HARTRIDGE LIMITED Operating ManualHL030(EN), Issue 1, June 2005 1912. Channel B Current Used to apply an open loop current demand to the second channel of thepump control box (only required when using a Siemens pump as thesurrogate – see Section 4.3.1, otherwise set to 0 A).The function key actions are as follows:F1 Main Menu Returns to the Main MenuF2 Testplan Menu Opens the Testplan Menu. From here you can Save changes to thecurrent testplan, create a New testplan, load a different testplan, and editthe Testplan/Injector details. See Section 4.5.F3 Not used.F4 Start Test Start a test (with possibility to save results). See Section 4.3.5.F5 View Results Opens a dialog where you can select previously saved results to view.See Section 4.7.F6 T40 1:1 Metering mode temperature compensation (function key not enabled,this parameter is set in the testplan).F7 Print Print (only enabled in Results View – see Section 4.6)F8 Limits/Units Opens the standard Limits/Units screen.F9 Metering Mode Toggles the metering mode between Overcheck and Calibrate. Calibrateis the more accurate mode and should be used for taking results.F10 Metering Limits Opens the standard Metering Limits dialog.4.3 Test Setup and MethodThe basic parameters that will establish the condition of a CR injector are: Spray Pattern (checked on Testmaster) Delivery vs. pressure vs. pulse width Backleak flow (dynamic and static) Response TimeExample testplans are provided for each manufacturer. These contain the basic electricalcharacteristics for that manufacturer’s injector and typical demand settings for various conditions.They do not contain expected results values as these will be specific to each injector part number.These example testplans can be used as a basis for creating dedicated testplans for specificinjectors.The following instructions assume that the basic kit has been installed (see Section 2).4.3.1 Fit the Surrogate PumpMount the surrogate pump (either a Bosch CP1 with PCV or a Siemens Pump), and connect to thePump Control Unit (refer to HF1130 manual and associated bulletins).NOTE If using a Siemens pump connect the cable the opposite way around to normal i.e. fitthe connector labelled “FCV” to the pressure control valve, and fit the connector labelled“PCV” to the flow control valve. Additionally, set the “Channel B Current” to 2A (thisapplies 2A to the FCV so that it will deliver maximum flow).4.3.2 Load a TestplanWhen you first enter the CR Injector Test screen it will be mainly blank (as in Figure 4.1); you mustload a testplan to start testing.To load the example testplan for the relevant injector manufacturer, first press F2 to access theTestplan Menu (shown below), then select the Manufacturer and Part Number required, then click[Load Testplan], then [OK].THIS IS AN UNCONTROLLED DOCUMENT downloaded by Lukas Matuska on 16 Feb 2016Any technical intervention requires certified Hartridge training.
