ELAN AUDIO - SENTINEL / RCU-01 RCU01R02 PAGE 17/49
7.4 Site Status
When selected this window will automatically interrogate the RCU and retrieve version specific information from the
RCU. It will then commence periodic polling of the current RCU status. The update period is approximately twice a
second but this is dependant upon the connection mode.
This status information is a snapshot of the RCU at the time of the poll. Any analog or status input that is in the alarm
state will be highlighted in red. The state of the control outputs are also highlighted in red if they are active. The state
of the control outputs are also highlighted in red if they are active.
There are four tabs in this window:
Analog Inputs
The RCU will be connected to up to eight analog inputs. The status of each of these inputs is displayed graphically on
the Analog Inputs tab. The range over which a particular analog input would be in alarm is indicated by a red stripe in
the graphical meter. The current status of the analog input is displayed graphically by a needle. The needle is normally
black, and red if it is currently in alarm.
Status Inputs
The RCU may receive status information from up to 24 digital inputs. The Status Inputs tab displays the name and
status of each of these digital inputs. If a particular input is in alarm it will be written in red and a warning light will be
displayed.
Control Outputs
The RCU may be connected to up to 24 digital outputs. Each of these digital outputs may be configured to be latched
or pulsed. ( See also Site Control Output Configuration ).
According to the type of digital output, each will have a button adjacent to it enabling the output to either be pulsed or
latched on or off. Outputs latched on are displayed in blue text.
This function will only succeed if the RCU is in remote mode, it will not cause any change to the RCU control outputs if
the RCU is in Local mode. This is done to prevent a remote SENTINEL operator inadvertently operating a control and
potentially causing harm or damage to an technician on site.
If a control is latched on or off the control status display will show the resultant change, however if the control output is
pulsed then the status display will not show any change as it is not possible to poll the RCU during a pulse command.
Note: If there is any failure of the control command due to the RCU being in Local mode or due to communications
failure then an error will be reported to the user.
