2.6.3.5 LED
S
The monitoring module has six LEDs located on the front panel. These are used to display the status of the
controller, LVD, system and battery:
• Controller status Green LED indicates MCU and Comp@s functions are OK.
Green LED is blinking if no Comp@s is present.
• LVD OK Green LED indicates the LVD (low voltage disconnection) is closed.
If the LED remains OFF, it means the LVD is open.
The Green LED blinks during a battery test
• 1 Major alarm Red LED indicates a major alarm in the system (defined in the alarm table).
• 2 Minor alarm Red LED indicates a minor alarm in the system (defined in the alarm table).
• 3 Battery alarm Red LED indicates a battery failure.
• 4 AC failure alarm Red LED indicates a mains failure.
2.6.3.6 USB
PORT
The USB port is designed for connecting a computer to the system controller via a standard USB cable (type
A/B), with direct access to the Comp@s software (Comp@s card required).
2.6.3.7 E
THERNET PORT
The Ethernet port is designed for connecting the controller to a user network (TCP/IP secured by user) via a
front panel RJ-45 jack and a standard network cable.
2.6.3.8 B
ATTERY TEST SAVE
This button can be used for starting a battery test (see section 4.4.3 for more information).
2.6.4 Distribution Unit (only for stand-alone systems)
Figure 8 : Distribution unit
Adding the modular distribution unit creates a stand-alone energy system. In combination with the low profile
MCU and the front signal connection card, the resulting system provides full front access installation.
The distribution unit includes an internal LVD (low voltage disconnection) in order to protect the battery from a
deep discharge. The LVD will stay open if the polarity of the battery does not match the polarity of the system
DC bus or if the battery voltage is out of range.
