TECHNICAL INFORMATION
99/107 87-901-011-01
between the ProfiBus network and the pump’s
controller serial interface. As a consequence of
this, the scale and the meaning of some parame- ters depends directly to the specific model of
Turbo Pump controller connected to the interface.

0 = inf.
Vent Valve Opening Delay
Set the delay time between the stop command and vent opening.
Valid only in “purge/vent auto mode” (Parameter Buffer byte-15 B1=0); de-
fault = 15; 0 = infinite (the valve will never open)
126

Vent Valve Open Time
Set how long the vent will remain open, then both purge and vent will be
closed. Valid only in “purge/vent auto mode” (Parameter Buffer byte-15
B1=0); 0 = infinite (the valve remain open till a start command)
147
B0 - Vent & Purge Controlled Vent Procedure/Man
0 = Controlled Vent Procedure
1 = Manual (see Par. Buff. byte-15-B1)
125
B1 - Vent & Purge Remote/Profibus
0 = serial or Profibus (see Out. Buff. byte-0 B3 and B2)
1 = remote ( the valves are driven by the inputs on remote I/O connector)
146
B2 - Interlock Type
0 = continuos (the interlock must be present to run the pump)
1 = at start (the interlock must be present only at start command)
