P8-12
Bypass Mode on Fire
0
1
0
-
Parameter configures the drive to switch to bypass mode automatically should an input to the drive be configured for Fire Mode
operation and that input becomes active. When enabled the drive standard relays 1 and 2 are dedicated to bypass control and
cannot be assigned other functions.
0 = Disabled
1 = Enabled
P8-13
Bypass Contactor Changeover Time
0
30
2
s
Parameter active when Bypass function is enabled. Parameter P8-05 sets a time delay or changeover time between the switching
of the drive relays controlling the bypass circuitry.
Care must be taken when setting P8-13 to ensure that drive and DOL contactors are not switched in circuit simultaneously.
Both Mechanical and Electrical interlocking of drive and DOL contactors to regional standards are recommended in configuring
the Bypass function
P8-14
Pump Staging Function Select
0
4
0
-
Parameter enables the pump staging (cascade) function on the drive
0 : Disabled
1 : Single VFD with DOL Cascade (max 4 DOL pumps)
2 : Multiple Drive Cascade (Optiflow) Master Drive (Only valid when drive set to Optibus master address, P5-01 = 1)
3 : Multiple Drive Cascade with Jockey Pump (Optiflow) Master Drive (Only valid when drive set to Optibus master address, P5-
01 = 1) In this instance, the Master drive (with address P5-01 =1) will remain active and will not be switched off to support the
pump rotation ordinarily used for the purpose of sharing operating hours across all pumps.
4 : Multiple Drive Cascade Mode 2 (Optiflow) Master Drive (Only valid when drive set to Optibus master address, P5-01 = 1) This
mode is similar to mode 2 but the settling time works differently which can prevent multiple motors starting simultaneously when
waking up from PID Standby mode
P8-15
Number of Assist Pumps
1
4
1
-
Parameter valid when P8-14 is set to 1 or 2 to enable Pump Staging Function. P8-15 set the number of assist pumps (P8-14 = 1) or
network slave drives (P8-14 = 2) that are available in the Pump Staging application. Setting the value to 0 disables Pump Staging.
P8-16
Pump Duty Switch Over Time
0
1000
0
Hours
In order to balance run time (duty) on each pump in the Pump staging application and to ensure periodic operation of each pump P8-
16 can be set with a time limit for pump switch over. When set to a value other than 0 (disabled) the operation of each staging pump
will be cycled to ensure the difference in duty between each pump does not exceed the time set in P8-16
P8-17
Assist Pump Start Speed
P8-18
P1-01
49.0
Hz / RPM
This parameter defines the speed at which an “Assist” Pump is started when using the Pump Cascade or Optiflow feature. When the
drive output increases beyond this threshold the next Staging pump is switch on. The Pump staging settle time must then expire
before additional staging pumps can be brought on or off line. Priority for Staging pump switch on is always given to the pump with
lowest run time accumulated.
P8-18
Assist Pump Stop Speed
0
P8-17
30.0
Hz / RPM
This parameter defines the speed at which an “Assist” Pump is stopped when using the Pump Cascade or Optiflow feature. When the
drive output decreases below this threshold one of the Staging pumps currently operating is switch off. The Pump staging settle time
must then expire before additional staging pumps can be brought on or off line. Priority for Staging pump switch off is always given to
the pump with highest run time accumulated.
P8-19
Pump Settling Time
2
600
60
Secs
Parameter sets a time delay for pump staging whereby, following switch in or switch out of a staging pump, further pumps are not
permitted to be switched in or out until this time period has elapsed. This parameter should be set to allow adequate settle time
between staging pump transitions.
P8-20
Pump Master Clock Reset
0
1
0
-
Master drive in pump staging monitors and maintains duty run times for all available staging pumps. All clocks are available to view in
P0-20. P8-20 provides the master reset to all run time clocks used for Pump Staging Function (all clocks set to 0).
