• Sets time to backlight from no operation status until backlight is
switched off.
When set to 0, the backlight remains ON.
Backlight relights by pressing any key while backlight is OFF.
• Setting range: 0 to 99 minutes

1
• Sets amount of deviation for the positive (or negative) side of one
division of the bar graph. (See p.51.)
• Setting range: 1 to Converted value of 20% of input span
[PID zone function]
When PID zone function “Used” is selected, and if SV (or Step SV for the program
control) is lower than PID zone value, the control is performed with PID zone
parameters of the relevant PID zone value.
If the next PID zone value is lower than the current one, the next PID zone
parameters will not be effective.
During program control, the currently performing step SV is applicable to the PID zone.
In the case of (Fig. 6.3.9-1), “SV: 150 ” is higher than “PID zone value 1: 100 ”,
and lower than “PID zone value 2: 200 ”, so control is performed using PID zone
parameters of PID zone value 2.
As PID zone value 4 has not been set, even in the case SV is higher than PID zone
value 3, control is performed using PID zone parameters of PID zone value 3.

SV change
Controls using PID zone
parameters of PID zone
value 2.
Controls using PID zone
parameters of PID zone
value 3.
Controls using PID zone
parameters of PID zone value 1.
Controls using PID zone
parameters of PID zone value 2.
Controls using PID zone
parameters of PID zone value 3.
If PID zone value 4 has not been set, for the zone which is
higher than the PID zone value 3, control is performed using
parameters of PID zone value 3.
