4.4 Connection of output circuit
The one-reel controller or feeld roll controller does not use any aux.power amplifire.
Set the DIP switch SW4 to SW10 in accordance with the rated current of clutch / brake connected to the
LE-50PAU power amplifire output [PP] - [PN]. ( See page 5. )

• The reel change circuit is as shown above.
Prepare a switch which is turned on wihle the old reel is stopped, and connect it to across the terminals
[SC] and [SN].
• Do not short circut across the terminals [PN] and [S2], for current control of power amplifire and for
detection of over-current.
For this reason, use a bipolar ( negative / positive ) switching curcuit.
• Be sure to connect a sires resistor ( RA, RB ) to the commutation diode ( DA, DB ) used for protection
of changeover swich, by which the normal commutation current flows in the diode built in the power
amplifire, which allows the current to be detected correctly.
