Oven Not Ready Fault
Cause: The oven is not within 1 C of the set temperature.
Action: From a cold start the oven will require 20-30 minutes to reach the set
temperature. If you have loaded a new method or manually adjusted the oven
temperature allow 20-30 minutes for the oven to reach the set point and stabilize.
Cause: If you are in ECD view, this fault refers to the ECD oven.
Action: From a cold start, both the column oven and the ECD oven will require 20-
30 minutes to reach the set temperature. If you have loaded a new method or
manually adjusted the oven temperature allow 20-30 minutes for both ovens to reach
the set point and stabilize.
If the ECD reaches its set temperature before the column and PID, the Oven Not
Ready Fault will clear, but an oven fault condition remains. A fault status will be
displayed until the column and PID reach their set point.
Cause: The ambient temperature is below 0 C (32 F) or above 40 C (105 F).
Action: Move Explorer to a more controlled environment: indoors or inside
a vehicle.
Pressure Fault
Cause: The pressure in the internal carrier gas cylinder is low.
Action: Refill the internal tank as described in Filling the Internal Cylinder on
page 44 or connect the instrument to an external supply of carrier gas as described in
Connecting Carrier Gas on page 48.
Cause: The external supply of carrier gas is not connected properly.
Action: Ensure there are no leaks in the supply lines and that the delivery pressure is
set to 100 psig.
Cause: The Explorer is not within 0.5 psi of its set pressure.
