PN 903-8797, Rev A
Alarm LED Status
The LEDs on the User Interface are numbered 1–7, from left to right. A lit LED
indicates that the condition associated with the LED currently exists. Four (4)
of the seven (7) LEDs indicate the status of corresponding alarms set by four
alarm relay contacts (two LEDs and their associated alarm relay contacts are
not currently used). The alarm setpoint values for the HCDP temperature are
preset at the factory, but can be changed in the eld.
The conditions which dene the Warning and Fault alarms are part of the
built-in, continuous diagnostics function. The HCDP temperature alarms will
be set at the end of the Cooling Stage, if the conditions that trigger the alarm
are present. The remaining alarms are set at the end of the stage where the
problem occurred.
The LEDs and their corresponding conditions when turned On are:
