Protect Switch
• When the protect switch is ON, Up Key and Down Key operations
are prohibited to prevent setting mistakes.

switch is ON.
(The display can be switched between the process value, set point,
alarm value, and input shift value.)
• The default is OFF.
●
INIT Switch

normal operation, make sure this switch is turned OFF.

• All switches are OFF for the default settings.
• The hysteresis when using ON/OFF control is 0.2% FS (multi-input
(thermocouple/platinum resistance thermometer) models: 0.1% FS).
• When 2-PID control is set, optimum PID parameters are set
automatically and controlled using ST (self-tuning).
•
When the input shift display is disabled, the input shift is not displayed,
but is enabled.
To disable input shift, set the input shift value to H0.
The default setting for the input shift is H0.
• When using thermistor input, the setting for switch 5 is ignored.
