THIS UNIT SHOULD BE WIRED TO A GROUND FAULT
RECEPTACLE.
CAUTION: HIGH VOLTAGE COULD EXIST INSIDE THIS UNIT.
DISCONNECT ALL POWER BEFORE INSTALLATION.
2.1 OPENING UNIT
Remove the four plastic screws to open the VAC 2000. The printed
circuit board contains static sensitive parts.
THE INSTALLER MUST WEAR A GROUNDING STRAP WHEN
HANDLING THE BOARD.
2.2 ENCLOSURE MOUNTING
IMPORTANT: This unit contains two enclosures. The larger one
contains the electronics and the smaller one contains the sensor.
The two enclosures are permanently connected together by a low
voltage wire. The sensor enclosure contains an oil-based protection
device that is filled with a special fluid. The protection device
has a cap over the 3/8" fitting to prevent the oil from leaking out
during shipping and installation.The sensor enclosure must be
mounted in an upright position to prevent the fluid from
leaking out. Once the unit is securely mounted in an upright
position, the cap over the 3/8" fitting can be removed.
The recommended mounting method for the VAC 2000 is to use
the four mounting holes located where the 4 plastic screws are
that hold down the lid. Use the box as a template for mounting.
(See Drawing 2).
NOTE: THE VAC 2000 SHOULD NOT BE MOUNTED WHERE
SUNLIGHT CAN DIRECTLY ENTER THE TRANSPARENT COVER.
2.3 VACUUM LINE AND RESET BUTTON
Connect the vacuum tubing to the fitting attached to the protection
device. The reset button is prewired to the board reset terminals.
2.4 ANALOG OUTPUT
The VAC 2000 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 Drawing 1).
Two spade lugs are provided for the connection. These are
labeled "GND" for ground and "OUT" for the output. The output is
capable of sourcing 0 to 3 VDC or 0 to 3 mA. If a 4 to 20 mA loop
is required, a signal conditioner can be used to convert the
output.These are available from many sources.

1.0 BASIC INFORMATION 2.0 INSTALLATION

2.5 POWER AND ALARM WIRING
CAUTION: BE SURE POWER IS DISCONNECTED BEFORE
HANDLING ANY WIRES.
WARNING: Improper wiring to this unit can damage unit and
could cause serious bodily injuries.
See Drawing 1 for typical electrical wiring. Connect 115/240V AC
to the connector location labeled GND, L1/N, L2.
NOTE: A surge arrestor is recommended on the AC power line to
prevent damage from lightning strikes or other power surges.
Be sure the relay specifications are not exceeded. The relay
outputs are labeled HIGH ALARM, LOW ALARM and LATCH
ALARM. Remember the latch alarm will stay active until the reset
button is pushed.
NOTE: NO = Normally open contact
NC = Normally closed contact
COM = Relay common
The VAC 2000 comes preset at the following default levels:
Delay: 50 Sec.
Low Alarm: 5 inches Hg
High Alarm: 25 inches Hg
The following is a procedure for changing these values. See
Drawing 1 for the location of the adjustment potentiometers.
CAUTION: HIGH VOLTAGE EXISTS INSIDE THE UNIT.
3.1 DELAY ADJUSTMENTS
The delay time is adjustable from approximately 1 second to 100
seconds. To adjust the delay, insert a small screwdriver into pot
R24 and rotate until the desired delay is achieved.
3.2 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.
3.3 HIGH LEVEL ALARM
The high level alarm is adjustable from approximately 15 to 30
inches of Hg. To adjust the high level, insert a screwdriver into pot
R16 and rotate it to the desired level. MIN = 15 and MAX = 30
inches of Hg
NOTE: If you want to disable the high alarm, turn the pot clock-
wise until it stops.
3.4 ALTERNATE METHOD FOR ACCURATE
HIGH/LOW LEVEL ADJUSTMENT
If a high degree of accuracy is required, then use the procedure
in the following example.
EXAMPLE:
Desire a high level alarm at 26.3 inches of Hg.
1. Adjust your vacuum level until the digital readout reaches 26.3.
2. Rotate the high level alarm pot full counterclockwise.
3. Rotate the high level pot clockwise slowly until the high level
LED comes on. This represents the correct adjustment for 26.3
inches of Hg.
This method can be used for low level adjustment, except the
rotation of the pot is reversed.
3.5 MAINTENANCE AND CALIBRATION
Once the VAC 2000 has been in operation for approximately one
week, the unit should be checked for the correct zero reading.
This is the reading when no vacuum is present. Ideally, the zero
reading would be 00.0. However, due to the ambient temperature
or if the vacuum line is attached, some variation is normal. If the
zero reading is over 00.7, then an adjustment may be needed.
The zero adjustment pot is located in the upper right hand corner
of the board (See Fig. 1). Slowly turn this pot to get the zero
reading as close to 00.0 as you can without the polarity LED
coming on. This will end the zero calibration.
Once a month the system should be functionally tested. This testing
should include all relays, LED indicators, delay timer and vacuum
level accuracy. To perform this test, adjust your vacuum level up
and down to cause the high and low alarms to engage. The delay
timer and reset can also be tested in the same manner. At this
time, inspect the board for any corrosion or loose wires. If corrosion
is present, check all fittings for a snug fit. Corrosion can only
be removed by a trained technician. The sensor is made from
Stainless Steel and is sealed from any chlorine and the oil protection
fluid. The outside of the enclosure can be cleaned with warm
water and a damp cloth.
DO NOT ATTEMPT TO CLEAN ANY CORROSION FROM THE
BOARD. HIGH VOLTAGE EXISTS ON THE BOARD.

