Main Functions

For details on particular functions and how to use them, refer to Section 3 Part Names and Basic Proce-
dures and following sections.
Input Sensor Types
You can connect the following sensors and signals to the universal input.
Thermocouple (temperature input):
Resistance thermometer (temperature input):
Infrared Temperature Sensor (temperature input):
Current input (analog input):
Voltage input (analog input):
Control Outputs
• A control output can be a relay output, voltage output (for driving SSR), or linear 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.
• You can also add RT (robust tuning) to give priority to controlling stability.
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 model that supports event inputs, you can use external contact or transistor 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, starting/resetting the
program, inverting direct/reverse operation, switching the SP mode100% AT execute/cancel, 40%
AT execute/cancel, setting change enable/disable, communications write enable/disable, and
canceling the alarm latch.
