    4.1.3 Fuses Use a 6.3-10A Fuse for protection of the auxiliary circuits. For protection of the power unit, use a 350A fuse in the Battery Positive connection. For special applications or requirements these values can be reduced. For Safety reasons, we recommend the use of protected fuses in order to prevent the spread of fused particles should the fuse blow.

  • Page 13: Wirings: Power Cables

    The COMBIAC0 module should only be connected to a traction battery. Do not use converters outputs or power supplies. For special applications please contact the nearest Zapi Service Centre. Do not connect the controller to a battery with a nominal voltage different than the value indicated on the controller label.
  • Page 14 Wrong Layout: Module Module Module The red lines are can wires. The black boxes are different modules, for example traction controller, pump controller and display connected by canbus. The black lines are the power cables. This is apparently a good layout, but can bring to errors in the can line. The best solution depends on the type of nodes (modules) connected in the network.

Here is the ALARMS list: 1) “CAPACITOR CHARGE” Follows the charging capacitor system: When the key is switched ON, the inverter tries to charge the power capacitors through a power resistance, and check if the capacitor are charged within a timeout.
  • Page 62 B) If the alarm occurs during motor running, check: Motor connections If motor phases windings/cables have leakages towards truck frame That the LC power contact closer properly, with a good contact If no problem are found on the motors, the problem is inside the controller.
  • Page 63 CNA#12 and –BATT. B) The driver circuit is damaged in the controller, which has to be replaced. C) The wires to the LC coil are interrupted or not connected, so check the coil related harness. 7) “CONTACTOR DRIVER” Cause: The LC coil driver is not able to drive the load. The device itself or its driving circuit is damaged.
  • Page 64 13) “LOGIC FAILURE #1” This fault is displayed when the controller detects an overvoltage or undervoltage condition. Overvoltage threshold is 35V, undervoltage threshold is 9,5V in the 24V controller. In 48V controller overvoltage threshold is 65V, undervoltage threshold is 9,5V.

  • Page 66 low value, the problem is inside the controller and the Smart Driver is probably damaged. 23) “KEYOFF SHORTED” Cause: This fault is displayed when the controller detects a low logic level of Key-Off signal during Start-Up diagnosis. Troubleshooting: It is very likely the fault is due to an under voltage, so it is suggested to check: A) Key input signal down-going pulses (below under voltage threshold) due to external loads, like DC/DC converters starting-up, relays or contactor...
  • Page 67 Motor connections If motor windings/cables have leakages towards truck frame That the LC power contact closer properly, with a good contact If no problem are found on the motors, the problem is inside the controller. 27) “PUMP VMN HIGH” Cause: This test is carried out when the pump motor is turning (pwm applied).
  • Page 68 32) “EMERGENCY” Cause: The voltage on A3 is different than +Vbatt. Troubleshooting: If A3 is correctly connected to +Vbatt. If the fuse on A3 is not damaged. 33) “FLASH CHECKSUM” Cause: The software was not correctly written into the flash memory or the flash memory is damaged.

  • Page 72 6) “BATTERY LOW” Cause: It occurs when the battery charge is calculated being less than or equal to 10% of the full charge and the BATTERY CHECK setting is other than 0 (refer to SET OPTION menu). Troubleshooting: Get the battery charged. If it doesn’t work, measure with a voltmeter the battery voltage and compare it with the value in the BATTERY VOLTAGE parameter.

  • Page 74 B) If the fault is present when the controller drives the outputs, the problem is located in the harness and in the coils. 19) “EV1/5 DRIVER SHORTED” Cause: Electrovalve EV1 or EV2 driver is shorted. Troubleshooting: Check if there is a short or a low impedence between the negative of one of those coils and –BATT.
  • Page 75 The EVP2 valve driver is not able to drive the load (cannot close). Troubleshooting: The device or its driving circuit is damaged, replace the controller. 26) “PUMP I NO ZERO” Cause: In standby condition (pump motor not driven), the feedback coming from the current sensor in the pump chopper gives a value out of a permitted range, because the pump current is not zero.
  • Page 76 The device or its driving circuit is damaged, replace the controller. 32) “CONT. DRV. EV2” Cause: The EV2 valve driver is not able to drive the load (cannot close). Troubleshooting: The device or its driving circuit is damaged, replace the controller. 33) “CONT.
