Rockwell Automation 1503VC IntelliVAC Plus Contactor Control Module - Manual (Page 344)

Parameters B-169
1503-UM054C-EN-P – June 2013
Altitude Settings on MC Units Inconsistent
[MC Altitude Set Warning]
Parameter Number: 327,269,211,153,94.
Access rule: Get
Data Type: BOOL
Object Mapping: 0xB4-1-122
Group: Diagnostics
Units: -
Minimum Value: 0 = Not Fault
Maximum Value: 1 = MC Altitude setting inconsistent
Default Value: 0
This parameter allows the user to view the status of the Altitude
settings from the various IntelliVAC MC units. If this bit is a ‘0’
then all MC units have the same altitude setting and no further action
is required. If this bit is a ‘1’ then not all of the MC units have the
same altitude setting.
Since all of the contactors in an IntelliVAC MC system will be
located at the same altitude, the altitude parameter should be the
same for each of the units. If all of the units are not set to the same
altitude, then there will definitely be a problem with the coil
operating currents of some of the units. See Table 8.A for setting the
altitude parameters for each of the IB units in an MC system.
Time Delay UnderVoltage Time Source
[TDUV Time Source]
Parameter Number: 328,270,212,154,95.
Access rule: Get/Set
Data Type: BOOL
Object Mapping: 0xB4-1-123
Group: Diagnostics
Units: -
Minimum Value: 0 = From IB
Maximum Value: 1 = From IE
Default Value: 0
This parameter allows the user to view and set the status of the
TDUV Time Source. If this bit is a ‘0’ then the IB DIP switch
setting is used as the TDUV Time Source. If this bit is a ‘1’ then the
IE setting in DeviceLogix is used as the TDUV Time Source.
