AL_S02 LP pressure switch LP switch out of order or
out of order or tripped
disconnected pressure switch open and
LP > LP_PreAlrm_Thrsh
(0.5 bar)
This is not a triggering of
LP due to an empty circuit
AL_S03 LP alarm Software triggering of LP
Software triggering threshold overshooting
LP < LP_Alrm_Thrsh (0.5
bar)
AL_S04 Trig. LP pressure Triggering of the LP switch
switch upon overshooting of
Low pressure pressure threshold (normal
triggering of pressure
switch)
AL_S05 LP default alarm LP fault alarm
Pressure too low LP switch closed and
LP < LP_Alrm_Thrsh (-0.5
bar)
Under pressure without
tripping pressure switch
AL_S06 HP pressure switch HP pressure switch out of
out of order or order or disconnected
disconnected Open HP switch and
HP < HP_PreAlrm_Thrsh
(21.0 bar)
This is not a triggering of
HP due to overpressure
AL_S07 HP alarm Software triggering of HP
Software triggering threshold overshoot
HP > HP_Alrm_Thrsh (21.6
bar)
AL_S08 Trig. HP switch Triggering of the HP switch
High pressure upon overshooting of
pressure threshold (normal
triggering of the pressure
switch)
AL_S09 HP fault alarm HP fault alarm
Pressure too high HP switch closed and
