Series 2000 LEDs

This section describes how to interpret information on the LEDs in the
Series 2000 controller auto calibration card and combustibles card.

Auto Calibration Card LEDs

All auto calibration card LEDs denote that the Series 2000 has sent out a
15-volt signal to the RCU to activate the appropriate solenoid. LEDs are
clearly labeled on the auto calibration card - 1 is on the far right of the
card as you look at it.

Combustibles alarm relays are labeled on the wiring card and in soft-
ware as Alarms 5 & 6. LED number 1 is on the far right of the card as
you look at it; LED number 2 is to the left of LED 1. All LEDs denote
an Alarm relay is energized (contact closed).
When Lit:
Combustibles 1 Combustibles Alarm #1 relay is energized
This corresponds to Alarm 5 in software.
Combustibles 2 Combustibles Alarm #2 relay is energized
This corresponds to Alarm 6 in software.
When Lit:
System is in calibration. This LED remains on for
the entire calibration cycle, then turns off during
the calibration recovery time.
o span gas solenoid is energized and the O

span gas should be flowing into the sensor.
o zero gas solenoid is energized and the zero
2
gas should be flowing through the sensor.
Combustibles span gas solenoid is energized
and the combustibles span gas should be flow-
ing into the sensor.
