7465 Sync Changeover Switch and 9465 3G Sync Changeover Switch
Because both the NO and NC connections are provided, it is possible to have independent status lines
for each of the two states of a status signal. For example, if the jumper is set to +5V, the Primary NO
output will source +5V when the relay is in the normal position (Signal Failed) and the Primary NC
output will source the +5V when the relay is closed (Signal Good). Additionally, in the case of selecting
+5V as the common, the 1k Ω resistor on the module will act as a current limiter, allowing the direct
connection of ordinary LEDs to each of these output pins. A green LED could be connected to the NC
output and a red LED to the NO output. This would provide very complete and explicit indications to
the operator as to the signal status.
Also available through the Control connector are two Override GPI inputs that when closed to ground,
will force the switch to either Primary or Secondary. These inputs may also be used to reset the Primary
after a fault has cleared.
Module Configuration and Control
The configuration parameters for each Avenue module must be selected after installation. This can
be done remotely using one of the Avenue remote control options or locally using the module front
panel controls. Each module has a REMOTE/LOCAL switch on the front edge of the circuit board
which must first be set to the desired control mode.
The configuration parameter choices for the module will differ between Remote and Local modes.
In Remote mode, the choices are made through software and more selections are available. The
7465 and 9465 Parameter Table on the following page summarizes and compares the various
configuration parameters that can be set remotely or locally and the default/factory settings.
If you are not using a remote control option, the module parameters must be configured from the
front panel switches. Parameters that have no front panel control will be set to a default value. The
Local switches are illustrated in the Front Panel Controls and Indicators section following the 7465
and 9465 Parameter Table.
Avenue module parameters can be configured and controlled remotely from one or both of the
remote control options, the Avenue Touch Screen or the Avenue PC Application. Once the module
parameters have been set remotely, the information is stored on the module. This allows the module
be moved to a different cell in the frame at your discretion without losing the stored information.
Remote configuration will override whatever the switch settings are on the front edge of the module.
For setting the parameters remotely using the Avenue PC or Avenue Touch Screen option, refer to the
Avenue PC and Avenue Touch Screen Remote Configuration section of this document.
