• The XFM 36-1/S is in automatic operating mode (Parameter P13 = 0).
• Parameter P15/16/17 in XFM 35 is 0 and the corresponding user address
ID___Rotating_P1/2/3 is 0.(ID___Rotating_P1/P2/P3 is not required for groups
with XFM 361S.)
• The power value at the first input Po of the XFM 36-1/S is negative.
• The value of the user address IA___On_Index_P1/2/3 is equal to the XFM 36-1/S
load number set in P14 (for example, XFM 36-1/S is in the second priority group;
the value of IA___On_Index_P2 is 7; and the load number Parameter P14 is 7).
• The minimum ON time (Parameter P10 of the XFM 36-1/S) has expired.
The following table lists the parameters used for sequential switching:
Type Description
Comm. Minimum ON Time
Comm. Minimum OFF Time
Comm. Mode of Operation
0=Auto
1=ON
2=OFF
Progr. Load Number (Priority Rank within a Group)
(highest number is shed first)
Progr. Power of the Load
Progr. Feedback_Op_Mode
In rotational mode, each load in a priority group is switched ON or OFF depending
on the amount of time the load has been OFF or ON, respectively. The load that has
been OFF the longest is turned ON first. The load that has been ON the longest is
turned OFF first. Excluding the effects of the Maximum Off Time function, the RM
input and manual override on the loads, shed and restore action resembles true
rotational or circular action as pictured below.
You select the rotational mode of load switching in each priority group by setting
Parameters P15 (for Group 1), P16 (for Group 2) and P17 (for Group 3) in XFM 35
to one. XFM 35 passes these parameters to each XFM 36-1 via the corresponding
user addresses ID___Rotating_P1, ID___Rotating_P2, and ID___Rotating_P3. The
user address is not required if only XFM 36-1R is used in the priority group.
