How to Check the GTS MAPLA – additional information
Warning: At first observe strictly the safety information at the operating instructions. Beware of high voltage direct current up to 380VDC!
The following instruction refers to the old MAPLA system. If you have an INT = iMAPLA system it is recommended to read out the MMI error flash code (MMI indications) at first. The troubleshooting of an iMAPLA system is quite similar to the old MAPLA system.
First see in the operating instructions at page 75 – 4.9 Troubleshooting
If an overload condition occurs (LED No. 5 lights): For further information you look in the operating instructions at page 75 (troubleshooting procedure). An overload condition occurs, if the magnet plate is oversized or damaged by taking a too high magnet current. At first check the resistance of the magnet plate. Ensure that the magnet plate is unplugged. Check the result with the following resistance table:

Magnet plate resistance for GTS systems (actual MAPLA)
If the resistance is undersized, take a smaller magnet plate (with a higher resistance) and connect it to the generator system. Check the System again and measure the magnet current. Note: A warm plate has a higher resistance than a plate at 20°C / 68°F.
If the resistance is normal or higher than allowed, check the magnet plate with the high voltage megaohmmeter. Ensure that the magnet plate is unplugged from the machine. If the resistance between the case and the active conductor is less than 50 KiloOhms the magnet plate is damaged. The rated insulation resistance of a new plate is higher than 500 KiloOhms.
If an short circuit condition occurs (LED No. 5 flashes): For further information you look in the operating instructions at page 75 (troubleshooting procedure). A to high current (short current) causes a cut-off of the generator immediately. This is necessary to protect the electronic, the generator and the cables against overloads. If it is the first time you start up the system, check the pin assignment at output for magnet plate.

Note: To measure the insulation resistance by an insulation-monitor (optional for MAPLAs available)
the green/yellow wire should be connected to the magnet plate! Next check the magnet plate resistance (see above at overload condition). Further you have to check the power cable to the magnet plate against shorts and breaks or insulation errors. Perform a reset of the generator/system. If the fault occurs again, unplug the magnet power connector at the generator (only the connection to the magnet plate) and reset the system again. Start the generator and activate the magnet with the joystick button. If the LED No. 4 lights after a few seconds the MAPLA system is alright. If already the error exists (LED No. 5 flashes), the electronic has an internal fault. Change the electronic case at the generator and try again. You can check the power unit and the rectifier with a simple circuit analyzer (see below at page 2).
How to check the power unit (amplifier) and the rectifier in the electronic case: To test the power modules of the MAPLA take a rectifier analyzer to check the forward voltage of the discrete diodes. The description how to contact the MAPLA is written at page 7 and 8. At first you have to disconnect all connectors from the generator, the regulator and the magnet plate.

The forward voltage of the rectifier/diode is approx. 0,35V to 0,7V. If you have a breakdown of one diode, the forward voltage in both directions is 0,0V and so the power-module is damaged.
No power supply voltage for MMI available: Defect characteristics: The generator is running and active but the power supply LED No.1
at the MMI is off (does not light). Check the generator speed. The rated speed range of the generator is written in the default value table (see below at page 6). Build sizes of 132 need a minimum of 2800 rpm. Build sizes of 160 need a minimum of 2200 rpm. Check the exciter fuse, connected in row to the exciter line PIN1/F1 connected to the voltage regulators in the top of the case. Therefore you need only to open the case of the switch-box. If the exciter fuse is blown, it is recommended to change the voltage regulator and the fuse at the same time. GTS specifies to use a “Multicomp 3A slow blow 6.3x32mm 250V” type.

