SERVICES MANAGEMENT EXECUTIVE ENGINEERING SECTION EXECUTIVEEXPORT MANAGERPublication No. ACSZP0CAEdition: April 1998INTRODUCTIONThis equipment enables manually controlled electric power steering and automatic straight line wire guided steering. Manually controlled steering is available in either of the following options:-manually operated multi-turn steering using a tacho-generator fixed to the steering handle-manually operated return-to-center steering using a potentiometer attached to the spring returned steering handle that automatically centers steering when the handle is released.In addition, this hardware controls the guide wire acquisition when the truck is ap-proaching and seeking the guide wire for transition to automatic wire guided steering. Automatic straight line wire guided steering is possible for both directions of travel. Configuration options, manual steering adjustment and measurement functions, and troubleshooting operations are simplified with the use of the ZAPI hand held controller equipped with Eprom release number CKULTRA ZP3.01 or later.Improved safety and operation are provided by having one microprocessor perform operations and a second microprocessor execute perform supervisor functions.The microprocessors combined with the ZAPI hand held controller make service inter-face easy and direct, reducing adjustment and troubleshooting time. Increased steering motor performance and reduced noise levels are achieved by using MOSFET technol-ogy operating at 16 kHz, which is above the normally heard frequency band.EQUIPMENT FOR ADJUSTMENTZAPI Hand SetDigital multimeter that can measure AC voltages up to 10 kHz1 SYSTEM COMPONENTSThe automatic wire guidance system includes:1.1 TWO INDUCTIVE WIRE SENSORS (ANTENNAS)There is a REV (load wheel) antenna mounted under the cab and a FWD (DRIVE UNIT) antenna mounted at the drive end of the truck. Both sensors are mounted on the center line of the truck. Each antenna includes two pick up coils that detect guide wire signal strength. During normal wire guided operations one pick up coil in each of the antennas is to the left of the wire and the other pick up coils are to the right of the wire.1.2 5k W STEER ANGLE POSITION POTENTIOMETERA 10 turn 5 k W potentiometer is mounted directly to the end of the output shaft on the steering gear reduction box. This potentiometer measures the angle of the DRIVE UNIT (Master Drive Unit) directly. The full range of possible voltage output is approximately 0 - 5 VDC. This single potentiometer provides steer angle feedback information for manual steering and wire guidance. This potentiometer also provides information for steer angle indicator gauge mounted on the operator console of multi-turn steering equipped trucks.1.3 STEERING SERVO MOTOR CONTROL UNITa) A mother board marked ACSZPAOB operates the steering motor for both manualand automatic steering. There are two different mother boards available:1.A universal mother board that provides a maximum of 21 A at 24 - 80 VDC.2.A high output mother board that provides a maximum of 34 A at 24 - 48 VDC.b) A guidance (antenna processing) card marked ACSZPBOB converts the signalsfrom the antennas and from the steer angle feedback potentiometer into a bi-directional steering error that produces steering demand to the mother board.This steering error that produces steering demand is produced directly throughelectronic combination or comparison of the antenna feedback and the steer angle feedback. This does not go through a microprocessor.1.4 OPERATOR CONSOLEIn addition to the steer handle feedback device the following devices are also mounted in the operator console:a)Key switchb)Manual/automatic steering selection switch (AUTO SEL)c)An audible warning buzzer (BUZZER)d)An "automatic" indicator lamp (AUTO LED)e) A "manual" indicator lamp (MAN LED)1.5 STEERING SERVO MOTORThe steering system includes a permanent magnet DC servo motor with a rated power that is:a)20 A current rating (Imax = 34 A) if the battery voltage is 48 V DC or lessb)12 A current rating (Imax = 21 A) if the battery voltage is greater than 48 V DC.1.6 STEERING HANDLETwo operator steering input options are provided. These may be selected using the ZAPI hand held controller. They include:a) A multi-turn steering handle or wheel attached to a tacho-generator. The recom-mended tacho-generator is (Airpax Part No. 24 VDC - 9904-120-16206). Mount-ing the tacho-generator to eliminate axial or radial loading on the input