Programming of function
and/or time range
Press FUNC and TIME but-
tons simultaneously for
approx. 3 s. When display
shows "- - -" release switches
and press immediately FUNC
or TIME respectively for pro-
gramming function number
and/or time.
Programming of function
In programming mode, press
TIME to increment right flas-
hing digit. Press FUNC to pro-
ceed to next digit and TIME to
increment it, etc. Press FUNC
to end programming se-
quence. If a higher number
than 22 is selected for functi-
on, the display show "Err".
After approx. 3 s the display
returns to the last selected
function and a new function
number can be selected.
Programming of time
In time programming mode,
press TIME to increment first
flashing digit. Press FUNC to
go to next digit. Press TIME
again to increment this digit,
etc.
To select decimal point, press
FUNC and TIME to change
position (xxx. or xx.x or x.xx).
To select time range, press
FUNC and press TIME to
change position of time range
indicator on the display (S for
seconds, M for minutes, H for
hours). Press FUNC to accept.
If a recycler function has been
selected, press FUNC to set
second time value after the
same criteria as above.
Finally, press FUNC to end
programming sequence.
Status of time/function
During operation the selected
function and time values may
be read without disturbing the
operation.
Status of selected function
Press FUNC. The display
shows function number.
When the button is released,
the display returns to current
time value.
Status of selected time
Press TIME. The display
shows selected time value.
For recyclers press TIME
twice to read second time
range. When the button is re-
leased, the display shows
selected time range for
approx. 3 s before returning
to current time value.
