If the equipment requires it, respect staging precedence. (i.e.: Do not turn on stage two if stage one is not already activated.) Ÿ ZebraStat Do not allow your to get wet. If it does get wet; dry it thoroughly before using. -
Page 4: Using The Zebrastat
Using the ZebraStat ZebraStat To use your , follow these steps: 1.) Decide the Mode Hook up appropriate leads. Manipulate Mode & Component switches. Observe the LED’s and equipment tested. Explanation of steps: ZebraStat 1.) Mode: operates in three different modes. You can easily leave it hooked up and use all three modes on the same equipment as needed. - Page 5 2.) Hook-Up - Start with the mode switch in the ANALYZE position and have all component ZebraStat switches OFF. The hookup of the ’s leads is the same for all modes. Connect the leads to their respective wires at the equipment.

Page 6: Continuity Mode
Continuity Mode Continuity Mode tests that the wires your ZebraStat ’s leads are connected to ‘go somewhere’ electrically. For instance, the wire that you connected the FAN lead to normally goes through a fan relay. Using this mode will tell you if there is a continuous circuit through that relay on the other end of the wire. - Page 7 ZebraStat ’s tiny (about 7 milliamps) of current to test the different circuits. Be aware that some circuits might possibly be activated while testing in Continuity Mode.

Page 8: Analysis Mode
For instance, you turned the FAN switch on at the thermostat, but the fan does not start. Observing a lit yellow LED in the FAN section of ZebraStat connected to the equipment would tell you that the signal is getting to the equipment (suggesting a problem inside the equipment.) If the corresponding LED was NOT... - Page 9 ZebraStat Attach the ’s leads to the appropriate equipment wires, then attach the red and blue power leads to the equipment’s 24VAC hot and common wires, observing polarity. Notice which yellow LED’s are illuminated under their component switches. (All of the component switches must be OFF.) These...

Turn all thermostat functions to OFF. ZebraStat Turn all of the ’s component switches to OFF, and put the mode switch in the ANALYZE position. - Page 13 Caution: Remote activation can surprise another technician working elsewhere on related equipment. Communicate your intentions to anyone else involved. For instance, when remotely activating the cooling stages of a system; you don’t want to start a fan o r c o m p r e s s o r t h a t s o m e o n e m a y b e inspecting.

Page 14: Troubleshooting Electronic Boards
Electronic Boards A blown fuse on an electronic control board presents special challenges. Rather than just replacing the fuse (and possibly watch it ZebraStat ‘blow’ again) the offers a diagnostic alternative. The white wire (the HEAT1 circuit) has a special function built into it. Between the red and white wires is a low-amp, auto- reset, solid-state ‘circuit breaker.’... - Page 15 ZebraStat If the current flowing into the through these two wires should exceed 3 Amps, the breaker will ‘trip’, and the lower Trip LED will light. The breaker will stay in this ‘tripped’ condition until the power is removed from one of the leads for about 15 seconds.

Page 16: Voltage Problems
ZebraStat has a built-in voltage monitor section that makes it easy to tell if the voltage being supplied at the red and blue leads is adequate. - Page 17 20.5 volts. The OK LED glows about half-brightness at 21.5 volts, and is fully bright at 23 volts. ZebraStat Any time that you are using the notice that the OK LED isn’t fully lit, you may want to check the voltage level at the component that is farthest away from the system transformer while under load.

Page 18: Circuit Protection
‘hot’ lead to touch ground, you will probably ‘trip’ this circuit protection shutting down the ZebraStat, and turning on the red TRIP LED. The unit will remain in the tripped condition until you remove all power to the unit for about 15 seconds. -
Page 19: Avoiding Problems
The RED lead must connect to the equipment’s HOT wire (usually red), and the BLUE lead must connect to the equipment’s COMMON wire (usually brown or blue.) REVERSING THESE ZebraStat LEADS CAN CAUSE THE ’s CIRCUIT BREAKER TO TRIP. If you are getting a strange LED indication in... -
