Note The PT Status Control bits remain unchanged if the PT status is changed with
Another method of restoring the screen is to display a screen using the Screen
Switch setting bit.
The Alarm Output bit turns on and off the ALM OUTPUT terminals at the rear of
the PT.
Alarm Output control with Bit 14 is enabled only when the alarm output is turned
on with the PT memory switches.
Refer to the appropriate PT Operation Manual and the NT-series Support Tool
Operation Manual for more details.
The continuous buzzer sounds continually without interruption.
The intermittent sounds for 0.5 s at 0.5 s intervals.
If both Bit 13 and Bit 12 are turned ON simultaneously, Bit 13 takes priority and
the continuous buzzer is selected.
Buzzer control with these bits is enabled only when the buzzer is turned on with
the PT memory switches.
Refer to the appropriate PT Operation Manual and the NT-series Support Tool
Operation Manual for more details.
The Initialize Display History initializes the display history stored in the PT.
The display history is initialized when Bit 11 is set from 0 (OFF) to 1 (ON). Bit 11
reverts to 0 (OFF) after the display history is initialized.
The NT20M allows backlighting to be controlled as follows using combinations
of Bit 10 and Bit 8.
When backlighting is turned OFF (Bit 15 is set to 0 (OFF)), the backlight color
(red or white) and backlight mode (continuous or flashing) are invalid.
In addition to the PT Status Control Area, the PT status can be controlled by set-
ting the screen attributes with the Support Tool, as follows:
In addition, the display (or backlighting) is turned off if the PT is unused for a cer-
tain time if the PT memory switches are set to enable the burn-in prevention fea-
ture (EL display version) or the backlight control feature (LCD display version).
Refer to the appropriate PT Operation Manual and the NT-series Support Tool
Operation Manual for more details.
