If CSMUX is not in range, the red LED will go on and the test will stop.

If CSMUX is in range, the red LED blinks once and the test continues.

CHECK VFD — The VFD is factory wired and programmed for proper operation with the unit controls; no installation or service adjustments are normally required. At unit start-up, the VFD’s LED will display “0.0 Hz.” Refer to Fig. 33.

POWER UP LID DISPLAY — After completing the auto- matic run test, perform the following procedures to change the controller password, set the controller clock, configure sched- ules, set parameters, view settings, and view alarm history.

1.Set the Remote/Local/Off switch on the front of the unit to the OFF position. This prevents operation of the fan and compressors while still providing power to the unit controls.

NOTE: When the switch is in the OFF position, the red alarm LED will be lit; this is normal.

2.If the unit access panel (for power and controls) is still on the unit, remove it in order to view the control modules during start-up.

3.Switch the main unit power disconnect to ON.

When power is applied to the Omnizone™ system control panel, the red LED on the top front of the processor module will flash at a rapid pace (about twice a second) for the first 30 to 60 seconds. This rapid flash will then be replaced by a slower pace of about once per second.

The green LED below the red LED will start flashing. The green LED indicates input/output communications for accesso- ry input output modules and the LID display.

The yellow LED will flash when the controller is broadcast- ing CCN messages to a laptop or other computer.

The third LED from the bottom of the controller (PCB1) will light.

The LID display will show the controller identification, time and date as shown below.
