EC150 CO

O Open-Path Gas Analyzer

8.7 Troubleshooting

8.7.1 Data Loss During Precipitation Events

In extremely humid environments or after a precipitation event, data loss can

occur. Wicks on the analyzer windows help mitigate some of these data loss

events but cannot control for all conditions. In addition to wicking, heaters in

the snouts can aid in the prevention of data loss during precipitation and

condensation events. The heaters are automatically controlled by the EC100

electronics. The automatic heater control is activated using the Device

Configuration or ECMon software. A value of −1 turns the automatic heater

control off and a value of −2 turns it on.

8.7.2 EC100 Diagnostics for Gas Analyzer Troubleshooting

Before troubleshooting and servicing the analyzer, become familiar with

Section 2, Cautionary Statements.

The EC100 is also programmed to recognize problems with an associated gas

analyzer and reports those with LED status lights and diagnostic flags. The

two types of warnings are described in the sections that follow.

8.7.3 LED Status Lights

The EC100 has three LED status lights located in the upper left corner of the

front panel which provide immediate visual feedback and warn the user of

potential problems with the measurements. During normal operation all

STATUS LEDs should be green as shown in FIGURE 8-3.

• POWER Status LED

The POWER status LED will turn red if the supply voltage is outside the

specified limits (see Section 5.4, Power Requirements). The user should

check the battery voltage or the power supply voltage and ensure that the
