Warnings

1 Introduction

1 Introduction

These instructions are to be used as a reference tool for the vehicle manufacturer’s design, production, and service personnel.

The user of these instructions should have basic knowledge in the handling of electronic equipment.

Warnings

Sections marked with a symbol in the left margin, must be read and understood by everyone using the system, carrying out service work, or making changes to hardware and software.

The different symbols used in this manual are defined below.

W

ARNING

Sections labeled WARNING with a caution symbol in the left margin, indicate that a hazardous situation exists. We use warnings, marked with the warning symbol, in two ways.

• As a strong recommendation about work practices when using the product in the machine (e.g. routines when updating an application). This use is common to the term 'hazardous situation', that a person is exposed to a hazard.

• As a way of pointing out important information for the machine designer that in some way relates to safety. This includes the design of the physical machine, and also the application program being developed for the control system.

Not all document sections that contain information about safety are marked with a warning symbol (there would be warnings everywhere). Failure to comply with the recommendations can cause unintentional, and unexpected behavior of the control system. This can potentially cause death, serious injury or property damage.

N

OTICE

Sections labeled NOTICE with a notice symbol in the left margin, indicate there is important information about the product. Ignoring this could result in less than optimal performance, or damage to the product.

Contact the manufacturer if there is anything you are not sure about or if you have any questions regarding the product and its handling or maintenance.

3 Product description

IQAN-TOC8

The IQAN-TOC8 is a stand alone controller designed for controlling hydraulic systems in vehicles and machinery, using 12/24 Vdc power supply.

The IQAN-TOC8 controller.

Input

The IQAN-TOC8 has ten (10) inputs. These can be used as voltage inputs for connection of 0-5 Vdc signals or as digital inputs. VIN A thru VIN D can be configured as frequency inputs for measuring frequency. Voltage inputs and frequency

inputs, share positions, see below.

(10) Voltage inputs VINA, VINB,VINC, ......,VINJ or

(10) Digital inputs DINA, DINB, DINC, ......, DINJ or

(4) Frequency inputs FINA, FINB, FINC, FIND & (6) Voltage inputs VINE -VINJ

Output

The IQAN-TOC8 has 2 double current outputs for controlling proportional valves or devices. The unit has 6 digital outputs for on/off valves, or 3 double PWM outputs

(Pulse Width Modulation) for controlling standard proportional and Pulsar

TM

type valves. Digital and PWM outputs share positions, see below.

2 double Current outputs

6 Digital outputs, or 3 double PWM outputs

In order to increase the performance of the current outputs when controlling proportional valves, both the dither frequency and the dither amplitude can be adjusted.

The digital output channels also have PWM, soft start and peak & hold features available.

CAN related functions

IQANsimulate software uses the CAN-bus (CAN = Control Area Network) to communicate with the controller when proving applications off of the machine

(requires NI CAN card). The CAN-bus may be used by the TOC8 for SAE J1939 communication with engine electronics and for system control.

Instruction book, IQAN- TOC8 5

Internal diagnostics

4 Safety

4 Safety

Internal diagnostics

The module performs a number of self-checks that improve safety. Checks include monitoring of voltage supplies, checksums on memory and a watchdog that monitors software execution. The module is using a real time operating system which supervises software execution.

If a critical error is detected, the module is stopped, with CAN-bus and outputs off.

CAN-bus interruption

The IQAN-TOC8 module monitors the CAN-bus (when used for SAE J1939) for interruptions in communication.

An error will be presented with a related blink code on the IQAN-TOC8 status LEDs.

Current check

For the proportional outputs when used in current mode, a current check is performed.

If an error is detected, this will be indicated on the module, and the output will shut off.

The module can detect open-circuit, short-circuit to +BAT/-BAT or short-circuit to other proportional output and return pins.

Emergency stop

W

ARNING

Risk of injury!

The emergency stop must disconnect the power supply to the module; do not connect the emergency stop as a signal input only.

The emergency stop must be installed so that the risk of reverse feed of the module is

avoided, see section Emergency stop, on page 9.

Communication

6 Installation

Communication

RS232 and modem connection

The IQAN-TOC8 has an RS232 interface for communicating with the programming software, IQANdevelop. A flying lead, panel-mount, adapter cable, 5030089, may be connected to the TOC8 to provide an HR12 connector interface. This will match to the

PC communication cable provided in the IQANdevelop software package.

Instead of using recommended Parker adapter cable 5030089, a DB9-F serial connector may be wired to connect directly to a PC. The basic wiring for use of a DB9-F serial connector is shown below.

When using the recommended Parker adapter cable, 5030089, the connection from

TOC8 to PC can be made with the IQANdevelop included cable, 5030024, and from

TOC8 to modem with a separately purchased cable, 5030080.

N

OTICE

The ’Remote Diagnostic’ cable 5030080 must be used when connecting a modem to the TOC8.

