3-wire circuit, cable resistance compensation.
Excitation current: 170µA.
PID CONTROL:
• User-selectable as: ON-OFF w/ adjustable hysteresis, or manual P, PI, PID and
PID-Autotune.
• Proportional Band (Pb): 0 = ON/OFF control; or 1% to 500% of maximum input
span.
• Integral (Ir): 0 = off; or 0.01 to 25.00 rep/minutes
• Derivative (Dt): 0 = off; or 1 to 250 seconds.
(Figure 2)
• Cycle-Time: 0.5 to 99.9 seconds (for PWM-PID output control).
• PID-Autotune: start from the front panel.

When the controller is initially energized, the firmware version is displayed
for approximately 4 seconds, after which the controller starts normal
operation. The values of PV (temperature), and SV (setpoint) are displayed
and the outputs are enabled after 6 seconds.
