3.5 Area switching
A maximum of 32 sets of area can be configured in SE2L. However the maximum configurable area
number differs depending on the selected function such as, muting and dual protection. Table 3-1 shows the
maximum configurable area number according to the used mode.
External input signals are provided in SE2L for switching the area. Each signal has a pair of normal and
inverted signal. For example, it is necessary to provide both input signal IN_A and inverse IN_A signal to
switch the area. Error will occur if IN_A and inverse IN_A signals do not complement each other. Table 3-2
below shows the combination of input signal to switch the area. Area in use will be displayed in the 7
segment LED of SE2L.
It is also possible to configure area input delay. Configure the necessary delay required for the system to
provide stable input signals to SE2L. The default value is 30ms.
There are maximum 5 input pairs (a pair is combination of normal and inverted signal) in SE2L therefore,
it can operate with maximum 32 sets of area. Further, it is also possible to switch the area through the speed
monitoring of increment encoder signal connected to SE2L
(

*1: Muting function and dual protection mode cannot be used if encoder input mode is selected.
*2: Among the 4 input patterns, at least one pattern must be used for encoder input. Other 3 remaining
patterns can be selected to be used as static input or not in use. A pattern with encoder input mode can
have maximum 32 sets of area (for detail, refer to section 3.6.4).
