INVERTER PHASE CHECKER (CL-MC02B)- Instantly analyses compressor or inverter fault - on site- Fits easily within a toolbox - only 69 x 115 x 28mm(2.72 x 4.53 x 1.10 inch)- Fast visual display DESCRIPTIONAir Conditioning Inverter Compressor Phase Checker The "Inverter Phase Checker" is the perfect low-cost answer to a Contractor's problems when an inverter-controlled air conditioner fails. The difficulty is always to know whether it is the compressor or the inverter which is giving trouble - and the Inverter Phase Checker can help to tell you which is faulty. The supply connections are disconnected from the compressor, and are connected to this module. When the inverter is switched on the six lights on the module should light up Red, Yellow, and Green. If the inverter PCB is faulty, one or more of these lights will not switch on, and this indicates the position of the fault. - If all six lights are on, the PCB is fine, and the fault is with the compressor. - If they are not all on, or one light is significantly dimmer than the rest, then the fault is with one or more of the output transistors on the PCB, or with the drive circuitry. The Inverter Phase Checker is small enough to drop into the toolbox, and will always help with the analysis of problems on site. A kit of connection leads is available for use with this indicator. The three leads are each 1 meter long and fitted with insulated 1/4" female Fastens for connection to the indicator box. Although small, it is not intended to be hand-held, and of course, all power supplies must be safely turned off while the module is being connected.
