SECTION 1 – PRODUCT DESCRIPTION
1.1 GENERAL SYSTEM OVERVIEW
The basic function of the Model LC1000 Alarm console is to provide both audible and visual
warning alarms at the occurrence of high, low, or leak conditions: typically via float switches, or
any tank mounted sensing device that transmits an alarm condition by opening or closing dry
switch contacts. The LC1000 may also be used as a non-intrinsically safe remote alarm panel for
any system that provides a dry contact relay output to represent a specific set of conditions. The
console is powered by 120 VAC and provides 1 to 4 input channels each with a corresponding
light. Each input consists of a pair of intrinsically safe terminals for wiring to field mounted
switches. The intrinsically safe inputs allow mounting the switches in explosion hazard
environments without requiring additional protective barrier components in the wiring runs. For
every input, there is a single dry contact relay output that can be used to signal a remote alarm
device or control an external electrical device, such as a solenoid valve, up to 3A @ 120 VAC.

1.2 CONTROL CONSOLE DESCRIPTION
The console is housed in a NEMA 4X (weather tight/corrosion resistant) FRP (fiberglass
reinforced plastic) enclosure for mounting in the non-hazardous area. Each unit operates on 120
VAC power and provides from one (1) to four (4) intrinsically safe alarm channels for monitoring
up to four independent sensing points. The electrical energy output at each channel is 12 VDC at
15 mADC maximum, and is zener barrier protected. Bright red alarm LEDs, one for each channel,
and a horn are mounted to the enclosure cover.
Each alarm channel is equipped with a 1 Form C output relay, totally isolated from the sensor
inputs, rated for 3A@120VAC, for controlling external devices such as pumps (indirectly), valves
or remote alarm annunciators. All field wiring is made through pressure-type terminal blocks
enclosed under metal barriers to separate the power from the intrinsically safe wiring. Figures 1-2
and 1-3 illustrate the standard LC1000 outline, mounting flange locations, and dimensions.
The console should be located in an area that is easily accessible to the personnel responsible
for operation and maintenance of the system. Use only dedicated conduit entries for their
designated purpose as specified in Figure 1-4. Metal conduiting is recommended and may be
required by local codes. All outdoor conduits must be watertight.
WARNING
Installation MUST be done by qualified personnel familiar with local wiring codes
and explosion hazard electrical safety practices. FAILURE TO COMPLY MAY
RESULT IN PERSONAL INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE.
WARNING
The console is designed for Ordinary Location, Non-Hazardous installation only,
as defined by Factory Mutual (FM) and the National Electrical Code (NEC). DO
NOT install where flammable vapors may be present. FAILURE TO COMPLY MAY
RESULT IN PERSONAL INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE.

1. Remove the watertight CORD CONNECTOR supplied by sliding it off the sensor cable.
2. Thread the watertight CONNECTOR into the top of a 2" by 1/2" reducer bushing or monitor pipe
cap pre-tapped for a 1/2" NPT hole. (The use of any standard monitor cap from 2" to 4" pipe size
is recommended. The cap or reducer bushing IS NOT SUPPLIED with the sensor and must be
provided by the installer. A 2” (SK2) or 4” (SK4) Sensor Cap Kit can be ordered separately from
Pneumercator).
3. Measure the "MOUNTING HEIGHT" from top to bottom of monitoring pipe.
4. Feed the sensor cable through the watertight CONNECTOR from the BOTTOM SIDE of the
REDUCER (or CAP) fitting to a cable length suitable for the MOUNTING HEIGHT; or to allow
sensor to rest on the monitor pipe bottom; or as required by local codes. Cable may be cut or
extended to proper length.
5. Re-tighten the CORD CONNECTOR to fix the sensor cable length.
6. Mate the REDUCER or CAP to the top of the monitor pipe. Tighten the CONNECTOR to ensure
a WATERTIGHT SEAL.

