The System consists of 4 categories of tools, many of which are optional, so your System is customized to you, and to the way you work.

UZ-1
The Basic Tool is model UZ-1 - we affectionately call it the UZI. It is able to test run a motor in one or more (up to six) speeds. It has seven LEDs and three 3-way switches. It arrives with one popular adapter, which fits the very common GE/Regal-Beloit Series 2.0 and 2.3 motors.

Adapters Adapters couple the UZI to the motor. Six different adapters were available when the tool was released, with many more to come. In fact, we’re committed to making low-cost Adapters available for virtually every new ECM motor that is introduced into the HVAC-R Industry. The PWM Signal Generator Adapter will soon be available for testing motors that utilize PWM signal inputs.

Motor Plugs
Motor Power Plugs with Harnesses are necessary when you want to test a motor out of its air handler/furnace environment. Most ECM motors have special power input plugs, so bench testing can be challenging without access to these plugs. A wide variety is available, with more to come.

Accessories
Accessories round out the System: • A 24" extension for the tool’s main harness is available (it can also be used to replace the original harness if the fan wheel gets too close!) • A rugged accessory case is available to protect your Adapter and Power Plug collection from getting damaged or lost. • Other items will be added to this category as you ask for them.

The Universal Zebra Tool — Model UZ-1

• • • We’ve nicknamed the basic tool the UZI. It is able to test run a motor in one or more (up to six) speeds. It has seven LEDs and three 3-way switches. It arrives with one popular Adapter, which fits the very common GE/Regal-Beloit Series 2.0 and 2.3 motors. It is housed in a rugged, latchable case that protects the tool, the harness, and the power input clips. Inside the lid is a place for each Adapter's corresponding magnetic overlay card, which describes the functions of each switch and LED with respect to that specific motor series.

How Do You Troubleshoot the Problem?

The complexity of these new systems has caused a special method of troubleshooting to be applied. We call it the Divide-and-Conquer method. Since information about commands and signals being sent to the motors (and the responses coming back from the motors) isn’t always available to the Tech, a way of logically splitting the System into smaller sections and then testing each of those sections is necessary.
