No Power from IB or DeviceNet
This is a Normal condition if there are no input power sources to the
IntelliVAC Plus module. If this condition exists and there is at least
one source of external power supplied to the IntelliVAC Plus unit
then a serious problem may exist. Refer all servicing to qualified
service personnel or see the trouble shooting section in Chapter 10.
The Advanced module has no power from either the Basic module or
from DeviceNet.
The causes of the loss of Basic module power are either that there is
no 120/240V mains input power to the IntelliVAC plus module or
that this input voltage is <50Vrms. Also, the internal DC power
source on the Basic module has failed or the internal DC power
source on the Advanced module has failed, or both. Also, there is no
DeviceNet power or the internal DC power source of the Advanced
module has failed.
The DeviceNet status LED is off.
In Standby – Needs Commissioning
This is a Warning condition and indicates that the IntelliVAC Plus
needs commissioning due to a missing, incomplete or incorrect
configuration.
The DeviceNet status LED is flashing Green.
Normal Operation
This is a Normal condition and indicates that the IntelliVAC Plus is
operating in a normal condition.
