OF VOLTAGE REGULATORS

DESCRIPTION

The Adapter RTP9005S is used for diagnostics of alternator voltage regulators.
The Adapter RTP9005S simulates control signals for the tested voltage regulator. It contains integrated physical interfaces and program protocols of all actually existing voltage regulators.
Voltage regulators can be tested:

• directly in the car with the alternator assembly
• on the test bench in assembly with the alternator dismounted from the car
• separately from the alternator
  Adapter RTP9005S additional features: it can be used as PWM generator or as an oscillograph.
  The adapter has additional functions: a PWM generator and an oscillograph.
  The device’s control is easy and user-friendly, the indication is very convenient due to the color 4.3” TFT display.
  Software is to be updated through USB port if new protocols appear.
  Contemporary voltage regulators (alternators) with COM (LIN/BSS) terminal cannot be properly tested without such diagnostic adapter.
  The diagram below provided by the company Bosh illustrates that these types of voltage regulators oust the others and can be mounted in low-cost cars by now:

STEP-BY-STEP INSTRUCTION

Adapter RTP9005S tests the alternator assembly (the alternator assembled with the voltage regulator) directly in the car or separately the voltage regulator only. Both variants  are considered further.
6.1. Testing of the alternator assembly in the car
Testing in the car is carried out with the help of four-wire cable (Fig. 2). The adapter is connected to the car electrical system according to the color marking described in the  point 3.2. For accurate voltage measuring, the adapter’s negative wire should be connected to the corresponding battery terminal. The testing is conducted in the following  sequence:

• Connect the adapter to the car electrical system.
• Start the car engine and wait until it operates steady at idle.
• Check the voltage value on the display. If the value is lower than the nominal one, check the alternator belt tension.
• Change the alternator voltage value (if the alternator model implies changing the value). The voltage on the adapter should coincide with the set one. Otherwise, the  voltage regulator should be tested separately from the alternator.
• Check the alternator operation under average rotation frequency of the crankshaft when battery charge is full. Increase load on the alternator by turning on the  headlights and other lighting devices. FR value should change as well. If voltage is within the norm, the voltage regulator is faultless. If voltage is above or below the  norm, check the voltage regulator and replace it if necessary. If voltage is out of the norm, the alternator should be dismounted from the car for repair.
• Connect the control terminal of the alternator back to the car.
• Check the adapter’s indication. If the alternator output voltage value exceeds the norm, check the signal in data transmission line (“LIN”, “CAN”, “K-LINE”) in the  mode of oscillograph.
• Stop the engine.
• Disconnect the adapter terminals from the car.
  WARNING! Testing must be carried out in the premises with combined extract and input ventilation or fume offtake system. Otherwise, testing must be conducted outdoors.

6.2 Testing of the voltage regulator separately from the alternator
Testing of the voltage regulator separately from the alternator is conducted with the help of ninewire cable (Fig. 3). The device is connected to the voltage regulator according to the color marking described in the point 3.2 and Appendix 2. The testing is conducted in the following sequence:

• Connect the adapter to power supply through USB connector.
• Select the needed option in the menu with the buttons “⇧”, “⇩”.
• Connect all the needed voltage regulator outputs. Tips with the most common types of connectors will appear on the screen.
• Enter the testing mode with the button “⏎”.
• Follow the display indication and adjust voltage with the buttons “⇧”, “⇩”. If the voltage regulator is faultless, the measured voltage should change for “B+” when  changing the set voltage; and there should be no errors in COM voltage regulators.
• Exit the testing mode with the button “⏎”.

6.3 “PWM” mode (PWM generator)

In this mode:

• Select the option in the adapter’s menu with the buttons “⇧”, “⇩”.
• Enter the testing mode with the button “⏎”.
• Connect the wires “GC” and “-” from the adapter’s outputs to the controlled device.
• To change the duty cycle, press the duty cycle set area on the screen. The numbers will be lightened by another color. Set the needed duty cycle value with the buttons “⇧”, “⇩”.
• To change the frequency, press the frequency set area on the display. The numbers will be lightened by another color. Set the needed frequency value with the buttons “⇧”, “⇩”.
• Exit the testing mode with the button “⏎”. Disconnect the wires.

6.4 “Oscillograph” mode
In this mode connection to the source of analized signal is carried out with the help of the fourcore cable using the wires with black (negative) and yellow (GC) color marking.

• Select the option in the adapter’s menu with the buttons “⇧”, “⇩”.
• Enter the testing mode with the button “⏎”.
• Connect the wires “GC” and “-” from the adapter’s output to the signal source.

SAFETY MEASURES WHEN WORKING WITH RTP9005S

In order to avoid possible electric shock or injury as well as damage of the adapter or a tested equipment, the following instructions should be strictly observed:

• Make sure that the measuring clamp does not have insulation damage or bare metal spots. Make sure that the clamp is not damaged. In case of obvious damage, change it for a new one before using the adapter.

• In order to avoid possible electric shock or injury as well as damage of the adapter, do not apply voltage exceeding 20V to the adapter outputs or between the earth and any of the outputs.

• When measuring, try to connect outputs correctly, especially, “B-“. The device has all kinds of protection against emergency situations, however, not all voltage regulators have such protection.
  If you have questions about how to connect a voltage regulator that is not mentioned in actual user manual, please contact MSG Equipment customer support.

• Do not store or use the adapter in places of high temperature, humidity, danger of explosion or fire, intense magnetic field. As a result of dampness, operation of the  device may deteriorate.

• To avoid damage or failure of the adapter, do not make changes in your discretion in the electrical diagram of the device. In case of failure, please contact the  manufacturer or the trade representative.

• To clean the surface of the adapter, use a soft cloth and spray for cleaning monitor screens. To avoid corrosion, damage or failure of the device, do not use abrasives and  solvents.
