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.
The term "manufacturer" refers to Parker Hannifin Corporation.

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.

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.

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.

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:

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.

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.
