Section 1 Introduction
The 1500 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 1500 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 a analog output. The
high and low alarm levels are user adjustable along with a variable delay
timer. The enclosure has a NEMA 4X rating; therefore it can be mounted
outside. Applications include loss of chlorinating in water and wastewater
treatment, pool pump monitoring, automotive test equipment and many
others.
Section 2 Inventory

2. Sensor enclosure with oil based protection device.
3. Two watertight fittings used for running the power and alarm
wires from the control box to the alarms.
4. ¼” tube fitting attached to the oil based protection device.
5. Power cord.
6. Instruction manual.
7. Warning label attached to the oil based protection device.

Section 4 Operation Basics
Digital Display
The three-digit display represents the real time vacuum pressure in inches
of Hg. Minimum vacuum equals 00.0 and the maximum vacuum reading,
depending on altitude, is approximately 30.9 inches.
LED Indicators
The 1500 has four LED indicators; High, Low, Latch and Polarity. See Fig. 1
for their location.
High LED Indicator
This LED indicates that the vacuum pressure exceeds the preset High
Alarm set point.
NOTE: This indicator is real time, i.e., it does not wait for the delay timer to
time out.
Low LED Indicator
This LED indicates that the vacuum pressure is below the preset Low Alarm
set point. This LED indicator is also real time.
Latch LED Indicator
When either the high or low indicators are active, this starts the delay
timer. If the alarm is active longer than the preset delay time, then the
latch LED indicator will become active. This indicator stays active until the
manual reset button (see Fig. 2) is pushed. This indicator implies that either
an alarm has occurred or is still active. If the latch indicator is on and the
High/Low indicators are off, then an alarm condition has occurred, but is
not active now. If either the High or Low indicators are active, then this
represents that the alarm condition is still active.
NOTE: The High or Low alarm relays do not become active until the latch
alarm indicator is on.
Polarity LED Indicator
When this LED is on this indicates that the 1500 is measuring pressure. The
digital display shows this pressure in inches of Hg. pressure.