2.5 LEAK SENSOR INSTALLATION IN FIBERGLASS TANK ANNULUS
The annular space of fiberglass tanks can be fitted with either a DRY ANNULUS type sensor, model
LS610 (Figure 1-6), or a WET RESERVOIR sensor model RSU800 (Figure 1-8). The wet reservoir is
also referred to as the HYDROSTATIC METHOD. Check the specific design drawings for the job, or
choose the type sensor desired from Figures 1-6 or 1-8. Install LS610 sensor per Figure 2-5 or the
separate document covering the RSU800: Bulletin 134.
Instructions per Figure 2-5, DRY ANNULUS SENSOR:
1. Calculate the sensor cable's MOUNTING LENGTH from tank size data so the sensor rests at tank
bottom; or use the following method.
Determine the cable's MOUNTING LENGTH by
adding the cable measurement M from the table at
the right to the RISER HEIGHT. Mark the cable at
that length. DO NOT CUT THE CABLE.
2. Remove the watertight CORD CONNECTOR
supplied by sliding it off the cable.
3. Thread the CONNECTOR into the top of a 2" by
1/2" reducer bushing or riser pipe cap pre-tapped
for a 1/2" NPT hole. (The use of any standard
monitor cap from 2" to 4" pipe size is recommended.
The cap or reducer bushing IS NOT SUPPLIED with
the sensor and must be provided by the installer. A
2” (SK2) or 4” (SK4) Sensor Cap Kit can be ordered
separately from Pneumercator).
4. At riser top, attach the annular space PULL CORD (this is part of the tank supplier's pre-installed
accessories) to the sensor's PULL HOLE.
5. Pull the free end of the PULL CORD out of the riser while feeding the sensor into the riser and
through the annular space until the sensor is at the bottom centerline of the tank. The MOUNTING
LENGTH MARK should be about 5 INCHES above the open riser. Adjust its position as necessary
and, without disconnecting the PULL CORD, coil its excess inside the riser pipe.
6. Feed the sensor cable through the BOTTOM of the riser cap (or bushing), and through the CORD
CONNECTOR while positioning cap over the riser pipe. Mate riser and cap.
7. Tighten CONNECTOR over the cable to ensure a WATERTIGHT SEAL.
8. Complete the wiring installation in accordance with Section 3.

2.6 OTHER DRY CONTACT FLOAT SWITCHES
The LC1000 has the electrical ability to read the continuity state of any dry contact sensor. As such,
this system will support a variety of sensors from various manufacturers. However, your local
regulations may not permit this combination as the LC1000 has not been specifically approved for
use with sensors not manufactured by Pneumercator. Please consult with your local regulators and
with Pneumercator to discuss the compatibility of your particular sensor with the console and

LC1000 INSTRUCTION MANUAL WIRING
SECTION 3 WIRING INSTALLATION AND DIAGRAMS
3.1 PC BOARD LAYOUT AND SETUP
The LC1000 Series includes either one (LC1001/LC1002) or two (LC1003/LC1004) PC boards
within the enclosure. These PC Boards will be setup at the factory to match the sensors provided
on the order. If you have two PC Boards in a single enclosure, they are considered to be a board
set. This is due to the fact that both boards are interconnected via a set of wires behind the PC
Boards. Do not make any attempts to remove these wires as they contain live voltage and will
also void the system warranty. All repairs to the boards must be performed at the factory.
The need may arise to reconfigure the PC Boards to accept normally open or normally closed
sensors. This can be accomplished by changing the setting of a series of jumpers or shorting
blocks. Each jumper is capable of shorting two pins together on the PC Board. A jumper location
on the PC board contains three pins with each pin being identified by a single letter. The table in
Figure 3-1 lists the two pins for each jumper location that must be shorted in order to achieve
normally open or normally closed operation for the entire PC Board. You cannot configure the
inputs individually. You can, however, configure each PC Board individually so that one PC Board
can be set for normally open operation while the other PC Board is set for normally closed
operation.
If normally closed inputs are selected, then you have also automatically enabled failsafe relay
mode. Failsafe relays are considered to be in their normal state when the relay is energized and
in their alarm state when the relay is de-energized. This is particularly useful if you are using a
remote alarm or monitoring system. If the LC1000 is powered off, blows a fuse, or is otherwise
out of service, the remote panel will see the relay state as being in alarm alerting local personnel
of the situation.
When acknowledging the internal LC1000 horn by pressing the integrated Reset button, you are
not changing the state of the relays from alarm to normal by default. You can, however, setup the
LC1000 so that pressing the Reset button also returns the relay to its normal state. This is usually
desired if you are connecting a remote alarm system. If this functionality is required, you will need
to cut a single jumper wire on the PC Board for each channel, as required. Since you are cutting
a jumper wire, this process is not field reversible. Make sure that this functionality is desired on
the selected channel before cutting the jumper wire. The P-R jumper wire would need to be cut
for channel 1 and the S-T jumper wire for channel 2.
An optional Autosilence (-ASC) feature is available on the LC1000 to silence the integrated horn
after a time delay. This feature is typically identified on both the silver foil label on the left-hand
side as well as on the front panel label. You may also identify whether the system has this feature
or not by identifying the PC Board(s) within the enclosure. If there are components at both the
JP7 and R14 locations as illustrated on the next page, then you have a board equipped with this
feature. The presence of a jumper at JP7 enables the feature whereas R14 is an adjustment used
to set the time delay from approximately 30 seconds (fully counterclockwise) to 3 minutes (fully
clockwise).