shaft isimportant to reliable operation.b) A 180 degree rotation steering handle attached to a potentiometer. The potentio-meter provides the steering system with the angle of the steering handle.1.7 LINE DRIVER (GUIDE WIRE SIGNAL GENERATOR)The line driver provides a sinusoidal (alternating current) signal of the required fre-quency and strength to the guide wire.2 ELECTRICAL SPECIFICATIONS2.1 BATTERY VOLTAGE RANGEVoltage input range for different releases of steering mother boards.Universal release24 - 80 VDC24/48 release24 - 48 VDC2.2 STEER MOTOR CURRENT RANGEUniversal release Imax £ 21 A DC. Adjustable with TM3.24/48 release Imax £ 34 A DC. Adjustable with TM3.2.3 GUIDE WIRE SIGNAL6.25 kHz @ 78 mA RMS (± 50 Hz and 60 - 90 mA)Other frequencies are possible especially including:5.2 kHz @ 35 mA RMSOther frequencies are possible such as 7 and 10 kHz.As the guidance frequency changes, a non-standard guidance card (ref. ACSZPBOB) has to be installed which has the narrow band pass filters tuned to the different fre-quency. Usually, due to changing signal strength associated with changing frequen-cies, new guidance antennas will also be required. The antennas have the gain modi-fied to ensure adequate signal strength arrives at the control card.Note: If the signal strength and frequency change in agreement with the following formula, then no new antennas are required with a changing frequency.I fd = I f0 + (((f0 - f d)/f0) x I f0)I f0 = Current at 6.25 kHz (78 mA RMS)I fd = Current at desired frequencyf0 = 6.25 kHzf d = Desired frequency2.4 COMMAND DEVICE SPECIFICATIONS2.4.1 TACHO GENERATORTach Generator is to be AIRPAX 24 VDC - Part No. 9904-120-16206. Use of other devices may provide non-optimum performance.2.4.2 POTENTIOMETERSPosition potentiometer control loops require typical pot values of 10 k W for both return-to-center steering and steering angle feedback. 10 k W³ steering handle feedback pot value ³ 2.5 k W. Satisfactory performance requires that both of the following conditions be met:1)Provide 80% of the electrical range of the steering angle feedback potentiometercorresponding to 180 degrees of DRIVE UNIT steering angle.2)Provide at least 40% of the electrical range for the steering handle potentiometer.3 MECHANICAL SPECIFICATIONSFig. 3.13.1 STEERING REDUCTION RATIOAt rated servo-motor RPM with a reduction gear, the steering speed should be equal to about 180 degrees in 5 seconds. There should also be adequate torque generated to statically steer the truck on smooth concrete.3.2 STEERING ANGLE FEEDBACK POTENTIOMETER REDUCTION RATIO The steering angle feedback potentiometer should rotate approximately for the 80% of its total numbers of turns corresponding to 180 degrees of steering angle. The higher is the percent excursion, the better are resolution and accuracy.The pot. shaft is directly connected to the output shaft of the steer gear box and is secured with a set screw.3.3 INSTALLING ANTENNAFig. 3.3.1The center of the antenna should be aligned with the center line of the truck. The DRIVE UNIT antenna (FWD ANTENNA) is mounted behind the DRIVE UNIT. The loadFig. 3.3.2The forward and reverse antennas must be mounted so the coil side of the antennas both face the same direction.Fig. 3.3.3Fig. 3.3.4Fig. 3.3.54 SYSTEM DESCRIPTION4.1 AUTOMATIC WIRE GUIDED STEERINGThe guide wire embedded in the floor induces an electrical signal in the antennas mounted on the center line of the truck proportional to the position of the truck in rela-tion to the wire. The control electronics continuously steers the truck in an effort to keep the combination of steering angle error and antenna error = zero. When all an-tenna coils have an equal strength signal there is no steering demand.4.2 MANUAL STEERING WITH TACHO GENERATORThis option uses a tacho generator attached to the steering wheel to convert the steer-ing wheel rotation into an electrical signal. The control logic sets the steer servo-motor in motion at a speed that increases with the speed of the steering wheel. Steering sensitivity and maximum speed are adjustable by using the ZAPI hand held controller.4.3 MANUAL STEERING WITH POTENTIOMETERThis option uses a potentiometer attached to the steering handle to convert handle motion into an electrical signal. The response speed and precision are adjustable using the ZAPI hand held controller.4.4 WIRE GUIDED STEERING OPERATING SEQUENCEFor your reference here are the different operating modes and light and buzzer opera-tions.

