No. Designation min. max. Default Unit r/w Format Description
183 Max. passing time 0 P32 500 s r u16 Maximum permissible time during which
the pump with the start signal present must
have passed the critical speed range
between 60 Hz and P20.
184 Converter operation hours 0 Sums the operating hours of the converter
2147483647 0 0.01 h r u32 during active pump operation.
199 Converter factory date 0 20991231 0 r u32 Converter date of manufacture
(YYYYMMDD).
227 Warning bits 1 0 65535 0 r u16 Active warning, bit-wise representation:
Bit 3 = Pump temperature warning (P127 > P128)
Bit 11 = Overload warning (P3 < P25*P24
after normal operation has been attained,
not evaluated during generator operation)
Bit 14 = Power supply voltage warning
(P4 > Umax or P4 < Umin or mains power
failure)
237 Function normal operation 0 3 2 R/W u16 0 = Off
relay on 25-way 1 = On
PLC interface 2 = Normal operation
3 = Heating (active at normal operation
and High signal at digital input 1)
239 Function optional relay 1 0 2 2 R/W u16 0 = Off
1 = On
2 = Acceleration (corresponds to bit 4
in the status word)
240 Function optional relay 2 0 5 4 R/W u16 0 = Off
1 = On
2 = Pump is turning (corresponds to bit 11
in the status word)
3 = Converter is active (corresponds to bit 2
in the status word)
4 = Valve and forevacuum
(active for driven pump)
5 = Power failure venting (active at frequency
above P247
243 Time delay SEMI F47 0 6000 500 0.01 s r/w u16 Adjustable time which in the case of an
AC voltage breakdown is bridged without
an error message. For the entire duration,
the converter will indicate a normal operation.
Auxiliary parameter for fulfilling SEMI F47
requirements.
247 Power failure P248 P18 300 Hz R/W u16 Frequency at which the venting valve shall
“vent on” frequency be switched on in case of a mains power failure.
Power failure venting can be enabled
through P240.
248 Power failure 0 P247 5 Hz R/W u16 Frequency at which the venting valve shall
“vent off” frequency be switched off in case of a mains power failure.
Power failure venting can be enabled
through P240.
254 RS 485 address 0 31 0 R/W u16 Currently valid address at the bus adapter.
