(13) : The alarm relay can be energized continuously (by se-
lecting “LE” for “level”) or with a pulse (by selecting “PULS”
for “pulse”) . The pulse length is fixed to about 5 seconds .
(14) : When the instrument is configured as ORP controller
some of the above items or the item values are not anymore
available to the user .
(15) : Relay 3 an relay 4 must be both set to “ACLE” in
order to have the advanced cleaning enabled . If only one
of them is set to “ACLE” then it will behave as it were set to
“OFF” . When the advanced cleaning is enabled, relay 3 is
used for water pouring while relay 4 is used for detergent
pouring .
(16) : “HOLd” and “USEr” are effective only when “O .10”
and “O .20” are set to “rECO” . In the other cases the analog
output is set automatically to the minimum value upon hold
mode (i .e . “O .14”, “O .15” and “O .24”, “O .25” have no
effect if “O .10” = “SEt” and “O .20” = “SEt” respectively) .
(17) : “measured value” is the reading value with a null
reading offset adjustment .
(18) : if the device is set for MTC (item G .01 to “USEr”) then
items F .10 and F .11 cannot be modified nor seen . When
item G .01 is changed from “AtC” into “USEr”, item F .11
is automatically zeroed .
(19) : When the relay set to “SCLE” is set to something else,
the simple cleaning action, if in progress, is aborted im-
mediately . When relay 3 or relay 4 or both of them are set
to something else than “ACLE”, and the advanced clean-
ing is in progress, cleaning is aborted immediately (but a
complete rinsing phase is done before the actual end of the
cleaning session) . Only one relay can be set to “SCLE” or,
alternatively, relay 3 and 4 can be set to “ACLE” . Only one
relay can be set to “HOLd” . If these rules are not respected,
the display shows “WRONG” .
(20) : These items do not vary when the pH/ORP input
selection (“G .00”) is changed .
(21) : If the relay 1 mode or the relay 2 mode is set to “SEt1”,
the analog output 1 mode can not be set to “SEt” and vice
versa . Similarly, if the relay 1 mode or the relay 2 mode is
set to “SEt2”, the analog output 2 mode can not be set to
“SEt” and vice versa .
