5. Installation
Important!
The connection of an alarm to the plug provided must be
carried out by trained personnel if the voltages are greater
than 33 V AC or 70 V DC.
The external alarm is triggered, when the chamber temperature exceeds
the selected value.
When the temperature dips back down below the defined threshold, the
external alarm is immediately switched off.
Loss of mains power supply (instrument switched off or power failure) will
also trigger the external alarm.
On return of mains supply the alarm is automatically switched off.
The instrument has a socket via which an external alarm can
be output (see Fig. on p. 29 and wiring diagram). The maxi-
mum permitted voltage that can be switched is 250 V.
Because a compatible plug is provided with the instrument,
the user must make a corresponding connection onsite.
