Programming Settings
The Recloser Settings Tab appears when the Recloser
Programmer Software is loaded and opened. See Figure 6-2. At
this point, changes to the settings can be made as required for
the recloser’s particular application. When settings changes are
complete, the “Write Settings To Recloser” button will allow the
settings displayed to be stored in the recloser. Notice that settings
fields that are not identical to what is actually stored in control
memory are displayed in red until they are committed to memory.
From this point forward the recloser will use these new stored
settings. These settings can be checked at any time by clicking the
“Read Settings From Recloser” button.
Minimum Trip Value
The Minimum Trip Value is the minimum current sensed that will
cause the Recloser to trip. This current is programmable from
30A to 800A for Versa-Tech I and 30A to 200A for Versa-Tech
LT in 10A increments. The control will begin counting towards
meeting the selected time current curve when there is a half cycle
of current above this threshold. The current level is measured
by sampling and finding its peak value. The sample frequency
for current measurement is 1.04ms. This gives 16 samples per
60Hz cycle. Sliding window approach is followed to perform
current measurement. Current measurement is on half-cycle
basis. Hence, to assert a fault (current above Min. Trip), at least 8
samples are required.
Non Reclose/Hot Line Tag
The Non-Reclose handle has a dual functionality when the option
‘Non-Reclose/Hot Line Tag’ is selected by the proper radio buttons
on the main "Settings" tab of the user interface. In this mode,
when the red handle is pulled to the down position once (rotate
90° in the clockwise direction) the recloser is placed in the
traditional Non-Reclose mode using whichever curve is selected
to lockout on TCC1 (See Recloser Operation Section). However,
if the red handle is cycled (pull the handle down and up) twice
and the handle is brought back to the down position within 30
seconds, the unit is now placed in Hot Line Tag (HLT) or the
instantaneous trip mode. When the user selects the ‘Hot Line Tag
Only’ option in the Settings, the Non Reclose handle will function
always as HLT when the handle is pulled down( rotated 90° in
the clockwise direction). A unit placed in HLT mode is always
accompanied by a characteristic pulsed strobe of the beacon
serving as a visual indicator confirming the HLT mode. Hot Line
Tag takes precedence over Cold Load time.
Note for Versa-Tech I Reclosers with FW 4.xx:
When the recloser locks out on a HLT mode dropping the Manual
Operating handle (yellow), the unit would be able to close back in
only after the HLT mode is removed meaning that the Non-
Reclose handle (red) has to be manually returned to the normal
position to disable the HLT function and then the Manual
Operating Handle is to be rotated 90° in the anti clockwise
direction for the recloser contacts to close back in.
NOTE: Units manufactured prior to August 2011 will not have the
dual functionality of the Non-Reclose Handle. However, these
units would have dedicated options for the Non-Reclose and Hot
Line Tag modes that can be enabled through the User Interface.
Settings Tab
Operations to Lockout
The control can be set to 1, 2, 3, or 4 operations before the
recloser goes to lockout.
Manual Closing Delay Time
The time from when the manual handle is activated until the
recloser begins closing the circuit can be programmed from 0 to
30 seconds. The actual delay may be a few seconds longer than
the time programmed.
Sequence Coordination
The sequence coordination feature if enabled will prevent
unnecessary operations of the recloser when used in a series
arrangement upstream from other fault interrupting device. If
the recloser senses current above the minimum trip level for a
duration shorter than the programmed control response time,
then the recloser will internally advance its software count by one
without tripping. This action allows an upstream recloser to stay in
proper sequence when faults are cleared by downstream recloser.
False counting is avoided by applying hysteresis to the minimum
trip threshold. The current must increase above the minimum
threshold and then decrease to 87.5%of the trip threshold before
a count is registered. The count is remembered for the reset time.
Versa-Tech I Reclosers with FW 3.xx and Versa-
Tech LT
Reclosers:
When "Sequence Coordination" box is checked, sequence
coordination is applied to all programmed shots.
Versa-Tech I Reclosers with FW 4.xx:
Sequence coordination is allowed to be made shot specific by
using the software and choosing the TCC curves where the
Sequence Coordination should operate on. This is accomplished
by selecting the check boxes for Sequence Coordination under
the respective TCC curves on the User Interface. Sequence
coordination would be applicable only on the checked TCC curves.
By checking the SC on lockout option, the recloser would trip
on TCC2 for a permanent fault that the unit would see past the
operations to lockout. For example: If the unit has 4 operations to
lockout with the SC Lockout option checked and the unit sees a
permanent fault that didn’t clear after 4 downstream operations
by the downstream devices, the recloser unit would lockout out
on the delayed TCC2 curve which would appear as a 5th actual
operation after recording 4(SC) events in the event log.
However, user can uncheck this option on the User Interface and
the recloser would continue to record all the downstream blinks
or the faults that didn’t engage Versa-Tech TCC curves on the line
as 5(SC) 6(SC) 7(SC) so on. Note that the unit would still lockout
on the delayed curve (TCC2) when the unit sees a permanent
fault which was not cleared by the downstream devices in either
situations. (See Control Programming > Event and Data Logs >
Sequence Coordination Events Logs Section).
