Description

Zebra VZ-7 Variable Speed Zebra Advanced ECM Motor Diagnostic Tool

Accurately diagnose exactly which component has failed in a Variable Speed system

The Variable Speed Zebra's control panel has only 4 switches, and is simple to operate. It is microprocessor controlled - letting you concentrate on the system, instead of learning a complicated tool. The LED's in the "Settings & Options" section on the left report the status of signals coming from the equipment's controller board (left) and going into the motor (right). The digital display reports CFM, RPM, volts, and any error codes discovered. Low control voltage is indicated by a flashing LED. Tri-Color LED's (right) indicate the options currently selected on the equipment's controller board. With it, a tech will be able to:

  • Visually monitor signal calls from the furnace/air handler circuit boards
  • Interrupt those signals and send the motor any signals you desire, to observe motor operation
  • Get a visual display of motor RPM and the calculated CFM (on most systems)
  • Get a visual readout of all 4 system "taps". These selections help set up a system correctly
  • Get a direct readout of the control voltage in the motor (low voltage here causes erratic operation)
  • And finally, IF a problem is traced to the motor, one switch press starts an automatic analysis to clearly indicate if the problem is in the motor's electronics, or one of 7 possible winding problems

Currently, the range of popular tools to understand these motors leaves something to be desired. ECM motor manufacturers report that fully 41% of the motors returned to them as "defective" actually have no problems at all. That statistic says that today's techs may not fully understand what's going on with these systems - and no wonder! - with as many as 21 wires connecting these motors to the control circuit board in the furnace or air handler, most technicians don't have the time (and often, the charts) required to monitor the various voltages and waveform signals going on in multiple lines simultaneously.
