Input Signals
The Talos Bill Acceptor is controlled by the Control System via the following four pairs of
input signals.
Denomination
1 ENABLE, denomination 2 ENABLE, and denomination 3 ENABLE (High or Low) are three
independent, optically isolated input pairs allowing either sink or source enable control for
three different bill types. These input pairs are activated by the application of 5VDC1 to
ENABLE (High) and GROUND1 to ENABLE (Low). Note that either the High or Low input
can be connected directly to its appropriate level while the other input becomes the switched
input for controlling the enable function.
Deactivation of any of the signals prevents the appropriate bill from being accepted;
however, the control board must provide for a one second timing window after deactivation
to allow a bill already in process to be accepted.
Denomination 1 ENABLE, denomination 2 ENABLE, and denomination 3 ENABLE are also
used to allow user escrow. The appropriate ENABLE signal
must be disabled according to the timing diagram following acceptance of a bill to keep that
bill in the escrow position pending further instruction of the ESCROW signal. Reactivation of
the ENABLE signal without deactivation of the ESCROW signal will credit the bill.
Escrow
(High or Low) is an optically isolated input pair allowing either sink or source escrow control.
This input pair is activated by the application of 5VDC2 to ESCROW (High) and GROUND1
to ESCROW (Low). Note that either the High or Low input can be connected directly to its
appropriate level while the other input becomes the switched input for controlling the escrow
function.
Not activating the ESCROW signal will prevent a bill from being held in the escrow position.
