Volvo Penta Engine Fault Code When a malfunction has occurred and the diagnostic system has generated one or more fault codes, these are read out differently depending on the equipment used. Please refer to “Fault code messages”. If the system indicates that a fault code has been set: 1 Cut engine speed to idle, or shut the Volvo engine off. 2 For DCU/DU Read the fault code from the display, please refer to Reading fault codes via the DCU or Reading fault codes via the DU. For CIU press the diagnostic button and read the fault code, by observing the flashing of the diagnostic lamp. Refer to Reading fault codes via the diagnostic lamp, CIU. 3 Look up the fault code in the Fault Code Register chapter and take the recommended measures. Reading fault codes via the DU (Display Unit) Depending on the severity of the fault the text, either WARNING! or ALARM STOP (a buzzer sounds) will be shown on the display 1 Press any button to come to the fault list. The f...

Normally Closed-(Symbol N.C.) - As applied to a magnetically operated device such as a valve or the contacts of a relay, Normally Closed indicates that the valve or relay contacts are closed when no power is supplied to the operating magnet. Normally Open- (Symbol N.O.) - As applied to a magnetically operated device such as a valve or the contacts of a relay, Normally Open indicates that the valve or the relay contacts are open when no power is supplied to the operating magnet. Ohm - The unit of measure of electrical resistance. One ohm of resistance will allow a current of one ampere to flow with an applied potential of one volt. Ohmmeter - An instrument for measuring electrical resistance. Ohm's Law - A fundamental law expressing the relationship between voltage, current and resistance in electrical circuits. The law states that E = IR or voltage is equal to current times resistance. Open Circuit - 1) A circuit that does not provide a complete path for the...

Alternating Current  - Electrical current which repeatedly varies from zero to a positive maximum value to zero to a negative maximum value and back to zero at a periodic rate. Since the applied voltage continually reverses polarity, the resultant current flow alternates in direction within the circuit. AMP  - An abbreviation for the term Ampere. Ampere  - The unit of measure of electrical current flow. One ampere of current will flow when one volt of electrical potential is applied across one ohm of resistance. Auto-Transformer  - A transformer of single coil construction in which both the primary and secondary connections are made on the same coil but at different taps. B-  - Symbol used to designate the negative polarity of a D.C. voltage supply. B+  - Symbol used to designate the positive polarity of a D.C. voltage supply. Capacitance  - The property of a device which resists changes in voltage. In an A.C. circuit, a capacitive load ...

Calibration and Settings of Volvo Power Generator Engine Engine: TAD1640GE, TAD1641GE, TAD1642GE,etc Inverted regulator mode Select if droop value is to be active. Alternative modes: “No droop value” or “Variable   droop value” Preset mode: “Fixed droop value” Regulator mode Select if droop value is active. Alternative modes: “Off” or “No” Preset mode: ”No” Primary regulator mode Selects the regulator to be used when the regulator   contact is closed. Alternative modes: ”Isochronous” or ”Droop value” Preset mode: ”Isochronous” Regulator gradient Determines the droop value to be used (gradient) Min. value: 10 Nm/revolution Preset value: 25 Nm/revolution Max. value: 128 Nm/revolution Stop function Preset mode: ”Stop” CIU stop function The CIU unit stop signal is energized during “Operations”   or “Stop”. Preset mode: ”Stop” Lamp test This parameter determines if a lamp test is to be performed   when the system is...
