Can the PD Tester Test any panel?
Yes. The PD Tester will test any panel that has input connectors and output connectors. As long as you can physically connect the panel to the tester, it can test it. The PD Tester doesn’t care that the input system is different from the output type (such as 3-phase input and single-phase output).
We have special outlets that connect our standard system to common vendor outlets. Can these be tested?
Yes. Simply connect the male end of your special outlet into the PD Tester and the female end into an adapter (that you build) which plugs into the PD Tester. Even if this special outlet has a 3-phase input and a single-phase output, the PD Tester will still test it properly. The User's Guide (provided with the tester) describes how to build adapter cables, and the guidelines to follow.
Most of our panels use Cam-Lok inputs, but I don't see any connectors on the tester. Why not?
Adapter cables work best for this task. The original concept for the PD Tester had Cam-Lok connectors, but it was realized that this was counterproductive for the operator. Unexpected errors would be introduced into the testing because five separate conductors needed to be connected between the tester and the device. An adapter cable would use an L21-20 connector at the tester and Cam-Lok connectors at the panel. Not only is this easier to handle, but it leaves less chance for miswiring.
We don't use the orange pin and sleeve connectors shown on the PD Tester photograph, but we do use other connectors. Can these be swapped out?
Yes. The configuration of connectors on the front of the PD Tester is entirely dependant on the cables and panels you use. You can add any type of connector to the tester that you want. You can also remove any of the standard connectors from the tester that you don’t use. This will reduce the cost of the tester.
Can I test my generators?
NO. The PD Tester is designed to work with only non-active cables and panels. Both ends of a device need to be connected to the tester for it to perform its diagnostics. There is no way to test a generator without the generator operating, and this would destroy the tester.
Will the PD Tester test transformers?
No. Transformers require AC power to operate, and the PD Tester uses DC pulses to diagnose cables.
What happens if someone accidentally connects live power to the PD Tester?
It is important to train personnel in the operation of the PD Tester to prevent this from happening. However, accidents will happen. The tester is designed to protect itself from this happening, but some of the input circuitry may be damaged in the process (by design). The first stage of defense is with low-amperage fuses. If these do not trip fast enough, isolation relays will separate the high-voltage input from the computer. If the situation is severe enough, the isolation relays will also be destroyed, but the main computer will be protected. The self-diagnostic circuitry examines these devices to determine if any of the components have been violated by high voltage.
