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.
4.6 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.
4.7 Long Delay Setting
4.7.1 MDS 520 Digitrip Models
If any of the red LEDs are blinking press “Reset” on Digitrip.
•
Set the desired test value for the “Long Delay Setting” dial.
•
Set values for the “Short Delay Setting” dial to the maximum
value.
•
Set values for the “Ground Setting” Dial to the maximum value.
•
Set for the “Instantaneous” dial to “OFF”.
While performing MTK2000 testing, please validate the LTM jumper
is in the “inactive” position. Reference Section 2.3 MTK2000
Breaker Cables.
4.7.2 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
Delay Setting” dial 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 Long Delay pickup current level. Once the pickup cur-
rent 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.
4.8 Long Delay Time
4.8.1 MDS 520 Digitrip Models
If any of the red LED’s are blinking press “Reset” on Digitrip.
Do not change the “Long Delay Setting” dial.
Set the desired test value for the “Long Delay Time @6xIr” dial.
4.8.2 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 LD Time value goes up, if you raise the
multiplier higher the LD Time 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 Digitrip’s “Long
Delay Time @6xIr” dial 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.
4.9 Short Delay Settings
4.9.1 MDS 520 Digitrip Models
If any of the red LEDs are blinking press “Reset” on Digitrip.
•
Do not change the “Long Delay Setting” dial.
•
Set value on the “Long Delay Time @6xIr” dial to the maximum
value.
•
Set the desired test value for the “Short Delay Setting” dial.
•
Set value on the “Short Delay Time” dial to “.1” sec.
