P9.5 - Prime pump (*DM1 PRO).
P9.5 .1
b
Prime pump enable
ID 2428
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Disabled; or
1 = Enabled.
Description:
Prime pump enable.
P9.5.2
b
Prime pump level
ID 2429
Minimum value:
0.00 varies
Maximum value:
6,000.00 varies
Default value:
0.00 varies
Description:
This defines the level at which the pre-charge function will drop out. If the feedback level raises above this value, pre-charge becomes
deactivated. If the level is not reached, it will switch after the delay time.
P9.5.3
b
Prime pump frequency
ID 2431
Minimum value:
MinFreq Hz
Maximum value:
MaxFreq Hz
Default value:
0.00 Hz
Description:
Frequency at which the pre-charge function will operate when enabled.
P9.5.4
b
Prime pump delay time
ID 2432
Minimum value:
0.00 min.
Maximum value:
3,600.00 min.
Default value:
0.00 min.
Description:
This is the time that the drive will run the pre-charge function on start up. When set to "0 Hz", this function is not enabled.
P9.5.5
b
Prime pump loss of prime level
ID 2433
Minimum value:
0.00 varies
Maximum value:
1,000.00 varies
Default value:
0.00 varies
Description:
Selects the limit to indicate a loss of prime in pump. If the measured current drops below the determined value for the value assigned in
the prime loss of time setting, the drive will display "pre-charge loss of prime".
P9.5.6
b
Prime pump level 2
ID 2434
Minimum value:
0.00 varies
Maximum value:
6,000.00 varies
Default value:
0.00 varies
Description:
This defines the level at which the pre-charge function will drop out. If the feedback level raises above this value, pre-charge becomes
deactivated. If the level is not reached, it will switch after the delay time.
P9.5.7
b
Prime pump frequency 2
ID 2436
Minimum value:
MinFreq Hz
Maximum value:
MaxFreq Hz
Default value:
0.00 Hz
Description:
Frequency at which the pre-charge level 2 will operate at when enabled.
P9.5.8
b
Prime pump delay time 2
ID 2437
Minimum value:
0.00 s
Maximum value:
3,600.00 s
Default value:
0.00 s
Description:
This is the time that the drive will run at the 2nd level pre-charge function level. When set to "0 Hz", this function is not enabled.
P9.5.9
b
Prime pump loss of prime level 2
ID 2438
Minimum value:
0.00 varies
Maximum value:
1,600.00 varies
Default value:
0.00 varies
Description:
Selects the limit to indicate a loss of prime in pump. If the measured current drops below the determined value for the value assigned in
the prime loss of time setting, the drive will display pre-charge loss of prime.
P9.6 - Broken pipe (*DM1 PRO).
P9.6.1
ab
Broken pipe fault response
ID 1853
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = No action;
1 = Warning;
2 = Fault, coast; or
3 = Fault.
Description:
Broken pipe fault/warning shall betriggered if the PI feedback is less than broken pipe level and the drive output frequency is more than
broke pipe frequency for delay time.
P9.6.2
b
Broken pipe level
ID 1854
Minimum value:
0.00 varies
Maximum value:
6,000.00 varies
Default value:
15 varies
Description:
Broken pipe level.
