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.
