Contactor Drop-Out Time
Contactor Drop-Out Time is the amount of time that will pass from
when a Close command is removed to the time that the Contactor
Auxiliary input indicates that the contactor has opened.
With the IntelliVAC Plus unit the Contactor Drop-Out Time settings
will be altered via a parameter which has the following
range/resolution:

50 mSec to Maximum 240 mSec. with 1 mSec. resolution
The default value of the Contactor Drop-Out time will be dependant
on the Drop out Time settings from the IB unit, in the following
manner. The Contactor Drop-Out time will be set to the Contactor
Drop-Out time sent from the IB DIP switches (50, 75, 100, 130, 150,
175, 200 or 240 mSec). Furthermore, in Version 4.006, the drop out
time is 6ms longer than the values give here if the close command is
given through IB. This will only occur for the first time, after power
up, that the Contactor Drop-Out Time is read from the IB. From then
on, the source of the Contactor Drop-Out Time will be determined
from a parameter that indicates if the source of the Contactor Drop-
Out Time is taken from the IB DIP switch or from a DeviceNet
setting. The parameter which is used to determine the source of the
Contactor Drop-Out Time and will be set on DeviceNet in the
following manner:

‘Drop-Out Time Source = ‘‘IB’ or ‘DeviceNet’
This parameter will affect all five of the IB units in a MC system
This scheme will allow having a Contactor Drop-Out Time value
from the IB and IE unit, with both values being visible and a third
parameter which indicates which of the two parameters will be used
for control of the contactor.
The Contactor Drop-Out Time will be available, for each of the five
(5) IB units, on DeviceNet in the following manner:
