Important; Description Of The Buttons - Carel Datalogger Manuel D'utilisation

Important:

1. Avoid mounting the instrument in rooms with the following characteristics:
- wide and fast fluctuations of the ambient temperature;
- relative humidity exceeding 80%;
- exposure to direct water jets under pressure;
- remarkable magnetic and/or radio frequency interferences (e. g., of transmitting antennas).
2. Utilize lugs suited to the terminal block in use. Loosen each screw and insert into them the lugs, afterwards
tighten the screws. Finally, gently pull the cables to check their correct clamping.
3. Separate as much as possible the cables of the probe signals and of the digital inputs from the power and
inductive load cables in order to avoid possible electromagnetic noises. Absolutely do not introduce into the
same cable ducts (included those of the electric cables) power cables and probe cables. Avoid the probe
cables being installed close to power devices (contactors, magnetothermals, or other devices). Reduce as
much as possible the course of the probe cables in order to prevent the occurrence of spiral courses
enclosing power devices. To extend the probe cables, utilize cables with a minimum section of 0.5 mm
least.
4. Do not get near the electronic components mounted on the cards with your fingers in order to avoid stray
currents (extremely harmful) from the operator to the components themselves.
Connections:
Caution: an improper power supply connection can seriously damage the system.

Power ON
When switched on, the instrument displays an introductive mask reporting the version of the software instal-
led. After a few seconds, the instrument enters the normal functioning mode, in which the read temperature
and date are shown. At the first switching on, the operation parameters are those of default (see the table on
page 37).
Once selected, the desired values of the parameters are stored and recalled at every successive Power ON.
If at the switching on the mask:
appears, it means that the instrument has undergone damages of the hardware type (see the ALARM section).

The instrument allows the display and storage of the temperature measured with, at most, two distinct probes
(NTC). The stored temperature is the instantaneous value detected at selectable time intervals (see mask 3).
In addition to the two probe inputs, the instrument is equipped with two clean digital outputs and one exchan-
ge-relay alarm digital output. It is possible to choose whether to activate only one probe or both.
Each digital input is coupled with only one of the two probes. The keyboard consists of six buttons, four of
which are provided with back-lit LEDs.
