STATUS Indicators Before Startup
When power is applied from the line disconnect switch and before the POWER ON (I) button is pushed, the
coolant flow LED will be illuminated. Once the POWER ON button is pushed and held for a few seconds, this
LED will extinguish if the system is in proper working condition.
Other fault conditions may also be indicated when the line power is switched on. Be sure to press and hold
the power supply POWER ON (I) button (in some cases up to 1 minute) to extinguish all status indicators. If
any LEDs remain illuminated, shut down the system and correct the problem. See Status LED
Troubleshooting in Section 8, if necessary.
