EXCEL CARE CONTROL ICONS ALPHABETIC REFERENCE
For load restoration, XFM 35 outputs positive values up to the value set by
parameter five every 1/10th of the interval set by parameter 10. Priority group 3
loads are restored first if they are available for restoration, followed by loads in
priority groups 2 and 1. For any priority group, Shed/Restore action is either
sequential or rotational based on the XFM parameter or the actual XFMs that are
chosen.
XFM 36-1 can provide either sequential or rotational control. XFM 36-1S provides
only sequential control and XFM 36-1R provides only rotational control.
CAUTION
Never mix sequential and rotational XFM 36s in the same group.
XFM 36-1/S/Rs St output is the start/stop (ON/OFF) signal to its load. XFM 36-
1/S/R will respond immediately to a positive or negative value into its PO input
unless one of its interval timers or the RM input prevents it.
To accomplish power demand, XFM 35 and XFM 36-1/S/R must exchange more
data than only the kW values that are transferred via the Po connections. Because
the number of XFM inputs and outputs are limited, data is exchanged via
datapoints. Datapoints are pseudo points which can be written to or read by XFM
35 and all the XFM 36-1/S/Rs in the power demand program. CARE user
addresses are assigned in special datapoint dialog boxes that are accessed from
the XFM I/O dialog boxes by clicking on the Datapoints button.
The following figure shows all the inputs and outputs of power-demand XFMs
(XFM 35, 36-1, 36-1R and 36-1S.) Datapoints are shown without any connection
lines. Note that some data points contain the priority group number (1, 2, or 3)
within the user address. In XFM 35, these are part of the preassigned XFM point
names. In XFM 36-1/S/Rs, the preassigned XFM pointnames do not contain
priority group numbers because it is not known in which group the XFM 36-1/S/R
will be located. Therefore, some XFM 36-1/S/R preassigned pointnames must be
