INTRODUCTION

The R-200A Controller incorporates the generator control circuitry, the ignition coil driver circuitry and the interface circuitry to an external governor driver.

The R-200A Controller can control a;

•4-cylinder, 1.6L, 1800 rpm or 3600 rpm engine

•4-cylinder, 2.4L, 1800 rpm or 3600 rpm engine

•6-cylinder, 4.2L, 1800 rpm engine (with separate ignition coil driver)

The R-200A controller will monitor the utility voltage to determine if stand-by power is required. Should the utility voltage fail, the unit will start and run, detaching from the utility and supplying the customer load from the generator.

Both the 1.6L and 2.4L engines use a magnetic pickup on the flywheel gear to provide speed informa- tion. A cam sensor is used to provide engine position information. Each engine uses two coil drivers in a waste spark coil pack for ignition. With a waste spark coil, each high-voltage coil output is connected to two spark plugs resulting in each spark plug being fired during both the compression and exhaust cycle.

The 4.2L engine uses a magnetic pickup on the fly- wheel gear to provide speed information. A cam sen- sor and a crankshaft sensor provide information to a separate ignition coil driver that fires each spark plug independently.

The above generators are configured, at the factory, to use either LP Vapor or Natural Gas (NG). The gov- ernor gains have been pre-set and are not adjustable. The output frequency of the generator main alterna- tor is 60Hz.

The controller PCB, located on the inside door of the R-200A, may have one of several part numbers. Early 1.6L units will have part number 0G1505A. Early 2.4L units will have part number 0G1505B. Later units have part number 0G1303A for 1800 rpm or, 0G1303B for 3600 rpm. The 0G1303B is a suitable replacement for the 0G1505A and 0G1505B. In later units, or if the engine has emission controls, part number 0G1303C is used for 1800 rpm and 0G1303D is used for 3600 rpm. The latest versions include 30kW, 3600 rpm, 1.6L control and 18kW, 1800 rpm, 1.6L control. Part number 0G1303E is used for 1800 rpm and 0G1303F is used for 3600 rpm. The 0G1303C or 0G1303E will work in place of 0G1303A. The 0G1303D or 0G1303F will work in place of 0G1303B, 0G1505A or 0G1505B.

The addition of the 4.2L engine required creation of a new series of controller (see Figure 2). This control- ler is part number 0G3958C for 1800 rpm units and 0G3958D for 3600 rpm units. All previous part num- bers are replacable with these new controllers.

CONTROL BOARD DIP SWITCH & JUMPER SETTINGS

The Switch "ON" position location is marked on the DIP switch housing (see Figures 1 and 2.) To activate the DIP Switch settings place the AUTO/OFF/MANUAL switch in the OFF Mode, make the DIP switch chang- es and then push and hold the Set Exercise Switch for five seconds.

DIP Switch Position 1: Reserved for future use. The position of this DIP Switch does not affect generator operation.

DIP Switch Position 2: Selects the type of transfer switch to be used with the generator. When an "HS" or RTS-type transfer switch is used (ATS Mode) this DIP Switch should be in the OFF Position. When a W-type transfer switch is used (GTS Mode) the generator 2-wire start inputs can be used to control the gen- erator operation. The 2-wire start inputs are labeled as 178 and 183 on the wiring terminals inside the generator's customer connection panel.

DIP Switch Position 3: Selects the engine operating speed in exercise mode.

DIP Switch Position 4: Selects the type of Fuel used by the generator. The fuel regulator must also be con- figured for the correct fuel type.

DIP Switch Position 5: Selects the engine displace- ment when Switch Position 7 is OFF. This position is ignored when Switch Position 7 is ON.

DIP Switch Position 6: Selects the alternator kW rating for the 2.4L at 3600 rpm and the 4.2L at 1800 rpm. The position of this DIP switch does not affect generator operation for the 1.6L, or the 1800 rpm 2.4L.

DIP Switch Position 7: Selects 4.2L displacement when ON. When OFF, Switch Position 5 selects dis- placement.

DIP Switch Position 8: Reserved for future use. The position of this DIP switch does not affect generator operation.

	Switch OFF	Switch ON
Position 1	Reserved	Reserved
Position 2	ATS Mode	GTS Mode
Position 3	Low Speed Exercise	Normal Speed Exercise
Position 4	LP Vapor Fuel (LP)	Natural Gas Fuel (NG)

Position 6	45kW (2.4L, 3600 rpm and	35kW (2.4L, 3600 rpm and
	4.2L, 1800 rpm)	4.2L, 1800 rpm)
Position 7	1.6L, 2.4L	4.2L
Position 8	Reserved	Reserved
