monitor system:
• 0: 3 probes without control of the cooling fans.
• 1: 4 probes with control of the cooling fans.
• 2: 4 probes without control of the cooling fans.
• 3: 3 probes with control of the cooling fans.
Modify it pressing buttons UP/DOWN and confirm by ENTER.
Default configurations: P=140, A=160, L=90, H=100, F=0.
Soon out of programming procedure the device executes a LAMP TEST.
System is prearranged in automatic way and visualises so the maximum measured
temperature and the relative channel.
Anyway, the necessary time for programming is checked. Over 1 minute from
beginning of the programming phase, the same is interrupted and is not saved so
the previous set limits remain active.
The visualisation mode can be modified from manual to automatic system pressing
the special button AUTO/MANUAL.
During automatic working the higher temperature and the relative number of
channels appear on the display.
In this mode is possible to read all the parameters of the device. Pushing buttons
UP/DOWN is possible to show in order:
letter P (pre-alarm), letter A (alarm), letters L and H
(fan threshold), letter F and the current values in the four channels. After approx.
two seconds from the last showing, the device comes back to the normal working
condition.
In manual mode, unlike the automatic working, it's possible to visualise for an
indeterminate period of time one of the 4 channels or any other programming
parameter.
The monitoring of the other channels and the eventual state of pre-alarm, alarm or
failure which have been created are also guaranteed during manual working.
For security reasons, after a minute of inactivity by the operator, the control unit
returns to automatic display mode.
For the visualisation of the maximum values of the machine push the buttons
AUTO/MANUAL and ENTER/TEST at the same time. The visualisation of the
maximum temperatures is signalised through the led T. MAX which is placed on
the front-end panel.
Please note that the maximum values are reset every time you enter in the
programming phase.
The state of fan relay when the system is in mode 1 or 3 is signalised by the led
