3.4 Meaning of the EEXV Driver status LEDs
Under normal conditions, five (5) LEDs indicate:
• POWER: (yellow) remains On in presence of supply. Remains Off in case of battery operation
• OPEN: (green) Flashing during the valve opening. On when valve is fully open.
• CLOSE: (green) Flashing during the valve opening. On when valve is fully close.
• Alarm: (red) On or flashing in case of hardware alarm
• pLAN: (green) On during the normal working of pLAN.
In the event of a critical alarm, the nature of the alarm can be identified by observing the status of the LEDs as shown
below. Highest priority is level 7. When more than one alarm occur, only the one with the highest priority level is
shown.
Alarms that will
shutdown the system
PRIORITY LED “OPEN”
LED
“CLOSE”
LED “POWER” LED “ALARM”
Eprom reading error 7 Off Off On Flashing
Valve remains open on power
failure
6 Flashing Flashing On Flashing
At start up, wait for battery
loading (parameter……….)
5 Off On Flashing Flashing
Other alarms
PRIORITY LED “OPEN”
LED
“CLOSE”
LED “POWER” LED “ALARM”
Motor connection failure 4 Flashing Flashing On On
Sensor/input error 3 Off Flashing On On
Eeprom writing error 2 - - On On
Battery error 1 - - Flashing On
pLAN
LED pLAN
Connection OK On
Driver connection or address error = 0 Off
The Pco Master doesn’t answer Flashing
3.5 Addressing of pLAN
To get the correct functionality of the pLAN net system, it is necessary to address correctly all the installed components.
Each component has a number of microswitches that must be set as specified in the following table.
