Response from
No Flow situation
PAUSE
FAULT
PAUSE
It allows selecting the drive response from No Flow detection
situation.
OPT
FUNCTION
PAUSE
It will generate the stopping of the drive, and next,
the fixed pumps. ‘NO FLOW’ will be visualized.
Once the no flow condition disappears, if the
delay time after pause has elapsed, the drive will
start.
FAULT
It will cause a fault and next, the fixed pumps will
be stopped. In this case, ‘F69 FLOW SWITCH’
will be visualized.
YES
16 NO FLO/FILL=N
G25.6.16

process
N
Y
N
It allows enabling or disabling No Flow switch to stop the drive
during pipe filling process, according to the mode selected in
G25.6.14 (PAUSE or FAULT).
OPT
FUNCTION
N=NO
The drive will ignore No Flow input during pipe
filling process.
Y=YES
The drive considers No Flow input during pipe
filling process to stop.
YES
17 NO FLsp=+0.0%
NO FLOW MIN SPED
G25.6.17
/
Minimum stop
speed because
of No Flow
detection
+0.0 to
+250%
+0.0%
Setting of a minimum stop speed of the drive when No Flow
situation is detected. When the motor speed is higher than the level
set here, the No Flow switch can generate a stopping by PAUSE or
by FAULT, if the other conditions above mentioned are fulfilled. On
the other hand, when the drive speed is lower than the level set
here, the No Flow switch can generate that the drive goes to sleep,
whenever the other needed conditions to activate the sleep mode
are met. Therefore, when the drive speed is lower than the level set
here, the equipment will check the setting of the parameter
‘G25.4.10 FLsw ENA ’. If the setting is YES, then the equipment will
sleep if the other conditions are met.
YES
18 NO FLbyp=0.0s
NO FLO BYPAS DLY
G25.6.18
/
Bypass time for
No Flow switch
0.0 to 999s
0.0s
During this time the No Flow input is ignored.
This time has only sense elapsed from the starting of the drive,
whenever the pipe filling process is not activated.
If the filling option is activated, then the SD700 will check the setting
of the parameter ‘G25.6.16 NO FLO/FILL’ before.
If this parameter is set to YES, then No Flow option is active during
the pipe filling process. In this case, the bypass time will be counted
although pipe filling process is active.
On the other hand, if this parameter is set to NO, the No Flow option
is not activated during the pipe filling process. In this case, the
bypass time will start elapsing after pipe filling process finishes.
YES
19 NO FLdly=0.0s
NO FLOW FLT DLY
G25.6.19
/ Trip
delay time
because of No
Flow
0.0 to 999s
0.0s
It sets the delay time from the No Flow switch is opened to the drive
stops. In case of the bypass delay time is also configured, both
delay times will be considered.
YES
20 CYCLE TI=0m
CYCLE RESET DELY
G25.6.20
/ Cycle
time of the drive
OFF=0 to
999m
0m
Setting of the time that must elapse from the SD700 stops to starts
again, for the cycle counter G25.6.21 is reset.
This function is a protection from situations where keeping the
pressure level is difficult for the drive and, for example, the drive
goes to sleep and wakes up immediately (a faulty check valve,
incorrect setting of the parameters or problems with measurement
sensor). This function also will operate together with cavitation
protection avoiding that the drive pump is starting and stopping
continuously in cavitation pauses.
If the drive starts a number of times without relaxing for the time set
here, then it will trip by ‘F71 CYCLING’, also stopping the fixed
pumps.
YES
21 CYCLE CNT=5
MAX CYCLES ALLOW
G25.6.21
/ Cycle
counter
OFF, 1 to 5
5
Setting of the maximum allowed cycles without relaxing. If this
number is exceeded, trip will be generated.
Note
: Go to sleep and wake up is also considered a cycle.
YES
