The default is 2: Upper limit. Auxiliary outputs are allocated for alarms. ON delays and OFF delays 0 to s can also be specified. Note: For models with heater burnout, SSR failure, and heater overcurrent detection, alarm 1 will be an OR output of the alarm selected from the following alarm types and the alarms for heater burnout, SSR failure, and heater overcurrent. When using a grounding thermocouple, do not connect any of the control output terminals to ground. If the control output terminals are connected to ground, errors will occur in the measured temperature values as a result of leakage current.

Easy, Dependable, Complete Functionality, and segment Displays. Controllers now available with analog inputs. Faster sampling at ms. Transfer output provided for easy output to recorders. Voltage outputs to drive SSRs for both heating and cooling control. Can be used for alarms to provide three alarm outputs.
Models available with three-phase heater burnout detection and SSR fault detection. Easy setting with segment displays. Connect to either a thermocouple or platinum resistance thermometer with the same model. Easily see the status from a distance with PV display with three- color switching function. Setting protection indicator informs operator when protection is enabled. Manual output provided. Controller available with long-life relay output available soon. Note: Refer to Precautions on page Note: Refer to page 19 for information on changes in comparison to previous models.
Features Improved Functions for a Wider Range of Application Control Analog Values, such as Pressures, Flowrates, and Levels The new E5CN Series now also includes models that accept analog inputs, enabling control applications other than for temperature, including pressure, flowrate, level, humidity, and weight control. This enables the new E5CN to handle application requiring even greater response speed and accuracy. Voltage outputs can be used for both heating and cooling for Models with Two Control Outputs.
Also, control output 2 can be set for use as an alarm output, to enable using up to three alarm outputs. Multi-input Capability with One Controller Connect to either a thermocouple or platinum resistance thermometer with the same model. Model selection is simplified, stocks are reduced, and fewer maintenance parts are required. Number of alarms Blank: No alarm 2: Two alarms 3. Option Unit M: Option Unit can be mounted 4.
Be sure to refer to the following user manuals for application precautions and other information required for operation before attempting to use the product.
Output type R: Relay Q: Voltage 2. Number of alarms Blank: No alarm 1: One alarm 2: Two alarms 3. ECT3 E5CN-R2T: 3. E5CN-R2T: 2.
Non-contact input ON: Residual voltage: 1. Outflow current: Approx. See note 4. 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.
Set value: 12, LBA can be set only for alarm 1. Set the alarm types for alarms 1 to 3 independently in the initial setting level. The default setting is 2 upper limit. Control period 0. Platinum resistance thermometer: 0. Insulation resistance 20 MW min. When robust tuning RT is ON, the differential time is 0. B, R, and S sensors: 0.
Minimum detection ON time: ms See note 1. SSR failure detection alarm setting range 0. Minimum detection OFF time: ms See note 2. Note: 1. If the ON time of control output 1 is less than ms, heater burnout detection and the heater current will not be measured.
If the OFF time of control output 1 is less than ms, SSR failure detection and the heater current will not be measured. A voltage output control output is not electrically insulated from the internal circuits. When using a grounding thermocouple, do not connect any of the control output terminals to ground.
If the control output terminals are connected to ground, errors will occur in the measured temperature values as a result of leakage current.
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 suitable for the maximum operating voltage.
If an input error output is enabled, the a operation indication on the front The input power supply depends on the power supply specification of the Controller and is panel will not light and s. Terminal applications depend on the model of the Option Unit. A 3 9 Do not connect. See page If an input error output is enabled, the al-1 operation indication on the front panel will not light and s.
Temperature unit Operation indicators Level Key No. Recommended panel thickness is 1 to 5 mm. Group mounting is not possible in the vertical direction. Maintain the specified mounting space between Controllers. To mount the Controller so that it is waterproof, insert the waterproof packing onto the Controller.
When two or more Controllers are mounted, make sure that the surrounding temperature does not exceed the allowable operating temperature specified in the specifications. Armature 12 dia. Plug Approx. Back-connecting Socket P3GA 27 dia. Using any other sockets will adversely affect accuracy. Use only the specified sockets. 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. Level Key for Press the Level Key at least 1 s. See See for at least 3 s while note 3. Press the Level Key for at least 1 s 25 for at least 1 s; display will flash. Control stops. Press the Level Key for less than 1 s. Input password. Set value? Set value Calibration Level See note 2. Operation level entered for software reset. 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. You can move only to the operation level by operating the keys on the front panel from the manual control level. Press the Level Key less than 1 s. Display flashes for at least 1 s. Starting in automatic mode Operation Level Set either of these parameters. Set either of these parameters. Adjustment level l.
Press the Level Key for at least 3 s. C 25 Process value Added when PV display is added. Display flashes. Communications Setting Level The time taken to move to the protect level can be adjusted by changing the "Move to protect level time" setting. Displayed only for models with communications. Changes are effective after cycling power or after a software reset.
