number<\/li>\n<li>Controller<\/li>\n<li>Hydraulic configuration<\/li>\n<\/ul>\n<hr \/>\n<h1>Why Are 220, 150 and 40 L\/min Used?<\/h1>\n<div>These values create specific test conditions during calibration.<\/div>\n<div>Do not interpret them as universal attachment operating specifications.<\/div>\n<div>The calibration sequence uses:<\/div>\n<ul>\n<li>220 L\/min for high-flow pressure calibration<\/li>\n<li>150 L\/min for high-flow flow calibration<\/li>\n<li>40 L\/min for low-flow pressure calibration<\/li>\n<\/ul>\n<div>After testing, restore the attachment settings to values suitable for the actual tool being used.<\/div>\n<hr \/>\n<h2>Calibration Value vs Attachment Setting<\/h2>\n<div>The ATS calibration value and the normal attachment setting serve different purposes.<\/div>\n<div>Calibration values correct the relationship between machine control commands and hydraulic output.<\/div>\n<div>Attachment settings define how much flow and pressure a specific attachment should receive during normal operation.<\/div>\n<div>For example, do not operate an attachment rated for substantially less hydraulic flow at the maximum calibration test value.<\/div>\n<div>Always follow the attachment manufacturer\u2019s hydraulic specifications.<\/div>\n<hr \/>\n<h2>Restore the Original Attachment Configuration<\/h2>\n<div>After calibration, restore the machine\u2019s normal attachment profile.<\/div>\n<div>Check:<\/div>\n<ul>\n<li>Attachment type<\/li>\n<li>One-way or two-way operation<\/li>\n<li>Hydraulic flow<\/li>\n<li>Pressure<\/li>\n<li>Control mode<\/li>\n<li>Joystick settings<\/li>\n<li>Pedal settings<\/li>\n<\/ul>\n<div>Do not leave the temporary calibration profile active unless it matches the real attachment specification.<\/div>\n<hr \/>\n<h2>Post-Calibration Verification<\/h2>\n<h3>Restart the Machine<\/h3>\n<div>After writing configuration changes:<\/div>\n<ol>\n<li>Shut the machine down normally.<\/li>\n<li>Restart it.<\/li>\n<li>Confirm the settings remain stored.<\/li>\n<li>Recheck the ATS configuration.<\/li>\n<\/ol>\n<div>If configuration data disappears after every key cycle, investigate controller communication or the configuration-writing process rather than repeatedly recalibrating the machine.<\/div>\n<hr \/>\n<h3>Scan for Fault Codes Again<\/h3>\n<div>After calibration, check for new or remaining active faults.<\/div>\n<div>Pay particular attention to:<\/div>\n<ul>\n<li>Pump control<\/li>\n<li>Hydraulic solenoids<\/li>\n<li>Pressure sensors<\/li>\n<li>Joystick inputs<\/li>\n<li>Pedal inputs<\/li>\n<li>CAN communication<\/li>\n<\/ul>\n<hr \/>\n<h3>Test the Actual Attachment<\/h3>\n<div>Restore the correct attachment profile and test the machine under controlled conditions.<\/div>\n<div>Check:<\/div>\n<ul>\n<li>Attachment speed<\/li>\n<li>Correct direction<\/li>\n<li>Smooth operation<\/li>\n<li>Engine response<\/li>\n<li>Hydraulic noise<\/li>\n<li>Hose movement<\/li>\n<li>Oil temperature<\/li>\n<li>Leakage<\/li>\n<\/ul>\n<div>Begin with conservative pressure and flow settings based on the attachment manufacturer\u2019s specifications.<\/div>\n<hr \/>\n<h2>ATS Diagnostic Logic<\/h2>\n<div>Comparing pressure and flow together can quickly indicate where the fault is

Diagnosing Fault Codes<\/h3>\n<div>Repair active sensor, solenoid, pump-control, or communication faults first.<\/div>\n<hr \/>\n<h3>Testing With Cold Hydraulic Oil<\/h3>\n<div>Cold oil can change hydraulic resistance and measured flow.<\/div>\n<div>Warm the machine according to the applicable service procedure.<\/div>\n<hr \/>\n<h3>Using the Wrong Pressure Test Point<\/h3>\n<div>Pump pressure and attachment-coupler pressure may not be identical.<\/div>\n<div>Always use the specified test point.<\/div>\n<hr \/>\n<h3>Selecting the Wrong Hydraulic Circuit<\/h3>\n<div>An incorrect 1-way, 2-way, or switchable configuration can produce misleading test results.<\/div>\n<hr \/>\n<h3>Increasing Calibration to Compensate for a Mechanical Fault<\/h3>\n<div>If you can&#8217;t achieve the required pressure or flow within a reasonable calibration range, stop adjusting.<\/div>\n<div>Investigate the hydraulic system.<\/div>\n<hr \/>\n<h3>Forgetting to Restore the Attachment Profile<\/h3>\n<div>The test values used during calibration may be unsuitable for normal attachment operation.<\/div>\n<div>Restore the original profile after testing.<\/div>\n<hr \/>\n<h2>When ATS Calibration Will Not Fix the Problem<\/h2>\n<div>Consider this example:<\/div>\n<div>Symptom: Attachment operates slowly.<br \/>\nPressure: Correct.<br \/>\nFlow: Low.<\/div>\n<div>The likely next diagnostic direction is:<\/div>\n<ul>\n<li>Pump delivery<\/li>\n<li>Pump control<\/li>\n<li>Flow-control valve<\/li>\n<li>Hydraulic restriction<\/li>\n<\/ul>\n<div>Increasing relief pressure is not the correct repair.<\/div>\n<div>Another example:<\/div>\n<div>Pressure at the valve block: Correct<br \/>\nFlow at the valve block: Correct<br \/>\nAttachment: Still slow<\/div>\n<div>Check downstream components:<\/div>\n<div>main valve \u2192 hose \u2192 quick coupler \u2192 attachment \u2192 return\/case drain<\/div>\n<div>This is where hydraulic testing becomes more important than software calibration.<\/div>\n<hr \/>\n<h2>Using JCB ServiceMaster During ATS Diagnosis<\/h2>\n<div>JCB ServiceMaster helps you check whether the machine configuration matches the installed hydraulic

