Foreword

Hartridge Ltd. reserves the copyright of all information and illustrations in this publication which is

was originally supplied. The publication may not be reproduced in part or in whole without the consent

in writing of this company.

Safety Information

Warnings, Cautions and Notes

The precautionary notes in this publication, indicated by the words WARNING, CAUTION, or NOTE

provide information about potential hazards to personnel or equipment. Ignoring these notes may

lead to serious injury to personnel and/or damage to equipment. These notes appear as follows:

WARNING! INDICATES THAT A SITUATION MAY BE HAZARDOUS TO PERSONNEL.

INSTRUCTIONS ARE PROVIDED FOR AVOIDING PERSONAL INJURY.

CAUTION! Indicates that conditions exist that could result in damage to equipment.

Instructions are provided to prevent equipment damage.

NOTE Indicates additional information for clarification where there may be confusion.

Operational Warnings

WARNING! HIGH PRESSURE FLUID SPRAYS CAN CAUSE SERIOUS INJURY

OR DEATH.

COMMON RAIL SYSTEMS OPERATE AT EXTREMELY HIGH PRESSURES. IF

USED AS INSTRUCTED THE TEST KIT WILL RELIEVE ANY HIGH PRESSURE

WHENEVER THE GUARD DOORS ARE OPENED.

DO NOT ATTEMPT TO BYPASS THE PRESSURE DUMP VALVE OR THE

SAFETY INTERLOCK.

Safety glasses must be worn when working on this equipment for the following

reasons:

1. The test equipment is capable of producing high pressure fluid jets or sprays

which can cause severe eye injury in the event of a malfunction.

2. The test stand uses calibration fluid which is harmful to the eyes.

Always start the system running at a low pressure and visually check for any leaks

before setting higher pressures. This particularly applies having just mounted a

system, or having just replaced a component.

Do not open the guard while the system is running. Wait for the test bench drive to

stop and for the pressure to decay to a lower level before opening the guard.

Operating Manual HARTRIDGE LIMITED

4 HL030(EN), Issue 1, June 2005

Impervious gloves and overalls should be worn if regular contact with ISO4113 test

fluid is likely. The pump, high pressure control valve, and delivery lines to the

metering unit will become very hot after running. Wear protective gloves if

handling immediately after use. Refer to the Health & Safety Data Sheets.

General Warnings

Make sure there is adequate ventilation. Oil vapour may be released from hot

fixtures or high pressure leaks. The specific directions in Health & Safety Data

Sheets must be adhered to.

Keep hands and the body away from fluid sprays, especially injectors, leaking high

pressure pipes and seals. High pressure injection through the skin can result in

fatal injury. In the event of injection into the skin, seek urgent medical attention.

Refer to the Health & Safety Data Sheets.

Burns will occur to the hands if certain parts of the test stand or equipment under

test are touched. Keep hands away from the calibration fluid heater element and

injector or high pressure pipes after periods of extended running.

Safety footwear must be worn in the test area at all times. Injury to the feet may be

sustained in the event that equipment under test (during loading or unloading) or

test stand covers are dropped.

Severe injury can be caused by slipping on spilt oils or fluids. All spillages of fluids

in the test area must be dealt with immediately. These can be mopped up and

mineral absorbent material spread over the affected area.

Use calibration fluid and lube oil of the correct specification only. Obtain the

manufacturers Health & Safety Data Sheets and follow the advice given therein.

Prolonged and repeated contact with oil products, ingestion or excessive and

prolonged inhalation of oil mists can be detrimental to health. Use an appropriate

barrier cream.

Ensure that the servicing requirements and intervals as set out in the Maintenance

section are adhered to. Operate and service this equipment only if competent to do

so. Carry out regular inspections to make sure all high pressure connections are

tight and safe.

HARTRIDGE LIMITED Operating Manual

HL030(EN), Issue 1, June 2005 5

Remove any tools, cleaning rags or other debris from the test stand before starting

up. Make sure the inching bar is not fitted to the test stand before starting up.

There must be no naked flames. Potentially flammable vapours are present in the

test stand and ignition is possible although unlikely. Smoking whilst operating the

equipment is strictly forbidden.

Accidents can occur to unauthorised personnel during testing. Untrained person(s)

must not be present in the test area when the equipment is operating. Only

qualified personnel are to operate this equipment.

Ensure good levels of lighting for safe, efficient equipment operation.

1. Introduction

The HK900 Common Rail Injector Test Kit is designed to be fitted to the AVM2-PC Test Stand to

enable testing of Common Rail injectors. Additional mounting parts are available for testing specific

injector types.

NOTE: The AVM2-PC must be fitted with the following items in order to use the HK900 (all

available separately):

- HB378 Common Rail Base Kit

- HF1130 Common Rail Pump Test Kit

- Version 33 (or later) Magmah PC software

1.1 Specification

Refer to packing list for kit contents. The AE32 Injector Control Unit specification is as follows:

Power Supply

120/240V AC 50/60Hz Single Phase

Control Features

4-channel injector drive circuit, suitable for current Bosch, Delphi and Denso

solenoid injectors, and Siemens piezo injectors.

Measurements

Single channel solenoid resistance measurement.

4-channel response time measurement (via response time unit).

Auxiliary voltage measurement channel.

Miscellaneous

Status reporting.

Interface to HK901 for 4-line backleak flow and temperature measurement.

1.2 Related Documents

This manual describes the general operation of the HK900 kit for testing Common Rail injectors.

Bulletin TIB195/11 (also provided in this kit) outlines the accessories available and which injector

applications they cover.
