C
- COUNTING MODE. Permits the user to choose the UP or
DOWN mode, ie. whether the display must show the time which has
passed or the remaining time. The options are:
1 = UP mode
2 = DOWN mode
b
- BACK-UP MODE. This parameter determines the instrument
reaction in the case of power failure. The options are:
1 = Timer stops and memorized the counting current value
2 = Timer goes on counting (only with internal battery present and
enabled)
3 = Timer reset the counting
When option 1 has been chosed, the instrument goes off and the
counting current value is saved. When the power supply is restored,
the timer can will start working from the saved value.
When option 2 has been chosed, in the case of power failure the
display and the output will go off, but the timer will continue to count.
Note that the mode 2 is enabled only if the internal battery is present
and activated by the connection of relative terminal blocks (see
electrical connections).
Under these conditions of operation the display results turned on but
with an inferior brightness to the normal mode
We recommends to disable the battery when it is not necessary.
In case 3 finally, at the missing of power supply, the instrument
stops the counting and does not memorize the reached value, so
that at the returning of power supply the instrument will be in the
reset conditions.
E
- CNT EN INPUT OPERATING MODE. Allows the user to select
the operating mode of the Count Enable (CNT EN) external input.
The options are:
1 = Bistable Start/Stop
2 = Bistable Reset-Start/Stop
3 = Monostable Start/Stop
4 = Monostable Reset-Start/Stop
t
- T KEY OPERATING MODE: This parameter permits to decide the
operating mode of the frontal T key and the possibilities are:
0 = Key disable
1 = RESET-START/STOP
2 = RESET/START/STOP
3 = RESETonly
6 - PROBLEMS, MAINTENANCE AND WARRANTY
6.1 – CLEANING
It’s raccomanded to clean the instrument only with a cloth welted
with water or with a detergent neither abrasive nor containing
solvents.
6.2 – WARRANTY AND REPAIRS
The instrument is under warranty against construction vices or
defected material, noticed within 12 months from delivery date. The
warranty is limited to the repairs or to the substitution of the
instrument. The eventual opening of the housing, the violation of
the instrument or the wrong use and installation of the product
means the automatic decay of the warranty.
In case of defected instrument, noticed in warranty period or out of
warranty, do contact our sales department to obtain the shipment
authorisation.
The defected product must be shipped to TECNOLOGIC with the
detailed description of the failures found and without any fees or
charge for Tecnologic, safe different agreements.
