Ventilation
Usually the parts under test are vented with ambient air after the test has been
finished. If it is required, the parts can be vented with an different gas type (i. e. fresh
air, dry air, nitrogen, …) at a pressure of max. 1050 mbar. In these cases, the gas
supply has to be connected to flood connection (8 mm hose connection) on the left
side of the device. The gas pressure on the flood connection may not exceed
1100 mbar (absolute).
It is also possible to connect an additional external ventilating valve to the valve
output V21.
Sniffer line
The connection for the sniffer line exists only for the sniffer version of the Modul1000
(catalogue number 550-310). This connection is for the optional sniffer line SL200.
The SL200 is connected to the power system via the connector socket ACCESSO-
RIES.