Use of the MDM-RS232 cable 5030024 may damage the modem.

Using a modem

Start modem communication as follows:

• Attach the modem to the TOC8.

• Power up the modem first, then power up or reset the TOC8.

• Wait 45 seconds for the modem to initialize. The TOC8 will blink a double fast yellow code to indicate the modem is attached.

• Dial up the modem -- the TOC8 will automatically answer. A fast yellow-red double blink indicates ringing.

• If a ’Reset Master’ command is sent or a new application is downloaded, the TOC8 will reset. Modem communication will not cease but with some equipment the blink code will change from the fast double yellow blink code to the normal status single blink.

CAN connection

The module has a CAN interface that can be used to connect to SAE J1939 or similar bus for communication between IQAN-TOC8 and other systems.

Current outputs

6 Installation

Current outputs

The current output signals control proportional valves and devices. For the current

range see Appendix A, on page 22.

Dither frequency and amplitude

To obtain the best performance from proportional valves the control produces a direct current (DC) with a dither. The dither frequency and the dither amplitudes can be adjusted in IQANdevelop software. Depending on what kind of valve is to be used, a certain recommended dither frequency/amplitude set-up can be supplied by Parker

Hannifin Corporation in order to obtain an optimized valve hysteresis. Both frequency and amplitudes will then be set using IQANdevelop software.

Connecting loads to current outputs

Connecting a load, e.g. one proportional valve, to the current output is done by using the COUT/CRET pair positions.

EXAMPLE

Positive direction:

Connect the proportional valve to the COUT-A, position 17 and the CRET-A+, position 18 respectively.

Negative direction:

Connect the proportional valve to the COUT-A, position 31 and the CRET-A- , position 32 respectively.

Peak and Hold

The Peak and Hold feature makes it possible to decrease the voltage to the valve solenoid. Shortly after a valve has been activated, the voltage can be decreased to a lower level, sufficient to maintain the position of the valve, but also reducing the heat generated in the valve (due to this lower voltage).

The reducing of heat, is the primary reason for selecting the Peak and Hold feature.

Both the peak time and the hold value are set up in IQANdevelop software.

Digital outputs

6 Installation

Connecting loads to digital outputs

Connecting of loads to the digital outputs such as on/off valves is done by using the

DOUT positions and chassis as ground.

Protection against voltage transients

A clamping diode must be placed between the digital output and ground, as close to the load as possible, to protect the output against high voltage transients.

For example: use diode: 1N5408 (3A/1000V).

Depending on load, other clamping diodes might be used instead.

EXAMPLE

Connect the on/off valve to the digital output using the DOUT-A, position 21, and the chassis as ground.

A clamping diode must be placed as close to the load as possible, see figure below.

PWM outputs

6 Installation

PWM outputs

The PWM outputs (Pulse Width Modulation) control pilot valves. Maximum load should not exceed 3.0 A per output.

Connecting loads to PWM outputs

The load is connected between the PWMOUT and the chassis ground.

Maximum load per output, see Appendix A, on page 22.

Protection against voltage transients

A clamping diode must be placed between the output and ground, as close to the load as possible, to protect the output against high voltage transients.

For example: use diode: 1N5408 (3A/1000V).

Depending on load, other clamping diodes might be used instead

EXAMPLE

Positive direction:

Connect the load between the PWMOUT-A, position 22, and the chassis as ground.

Negative direction:

Connect the load between the PWMOUT-B, position 21, and the chassis as ground.

A clamping diode will be placed as close to the pilot valve as possible.

ARNING

Risk of injury!

If the control system is not fitted properly, the machine could move uncontrollably. The machine’s engine shall not be started before the control system is completely fitted and its signals are verified.

Starting the control system

Start the control system as follows:

• Prior to start, all modules and cables are to be fitted correctly.

• Check fuses, i.e. make sure that the supply voltage to the modules is equipped with the correct fuse.

• Make sure that connections for supply voltage and return lines are correct in the cable’s conductor joint.

• Make sure an emergency stop is installed.

The emergency stop should disconnect the supply voltage to all modules. Alternatively, the emergency stop may also shut off the diesel engine or a dump valve, and with that, depressurize the hydraulic system.

Prepare for system start

W

ARNING

Make sure no one is in dangerous proximity to the vehicle to avoid injuries when it starts.

Prepare for the initial system start as follows:

• The engine for the hydraulic system’s pump shall be in off position.

• Make sure that all connectors are properly connected.

• Turn on the control system.

• Make sure that voltage is being supplied to all modules; the power/status diode shall be illuminated on all modules. Also, make sure that the master is in contact with all modules by reading the master’s display.

• Make sure the emergency stop is functioning properly.

Start the system

Start the system as follows:

• Start the engine for the hydraulic system’s pump, assuming that the above mentioned inspections have been carried out and shown correct values.

Calibrate and adjust input and output signals according to the instructions related to the master menu system and check each and every output function carefully.
