3.3.8.
Calibration incomplete
If the calibration is not completed the display will continually flash th
e “incomplete calibration” error (section 3.1.3),
during all subsequent power cycles. This indicates that a calibration was attempted but never completed.
Recalibrate the display completely to remove this error condition.
3.4. Self test
The ITL40 can check its hardware for proper operation by entering the password
RLLR LLRR.
The display will turn all the LEDs ON and then cycle each LED OFF individually starting with the top LED. All LEDs
will come on and begin flashing between full bright and the calibrated dim level for 5 seconds. The display will then
scroll text indicating the self test condition.
Memory test
“MEM-PASS”
Memory (EEPROM) is good.
“MEM-FAIL”
Memory (EEPROM) failure detected.
Sensor signal test (MASTER unit only)
“SIG-PASS”
Sensor signal voltage within tolerance (0.4 volts to 4.8 volts).
“SIG-FAIL”
Sensor signal voltage out of tolerance (0.4 volts to 4.8 volts).
Communication wire test
‘WIRE-PASS”
Data communication lines good.
“WIRE-FAIL”
Data communication lines shorted or open.
If the self test password is used on a MASTER display all REMOTE displays will also perform their self test.
3.5. Setting the dim LED level
The display can be dimmed by applying system power to pin 4 (Dim Display input). The ITL40 has 9 levels of
brightness available (9 = brightest, 1 = dimmest, default value is 3).
To select the dim level of the display use the magnetic switches to enter the password
RLLR LLLR.
All of the LEDs will be illuminated during the set-up. Touch a magnet against the
RIGHT
switch and the display will
dim to the next level and show the dim value number (9 through 1). Release the magnet and again touch it against
the
RIGHT
switch again to drop to the next dim level. Once the dim level is at the dimmest setting (1) the next touch
of the magnet will cycle to the highest dim level (9).
When the dim level is at the desired point activate the
LEFT
switch to save and exit.
3.6. Show software version, device settings, and errors
The ITL40 can display its setting by entering the password
RRRR RRRR.
The display will scroll the software version, unit type, communication method, and then display any errors.
Software version
“Vx.x”
Where x.x equals the numeric software version. For example, V1.0.
Unit type
“MASTER”
The unit is set as a MASTER.
“REMOTE”
The unit is set as a remote.
“CAL INCOMPLETE” A calibration was started but never completed.
“UNKNOWN”
The unit type cannot be determined
– ERROR.
