2. Fault or Stop
When the running D2D Master(Lead) is stopped manually or faults offline, the transfer of the D2D
Master status will immediately switch to the next “Available” D2D Follower (Lag pump). It will always
follow the sequence ring of 1-2-3-4-5-6 and not follow the accrued hours run time.
3. Sleep Cycles
Based on the number of times the D2D Master (Lead) drive has completed the “Sleep” function. This
would need to be configured with the Wizard or with Parameter 81.36, “SWITCH LEAD SLP COUNT”.
The transfer of the D2D Master (Lead) status to the next “Available” D2D Follower (Lag pump) with
lowest run time when the switch needs to occur. See Notes 1& 2 above.
4. Manual Switch
On the Running D2D Master (Lead) drive you can access Parameter 81.32 and switch the Master Sta-
tus to any “Available” pump. If not “Available” the switch selection will not function. See the Screen
shot below:
The Following table identifies the parameters used in Lead Lag Switching:
81.23 MULTIPUMP RUNTIME RESET Selecting Reset clears the operating hours accumulated on this drive only when running in
MultiPump operation.
81.31 SWITCH LEAD TIME Defines the elapsed actual motor runtime time the D2D Master (Lead) will run before
switching to the next available D2D Follower (lag) in the system. 0.00 hours disables the
function, including alternating when a fault may occur. For the equivalent of disabling the
alternating function and allowing for alternation during a fault, set the value to 99999.00
Setting range is .01 to 99999.00 hours. Maximum hours =11.5 years.
81.32 SWITCH LEAD Allows for the manual switching of the D2D Master (Lead) via this parameter. Selections are:
Disabled (default), pump 1, pump 2, pump 3, pump 4, pump 5 and pump 6. This parameter
returns to disabled after a selection is made. Manual switch shall function only through the
D2D Master using the D2D Master’s keypad, or PC tool.
81.36 SWITCH LEAD SLP COUNT
Defines the elapsed number of times the D2D Master (Lead) pump goes into sleep mode.
After this count the DS2D Master (Lead) will be automatically transferred to the next available
D2D Follower (Lag) in the sequence. Any value greater than 0 automatically sets parameter
81.31 to 0 disabling switching based on hours.
81.41 Follower Switch Factor This allows for the automatic balancing of D2D Follower (lag) pumps if used on a system with
significantly unequal run times. It will use this number as a multiplier of the switch hours to
offset the unequal time differences to eventually equal them out over time. The default is 0
1.238 MULTIPUMP RUNTIME Provides the length of time this drive pump has run in Multipump. Does not include
sleeping. 0 – 65535.Hours and is viewable only
