NOTE: R = A reset is only possible with these designated outputs. Attempting to set these will have no
effect on the state of sealed alarms.
A simple example illustrates the methodology for resetting of the trip contact alarms within the TPU2000
TPU2000R. Figure 5-57 details the control step procedure for a unit with the default password setting.

Group VI Control Features Explained

Group VI is similar to the control provided in Group III. However, the control is not of the nature of a latched
command control. The control type is of a momentary nature. The selected Physical Output is pulsed for a time
duration set in the Breaker Failed To Trip Time Register. This register may be set to a value via ECP (External
Communication Program) WinECP (Windows External Communications Program) or Register 61424.
As noted in Table 5-52, momentary pulse of a Physical Output is available on the TPU2000 and the TPU2000R.
EXAMPLE 5 -Reset 46-1, 46-2 and 63 Alarm Status Bits.
STEP 1 -
Host sends following register contents
to initiate a reset of 46-1, 46-2, an 63
( Assumed that defaultpassword of all spaces
is active).
41441 = 2020 hex (Password Hi)
41442 = 2020 hex (Password Lo)
41443 = 0 (Reserved)
41444 = 0000 hex (Change Select Mask 1)
41445 = 7000 hex (Select Trip ABC Bits Mask 2).
41446 = 0000 hex (Change Select Mask 3)
41447 = 0800 hex (Change Select Mask 4)
41448 = 0000 hex ( Set/Reset Mask 1)
