Operation
The E
3
Point gas detection system is factory configured to conform
to specific standards. It is designed to be operational after physical
installation and warm-up procedures.
Start-Up Procedure
Before applying power, check all wiring for continuity, shorts, grounds,
etc. After power-up, ensure the LEDs below are operational as follows:
Figure 4. E

Point LED
LED Description Display Modes
I/O Power
Always on = Normal operation
Always off = microcontroller fault or no
power
Blinking (twice per second) = self-test
1 Built-in sensor Alarm A
Always on = Alarm A triggered
Slow blink = Alarm B/C triggered (1 blink/
second)
Fast blink = Fault (4 blinks per second)
Always off = normal operation
2 Transmit
Blinks for communication and is always on
when transmitting
Always off = normal operation
When the unit is first powered up, sensors undergo a 5 minute warm-
up (15 minutes for the O
2
sensor), during which time the unit displays
Warm-Up.
Allow the sensor to operate for 12 hours with the enclosure sealed prior
to testing the sensors. This will give the sensor time to reach thermal
equilibrium to the external and internal temperatures while in operation.