3.0 SET UP AND CALIBRATION

4.1 DIGITAL DISPLAY
The three digit display indicates the working vacuum level in inches
of Hg. Minimum vacuum equals 00.0 and the maximum vacuum
reading, depending on altitude, is approximately 30.0 inches.
4.2 LED INDICATORS
The VAC 2000 has four LED indicators: High, Low, Latch and
Polarity. See Drawing 1 for their location.
A) HIGH LED INDICATOR
This LED indicates that the vaacuum level exceeds the pre-
set "high alarm" set point.
NOTE: This indicator confirms the existence of a high vacuum
condition prior to the activation of the timed delay alarm.
B) LOW LED INDICATOR
This LED indicates that the vaacuum level is below the pre-
set "low alarm" set point.
NOTE: This also activates prior to the timed delay alarm.
C) 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, the latch LED indicator will activate. It stays
active until the manual reset button (See Figure 2) is pushed.
This indicator verifies that either an alarm occurred or is still
present. If the latch indicator is on and the high/low indicators
are off, an alarm condition has occurred, but has been
corrected. If the high/low indicators are lighted, the alarm
condition still exists.
NOTE: The alarm relays do not become active until the latch
alarm indicator is on.
D) POLARITY LED INDICATOR
When this LED is on, this indicates that the VAC 2000 is
measuring pressure. The digital display shows this pressure
in inches of Hg pressure.
4.3 ALARM RELAYS
The VAC 2000 has three alarm relay outputs. These do not
become active until the time on the delayed timer has run out.
This 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.
NOTE: Do not exceed relay specifications.
A) HIGH ALARM RELAY
This relay becomes active from a high alarm condition only
after the time on the delayed timer has run out. This relay
remains active as long as the alarm condition exists. Once
the alarm condition is corrected, this relay becomes inactive.
B) LOW ALARM RELAY
This relay becomes active from a low alarm condition only
after the time on the delayed timer has run out. This relay
remains active as long as the alarm condition exists. Once
the alarm condition is corrected, this relay becomes inactive.
C) LATCH ALARM RELAY
When either the high or low alarm relays become active, the
latch alarm relay also becomes active. This is indicated by
the latch alarm indicator. This relay stays active until the
manual reset button is pushed (See Drawing 2).
NOTE: In some applications, special attention needs to be given
to the electrical hookup. If your vacuum source, under normal
operation is cycled on and off (as is the case when the vacuum is
created only when a well pump is operating), the 115V AC power
to the VAC 2000 should be switched on and off with the well
pump. This will prevent a low alarm condition when the pump is off.
