Main Functions

This section introduces the main E5CC/E5EC functions. For details on particular functions and how to
use them, refer to Section 3 Part Names and Basic Procedures and following sections.
Input Sensor Types
You can connect the following sensors and signals to the universal input.
Thermocouple:
Resistance thermometer:
Infrared temperature sensor:
Current input:
Voltage input:
Control Outputs
• A control output can be a relay, voltage (for driving SSR), or current output, depending on the
model.
Adjusting PID Constants
• You can easily set the optimum PID constants by performing AT (auto-tuning) with the limit cycle
method or by performing ST (self-tuning) with the step response method.
Alarms
Standard Alarms
• You can output an alarm when the deviation, process value, set point, or manipulated value
reaches a specified value.
• You can also output alarms for the PV rate of change and for loop burnouts.
• If necessary, a more comprehensive alarm function can be achieved by setting a standby
sequence, alarm hysteresis, auxiliary output close in alarm/open in alarm, alarm latch, alarm ON
delay, and alarm OFF delay.
HB and HS Alarms
• With models with the optional HB and HS alarms, you can detect heater burnout and heater short
alarms based on CT inputs.
Integrated Alarm
• You can output an integrated alarm if a standard alarm, HB alarm, or HS alarm turns ON.
Event Inputs
• With any E5CC/E5EC model that supports event inputs, you can use external contact or
non-contact inputs to achieve any of the following functions: Switching set points (Multi-SP No.
Switch, 8 points max.), switching RUN/STOP, switching between automatic and manual operation,
inverting direct/reverse operation, 100% AT execute/cancel, 40% AT execute/cancel, setting
change enable/disable, communications write enable/disable, and canceling the alarm latch.
