6. RCU-01 Operation
Using the 'UP' and 'DOWN' buttons, you can scroll through the following screens;
Listed from the power up default and scrolling using the 'UP' button.
• Site name. Use this to verify the site.
• Type and version of the firmware, time and date of compilation.
• RCU time and date
• Connection Type. Regardless of the connection type set, if connected directly to the Host, the host can
connect. However, if an alarm is generated, the current connection mode will be used to contact the Host.
• Alarm Status. The number of pending alarms will be shown. 'IDLE' means no alarms.
• Event log status. The number of logged events is shown.
• The next 8 screens are the analog inputs. The top line shows the name of the input and the bottom line
shows the decimal analog value (between 0 and 255) and the scaled value with the units description.
• The next 24 screens show the state of the digital inputs and their given names. The S prefix on the top line
denotes that these are Status inputs.
• The next 24 screens show the state of the relay outputs. By simultaneously holding the ACTIVATE button
and the ON button, the relay can be pulsed. If the button is held in for more than 2 seconds, the relay will be
latched on. The 'C' prefix denotes a Control output. Note that outputs 17 to 24 are not implemented on the
standard units.
If you want to isolate the Relays from being operated from the Host, set the Keyswitch to LOCAL. You can
remove the key and keep it with you to prevent it being switched back for safety. Make sure it is set to REMOTE
when leaving the site, or the Host will not have control. The ACTIVATE switch has a LED which will flash in
LOCAL mode to remind you of this. While the switch is in LOCAL, no alarms will be generated.
• To change Connection Type, make sure key switch is set to LOCAL, then using the UP and DOWN buttons,
select the screen that shows 'Connection Type'. Whilst holding in the ACTIVATE button, scroll through the
connection choices with the ON key. When you have reached the correct one, press the OFF key. The
display should say 'Saved in EEPROM'. The new connection method is now saved permanently in the RCU.
• The 16 Status LED’s show their respective states as per the Site configuration.
• The 'AC POWER' LED shows that mains power is available to this unit.
• The 'ON LINE' will show if a valid connection is in progress.
• The 'RS-232 RX' LED shows data is being received.
• The 'RS-232 TX' LED shows data is being transmitted.
