LED INDICATORS
Three LED indicators allow visual indication of operation of the RY7, RY8 and AC1 relays.
RY7 (Yellow) LED
Allows visual indication of relay RY7 operation. During the automatic generator control sequence, the
LED will be on to show that RY7 is closed (engaged) from the N.O. to the COM contacts, and will be
off when RY7 is opened (disengaged).
RY8 (Green) LED
Allows visual indication of relay RY8 operation. During the automatic generator control sequence, the
LED will be on to show that RY8 is closed (engaged) from the N.O. to the COM contacts, and will be
off when RY8 is opened (disengaged).
AC1 RELAY (Red) LED
Allows visual indication of AC1 relay operation. The LED will be on when the AC1 relay is closed
(engaged). This LED along with the test-jumper adjacent to the LED is used by utilities to perform
voltage and frequency tests to qualify the SW Series Inverter/Charger for line-tie applications.
BTS PORT
The battery temperature sensor (BTS) can be connected (plugged in) at the RJ-11 four-conductor
connector, located on the AC Circuit Board. The BTS provides information that enables the three-stage
standby battery charger to "fine tune" the battery charge voltages for better charging performance, greater
efficiency and longer battery life.
AC TERMINAL BLOCK
A six position terminal block is provided to make the AC connections. The terminal block is located on the
AC Circuit Board. The terminal block is used to hardwire all AC input and output connections.