On compatible JCB excavators, it manages auxiliary hydraulic settings for different attachments.<\/div>\n<hr \/>\n<h3>Can JCB ServiceMaster calibrate ATS on its own?<\/h3>\n<div>No. ServiceMaster can verify or change relevant machine configuration, but the hydraulic calibration procedure also requires actual pressure and flow measurements.<\/div>\n<hr \/>\n<h3>Is 220 L\/min the correct setting for my JCB attachment?<\/h3>\n<div>Not necessarily.<\/div>\n<div>In this procedure, 220 L\/min is a temporary high-flow pressure-calibration setting. Configure the attachment to its hydraulic requirements and the excavator\u2019s approved operating range.<\/div>\n<hr \/>\n<h3>Why does the attachment remain slow even though hydraulic pressure is correct?<\/h3>\n<div>Normal pressure does not guarantee normal hydraulic flow.<\/div>\n<div>Measure flow and investigate:<\/div>\n<ul>\n<li>Pump output<\/li>\n<li>Flow-control valve<\/li>\n<li>Hydraulic hoses<\/li>\n<li>Quick couplers<\/li>\n<li>Attachment restriction<\/li>\n<\/ul>\n<hr \/>\n<h3>Does every JCB 200 Series excavator use the same ATS calibration?<\/h3>\n<div>No.<\/div>\n<div>ATS configuration and calibration requirements can vary by model, serial number, hydraulic option, controller, and installed equipment.<\/div>\n<div>Use the service information for the exact machine.<\/div>\n<hr \/>\n<h3>Should ATS be recalibrated every time an attachment is changed?<\/h3>\n<div>Normally, no.<\/div>\n<div>Once the machine\u2019s hydraulic control system is correctly calibrated, different attachments are generally managed through their individual ATS profiles.<\/div>\n<div>Recalibration corrects the machine\u2019s hydraulic control relationship, not the normal attachment setup.<\/div>\n<hr \/>\n<h2>Final ATS Calibration Checklist<\/h2>\n<div>Before returning the excavator to service, confirm:<\/div>\n<ul>\n<li>Machine model and serial number were verified.<\/li>\n<li>ATS configuration matches installed hardware<\/li>\n<li>High-flow pressure was checked.<\/li>\n<li>High-flow flow was checked.<\/li>\n<li>Low-flow pressure was checked.<\/li>\n<li>Hydraulic test equipment was removed safely.<\/li>\n<li>Temporary calibration settings were removed.<\/li>\n<li>Correct attachment profile was restored.<\/li>\n<li>Attachment pressure and flow remain within specification.<\/li>\n<li>No active hydraulic-control faults remain.<\/li>\n<li>Settings remain stored after restart.<\/li>\n<li>Actual attachment operation was verified.<\/li>\n<\/ul>\n<div>When ATS values are correct but hydraulic performance is still abnormal, continue diagnosing the physical hydraulic circuit rather than repeatedly changing calibration values.<\/div>\n<div><\/div>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>JCB Advanced Tool Select (ATS) is used on compatible excavators to control auxiliary hydraulic flow and pressure for different attachments.<!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":1,"featured_media":25120,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2959],"tags":[4555,4552,4553,4554,3056],"class_list":["post-25119","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-jcb-machine-trouble-repair","tag-advanced-tool-select","tag-jcb-200-series","tag-jcb-ats-calibration","tag-jcb-excavator-hydraulics","tag-jcb-servicemaster-4"],"views":53,"_links":{"self":[{"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/posts\/25119","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/comments?post=25119"}],"version-history":[{"count":1,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/posts\/25119\/revisions"}],"predecessor-version":[{"id":25129,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/posts\/25119\/revisions\/25129"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/media\/25120"}],"wp:attachment":[{"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/media?parent=25119"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/categories?post=25119"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/tags?post=25119"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