Check the connections between the regulator, the generator and the electronic case. Check the MMI cable. Test the connection of every wire from the electronic case to the MMI. Check also the fuse of the MMI in the electronic case (see description below at page 7 and 8). Note: do not twist the fuse, only twist the cover to release the fuse Check the generator main winding resistance with an Ohmmeter. For it take the connection plan of the next picture (see below) and the default value table at page 6. If one of the results is out of the range, the generator could be damaged. It is also important, to check the insulation resistance of the stator main windings with a high voltage megohmmeter. Therefore you have to unplug the connector between the generator and the controller box. Ensure that you have no connection to the electronic case. The pin-connection of the generator is described at the two pictures below. Measure the insulation resistance with 500V (megohmmeter) between all connections and the case of the generator. If the resistance is less than 50KiloOhms the generator is damaged. The generator could also have lost the remanence (retentivity). If there is no rest of magnetism in the generator, the remanence voltage of the generator at idle running is less than 10VAC. This case causes that the regulator could not supply the exciting winding with current to build up the required magnetic field. Therefore the output voltage at the main machine is too low. You can check the remanence voltage of the generator. At first ensure that the generator is not rotating (stop the engine). Then you have to disconnect the connection of the generator to the electronic case. Ensure, that the regulator is disconnected. Take a voltmeter and set it to VAC-mode. Measure the voltage between the three phases U / V / W while you run the generator at the rated speed. The default remanence voltage range is written in table at page 6.

If the voltage is less than 10VAC, it is possible to rebuild the remanence. Stop the generator and take a 12V DC-power supply (approx. 10W power). Connect the pin +F1 with the +12V conductor and the –F2 pin with the ground (GND) conductor of the supply. A current of approx. 0,5A rebuilds the remanence in the generator (if it’s possible drive the generator with approx. 1500rpm). Supply the generator with this current only for 2-3 seconds. Following, check the remanence voltage between the phases again while the exciting current is again zero (no regulator connected).

Not enough output voltage at the magnet plate: Defect characteristics: The generator is running and the output voltage at the magnet
plate is less than 200 VDC (result: not enough power). Check the generator speed. If the speed is less than the rated values in the default value table (see below) the generator is not able to supply the electronic with the required power. Check the connections between the regulator, the generator and the electronic case. Check the exciting voltage at ST1 between 1F1 & 1F2 (red and grey wire) with a voltmeter set to mode VDC. Note, that the voltmeter is able to measure “true-RMS”-voltages. Check the result with the default value table (see below). If the voltage is too high and the exciting current is higher than 2,0A the generator could be damaged (one of the rotating rectifiers). Next check the generator main winding resistance with an Ohmmeter. For it take the connection plan (see above) and the default value table at page 6. If one of the results is out of the range, the generator could be damaged. It is also able that one of the rotating diode in the generator is damaged. This causes a loss of exciting field (rotor) in the main machine of the generator. So we have only a weak magnetic field, which could not induce the rated voltage at the stator winding (power loss). In this case you can also check the exciting current of the regulator. If you have in a no load mode (magnet off) at the rated speed a low output voltage and the exciting current of the regulator is higher than 2,0ADC then it could be possible, that the exciter or one of the rectifier inside of the generator is damaged. To measure the exciting current, see the description at page 6.
Too high output voltage at the magnet plate: Defect characteristics: The generator rotating at rated speed generates a too high output voltage
to the magnet plate. The static voltage is higher than 250 Volt DC. (Note: The voltage to fast magnetisation is up to 280 Volt DC for
only 3-5 seconds after you have switched-on the magnet. The too high output voltage for a long time causes also a overload condition of the MAPLA System displayed with LED no. 5 at the MMI )
Check the impulse excitation interface ST2 (white wires) to the regulator connected to the MAPLA electronic. By a contact fault, the output voltage of the generator is constant higher than 275Volt DC. Check the voltage between the three yellow wires at the regulator connection ST1. Between every conductor you have to measure the voltage of the three phases from the generator. Check the results with the default value table at page 6. If there is one phase missing, the measured actual value of the regulator is wrong. So the regulator set a too high exciting current to the generator. This causes the over voltage of the system.

