
‘IB1 Drop-Out Time = ‘ ’50 mSec’ to ‘240 mSec’ (resolution is 1mS)

‘IB2 Drop-Out Time = ‘ ’50 mSec’ to ‘240 mSec’ (resolution is 1mS)

‘IB3 Drop-Out Time = ‘ ’50 mSec’ to ‘240 mSec’ (resolution is 1mS)

‘IB4 Drop-Out Time = ‘ ’50 mSec’ to ‘240 mSec’ (resolution is 1mS)

‘IB5 Drop-Out Time = ‘ ’50 mSec’ to ‘240 mSec’ (resolution is 1mS)
The Contactor Drop-Out Time values transferred from the IB units
will be available on DeviceNet in the following manner:

‘IB1 Drop-Out Time DIP Setting = ‘‘50’ or ‘75’ or ‘100’ or
‘130’ or ‘150’ or ‘175’ or ‘200’ or ‘240’ ‘Sec’

‘IB2 Drop-Out Time DIP Setting = ‘‘50’ or ‘75’ or ‘100’ or
‘130’ or ‘150’ or ‘175’ or ‘200’ or ‘240’ ‘Sec’

‘IB3 Drop-Out Time DIP Setting = ‘‘50’ or ‘75’ or ‘100’ or
‘130’ or ‘150’ or ‘175’ or ‘200’ or ‘240’ ‘Sec’

‘IB4 Drop-Out Time DIP Setting = ‘‘50’ or ‘75’ or ‘100’ or
‘130’ or ‘150’ or ‘175’ or ‘200’ or ‘240’ ‘Sec’

‘IB5 Drop-Out Time DIP Setting = ‘‘50’ or ‘75’ or ‘100’ or
‘130’ or ‘150’ or ‘175’ or ‘200’ or ‘240’ ‘Sec’
The IntelliVAC Plus measures the close time of the contactor that it
is controlling. This measurement determines the precise time from
when a Close command is issued, to the time that the Contactor
Auxiliary input status toggles to indicate a closed contactor state.
There will be a parameter sent from the IB unit that indicates the
close time of the contactor that was closed. The Close Times for all
of the five (5) contactors used in an MC system will be available on
DeviceNet in the following manner:

‘IB1 Pick Up Time = ‘ ‘000’ to ‘255mS’ (000 indicates contactor
has not been closed yet)

‘IB2 Pick Up Time = ‘ ‘000’ to ‘255mS’ (255 indicates contactor
did not close on last close

‘IB3 Pick Up Time = ‘ ‘000’ to ‘255mS’ command)

‘IB4 Pick Up Time = ‘ ‘000’ to ‘255mS’

‘IB5 Pick Up Time = ‘ ‘000’ to ‘255mS’
Before a contactor has been commanded to close, this time will be
set to 0mS. If a contactor does not close within the close time
period, which is programmed as 200mS in the IB unit, then the
contactor open routine will be initiated and a ‘Contactor Fails to Pick
Up’ warning will be generated, which the IntelliVAC Plus will
acknowledge and display (see Table 4.F – IB Fault/Warning
Descriptions). The general coil timing for a contactor coil is to
provide it with a 200mS close current of a large value and then to
decrease the coil current to a lower hold value for the remaining hold
