Page 3: Introduction
Section 1 Introduction The VAS - 4 is a full-featured vacuum monitoring system. The system uses the latest in integrated circuit technology, which allows a compact design, accuracy and reliability. The VAS - 4 features both high and low vacuum detection, separate high, low and latch alarm relays, three digit display of vacuum in inches of Hg., LED status indicators and an analog output.

Section 3 Specifications Input Voltage: 90-265 VAC 50/60 Hz Alarm Relays: NO\NC Type 240V AC @ 5A Resistive Load 115V AC @ 5A General Use 30V DC @ 5A General Use Gas\Fluid compatibility: System includes a protection device that uses a chemically inert synthetic oil compatible with chlorine, sulfur dioxide, and ammonia gas.
Page 5: Operation Basics
Section 4 Operation Basics Digital Display The three-digit display represents the real time vacuum pressure in inches of mercury (inHg). Minimum vacuum equals 00.0 and the maximum vacuum reading, depending on altitude, is approximately 30.9 inHg. LED Indicators The VAS - 4 has four LED indicators; High, Low, Latch and Polarity. See Fig.
Page 6: Alarm Outputs
Alarm Relays The VAS - 4 has three alarm relay outputs. The alarm relays do not become active until the delay timer times out, which causes the latch alarm indicator to become active. The three alarm relays are general purpose and can be used for exterior alarms, load switching or phone monitoring.
Page 7: Opening Unit
Opening Unit Remove the four plastic screws to open the unit. The printed circuit board contains static sensitive parts, so the installer should wear a grounding strap when handling the board. Enclosure Mounting IMPORTANT: This unit contains two enclosures. The larger one contains the electronics (VAS - 4) and the smaller one contains the sensor.
Page 8: Installing Vacuum Hose
Vacuum Line and Reset Switch Connect your ¼” vacuum hose to the ¼" barb fitting attached to the protection device. The reset switch is prewired to the board reset terminals. Power and Alarm Wiring CAUTION: BE SURE POWER IS DISCONNECTED BEFORE HANDLING ANY WIRES.
Page 9: Low Level Adjustment
Low level Alarm The Low Level alarm is adjustable from approximately 0.0 to 15 inches of Hg. To adjust the low level, insert a screwdriver into pot R19 and rotate it to the desired level. MIN = 0 and MAX = 15 inches of Hg. NOTE: If you want to disable the low alarm, turn the pot counter clockwise until it stops.
Page 10: Analog Output
Analog Output The VAS - 4 has an analog output, which will allow the vacuum to be remotely monitored. The connection for this is located in the upper left section of the printed circuit board (see Fig. 1). Two spade lugs are provided for the connection.
