Programming the TPRG SPA
The Temperature Input SPA operating parameters
are set, and the settings stored in on-board, non-
volatile EEPROM. There are four push buttons on the
unit front panel; VIEW, SELECT, an UP arrow, and
a DOWN arrow. Together with the prompting mes-
sages displayed on the LCD, these are used to access
menus, and to view and change the settings for:
•
Input Sensor Type and Range
•
Engineering Units Displayed, and other Options
•
Alarm Functions (Trip points, etc.)
•
Password (Menus/Settings Security)
•
“Smart Ranged” Zero and Full Scale
(AO/AOZ-equipped units only)
•
Standard Ranged Zero and Full Scale
(AO/AOZ-equipped units only)
•
Analog Output Trim
(AO/AOZ-equipped units only)
Main Menu/View Settings
Figure 5 gives an overview of the first level of menus
used to configure the TPRG SPA.
On power-up, the SPA defaults to a display of the
measured value. Pressing the VIEW button accesses
a series of displays that show, in succession, the set-
tings currently stored in unit memory (see Figure 6).
Depending upon whether or not the Security Jumper
has been installed (see Figure 2), SELECT will access
either the first screen in the main configuration menu,
“CONF SENS”, or the password code query screen,
“ENTR PASS”.
Once the Main Menu has been accessed, the up and
down arrow buttons are used to move through all of
the sub-menus in a loop. Pressing the SELECT button
accesses the first screen of the sub-menu shown on
the LCD.
