Setting lock: Lock 1 (
), Lock 2 ( ) or OFF ( ) on the SV display. Lock 1 mode can lock all
settings and Lock 2 mode only can lock others than SV value. When OFF mode is selected, the Lock
function will be OFF. If you press
and key simultaneously, the “Lock” status can be released and
the controller will be back to the previous display.
OFF
OUT: Output value display and output value adjustment in manual tuning control (This function is not
available in ON/OFF control or Auto-tuning setting)
0
CT: In case of using an external current transformer (CT), the controller displays the current value being
measured by CT, if the control output is ON
Read only
2. Regulation Mode: Set the control parameters
LED Display Explanation Default
AT: Auto-tuning setting. When AT key is set to ON (
), the execution of the PID auto-tuning function is
automatically started. (PID control)
OFF
