6-6. Switch-Over Relay
a. Switch-Over Relay in OFF Position
The Switch-Over Relay supplies the 24 volt input
power from either the BATTERY or AC120V oper-
ating modes to the relay box for table operation. In
the normal OFF position, BATTERY power is sup-
plied to the relay box. See figure 6-9.
Figure 6-9. Relay in OFF Position
b. Switch-Over Relay in Activated Position
When the AC120V mode is activated by the main
switch, a signal from the relay box activates the
Switch-Over Relay. The relay then supplies the
AC operating mode output power to the relay box
and also activates the battery charging circuit. See
figure 6-10.
NOTE
The battery charging circuit is only op-
erational when the table is in the
AC120V operating mode.

The Switch-Over Relay mounting block
may have to be removed from the base
for test access.