RSU800 CLOSED
Note 1: The LS600LD Series is shipped from the factory as normally open unless otherwise noted.
This sensor’s normal state is field reversible. Simply remove the E-clip from the bottom of the
sensor and then remove the plastic cap. Remove the float and flip the float upside-down and
reinsert the float into the bottom of the sensor. Reinstall the plastic cap and E-clip and the sensor
will now operate as a normally closed sensor.
Note 2: The LS600 defaults to the normally open OPERATIONAL state unless otherwise
specified. The operational state differs from the dry state in that the dry state is with the float in
the down position whereas the operational state varies for a give float. The Overfill (Gray), High
High (Violet), High (Blue), and Pump Stop (Red) floats are operationally down or dry. The Pump
Start (Orange), Low (Yellow), and Low Low (Brown) floats are operationally up or wet. Keep this
in mind when deciding whether the LC1000 input state is open or closed for a particular sensor.
Also keep in mind that it is possible, with factory guidance, to reverse the state of most LS600
floats. See Bulletin 193 for complete details on this particular sensor model.

LC1000 INSTRUCTION MANUAL WIRING
CAUTION
Sensors connected to the LC1000 are usually installed in explosion hazard areas
typical of hydrocarbon fuel tanks. For these applications, it is CRITICAL that
electrical conduit and wiring be installed by qualified installers familiar with all
provisions of the National Electrical Code relating to equipment intended for use
in EXPLOSION HAZARD areas. The primary concern is to maintain physical
separation between intrinsically safe and non-intrinsically safe wiring by running
separate conduit attached to the control console at the designated knockouts.
ALL conduits carrying sensor wiring into the hazardous area MUST be fitted with
standard vapor seal-off fittings at all field junction boxes and again where the
conduit first enters the non-hazardous area. FAILURE TO COMPLY MAY RESULT
IN PERSONAL INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE.
3.2 SYSTEM WIRING
Figures 3-2 and 3-3 are typical System Wiring Diagrams that must be followed when running
conduit and wires between the HAZARDOUS TANK area and the NON-HAZARDOUS CONSOLE
area. This follows FM and other codes for proper installation.
SENSOR WIRING INSTALLATION. Refer to Figures 1-4 through 1-8 for console conduit
openings and specific sensors that will be wired into the LC1000 system. Install wiring as follows:
1. Install 1/2" rigid conduit from all sensor areas to the LC1000 console.
CAUTION
All sensor wiring from the LC1000 console may be run in the same conduit. NO
OTHER WIRING MAY BE RUN IN THESE CONDUITS. NEVER RUN POWER WIRES
IN THESE CONDUITS. FAILURE TO COMPLY MAY RESULT IN PERSONAL
INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE.
2. At appropriate locations along the conduit runs (see Figures 2-3 through 2-5 and/or
appropriate sensor Instruction Bulletins) install watertight couplings and approved VAPOR
SEAL-OFF fittings.
3. At each sensor location install a WATERTIGHT ELECTRICAL JUNCTION BOX. Allow
enough room around the sensor tank fitting for proper installation of the sensor and all
conduit/junction box fittings, and for later removal if necessary.
4. Attach the conduit at the LC1000 console ONLY to the 1/2" conduit knockout designated for
Intrinsically Safe wiring (see Figure 1-4). Use NEMA 4 fittings for outdoor locations.

