VS Series Helium Mass Spectrometer Leak Detectors
Section 1. Introduction to the VS Series
1.1 The VS Series Leak Detector
The VS Series is a wide-range Helium Mass Spectrometer Leak Detector, which is
comprised of a turbo molecular high vacuum pump, internal mechanical rough pump
(model VS PR02), internal scroll pump (model PD03), external mechanical rough pump
(models VS MR15, VS MD15, VS MD30+, VS BR15, VS BD15 and VS BD30+),
spectrometer tube, valve block, leak detector electronics, an operator interface (TFT-LCD
display with a touch panel and two hard buttons: TEST and VENT), and optional features,
including:
Wireless remote control that includes:
❑
❑
❑
Optional I/O PCB (P/N VSFLDIO).
❑
Models VS MR15x, VS MD15x and VS MD30+x include an optional two-wheel cart.
All models are available in 100/115 VAC and 230 VAC configurations (see Table 1-1 on
page 1-2).
The wireless remote control has the following capabilities:
RF communication between VS leak detector (Base Station or Host) and the Wireless
❑
Remote unit from the distance up to 100 m (300 ft).
Enter the VS leak detector unit into Test and Hold modes from the Wireless Remote
❑
unit keypad.
Read the VS leak detector unit's leak rate in a linear and logarithmic bar graph
❑
format with a numeric range indicator and System status in alphanumeric format on
the Wireless Remote unit LCD display.
Configure up to ten different VS leak detector units for wireless control by toggling
❑
through a MAC address list using one Wireless Remote unit.
The optional I/O PCB compromises:
Optically isolated parallel I/O (DB25 female connector with 12 output and 8 input
❑
lines) to use with an external PLC and should be powered by the user (+5-24 VDC)
via a cable with length less than 10' and provided by the user (see Appendix A.3.2
"I/O Connector" on page A-14).