Slow system / long drop time: Defect characteristics: The generator is rotating at rated speed but the load at the magnet plate
falls down very slowly. This causes a long cycle time.
First check the voltage at magnet plate. Ensure that the Mode-Switch is in A-Position (normal mode). After switch on (push the joystick-button) the magnet voltage should be 280VDC for 2-3 seconds. This phase is called fast-magnetisation (fast pick-up) with impact excitation. While the magnet is on the output voltage to the magnet should be 230VDC constant should be after 3 seconds (rated voltage of the magnet). If the magnet voltage is never 280VDC for a short time after switch on, check the voltage regulator contacts an also the connection of the interface ST2 (see pictures at page 7 and 8). In the drop phase (material falls down) the output voltage at the magnet should be negative for several times. The polarity of the output voltage is changed 5 times so achieve the elimination of the rest of magnetism at the magnet plate. If the discharger unit is damaged, the electronic box could not change the output voltage. This causes a slow drop cycle (takes a long time). To check the discharger resistances (see the pictures below) take a normal ohmmeter and check the resistance values.

the exciting voltage at ST1 (see connection plan at page 9 and 10). The current is calculated by voltage / resistance (divide).

1 Power supply voltage for MMI available The system is ON and ready for operation – the generator is running. 2 Magnet plate is on ("lifting") This LED remains on while the magnet plate is in the on state. If the magnet plate is switched off, i.e. the load is thrown off, this LED goes out. 3 Fast demagnetization in progress (“fast drop”) 3 (fast „throwing off“ only in normal mode / A-Mode) The LED is on during automatic fast demagnetization. The LED goes out after the demagnetization has been finished completely. This mode is disabled if inching mode* (optional mode B) is selected. 4 Open magnet connection / Data interface fault LED on: Open magnet connection / Interruption The LED light continues, if the connecting cable of the magnet plate is either not plugged in or interrupted. LED flashes: Data interface error The LED flashes, if a communication error has occurred on the data interface between MAPLA and MMI. Check the MMI data cable against electrical contact problems. 5 Overload / System failure LED on: Overload (magnet current limiter at INT-System active) The LED is on, if the connected magnet plate is oversized for the MAPLA system. In some cases the magnet plate could be damaged internally. At the new INT-System, the magnet current limiter is active. The magnet current is limited to the max. allowed value. The LED could also be light, if a very cold magnet is connected. After a few minutes while operation, the LED should be off. Otherwise the magnet should be checked. LED flashes: System failure (at older non INT-Systems: Short circuit) This LED flashes, if at an INT-System a system failure has occurred. To find out the exactly causation of this fault, a flash-code could be displayed at the 100%-LED and verified with a separate flash-code table. At older systems (non INT), the flashing LED means, you have a general short circuit. The magnet was switched off (cut-off) immediately. The problem should be checked by an electricity specialist. To reset the fault, an engine stop is required. 6 Underspeed / Overspeed LED on: Underspeed generator The LED is on, if the generator operates at underspeed and thus may no longer be able to realize its full performance (reduced voltage). LED flashes: Overspeed generator Flashing of this LED indicates that the generator operates at overspeed. The system / magnet is blocked to switch on again. May you need a reset of the system (stop engine). 7 Duty ratio of the magnet plate in percent The duty ratio of the magnet plate is the ratio between on-period and off-period. To protect the magnet plate (against over temperatures), the duty ratio should be less than 80%. Check also the max. allowed value for your used magnet. If the 100%-LED is flashing, it is required to take a break period! 4 + 5 + 6 LED flashing Insulation monitor alert The insulation monitor (optional) has detected an insulation error between the magnet plate case and the active conductor (+/-) of the MAPLA system. If these LEDs are flashing the resistance is less than 25 KiloOhms. It is required to check the system against insulation faults. At INT-Systems, the magnet is blocked to switch on again (reset required).
4 + 5 + 6 LED on + 7(100%) LED flashes Over temperature error of electronic / generator As long as this error is indicated, the magnet plate could not be switched on again after having thrown off the load. Once temperature of generator and electronic is within the tolerance limits again, the indicator will go out automatically. It is recommended to cool down the system while engine is running in idle mode. Check the system against dust and a covered or damaged generator fan!
