8.8 Diagnostic Interactions
The US Autoflow has two types of general diagnostic methods, Power-up self-test and Diagnostic Mode tests.
8.8.1 Power-Up Self Test
The power-up self-test is comprised of the following sequential tests:
1) Tests all main control board memory.
2) Verifies its non-volatile memory (EEPROM) and displays the current version of program.
3) The digital displays of systems that are active will blink until either the run/setup key is pressed
to Setup and back to Run or the [SEL] key is pressed.
8.8.2 Diagnostic Mode Tests
The Diagnostic Mode allows the operator to configure and/or check the Incubator for input/output
signals manually and individually. The diagnosis mode has three menus to select from that are
following:
• Tst - test output parameters
• Opt - option configuration parameters
• Rst - reset, master
To initiate the diagnosis mode, perform the following:
a) Press and hold Hidden key (flag on NuAire logo) for four seconds (in either Run or Setup mode),
the temperature display will indicate the first menu “tst”
b) To advance to second menu, press key, temp. display will indicate “opt”
c) To advance to the third menu, press key, temp. display will indicate “rst”.
d) To repeat the menus, continue to press the which will advance the menus in a round robin
fashion.
e) To enter to desired menu, press the SEL key while desired menu is indicated on temp. display.
The “tst” and “opt” menus each have several function parameters as described below. The “rst” menu
performs a master reset function which clears the microprocessor’s memory and reset all parameters
to their default conditions.
To enter the function parameters, press the SEL key while the temp. display indicates the desired menu.
Then, while in the menu, press SEL key to advance through the function parameters, again, in a round
robin fashion. Once in the desired function parameter, press the or key to alter or toggle on/off.
To exit the diagnostic mode at any time, press the Hidden key several times.
