15 USER CONFIG
8: Display shows ‘8 0’ – Restore Factory Settings
This mode allows the operator to restore the instrument to the factory set points. This includes all
calibrations, alarms and baud rates. To perform this function, press the “UP” button until the display shows
8 88, then press the mode button. If you do not wish to perform the factory restore, press the mode button
with any other number on the display.
16 FPT - Front panel test
The FPT is available from the keyboard to allow the factory and users to quickly determine if the front panel is
working correctly. To enter the FPT, press and hold both the INC and DEC keys. Th
e display will show ‘ –- ‘ until
the INC and DEC keys have been held for 10 seconds. The display will then change to ‘ ---‘. Upon entry to the
FPT, the serial port will output:
“Entering Lamp Test.” and the display will begin displaying characters, one at
a time. If you press the front panel INC key (or the PCB INC key) the display will show ‘ UUU’. Pressing the
DEC key results
in ‘ ddd’ and pressing the MODE key shows ‘ ===’. To exit the FPT, press and hold both the
INC and DEC keys until ‘ - - -‘ is shown, then release the INC and DEC keys to resume normal operation.
17 If a computer is on line with the analyzer, a restart may be accomplished either by
simultaneously holding the “mode” and “UP” buttons on the model 3100 analyzer display
panel for approximately 10 seconds or by turning the analyzer off and then on.
Er.0 Starting a System for the first time
Two identical co
pies of the system’s setup information are stored
in the EEPROM. If both copies are damaged (the program
determines this by inspecting the CRC16 of the data) the device
will refuse to run. ‘ Er.0’ will be displayed on the front panel and
the device is locked with the fault light and relay ON.
The only way out of this error is to perform a factory initialization
that can be reached through the Setup Mode with a serial terminal.
C.3
To change the factory settings through the Software Interface
(RS-232 port):
Use a terminal or terminal emulator (like the Windows 95 HyperTerminal) to interactively
test and configure the an
alyzer. See Section “Service Port” of this manual. Connect your
terminal, set the communications parameters to 9600 baud, 8 data bits, 2 stop bits, no
parity, no hardware or software handshaking. Terminal emulation must be VT100 or
VT200.
Turn on the ana
lyzer’s power and wait for the Software Version number to be displayed.
The terminal emulator should then display @@@ then the Model, serial number, version
number and the baud rate.
Regardless of the serial output format previously selected, type SETUP and press enter
from the Terminal emulator.
The instrument will enter the User Setup Menu and the instrument display will show ‘ SU ’.
