4-12 OPERATION
4.06 Power Supply Status Codes
On start-up and during operation, the power supply control circuitry performs various tests. If the circuitry
detects a condition requiring operator attention, the status indicator on the control panel flashes a 2-part code
to indicate a code group and then a particular condition within the group. After 4 seconds, the sequence
repeats.
Example: Indicator flashes 4 times; the condition is in group 4. After a 1.2 second delay, the indicator blinks
3 times; the condition code is 4-3, indicating that the coolant is overheating. After a 4-second delay, the
indicator repeats the sequence until the condition is corrected.
Some conditions can be active indefinitely, while others are momentary. The power supply latches momentary
conditions; some momentary conditions can shut down the system. The indicator may show multiple condi-
tions in sequence; it is important to recognize all possible conditions that may be displayed.
NOTE
These codes are for systems with Firmware versions 2.4 or later. If your system’s Firmware is a prior
version, contact your distributor for updates.
