The rotational mode switches an XFM 36-1/R load independent of its rank in the
group (Parameter P14 [Load Number]). Each XFM 36-1/R in a group counts the
duration (in seconds) of its ON status and stores it in Parameter P8. It stores its
OFF status in Parameter 9.The maximum value of all P8s in a priority group is
stored in user address IA___On_Index_P1/2/3. The maximum value of all P9s is
stored in IA___Off_Index_P1/2/3. The next load that can switch on is the XFM 36-
1/R that has the greatest Switch Off Index (P9) value and the next one that can
switch off is the XFM 36-1/R that has the greatest Switch On Index (P8) value in
the group.
The criteria for rotational switching ON a load are as follows:
• The XFM 36-1/R is in automatic operating mode (Parameter P13 = 0).
• Parameter P15/16/17 in XFM 35 is 0 and user address ID___Rotating_P1/2/3 is
1. (ID___Rotating_P1/2/3 is not required for XFM 36-1R.)
• The power value at the first input Po is positive and equal or greater than the load
power Parameter P15 of the XFM 36-1/R.
• The value of the user address IA___Off_Index_P1/2/3 is less than or equal to the
XFM 36-1/R switch-off index Parameter P9 (for example, XFM 36-1/R is in the
third priority group; the value of IA___Off_Index_P3 is 105600; and the switch-off
index Parameter P9 has the same value 105600).
• The minimum OFF time (Parameter P11 of the XFM 36-1/R) has expired.
• If Parameter P16 of the XFM 36-1 is 1, input RM must also be 1 (see the RM
Functions description later in this section for details).
• User addresses ID___Peak_load and ID___Shutdown are 0 (that is, the peak
load and shutdown functions are not active).
The criteria for rotational switching OFF a load are as follows:
• The XFM 36-1/R is in automatic operating mode (Parameter P13 = 0).
• Parameter P15/16/17 in XFM 35 is 0 and user address ID___Rotating_P1/2/3 is
1.(ID___Rotating_P1/2/3 is not required for XFM 36-1R.)
• The power value at the first input Po is negative.
• The value of the user address IA___On_Index_P1/2/3 is less than or equal to the
XFM 36-1/R switch-on index Parameter P8 (for example, XFM 36-1/R is in the
second priority group; the value of IA___On_Index_P2 is 145265, and the switch-
on index Parameter P8 has the same value 145265).
• The minimum ON time (Parameter P10 of the XFM 36-1/R) has expired.
