Power Demand Control XFMs
Function The power demand control functions measure the energy consumption of the plant
electrical units. They then calculate current power consumption, compare it to a
power limit, and decide which loads to switch on or off.
Power demand control consists of four XFMs: XFM 35, XFM 36-1, XFM 36-1S and
XMF 36-1R. Many load switching behaviors are available because multiple XFM 36-
1, XFM 35-1S and XFM 36-IRs with various parameter settings can connect to a
single XFM 35.
XFM 35 is the strategy program. It takes in the totalizer point values, applies them to
the chosen algorithm, and outputs control signals to the XFM 36-1/S/R single-stage
load programs in each of up to three priority groups. Each priority group can contain
up to 50 single-stage load programs (XFM 36-1/S/Rs) connected in a loop.
NOTE: Although 50 XFM 36-1/S/Rs are allowed, controller cycle time will be long
with large numbers of XFM 36-1s. Use the smaller XFM 36-1R or XFM 36-
1S to use less controller memory and cycle time. A total of 127 XFMs are
allowed in a controller.
