thermoanemometer probe.
The microprocessor control system consists of:
•
Backlight graphic display.
•

E.
Auxiliary microprocessor or redundant circuit.
Should the main microprocessor fail, the auxiliary microprocessor will activate the optical
alarm, and also the acoustic alarm intermittently. In such a case, slide the glass to the
closed position and cover the cabinet exhaust. Disconnect the equipment and contact the
Telstar Technical Service.
4.6. DISCONNECTION
To stop the cabinet, it is necessary to push the On/Off button (
Annex A3 pos. 1
) to access
the
Password Request
screen (
Chapter 4.5 point 1
). After entering the correct password,
the cabinet will disconnect.
4.7. PROLONGED STOPPAGE
In the event of a prolonged stoppage, avoid environmental dust to go inside the cabinet by
turning the cabinet off with the glass in the closed position. When it is switched on again,
proceed like the first time it was switched on. See
Chapters 3.3
and
4.1
