Operating Instructions for Standard HMI Control Panel

• A flashing Pretrip LED indicates that the
Pretrip Test is being initialized. When the
Pretrip Test starts, the Pretrip LED will glow
steady amber to indicate the test is in progress.
The display will show the Standard Display.
• The Pretrip Test will take about 20 - 25
minutes, depending on conditions.
IMPORTANT: The box temperature will vary
during the Pretrip Test. This is normal
operation.
When the Pretrip Test is complete or if a
Shutdown Alarm occurs, the amber Pretrip LED
will turn off.
Stopping a Pretrip Test: To stop a Pretrip Test at
any time, press the POWER OFF Key to turn the
unit off. This will generate Alarm Code 28 Pretrip
Abort. Other alarm codes may also be generated.
This is normal when the Pretrip Test is halted
before completion.
