Section 1-2 I/O Configuration and Main Functions 1-2-2 Main Functions This section introduces the main E5CN/CN-U/AN/EN functions. For details on particular functions and how to use them, refer to SECTION 3 Basic Operation and following sections.
I/O Configuration and Main Functions Section 1-2 • When the “input error output” parameter is set to ON, alarm output 1 turns ON 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 using event inputs: switching set points (multi-SP, 4 pts. max.
Section 1-3 Setting Level Configuration and Key Operations 1-3 Setting Level Configuration and Key Operations Parameters are divided into groups, each called a “level.” Each of the set values (setting items) in these levels is called a “parameter.” The parameters on the 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 one second. Power ON Started in manual mode. Started in automatic mode.
Setting Level Configuration and Key Operations Section 1-3 Of these levels, the initial setting level, communications setting level, advanced function setting level, and calibration level can be used only when control is stopped. Control outputs are stopped when any of these 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 3 seconds. (See note.
Section 1-3 Setting 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 for moving to the user calibration. Communications Setting Level • 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 communications function, set the communications conditions in this level.
Section 1-4 Communications Function • When you turn the power OFF, you must first fix the settings (by pressing the M key). The settings are sometimes not changed by merely pressing the U or D keys. 1-4 Communications Function The E5CN/AN/EN is provided with a communications function that enables parameters to be checked and set from a host computer.

Appendix A Timing During operation Status Overshooting Undershooting Hunting Temperature is not rising Meaning ON/OFF control is enabled (default: ON/OFF control selected). Countermeasures Select PID control and execute either ST (self-tuning) or AT (auto-tuning). When using self-tuning, turn ON the power supply to the Temperature Controller and load (heater, etc.) at the same time, or turn ON the load power supply first.
Appendix A Timing During operation (continued) Status Temperature error is large Input error (S.err display) Meaning Thermometer has burnt out or short-circuited. Thermometer lead wires and power lines are in the same conduit, causing noise from the power lines (generally, display values will be unstable). Connection between the Temperature Controller and thermocouple is using copper wires. Installation location of thermometer is unsuitable.
