EZ101C AUTOMATIC EZOBILITY GAUGE Safety 9 Safety Gauge Safety Checklist Gauge safety features should be tested regularly to ensure correct and safe operation. We recommend quarterly inspection of EZ101C AUTOMATIC EZOBILITY GAUGE safety features using the following checklist. If any safety feature does not operate, stop using the gauge immediately and rectify the problem. Contact Versatile Technology for advice and replacement parts. Features Tasks Cabinet Ensure all panels are fastened shut. Power Supply Module Supply Module Cover is in place and Mains wiring is inaccessible. Warning labels are fitted. Electrical Safety Test Perform Electrical Safety test and record results. (Refer to the 'Electrical Safety' section of the manual.) 'Tested for Electrical Safety' adhesive label is affixed. Door Interlocks Check that the interlock switch is working. Test mode should not commence if the interlocked door is open. If door is opened gauge should stop. Comments VERSATILE TECHNOLOGY EZ101C AUTOMATIC EZOBILITY GAUGE Safety Features Tasks Mains Enclosures Ensure mains wiring is covered and inaccessible Emergency Stop Test the operation of the emergency stop regularly. In normal test mode, press Emergency Stop button, the test should stop immediately. Labels All labels are affixed and legible. Pneumatic Setting Ensure that air pressure is set within guidelines and does not exceed recommended maximum.

In conjunction with AS3760:2001, this document specifies in-service safety inspection and testing protocols and criteria for the testing of Versatile Technology Gauging equipment. Action Such equipment, without being dismantled, needs to be subjected to routine inspection and testing to detect obvious damage, wear or other conditions which may render it unsafe. Equipment identified to be faulty needs to be withdrawn from service and either Versatile Technology or qualified personnel contacted to arrange repair or disposal. In accordance with AS3760:2001, the equipment must be subjected to: • Visual Inspection • Protective Earthing test • Insulation Resistance test • Documentation of all tests Frequency We recommend protectively earthed equipment installed in a Factory or workshop be inspected every year. VERSATILE TECHNOLOGY EZ101C AUTOMATIC EZOBILITY GAUGE Safety 13 Part A: Equipment Electrical Safety Testing Procedure To ensure that a gauge does not become an electrical hazard to the operator, servicing agent or builder Versatile Technology, an electrical safety test must be performed on the gauge prior to commissioning and a test record must be completed and shipped to the customer. Test Equipment Required Insulation and Earth Resistance Tester. Lutron DI6200 or equivalent. Testing standards. Based on Australian Standards AS 3760:2001. Test Procedure Insulation Test Connect the Tester as shown in the following diagram. The tester applies 500 volts and measures the resistance between the mains circuit and the gauge earth, which is the gauge case. Record all results on Electrical Safety Certificate The Minimum Resistance allowed between the Active supply and case is 1 M. Note: If the resistance is below 5 M then the gauge should be serviced as there may be an electrical fault. VERSATILE TECHNOLOGY EZ101C AUTOMATIC EZOBILITY GAUGE Safety 14 Part B: Earth Resistance or Protective Earthing Test This check measures the resistance between the earth conductor and the external case and metal parts that may become live due to a failure of the internal wiring. Connect the Tester as shown in the following diagram. Test with mains switch both ON and OFF. Record all results on Electrical Safety Certificate. If a gauge fails the electrical safety test? In the event of a gauge failing any element of the electrical safety test the gauge should be immediately repaired. If this is not possible it should be segregated so that it cannot be used. Under no circumstances can a gauge be used without passing the electrical safety test. VERSATILE TECHNOLOGY EZ101C AUTOMATIC EZOBILITY GAUGE Safety 15 Electrical Safety Certificate This is to certify that the Versatile Technology gauge listed below was tested in accordance with AS3760:2001, “In Service Safety Inspection and Testing of Electrical Equipment” published by Standards Australia. Refer to the Electrical Safety section for guidance in checking electrical safety. Gauge Description Model Serial Number Date of Certification 1. Visual Inspection Refer Clause 2.3.2 of AS3760:2001 p12 All mains wiring in good condition, and inaccessible during normal operation. Mains cables properly anchored Electrical Voltage and Fuse rating plate fitted. Rating Plate Label Vac A Slo Blo FUSE All electrical warning labels fitted. Flash stickers on power module. Separate Earth stud / Earth lead longer than Active/Neutral. All controls, safety covers, guards and safety facilities are secured and in good working order 2. Protective Earth/Resistance Test Refer clause 2.3.3.1 of AS 3760-2001 p13 Resistance between Earth connector and exposed metal parts that may become live in the event of an internal insulation failure. The resistance shall not exceed 1 ohm. Test Result OHMS 3. Insulation Resistance Test Refer clause 2.3.3.2 of AS 3760-2001 p13 Resistance between live supply conductors and exposed metal parts with a 500Vdc applied voltage. Minimum Resistance 1 Mega ohm. Test Result MEGA OHMS 4. Affix label A signed and dated 'ELECTRICAL SAFETY' label to gauge passes in accordance with the above specifications. Tested By Signed VERSATILE TECHNOLOGY
