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.
