< 1 to 5V input and 4 to 20mA input of power amplifire >
When the power amplifire is operated under " 0 to 5V input mode " (DIP SW1 to SW3= ON), it is possible
to change the mode to "1 to 5V input mode " by performing the following operation.
When using the power amplifire under " 4 to 20 mA mode ", connect a precision resistor ( 250Ω, 1W )
across the terminals SP and SN, and use it as " 1 to 5V input mode".

< 1 to 5V input and 4 to 20mA input of power amplifire >
It is possible to change the terminals S1-S2 ( aux. power output ) of the LE-50PAU from the aux. power
output mode to the [ RUN ] output mode by performing the following operations.
[ RUN ] output means that 12VDC ( load current : 100mA or less ) is output while the LE-50PAU is op-
erating properly.
When any wire deiconnection or short-curcuit occurs in the cluctch / brake for one second or over, which
is connected across the terminals PP and PN, the output is turned off ( 0V ).
When the terminals S1-S2 are used under [ RUN ] output mode, the remote input SC of aux. power
source is invalidaded, and the timer setting value ( SST ) of aux. power source is also invalidated.
