UMMARY
The Model 10410 has 3 LCD temperature displays and three LED status displays for
each active channel (2 green, 1 red per channel). Channel 1 is a standard active
channel (4°C). Channels 2 and 3 alternate on a freeze / thaw cycle between -7°C
and ambient.
The “Ready” Green LED’s come on when the relay set point temperature is reached
for each channel.
The “Slip” Green LED on Channel 1 lights up immediately upon power-on, indicating
that the water slip relay (optional upgrade) is not actuated, which is the expected
normal condition. If the “Slip” green LED goes out, this indicates water is “slipping”
past the heat exchanger. The relay then shuts off the sample pump so that water is
not allowed to reach the analyzers, preventing damage to the analytical instruments.
Steps need to be taken at this time to determine the cause of the moisture and
correct the situation.
The “Failure” red LED’s come on if the thermocouple or an electronic controller
component has failed.
You can determine whether Channel 1 or Channel 2 is currently the frozen impinger
since the “Active” green LED will light on the active channel.
READY LED On = Relay set point temperature is reached
SLIP LED On = Safe operating condition
SLIP LED Off = Water slip sensor alarm (unsafe operating condition)
Red LED On = Thermocouple or electronic failure alarm
ACTIVE On = Indicates whether Channel 1 or 2 is operating in freeze cycle
When all Green LED's are lit, the Model 10410 is operating at proper cooling block
temperature, producing a stable, repeatable dewpoint, sample effluent. If a green
LED fails to light, it can indicate several problems. The first and most obvious is
overload. Check the incoming sample gas temperature, moisture content, and
flowrate through the heat exchangers to be sure all conditions are within published
specifications. Overload requires more cooling power from the Model 10410 than is
available. If all conditions are correct, then the problem is an electrical malfunction,
which can be traced using the troubleshooting in this manual.
