displayed when the power is turned ON. You canmove to the protect level, initial setting level, or adjustment level from thislevel.• Normally, select this level during operation.
While operation is in progress,items such as the PV and manipulated variable (MV) can be monitored,and the set points, alarm values, and alarm upper and lower limits can bemonitored and changed.Adjustment Level• To move to the adjustment level, press the O key once (for less than 1 s).• This level is for entering set values and offset values for control.
In addition to AT (auto-tuning), communications write enable/disable switching,hysteresis settings, multi-SP settings, and input offset parameters, itincludes HBA, HS alarm, and PID constants. From the adjustment level, itis possible to move to the top parameter of the initial setting level, protectlevel, or operation level.Manual Control Level• When the O key is pressed for at least 3 seconds from the operationlevel's auto/manual switching display, the manual control level will be displayed. (The MANU indicator will light.)• This is the level for changing the MV in manual mode.• To return to the operation level, press the O key for at least one second.Initial Setting Level• To move to the initial setting level from the operation level or the adjustment level, press the O key for at least 3 seconds.
The PV displayflashes after one second. This level is for specifying the input type andselecting the control method, control period, setting direct/reverse action,and setting the alarm types. You can move to the advanced function setting level or communications setting level from this level. To return to theoperation level, press the O key for at least one second. To move to thecommunications setting level, press the O key for less than one second.(When moving from the initial setting level to the operation level, all theindicators will light.)NoteAdvanced FunctionSetting LevelPressing the O key for at least 3 seconds in the operation level'sauto/manual switching display will move to the manual control level,and not the initial setting level.• To move to the advanced function setting level, set the “initial setting/communications protect” parameter in the protect level to 0 and then, in theinitial setting level, input the password (−169).• From the advanced function setting level, it is possible to move to the calibration level or to the initial setting level.11Section 1-3Setting Level Configuration and Key Operations• This level is for setting the display auto-return time, event input assignments, standby sequence, and alarm hysteresis, and it is the level formoving to the user calibration.Communications SettingLevel• To move to the communications setting level from the initial setting level,press the O key once (for less than 1 s).
When using the communicationsfunction, set the communications conditions in this level. Communicatingwith a personal computer (host computer) allows set points to be readand written, and manipulated variables (MV) to be monitored.Calibration Level• To move to the calibration level, input the password (1201) from theadvanced setting level. The calibration level is for offsetting error in theinput circuit.• You cannot move to other levels from the calibration level by operating thekeys on the front panel. To cancel this level, turn the power OFF then backON again.1-3-1Selecting Parameters• Within each level, the parameter is changed in order (or in reverse order)each time the M key is pressed.
