1. If present
All alarms will be stored as follows:
• the “TEMPERATURE“ display shows the alarm number, for
example “AL 1“, “AL 2“, etc.,
• whereas the “TIME“ display shows the ALARM CODE, for
example “E1“, “b1“, etc.
If no alarm is active: When the button is pressed, the first
alarm, i.e. the last to occur, is displayed. Press the button again
to go to the next alarm, and likewise to scroll all the stored
alarms. After displaying the last alarm, the message “——”
appears on the display and after 5 seconds the unit automati-
cally returns to the main menu. When the next alarm occurs,
the current ones will be deleted (automatic reset). If an alarm is
active, pressing the button silences the buzzer and
displays the alarm message. Press the button again to go to
the next alarm, and likewise to scroll all the stored alarms. After
displaying the last alarm, the message “——” will appear on
the display and after 5 seconds the unit automatically returns
to the main menu. No cancelling from the memory (i. e. no
reset) occurs when alarms are active.
To cancel the alarms, press + together for 5 seconds.
CAUTION
The reset function is disabled if the
operator did not see the stored alarms
and the message “RES“ appears on the
“TEMPERATURE“ display.
K HACCP CONNECTIONS (ACCESSORIES)
NOTE!
Refer to the handbook enclosed with the kit for
instructions on installing the accessories.
The board has a serial communication line for interacting with
other units or an HACCP network control station.
It can be connected:
• directly to a device that communicates in TTL (e. g. the
FT190ELX printer), by setting the parameter E485=“Prn“
• to an RS485 communications network, by setting the
parameters E485=“PC“ and PRTY=“1“ (refer to the hand-
book supplied with the kit) inserting the conversion card
RS485-LK-P and Adr=“Network address“.
