Servicing and Cleaning Wipe the case with a damp cloth and mild detergent Do not use abrasives or solvents Dirt or moisture in the terminals can affect safe use and correct functioning If the IPC or connecting leads are damaged then the IPC will need to be replaced Verify the IPC operation by momentarily connecting a known 230VAC voltage to each combination of phase pairs until all 6 Indicators have been illuminated The battery can be tested by holding the MEM button for 4 seconds If 6 LEDs light then the batteries are good Use only alkaline batteries If storing for long periods remove batteries in case of leakage Accessaries Part Number Description IP 01 1020 Set of 3 Crocodile Clips IP 01 1030 Set of 3 Retractable Hook Probes IP 01 1040 Set of 3 Insulation Piercing Probes Technical Assistance MPS ADVANCE ELECTRONIC TECHNOLOGY S L Urb La Vista C Tr bol 4 6 E 29639 Benalm dena M laga Espa a Tel 34 952 56 56 88 info mpsaet com www mpsaet com General specifications Model Input Voltage 3 phase to phase inputs L1 L2 amp L3 440 V AC max 600V DC max DC BUS Voltage 280 600V DC Phase load 8 5 mA maximum per phase Advance Electronic Technology Carrier Frequency 5 to 20Khz Operating Environment 0 C to 40 C at lt 80 R H Indoor and dry outdoor IP40 Altitude 2000 m 6561 ft max Power 2 x 1 5V LR6 AAAlkaline Battery Only Dimensions Enclosure 119 L x 79 W
3. When testing is complete clear memory to put the IPC into standby mode and save battery power If any or all of the outputs are not functioning properly then the Invertor board or IPM will need to be replaced Operation The IPC will record and display any valid signals it detects with LED and an audible beep Valid signals are recorded in memory and will remain until cleared Following 4 seconds of no activity the IPC will notify of a start up sequence having been detected by sounding a single IPC 307 Cd AC Inverter Phase Checker short audible beep every 4 seconds Corresponding LEDs will flash indicative of valid signals sensed This will continue for 18 minutes after which the memory will be cleared and the IPC enters standby mode Memory Inverter start up Sequences are often very short in duration only a second or more So the IPC stores valid signals in memory for later observation Memory is recalled at any time by momentarily pressing the MEM button to display which signals have been detected All 6 LEDs constantly lit indicated a test pass Holding the MEM switch for 4 seconds or longer will clear memory and place the IPC in standby mode The memory must be cleared before initiating any test or repeat test Magnetic Base gay Example of connecting the IPC 307 The IPC 307 has a strong magnetic base for mounting conveniently on to steel condenser housings to the Inverter Compressor feed Terminals Compressors Co
4. be made by properly trained professional persons familiar with the hazards involved When using the test leads keep your fingers behind the finger guards Do not allow conductors of probes to come into contact with other components or any part of the case or metal parts Do not make or disconnect circuits while live This is dangerous and may cause permanent damage to components The IPC has a strong magnetic base for mounting conveniently on to steel condenser housings The engineer must be sure the mounting is secure before powering up Protect the Inverter Checker against water moisture condensation and precipitation If the IPC or connecting leads are damaged they must be replaced Do not apply more than the rated voltage as marked on the IPC No serviceable parts inside Do not open the IPC Casing Operate only with battery cover fitted Limit the time the IPC is connected to outputs of continuous activity to 10 minutes Rest for 10 minutes before repeat test Inverter Information Testing The inverter uses a rectifier to convert the incoming alternating current AC to direct current DC and then switches the 6 Warning transistors in a sequence to produce AC of a desired frequency The variable frequency AC drives the compressor To avoid electric shock or injury or damage to the IPC always disconnect power supplies before making or When an inverter system starts up It is common for there to be a delay of typically two to th
5. his only occurs for a second or so The IPC will notify of a start up sequence having been detected by sounding a single short audible beep every 4 seconds corresponding LEDs will flash indicative of valid signals sensed X J a nee FF ea i ae JEn a Press the MEM button to recall test result All 6 LEDs must light Hold MEM to clear memory for re testing If one AC IN RECTIFI DC OUTPUT AC MOTOR CATION VOLTAGE TRANSISTORS or more LEDs are not lit check probe connections and repeat test Introduction to the IPC 307 The IPC functions to identify inverter faults when a problem arises such as compressor over current protection and shut Conclusion down It senses and measures valid switching operation of the 6 output transistors in inverter systems A sequence in Correct Function Inverter Outputs all 6 LEDs must light which all 6 transistors switch both on and off is indicative of correct operation The IPC is connected to the inverter l instead of the compressor and automatically monitors the inverter output Faulty Output one more or all of the LEDs do not light Faulty Output one or more LEDs are constantly on Battery Powered The IPC remains in standby mode and will start automatically when inverter activity is sensed on the L1 2 amp 3 inputs or when the MEM button is pressed Virtually no power is consumed while in standby The battery can be tested by holding the MEM button for 4 seconds If 6 LEDs light then the batteries are good
6. mpressors can fail with insulation breakdown between motor windings or down to earth It is advised to carry out an electrical insulation test to earth and a resistance test between each winding of the compressor in accordance with manufacturer s data prior to reconnecting 2 Year Warranty This product has been fully tested and is certified to be free of any faults Provided it is operated transported and stored in a professional manner and in accordance with the instructions it will give long and reliable service If any fault develops check first the servicing section of this leaflet lf the product fails within 2 years of purchase due to a defect in either materials or manufacture it will be replaced or repaired by the manufacturer provided it can be clearly shown that it has been operated maintained and used as shown in the instructions No liability can be accepted under any circumstances for any indirect incidental or consequential damages or losses including data arising from the use of this product This warranty does not cover batteries damage from neglect misuse contamination alteration accident or abnormal conditions of operation or handling including failures caused by use outside of the product s specifications or normal wear and tear of mechanical components Warranty will be void with evidence into opening or tampering with the casings This warranty covers the original purchaser only and is not transferable
7. ree minutes before the output disconnecting connections Wait three minutes for stored charge in capacitors DC Voltage to safely is enabled and the duration of the output switching sequence that follows may only last for a second or more discharge The sequence is terminated once the inverter senses there is no compressor loading This Inverter Phase test must be carried out with the compressor disconnected from the Inverter Board In some cases the phase sequence might be repeated following a further delay Also following a fault some systems will Disconnect the 3 phases supplying the compressor require a resetting action of some kind 3 PHASE INVERTER Connect L1 L2 and L3 of the IPC to the 3 phases output from the inverter board sometimes designated U V W There are various ways of connecting the Inverter Phase Checker depending on the type and accessibility of the terminals The Engineer must ensure that suitable and secure connections are correctly made before switch on After all connections are safely made switch on the power Clear the IPC 307 memory and check battery condition by pressing and holding the MEM switch for 4 seconds until a beep is heard The 6 LEDS will light in sequence Release the switch Configure the system to call for cooling As soon as the inverter initiates a start up sequence corresponding LEDs will blink in a sequence not indicative of rotation direction and an audible beep will sound Normally t