5. The alarm console is separated into two wiring sections, for each printed circuit board, by an
aluminum cover. The wiring and terminal block on the left side are intrinsically safe and are
physically separated from the AC power wiring on the right side. This separation must be
maintained. Remove the protective cover by loosening the two hold-down screws.
IMPORTANT - SEPARATION BETWEEN INTRINSICALLY SAFE AND
NON-INTRINSICALLY SAFE WIRING MUST BE MAINTAINED.
6. Pull properly marked 2 to 3 conductor wiring (depending on sensor configuration) for each
sensor through the conduit leaving at least 24 inches excess at both console and junction box
ends for final connections. The field wires must be resistant to hydrocarbon liquids; type THHN
or MTW, 22 AWG is recommended.
7. Fill all conduit VAPOR SEAL-OFF FITTINGS with approved filling compound and tighten all
conduit fittings.
8. Splice all sensor wires to the respective conduit wires at each WATERTIGHT JUNCTION
BOX. (See Bulletins 179 and 180 for a recommended procedure). Maintain correct
color-coding between wires.
9. Connect sensor wires to the LC1000 INPUT TERMINALS following Figures 3-2 or 3-3. The
terminal blocks may be removed for ease of wiring by pressing with your finger down toward
the conduit openings. Note that for multiple channel consoles, power need only be wired to
the right-hand circuit board. Maintain correct polarity between wires and respective terminal
points.
10. Properly dress all wires inside the wiring sections and re-install the protective aluminum cover
over the terminals.
11. Sensors should be logically identified as to location and type and recorded on the Sensor map
provided in this manual, SECTION 3.3.
Sensor wires are to be connected ONLY to the designated input terminals of the
INTRINSIC SAFETY compartment. DO NOT allow sensor wires to cross over into
the non-intrinsically safe section. FAILURE TO COMPLY MAY RESULT IN
PERSONAL INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE.
Relay output terminals are located on the NON-INTRINSICALLY SAFE side of the
console. ALL wiring to these terminals MUST enter through the designated
conduit opening. Refer to FIGURE 1-4. FAILURE TO COMPLY MAY RESULT IN
PERSONAL INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE.

