Rockwell Automation 1503VC IntelliVAC Plus Contactor Control Module - Manual (Page 62)

Description of Features 4-35
1503-UM054C-EN-P – June 2013
Programming Base Unit(s)
This is a Normal firmware flashing condition and no additional
action is required.
The Basic module is in the process of being flashed from a PC over
the RS485 communications link. The data rate for this process is
9600 baud. See Chapter 8 for Firmware Flashing.
The Plus status LED is flashing Green at a 0.50Hz rate so that the
LED is on for 1 second, then off for 1 second and then it repeats.
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 for 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 IntelliVAC Plus status LED is off.
RTC Fail
This is a Warning condition which may not be rectified by the user.
Refer all servicing to qualified service personnel, or see the trouble
shooting section in Chapter 10.
The Real Time Clock circuitry is not responding which will prevent
the Event Log (see Event Log in Chapter 4) from time stamping
events with the correct local time.
The Plus status LED is pulsing Green with a pattern of 2 pulses.
