LED Status Indicators
This section describes the functional purpose of the LED Indicators in three categories, See Fig. 6 for locations.
• Output Indicators (see Table 2)
• Power and IO Module Status Indicator (see Table 3)
• COM Port Status Indicator (see Table 4)
NOTE: To avoid damage to the I/O module do not remove power from the Novar ES3.S until the System Status LED illu-
minates continuously, or a period of over 10 minutes has expired.
Table 2. Output Indicators on Interface Board.
Indicator Name Description
Class 2 Output 1 Class 2 Outputs 1 through 8 indicate that the normally open relay outputs are in the energized or
closed position(s) (closed contacts).

System Fault
Output
System Fault Output indicates that the normally open fault relay contact is in the energized position.
Table 3. Power and IO Module Status on Interface Board
Indicator Name Description
System Status Off: If the Novar ES3.S has been powered for at least 10 minutes and the System Status LED fails to
illuminate, this may be an indication of a system or I/O module fault. Contact Novar technical
support for assistance.
On: I/O module is configured and OK and is ready for operation.
Off or Blinking: If the Novar ES3.S has been powered for less than 10 minutes and the System
Status LED fails to illuminate, or is blinking, the I/O module may be receiving a system update.
Power When lit, the green Power LED indicates that system power has been applied. If the Power LED does
not light while power is applied, contact Novar for technical support.
Power Fault When lit, the red Power Fault LED indicates that the Novar ES3.S power circuiting has detected that
the AC voltage applied to the Novar ES3.S is greater than the maximum specified and has shut
down. Once the Power Fault LED illuminates, power will remain off until the over voltage situation
has been corrected.
AC Fault When lit the red 'AC Fault' LED indicates that one side of the transformer powering the Novar ES3.S
is tied to ground. Although the unit will have functionality in this condition, performance will be
reduced. Therefore, the cause of the fault must be identified and corrected for proper operation.
Table 4. COM Port Status Indicators on Mezzanine Board
Indicator Name Description
TX1/RX1 These LEDs show the transmit/receive status of Com Port 3.
TX2/RX2 These LEDs show the transmit/receive status of Com Port 5.
TX3/RX3 These LEDs show the transmit/receive status of Com Port 6.
TX4/RX4 These LEDs show the transmit/receive status of Com Port 4. The RS485 com port 4 is labeled
NETWORK "D" on the transition board of the Savvy Base. (Terminals 71, 72, 73)
