• AC/TAPS DISCONNECT switch: In the OFF position, this switch removes all power
from the elevator system by opening up contactor
KM0
, even in the presence of commer-
cial power. The switch also insures that contactor
KM5
will not close in the event of com-
mercial power loss. This switch possesses an integral lockout design with provisions for
three different lockout tags/padlocks only while in the OFF position for code and safety
compliance. In the OFF mode, power to the logic board is also disconnected. In the ON
position, power will be provided through normal commercial power (AC mains) to the ele-
vator controller via contactor
KM0
or through contactor
KM5
when in backup mode.
• TAPS/BYPASS switch (must remove top cover to access): In Bypass position, the TAPS
backup power source is prevented from providing power to the TAPS outputs regardless of
commercial power presence or absence. Feed through power from commercial AC remains
connected to TAPS outputs. In Normal position, feed through power from AC mains is
connected and, should commercial AC fail, the TAPS logic board will direct backup power
to terminals L1X and L2X. There is an internally timed delay between Bypass selection and
activation, typically two seconds.
• Test button: When the test button is pressed, TAPS will disconnect commercial power to
the controller, provide power to complete a recall/rescue cycle, and finally detect commer-
cial power presence and return the car to normal operation.
Note
You must press and hold the Test button until the time set by Parameter F1-9 elapses before the
test will begin. (Factory default setting is 2.0 seconds.)
