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.
