E5CN E5CN Nomenclature E5CN Operation Indicators 1. AL1 (alarm 1) Lights when alarm 1 output is ON. AL2 (alarm 2) Lights when alarm 2 output is ON. 2. HB (heater burnout alarm display) Lights when a heater burnout is detected. The heater burnout alarm remains ON by setting the heater burnout latch. To reset, turn the power supply OFF and then ON or set the heater burnout alarm value to “0.0A.” 3.
E5CN E5CN Operation INITIAL SETUP On previous Controllers, sensor input type, alarm type and control period were set on DIP switches. These hardware settings are now set in parameters in setup menus. The and keys are used to switch between setup menus, and the amount of time that you hold the keys down determines which setup menu you move to. This section describes two typical examples. Note: On the E5GN, the Key is the 1. ON/OFF Control Typical Application Examples Key.
E5CN E5CN 2.

E5CN E5CN Communications Setting Level Calibration Level To select this level, press the key once for less than one second in the initial setting level. When the communications function is used, set the communications conditions in this level. Communicating with a personal computer (host computer) allows set points to be read and written, and manipulated variables to be monitored. To select this level, you must enter the password (“1201”) in the advanced function setting level.
E5CN E5CN SPECIFICATION SETTING (AFTER TURNING ON POWER) Initial Setting Level This level is used for setting basic specifications of the Temperature Controller. Using this level, set the input type for selecting the input to be connected such as the thermocouple or platinum resistance thermometer and set the range of set point and the alarm mode.

E5CN E5CN TROUBLESHOOTING When an error occurs, an error code will be displayed on the No. 1 display. Check the contents of an error and take appropriate countermeasures. Type of error Countermeasures Input error Check the wiring of inputs for miswiring, disconnections, short-circuits, and the input type. Memory error First, turn the power OFF then back ON again. If the display remains the same, the Unit must be repaired.

E5CN E5CN Installation SETTING UP OPTION BOARDS If communications, event input, or heater burnout functions are required, mount the E53-CNH03 Communications Board or the E53-CNHB Event Input Board. The heater burnout function is supported on either of these two Option Boards.
E5CN E5CN WIRING TERMINALS The voltage output (control output) is not electrically insulated from the internal circuits. When using a grounding thermocouple, do not connect the control output terminals to the ground. If the control output terminals are connected to the ground, errors will occur in the measured temperature values as a result of leakage current. Voltage Output Control output Relay Output Standard insulation is applied to the power supply I/O sections.
E5CN E5CN Precautions OPERATING ENVIRONMENT • • • • Use the Temperature Controller within the rated operating temperature, storage temperature, and operating humidity specified for each model. Use the Temperature Controller according to the performance specifications such as vibration, shock, and degree of protection specified for each model. Do not use the Temperature Controller in places where it is subject to dust or corrosive gases.
