The monitoring unit 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 LVD (low voltage disconnection) is closed.
The green LED blinks during a battery test.
If the LED remains OFF, it means the LVD is open.
• 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)
NOTE:
IEC C16 is a high temperature inlet which requires IEC C15 plug
IEC input voltage limitations are shown in section 2.4
