Information:


De-energize generator set starting circuit before making repairs, connecting test instruments or removing or making connections to or within the voltage regulator. Dangerous voltages are present at the voltage regulator terminal boards and within the voltage regulator when the generator set is running. These include the sensing voltage, power to the voltage regulator and the voltage regulator output. Accidental contact with live conductors could result in serious electrical shock or electrocution.
Regulator sensing circuit must never be opened while power is applied to the regulator input power terminals. Loss of sensing voltage will result in maximum regulator output. The voltage regulator dc output (terminals F+ and F-) must never be opened during operation. To do so will produce inductive arcing that could destroy the exciter or voltage regulator. Therefore, never place circuit breaker contacts or voltage shutdown switch in he exciter field circuit.
Megger or high potential test equipment must not be used when testing the voltage regulator. Disconnect interconnecting conductors between the generator and voltage regulator when testing generator or exciter with megger or high potential test equipment. The high voltage developed by megger or high potential test equipment will destroy the solid state components within the voltage regulator.
Power output125 V dc 10 amperes, maximum continuous output; 180 V dc, 15 A one minute field forcing where regulator is constructed for 240 V ac input.Input powerSingle phase, 50 to 180 Hz, 240 V ac 10%.SensingStandard regulators are constructed for three phase 100 V ac to 600 V ac sensing. Special voltage or frequency available as optional feature. V/Hz sensing is standard for underfrequency.Voltage adjustment range 10% standard. Wide range voltage adjust available as an optional accessory.Field resistance12.5 ohm minimum; 200 ohm maximum for optional 125 V dc regulator.Paralleling1 A for 6% droop or 5 A for 6% droop on current transformer. For 1 A connect to terminals CT and CT1; for 5 A connect to terminal CT and CT5. Factory adjusted 4% droop.Fuse15 A maximum, ABC type fuse for voltage regulator protection.Underfrequency protectionThe underfrequency limit (UFL) circuit will provide underfrequency protection by reducing voltage in proportion to frequency as frequency is decreased. The UFL operational threshold where limiting starts is as follows: Standard for use with generator driven by turbocharged engine 59.5 Hz for 60 Hz system, 49.5 Hz for 50 Hz system.Regulator accuracyVoltage regulation is maintained within 1/2 percent over full range of generator loading and for generator speed variations of up to 5 percent.Regulator responseLess than 17 milliseconds. Thermal stability - Less than 1/2 percent for 40 degrees change in ambient temperature.Operating temperature-40°C (-40.0°F) to 60°C (140.0°F).Storage temperature-60°C (-76.0°F) to 85°C (185.0°F).Power dissipationLess than 35 W at maximum continuous rating during single generator operation; less than 45 W at maximum continuous rating during parallel generator operation.ShockTested to withstand up to 20 g's in each axis. Vibration - Tested to withstand 1.2 g's from 6 to 26 Hz; 0.32 in. double amplitude from 26 to 52 Hz; 5 g's from 53 to 150
