ALARM SOUNDS
There are two di erent alarm sounds. If both are simultaneously activated, they ring out after one
another at an interval of approx. 6 seconds.
Tone sequence 1: short – short – long
Tone sequence 2: long – short – long – short
6. VENTILATION ADJUSTMENT • MONITORING
The ventilator capacity is su cient for a minimum ten-fold change of air for those cabinet models
listed under the „Purpose" item. The faultless ventilation function is automatically controlled by a
monitoring electronics system. A di erential pressure measurement device monitors air volu-
mes in the extraction air shaft. An alarm is triggered (C3) when the air rated value is undercut by
around 50 %. The optical alarm only stops when the rated value is again attained.

7. POTENTIAL FREE ALARM CONTACT

In order to use the potential-free alarm contact, the supplied three-pin plug must be used. Only the two outer
terminals are connected to the plug! The contact is designed for a maximum DC voltage of 30 V DC or an
AC voltage of 230 V AC. The maximum current load is 10 A. The switch contact is closed when de-
energized! As soon as mains voltage is applied and there is no malfunction (device "ready for operation"),
the switch is open.
REASON – ACTION
extraction air opening (to be removed) or
ventilator.
Internal
alarm contact
CAUTION:
The potential-free alarm contact must not be used to switch large loads. It is only intended for a mal-
function of the air circulation filter attachment by a signal light, horn or similar. to signal.
The connection must be carried out by a qualified electrician!
NOTES - must be observed!
The C13 cable must be removed before replacing the fuses