The steering changes to Wire Acquisition Mode. The operator continues to manually steer the truck. The steering/guidance controller automatically reduces truck travel speed to slow by opening a speed reduction relay.If the truck is approaching the wire load first, then both antennas have to detect the guide wire before manual steering is taken from the operator and automatic steering attempts to capture the wire. This requires an angle of approach of not more than approximately ± 5 degrees to the guide wire. The operator continues to be responsible for steering until the wire is fully captured.If the truck is approaching the wire DRIVE UNIT first, then only the DRIVE UNIT an-tenna has to detect the guide wire before manual steering is taken from the operator and automatic steering attempts to capture the wire. This requires an angle of approach of not more than approximately ± 30 degrees to the guide wire. The operator continuesFig. 4.4.2Automatic Wire Guided Steering Mode - When both antennas are aligned with the guide wire, then fully automatic steering is enabled. The truck may travel at full speed. The truck is fully in control of steering and automatic stopping is enabled. The signal in the antennas is used to steer the truck.If the truck is not aligned with the guide wire in Automatic Mode, then the truck auto-matically stops, brakes are applied, both the AUTO and MANUAL lights are frozen, and the buzzer has the error audibly encoded. Counting the number and sequence of beeps provides an error code to the operator.4.5 REAL TIME RUNNING CICLE FLOWCHARTFig. 4.5.15 SYSTEM CONFIGURATION5.1 JUMPER CONFIGURING5.1.1 WIRE GUIDED CARD (ACSZPB0B) JUMPER.J1 = Specifies the control logic for forward and reverse direction of travel on traction. It should be configured in one of the following ways:a)J1 as in the figure 5.1.1 means the enabling contacts for TRAVEL are ACTIVEb)NOTE: It is important to set the "DIR INP ACTIVE LOW" (see par. 12.6.2) option using the ZAPI hand set:OFF if a) was chosen for J1ON if b) was chosen for J1.5.1.2 MOTHERBOARD (ACSZPA0B) JUMPERS.J1 = Factory configured with the jumper installed. This is a microprocessor functional mode selection.J2 = Select the supply voltage for the command encoder.J3, J4, J5 = For special applications only (see par. 8.2).J6 = When connected gives the speed reduction switch a ground (GND) reference. The reference is normally floating.J7 = When connected gives the locking in straight direction steering switch a ground (GND) reference. The reference is normally floating. This features is to control an electromechanical steer straight feature in automatic mode.J8 = When connected gives the steering alarm switch a ground (GND) reference. The reference is normally floating. This provides a single point disconnect for EPS and5.2 POWER CONNECTION DIAGRAMThe functional diagrams concerning the possible configurations are shown.Four different operating options (Tacho-generator + wire guidance, Tacho-generator steering only, Pot steering + wire guidance, and Pot steering only) are provided. "Tacho-generator steering only" and "Pot steering only" support "Automatic Centering" also.5.3.1 INTERFACE DESCRIPTION:a)The steering angle feedback potentiometer should be rigidly mounted to the steer-ing linkage with no joint clearance..b)The FWD antenna is mounted on the DRIVE UNIT end of the truck.c)The REV antenna is mounted on the load end of the truck.d)The FWD travel input corresponds to travel in the drive unit direction.

This pin is common with Pin 1 of the guidance board (eight pole)connector. Pins 2 on connector D on the mother board is connected to REV (load wheel) travel input. This pin is common with Pin 2 of the guidance board (eightpole) connector.Each direction input may be active high (plus battery) or low (minus battery).Specify the mode of operation by configuring the Jumper J1 on the guidance(upper) card (see 5.1.1) and select the operation level using the ZAPI hand held controller (see 12.6.2).f)Pin 9 of connector D on the motherboard is connected to the highest voltagepotential side of the traction motor armature. This pin is common with pin 4 of the guidance card (eight pole) connector. Pin 11 of connector D on the motherboard should be connected to the lowest voltage potential side of the traction motorarmature. This pin is common with pin 8 of the guidance card (eight pole) connec-tor (see 6.1.4).g)The AUTO LAMP comes on when there is a request for wire guided steering, i.e.,when the guidance switch is turned on. It is blinking during speed reduction condi-tions. The active AUTOSEL level for automatic guidance (low or high) isselectable using the ZAPI hand held controller (see 12.6.1).h)The MAN LAMP is on during manual operation and goes out as soon as the trucksteers independently from the manual input. The MAN LAMP is blinking during slow down conditions.i) Pin 3 of connector D on the mother board is internally connected to a normallyopen (NO) contact on the mother board. This contact is closed when the keyswitch is turned on. The contact opens when there is an alarm. This contactprovides ground (GND) reference to the brake relay and the main steering relay.When the brake relay loses this ground and opens, the brakes are applied andtraction enable ground to the traction card is lost. (Note:The jumper J8 should be installed on the motherboard.)j)Pin 5 of connector D on the mother board is internally connected to a normally open (NO) contact. This contact is closed when the key switch is turned on and remains in such a position while in manual mode and in wire-seeking operations.The contact opens when the truck is perfectly aligned to the wire (AUTOMATIC mode). This contact should provide and remove ground (GND) connection to an electromechanical device locking the wheel in a quasistraight position. (Note:The jumper J7 should be installed on the motherboard).k)Pin 6 and 15 of connector E on the mother board are internally connected to a normally open contact on the mother board. This contact is closed by the keyswitch and open in case of one of the following speed reduction conditions:1)If the truck is in the manual steering mode and is close to a guide wire. (Mini-mizes possibility that an operator will go fast when inside an aisle and not onwire guidance.)2)When the truck is in the wire acquisition mode until both antennas are alignedwith the guide wire.3)When the truck is in the wire guided mode and has shifted sideways more than2/3 of the "lateral out" alarm threshold (see 9.9).l)Pin 14 of connector E on the motherboard provides 0 - 4 VDC to control the steering angle indicator gauge LEDs. Pin 4 and Pin 5 of connector E on themotherboard respectively provide negative and postive 12 VDC to the steering indicator.5.4 TACHO-GENERATOR STEERING WHEEL AND AUTOMATIC CENTERING Refer to the previous section on Tacho-Generator Steering with wire guidance.
