D/W CNTRL to DIAG: This display is
mainly for maintenance and fault finding.
PLC inputs status is displayed with values
of the controller’s internal temperature, the
temp.sensors, the scan time, RAM status
and battery status and ID info.is shown.
For bench models, the D/W RTD (temp.
sensor) value will show open circuit value
– but can be ignored.
If memory corruption should occur, if
‘RESTORE DEFAULTS’ is held depressed
(for 5 seconds) until the red LED comes
ON then OFF, the memory is re-loaded
with current data stored in a special area
of memory. This avoids keying in all the
program data again.
DIAGNOSTIC 1 display
DIAG to DIAG2: As above, this display is
for maintenance and fault finding. The
status of the PLC outputs is displayed
including the counts and flow rate from the
dispensing flow meter (floor models only).
The PLC drives the magnetic stirrers, the
alert beeper and d/w dispensing pump so
that each is adjustable. The value applied
to each device is monitored on this display.
4000 is the max value possible.
DIAGNOSTIC 2 display
DIAGNOSTIC 3 display
DIAG2 to DIAG3: As above, this display
is for maintenance and fault finding and it is
used when the bath is not in cycle.
Each rung of the display can be a press
button to force on each device. Other
rungs monitor most input devices. The UP
and DOWN status of the floats on the water
level switches is monitored.
If there is suspicion that a particular device
is not operating, it can easily be proven on
this screen. During manufacture it is used
as a check that each device is wired
correctly.
BACK will return you to the Diag 2 screen.
EXIT returns to the SELECTION display.
