SAFETY CONFORMITY MARKING THE SAFETY CONFORMITY MARKING IS APPLICABLE ONLY FOR INSTRUMENT PROPERLY MARKED WITH ETL, CE OR SIMILLAR MARKING.
  • Page 5 When this Leak Test Instrument is part of a leak test system, it is the user’s responsibility to assure proper interface and maintenance for this instrument to utilize its measurement capabilities safely and accurately. This instrument should NOT be operated at a pressure greater than a maximum of 160 psig or full scale of the sensor, whichever is lower.
  • Page 6 IGLS as well as view, save, and analyze test data using a separate PC. The E2/VE2 includes a female 9-pin D-connector on the rear panel for connecting to a PC using a straight through RS-232 serial extension cable. The IGLS receives commands and data requests and returns data via a bi-directional RS-232 port.
  • Page 7 The E2/VE2 instrument typically functions as a standalone leak test. It is capable of automated leak testing - with or without automatic pressure control. When functioning as a conventional leak tester, the E2/VE2 controls isolation, quick fill and fill valves to fill and stabilize the unit under test (UUT) prior to measurement.
  • Page 8 NOTE: Mount and locate the E2/VE2 as close as possible to the UUT to minimize UUT connection tube length and volume. Larger volumes will slow system response to a given leak flow. The E2/VE2 controls internal Isolation, Fill, Balance and Test valves as well as optional external exhaust valve, clamp/seal valve and/or an electronic pressure controller.
  • Page 9 The E2/VE2 ethernet port does not support Power Over Ethernet (POE). NOTE: The E2 and VE2 use a 2A fuse for the power module (example: Buss PN: BK/GMC-2-R) and 500mA buss fuse for the E2 RD21 board (example: Buss: PN: BK/GMC-500-R)
