CHAPTER OBJECTIVES
Chapter 8 describes the programming procedure for the SMP-3
overload relay. The Logic Mask is the only SMP-3
programmable parameter.
LOGIC MASK PARAMETER
The Logic Mask parameter can be used to mask (disable) or
unmask (enable) either an HIM or communication module.
When an adapter is masked, its control functionality over the
SMP-3 is disabled. Conversely, when an adapter is not masked,
its control functionality over the SMP-3 is completely enabled.
Each bit in the Logic Mask parameter represents a port
address. Since the SMP-3 overload relay only supports Port # 1
and #2, only bits 1 and 2 of the Logic Mask are used, as shown
in Figure 8.1:

Note: The adapter connected to Port #1 is considered adapter
1, while the adapter connected to port #2 is considered adapter
2.
When a Logic Mask bit is set to “1,” the adapter connected to
the respective port is enabled.
00000X10 – Port ID #1 is enabled
000001X0 – Port ID #2 is enabled
00000110 – Port ID #1 and #2 are enabled
