Single-coil Testing Using a Test Reference
This application involves setting up a new Test ID that will include a test reference to be used when testing other
devices of this type.
1. Connect the power pack’s test cables to a known-good coil as described in the table below.
Table 15:

Setting up the Test ID
1. Set the power pack’s Function Selector switch to Surge testing (surge icon).
2. Set the Test Select switch to Lead 1 .
3. Set the Ramp Rate switch to 3 or 4 to start. You can adjust the rate as desired when testing the first coil.
4. Ensure that the Zero-start Override key switch is in the Ramp position (vertical—ZSO off).
Fig 33: PPX30A Zero-start override key switch.
Item Description
1 Zero-start override. This key switch overrides the Zero Start function and allows the unit to
immediately apply the full target voltage level to the test leads. With the key in the vertical
position, testing starts at zero volts and must be ramped up to the target voltage level.
2 In the horizontal key position, zero-start override is enabled. When the zero-start override
feature is enabled, target test voltage levels will be instantly applied to the test leads when a
test begins.
5. Create a separate Test ID and a Motor ID to use during the testing process. The Motor ID and Test ID can then be
re-used when testing other devices of this type.
6. During the Test ID setup, you will define a test reference.
7. Open the
Tests tab.
8. Click on Edit Test ID .
9. Enter the password as needed.
10. Click on Add .
11. In the Create New Test ID dialog box, click on Add Blank Test ID .
12. Give the new Test ID a name that describes its function.
13. Enter the
Target Voltage Motor Class then click OK .
14. Upon returning to the Tests tab, you should see the new Test ID displayed in the Test ID field.
15. Create a new Motor ID for the devices you will be testing. Be sure to select the new Test ID during the process.
