1.2.4.1 Notes on the Proportional Amplifier

Note!

The proportional amplifier may only be removed when made dead.

On delivery, two adjustment protocols incl. the preset values and the inserted jumpersare attached to the proportional amplifier (to be found in the inside door pocket).

In case of a new installation, the jumpers are to be checked -- and, if required, to be cor-rected -- in accordance with this protocol.

In the normal case, the values to be adjusted have been preset by the factory, providedthat the information on the solenoid valves used was known before delivery of the equip-ment.

Amplifier Box



These values as well as the jumpers are then recorded in the adjustment protocol.If the values preset at the works should not coincide with the indicated values of the so-lenoid valves used, these must be re--adjusted by the service technician as described inthe following.

These values are to be written into the adjustment protocols, and one of them is to besent to the Raytheon Marine Service Department.

1.2.4.2 Zero Current and Rated Current Adjustment-- Set the steering mode selector to FU-- Connect voltmeter (DC) to L1.18 () and L1.19 (+)-- Should the jumpers B3, B6, B12, B14 and B16 not be inserted, these are to be

2.2.1.1 Setpoint SpecificationThe solenoid current is adjusted by specifying a setpoint.

The setpoint can be specified either externally or internally.

External: Setpoint specification via setpoint input terminal z20.Internal: Call--up of 1 to 4 adjustable setpoints via relays.

Depending on the version of the proportional amplifier, an external setpoint can be spe-cified in the form of a voltage or current signal.The current input has an internal resistance of 500 Ohm, such that for an external set-point of 0 to 20 mA, the internal voltage level (which can be measured at MS) is 0 to10V.

External setpoint specification for valves with two solenoids:If other sources are used for the setpoint specification instead of the voltages of +15Vsupplied by the proportional amplifier, these sources must be referred to the analogzero!

Internal setpoint specification:The internal setpoint specification is carried out by means of the setpoint trimmersA1/A2.The adjusted setpoints can be activated by means of the internal relays K1/K2.

2.2.1.2 Modulation LimitationThe trimming potentiometers AB A for solenoid A and AB B for solenoid B can be usedto attenuate the setpoint--specific modulation range of the power stage.It is thus possible to utilize only a sub--area of the valve characteristic (high resolution).

2.2.1.3 Zero--point Lift Function(only with proportional amplifiers for 2 solenoids)

The zero--point lift function enables the solenoid current for each solenoid to be liftedeven with extremely small setpoints; separate adjustment is provided via the trimmingpotentiometers Zero A and Zero B.The zero--point lift is always operative only for the particular solenoid which is subject tosetpoint control.

Service Manual


2.2.1.4 Zero--point Lift Suppression(only with proportional amplifiers for 2 solenoids)

The zero--point lift suppression is used to suppress the zero--point lift for setpoint specifi-cations in the range from approx. + 6% of the limit value (+10V / + 20 mA). This preventsthe solenoids from being activated alternately by very small setpoint fluctuations in thezero--range.


Amplifier Box



2.2.1.5 Utilization of a Sub--area of the Valve Characteristic(Example)

The zero--point lift and the modulation limitation make it possible to utilize sub--areas ofthe valve characteristic in the normal setpoint range.In the example below, the working range of the proportional valve with the characteristicQA = f(IA) or QA = f(w), see Figure a, is to equal only 20 -- 60% of the nominal rangewith a setpoint specification of 0 to +10V.

Adjustment:-- Set lift by means of trimmer Zero A in such a way that the lower range limit for QA

is reached at w = 0V (see Figure c).

-- Reduce the modulation limitation by means of trimmer AB A in such a way that theupper range limit for QA is reached with w = 10V (see Figure c).

The procedure is similar for the utilization of sub--areas of the other characteristic branch(solenoid B).

2.2.1.6 Ramp ShaperThe ramp shaper ensures a steady rise in the output voltage when the input voltagerises abruptly.After the elapse of the manipulating time, the input and output voltages are of identicalvalue. The ramp shaper fitted on the PCB enables two ramps to be separately adjustedand selected by means of relays.These relays can be activated either via an SPS control or via parallel activation with thesetpoint.The adjustment of ramp manipulating time is linear.

The jumpers enable internal or external operation to be selected separately for eachramp.

For internal operation, the trimmers on the proportional amplifier are used.

2.2.1.7 Superimposition of Hum (Iosc.)The trimming potentiometer Iosc. can be used to adjust the hum amplitude of the valvecurrent for solenoids A and B.The adjustment range is 0 to 40% of the modulation range. The hum frequency can beadjusted to 50Hz or 100Hz by means of a jumper.

The superimposition of hum (dither) on the solenoid current improves the static frictionand thus the hysteresis of the valve.

Optimum adjustment is achieved when small changes in the setpoint are registered bythe final control element, the hum amplitude used should always be the least possible.
