1. Stufe 2. Stufe 3. Stufe Description, Explanation
• Internal nozzle diameter [mm]:
•
Minimum pressure while pre-purging [mbar]: During pre-
purging procedure the PS840 monitors a increased pressure
inside of the Ex pzc-housing to achieve the defined flow on
the output valve. This increased pressure is monitored with
this parameter (range = 7.0 mbar ... max. pressure)
Minimum pressure at normal operation [mbar]:
Monitored minimum pressure
Maximum pressure at normal operation [mbar]:
Monitored maximum pressure
Signal pressure at normal operation [mbar]:
Menu code: Code word to start the main menu.
Ex works: “0001”
It is not possible to deactivate this code with „0000“.
Bypass code: Code word to start bypass mode.
The code can be disabled with „0000“ . The sequence „9999“
disables the bypass in general
