LED Indicators
The green LED indicator on the front panel marked
POWER will be illuminated when the unit is
powered-up.
The LED marked ACTIVE will be illuminated when
the front panel is connected to and communicating
with a unit.
The LED marked ERROR will flash to indicate that
errors have occurred.
Note that if an attempt is made to access data that
does not exist, this will be recognised as an
ERROR.
If the HELP button indicator is also flashing
pressing this button will display a list of the errors in
the control window.
Pressing the button adjacent to the error message
will clear the error message if the error no longer
exists.
Note that the ERROR LED will also continue to
flash steadily until all the error messages have
been cleared.
The ERROR LED will also flash momentarily during
a RollNet reconnect. If this LED lights up
continuously, or flashes intermittently, the network
is unstable. This would indicate broken cabling,
missing termination etc.
Dedicated Push Buttons
Various specific operations may be carried out by
using these push buttons.
When pressed the button LED will become
illuminated, indicating that the function is active.
Pressing the button again deactivates the function
and the button LED will turn off.
MODULES
When pressed and becomes illuminated, this
button displays in the CONTROL window a list of
the modules that are available to be connected to
the control panel.
The list shows the name of the module and the
connection condition (connected or not connected)
by means of symbols.
The symbols used are shown below:
This symbol represents a gateway.
This indicates that the unit is currently connected to
this control panel. Pressing the adjacent button will
disconnect the unit from the control panel.
This indicates that this unit is currently connected
to and locked by another control panel.
This shows that the unit is in the standby mode.
(i.e. currently not active but locked by this control
panel)
This represents a bridge connection
