5.3 Setting the Rating Plug
Press
Start
to set the rating plug value on the MTK2000 by using
the scroll up and down button . Press
Test Select
button when com-
plete .
5.4 Setting the Frequency
Press
Start
to set the frequency value on the MTK2000 by using
the scroll
Up and Down Arrow
. Press
Test Select
button when
complete .
5.5 ZSI Shorting Plug
The MTK2000 will ask if the ZSI Shorting Plug is installed, please
validate if it is installed (Reference Section 2 .4 Zone Interlock
Shorting Plug), if the correct answer is not shown, press
Start
then
scroll the
up and down arrows
to find the correct answer . Once
the correct answer is shown press
Test Select
.
ote:
N
If the shorting plug is present the short delay time and ground fault
time can be calculated by the MTK 2000 .
If the shorting plug is not present and the answer to this query is
“Yes”; both the Short Delay Time and Ground Time test will “Fail”
on the MTK2000 .
If the shorting plug is not present and the answer to this query is
“No”; both the Short Delay Time and Ground Time test will be a
“Pass” on the MTK2000 .
5.6 Self Calibrate
This should be done for every MAGNUM breaker
Press
Start
Once the calibration is complete the MTK2000 will say “Calibration
Complete” press
Test Select
to Return .
5.7 Long Delay Setting
5.7.1 MDS Digitrip Models
If any of the red LEDs are blinking press “Reset” on Digitrip .
Set value for the “LONG Slope” function to “I
2
T” .
ote:
N
The MTK2000 is not programmed to test the Long Delay I
4
T or IEEE or
IEC slopes .
Set the desired test value for the “LONG PU” function .
For test purposes set the “Long Memory” function is set to “OFF ”,
Reference Section 2 .3 MTK200 Breaker Cables .
Set value for the “SHORT SLOPE” to “FLAT” .
ote:
N
The MTK2000 is not programmed to test Short Delay with I
2
T slope .
•
Set value for the “SHORT PU” function to maximum value .
•
Set value for the “INST PU” function to “OFF” .
•
Set value for the “GND PU” function to maximum value .
•
Set value for the “GND SLOPE” function to “FLAT” .
The MTK2000 is not programmed to test GROUND Delay with I
2
T slope .
Once all selections have been made, press “Save” under the “Edit
Value” Menus buttons .
5.7.2 MTK2000
“LONG DELAY TEST” should be shown on the screen if not press
Test Select
until “LONG DELAY TEST” is on screen . Press
Start
.
The MTK2000 display is specifying that values need to be set, these
values were set in the Digitrip Instructions . Press
Start
.
Set “r” value on the MTK2000 display to match the Digitrip’s “Long
PU” settings by scrolling the
up and down arrows
.
Once value is set press
Start
on MTK2000, the test kit begins to
generate current . Begin to press the
Up Arrow
until the “Unit
Status” LED on the Digitrip begins to flash quickly . This should
occur at the pickup current . Once the pickup current value is
found press the
Start
button . A message of “TEST TERMINATED
->PASSED” or “TEST TERMINATED ->FAILED” will appear on the
MTK2000 display . The current level is the Long Delay Pickup Value,
this is the value where the trip unit will
Start
timing for Long Delay
(overload protection) .
ote:
N
If the Start button is not pressed, the test times out after 40 seconds .
ote:
N
The rate of the Status LED flashing will slow to normal when the cur-
rent is lowered below the pickup setting .
5.8 Long Delay Time
5.8.1 MDS 1150 Digitrip Models
If any of the red LEDs are blinking press “Reset” on Digitrip .
Do not change the “LONG PU” function .
In the Program Settings menu set the desired test value for the
“LongTIME” function .
Once all selections have been made, press “Save” under the “Edit
Value” Menus buttons .
5.8.2 MTK2000
After the “LONG DELAY TEST” pick up current is found press
Test
Select
on the MTK2000 .
ote:
N
If
Test Select
is hit more than once, the MTK will skip the next test
sequence . The only way to return to the time test is to redo the Long Delay
pick up current test .
The next value that needs to be set on the MTK2000 display is
“mult” the multiplier setting for the “Long Delay Time @6xIr” . (The
standard multiplier is 6 hence the statement “@6xIr” . If the multiplier
is changed lower than 6 the actual LDT value goes up, if you raise
the multiplier higher the actual LDT value goes down . When you
leave the multiplier as 6, the TR value and the LDT value stay the
same .)
Press
Test Select
on MTK2000 .
Set “Tr” value on the MTK2000 display to match the Digirip’s
“LongTIME” value by scrolling the
up and down arrows
.
Once value is set press
Start
on MTK2000 .
A message of “LONG DELAY PASSED” or “LONG DELAY FAILED”
will appear on the MTK2000 display .
5.9 Short Delay Settings
5.9.1 MDS 520 1150 Digitrip Models
If any of the red LEDs are blinking press “Reset” on Digitrip . .
•
Do not change the “LONG PU” function .
•
Set value for the “LongTIME” function to maximum .
•
Set the desired test value for the “SHORT PU” function .
•
Set value for the “SHORT TIME” function to “ .1” sec .
•
Set value for the “INST PU” function to “OFF” .
Once all selections have been made, press “Save” under the “Edit
Value” Menus buttons .