3.4 INSTALLATION AS A REMOTE ALARM PANEL
The design of the LC1000 allows this system to be used as a remote alarm panel to another system
equipped with dry contact outputs. These outputs can be monitored by the LC1000 so as to generate an
additional alarm for the same condition as the main system has detected. If the LC1000 is used in this
application, then permanently remove the intrinsically safe (IS) cover by removing the two screws holding
down the cover. This identifies this particular installation as a non-intrinsically safe application. Do not install
intrinsically safe wires on an LC1000 without the IS cover installed.
A single pair of wires per signal would connect the main system via the dry contact output to the LC1000
on the Switch input.
All Pneumercator systems equipped with relay outputs are considered dry contact, or outputs without
power. Other equipment manufacturers may use powered relay outputs. Consult the system manufacturer
to determine if the system is equipped with outputs that are dry contact that can be used to represent the
desired alarm condition.
DO NOT CONNECT POWER TO THE DRY CONTACT SENSOR INPUTS OF THE
LC1000. FAILURE TO COMPLY MAY RESULT IN PERSONAL INJURY, PROPERTY
LOSS AND EQUIPMENT DAMAGE.
The LC1000 is equipped with relay outputs that can be used to signal another LC1000 as a remote alarm.
In that case, the primary or main LC1000 would need to have the IS cover installed and would, therefore,
be considered intrinsically safe. The second LC1000 would not be considered intrinsically safe and would,
therefore, need the IS cover permanently removed.
CAUTION
PAGE 27
LC1000 INSTRUCTION MANUAL OPERATION
SECTION 4 OPERATION
4.1 GENERAL
The LC1000 Alarm system provides three (3) functions when a field sensor experiences an alarm
condition: A light comes on, a horn annunciates and a relay changes state. The horn may be
silenced by pressing the RESET button, but the light will stay on and the relay will remain in the
alarm state as long as the field sensor remains in the alarm condition, e.g., high liquid level. After
the alarm condition is corrected, i.e., lowering the liquid level below the level switch setting, the
alarm light will extinguish, the relay will return to its normal state, and the horn will automatically
reset to the silent state. The behavior of the relay for the reset process can be changed to allow
the relay to be returned to the normal state upon acknowledging the alarm (See section 3.1). On
multiple sensor consoles, each input switch will actuate the horn and its respective light
independent of the other sensor's state or the prior state of the alarm console. NOTE: Each input
switch must be of the same normal state on each PC Board for proper operation. The TEST button
manually energizes the horn, all lights, and all output relays on the console. This is accomplished
by simulating all inputs as being in the alarm state. If all inputs are in the alarm state PRIOR to
pressing the TEST button, the TEST button will not have any function.
4.2 HORN CONTROLS
In addition to silencing the horn by pressing the "Reset" button, four other horn controls are
available:
Loudness Level - A louver on the horn face may be adjusted by hand to decrease the
output sound from about 86 decibels to about 50 decibels.
Automatic Silence (Optional) - A potentiometer on the PC board (see Section 3.1) allows
selecting a time delay interval after which the horn will silence automatically, without
pressing the "reset" button. This is an optional feature, designed by the Model Number
Suffix "-ASC." The time delay period ranges from a minimum of about 30 seconds to a
maximum of about 3 minutes. This feature can be disabled by changing a jumper setting
(see Section 3.1).
External Horn Reset - If it is desired to have the LC1000 also control and silence an
external, remotely mounted horn, this can be done by wiring the output relay contacts for
the selected channel in series with your external horn and its power source. In addition, a
PC board jumper must be removed (see Section 3.1). Note that implementing this feature
eliminates using the associated relay contacts for other control devices. Use an external
horn that is rated 2A@120VAC or less for this feature.
Horn Silence From a Remote Location - If it is desired to silence the LC1000 horn from a
separate location, this can be done by running a pair of wires from your own normally
open, momentary pushbutton switch in parallel with the LC1000 RESET switch normally
open contact positions. Separate power is not required.
PAGE 28
LC1000 INSTRUCTION MANUAL TROUBLESHOOTING
A
SECTION 5 TROUBLESHOOTING
5.1 GENERAL
The On/Off switching control operation of the LC1000 makes it simple to test and troubleshoot
the system. Pressing the TEST button performs a functional test of the horn, all indicator lights
and all relay contacts. Before pressing TEST, make sure all externally controlled devices are on
standby or are accordingly addressed. Also, you will need to make sure that at least one input is
not in alarm for the Test button to properly simulate all inputs being in alarm.
The input wiring can be disconnected to check the functioning of the inputs as well as to allow
access to the wiring to perform a continuity test. If the wiring is disconnected and the LC1000 is
configured for normally open operation, all of the lights are expected to turn off. With normally
closed operation, the lights would be expected to come on. Using a jumper wire, you can simulate
an open and closed state across the input to determine that it is functioning by observing the
system lights. You may also take a DC voltage measurement across the input to verify the
presence of approximately 12VDC. If there is no voltage present with the wires disconnected from
the input, then check the internal fuse with your ohmmeter while the AC power is shutoff from the
circuit breaker.
To check the operation of the LC1000 from a field wiring location, e.g., at the field sensor location,
simply place a jumper wire between the field wire pair for normally open sensors, or open the field
wire pair for normally closed sensors. This action will set the LC1000 into the alarm mode. If this
works as expected, then you can assume that the wiring is intact.
All sensors can be tested with a continuity meter. By manipulating the float by hand, you can
change the state of the sensor to be detected by the meter.

LC1000 INSTRUCTION MANUAL MAINTENANCE
SECTION 6 MAINTENANCE/TESTING
6.1 CONSOLE
The operation of the LC1000 lights, horn, and relays can be verified by holding down the TEST
button. The TEST button causes all alarm conditions for the system to go to the alarm state. For
this reason, it is best to do this with at least one alarm condition in the normal state otherwise your
horn will not activate since there are no new alarm conditions detected. If the lights and horn do
not activate as expected, follow the troubleshooting instructions found in Section 5.
There are no consumables for the LC1000 therefore no parts need to be changed on a regular
basis. Refer to section 5 for a list of service parts available to repair the LC1000.
6.2 SENSORS
The sensors themselves cannot be tested from the front panel of the LC1000. Instead you must
remove the sensor and manipulate each float by hand to simulate an alarm condition. The only
exception to this rule is in the case of an LS600 equipped with a test lever. This test lever allows
for the testing of the uppermost float, typically used as the overfill protection. See Bulletin 193 for
details on the LS600 Series sensors.
WARNING
Testing MUST be done by qualified personnel familiar with local wiring codes
and explosion hazard electrical safety practices. FAILURE TO COMPLY MAY
RESULT IN PERSONAL INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE.
It is generally considered good practice to ensure that your system is fully operational on an
annual basis. For thicker or more viscous liquids, you may want to inspect the system more
frequently to confirm that no product has built up on the sensor so as to interfere with its proper
operation. Your local regulations may require testing based on a different schedule so consult
with your regulator/inspector for the frequency of testing needed for your application.
