3. PRODUCT INTRODUCTION
Model L40 is a low-cost, universal analog input meter which offers 65 user-selectable analog
input types and ranges. User-selectable input types are DC voltage and current, true AC RMS
voltage and current, process signals (4-20 mA, 0-10V), thermocouple (10 types, °C or °F),
RTD (6 types, °C or °F), NTC and PTC thermistors, resistance (0-10k or 0-100k ohms), and a
potentiometric input. The same meter handles all of these signal types with no need for a plug-
in signal conditioner board. The meter's universal power supply accepts voltages from 18V to
265V, AC or DC, so that power can be from AC in any country or from 24 Vdc. A non-isolated
excitation output of 15V, 30 mA or 5V, 20 mA can be brought out. The meter conforms to the
popular 1/8 DIN size standard and features four 14.2 mm (0.56") red LED digits. The display is
user scalable for all input types other than temperature.
The base L40, as shipped by Flex-Core, is set up so that a 0-400 Vac input reads 0-400. o
change that default range, pry off the meter faceplate, push out the electronics, and move one
or two jumpers depending on the range, as explained in this manual. Make software selections
using front panel keys after reassembling the meter.
Selectable software features add flexibility to this low cost meter. Programmable features
include five levels of display brightness, min and max capture, dual scaling selectable by an
external control input, a deadband around 0 for AC measurements, a moving average digital
filter, a "count by" function, hysteresis for alarm operation, a user-configurable fast access
menu, and selectable password protection.
Optional output boards can be plugged in at any time and provide additional flexibility:
•A first option slot accepts one of three available plug-in boards. These are a single 8A
relay board, an isolated active or passive 4-20 mA analog output board, and an isolated
Modbus RTU compatible RS485 serial data output board.
•A second option slot accepts an 8A relay board, which plugs into a first slot option
board if installed. For example, this allows an L40 to have and analog output and a relay
output, or to have two relay outputs.
Advanced standard features include:
•Front panel UP key configurable for fast access to alarm setpoints.
•Eco mode to reduce power consumption.
•Simplified scaling configuration.
•External contact closure control input with programmable function.
•Five user-selectable display brightness levels.

4. RECEIVING & UNPACKING
Your meter was carefully tested and inspected prior to shipment. Should the meter be
damaged in shipment, notify the freight carrier immediately. In the event the meter is not
operable, contact your seller and return the meter for repair or replacement. Please include
a detailed description of the problem.
5. SAFETY CONSIDERATIONS
Warning: Your meter was tested to conform to the safety requirements of CE 61010-1.
Use of the meter in a manner other than specified may impair the safety of the device and
subject the user to a hazard. Visually inspect the unit for signs of damage. If the unit is
damaged, do not attempt to operate.
Cautions:
•The instrument must be connected to a disconnect switch or a branch-circuit breaker,
which must be in a suitable location
•The instrument can be powered by 18-265 Vac/dc. Verify that the voltage to be applied is
within this range. This instrument has no On/Off switch. It will be in operation as soon as
power is connected.
•This instrument is rated for signals as high as 400 Vac. Signal lines for such high voltages
represent a safety hazard and should only be installed by a properly trained technician.
•Do not make signal connections or signal wiring changes while power is applied to the
meter or while high voltages are applied to signal lines. Always remove power from the
meter or signal lines before handling.
•To prevent electrical or fire hazard, do not expose the meter to excessive moisture. Do not
operate the instrument in the presence of flammable gases or fumes.
•This meter is designed to be mounted in a metal panel or a bench or wall mount style case.
The spacing around the meter and the ventilation must be sufficient to maintain the ambient
temperature at less than 50°C.
•Verify panel cutout dimensions, and mount according to instructions.
Symbols used
Caution (refer to accompanying documents) Earth (ground) terminal.
Caution, risk of electric shock. Both direct and alternating
current.
Equipment protected throughout by double
insulation or reinforced insulation.
Operating environment:
The meter is Class II (double insulated) equipment designed for Pollution degree 2.

8. Output & Control Module Overview
An Electronics Main Assembly is standard. It consists of a large horizontal Motherboard,
which includes a Universal Power supply for 18-265 Vac/dc, and which performs signal
conditioning and processing for all selectable signal types. Soldered to the Motherboard is
a vertical Display Board, which holds the meter’s LEDs and pushbuttons.
An Option 1 Board can plug into the Display Board. This can be a single 8A relay board, an
isolated active or passive 4-20 mA analog output board, or an isolated Modbus compatible
RS485 serial data output board.
An Option 2 Board can plug into the Option 1 Board if installed. This is another single 8A
relay board. For example, use of this second board allows an L40 to have and analog output
and a relay output, or to have two relay outputs.

9. Opening the Case and Setting Jumpers
The case has to be opened and jumpers need to
be placed to select signal types and ranges other
than the factory default setting of 400 Vac.
To open the case, unplug all screw-clamp con-
nectors. Use a flat-blade screwdriver to lift up and
unsnap the two tabs A that hold the top of the
front cover. Turn the case over and repeat for the
two tabs B that hold the bottom of the front cover.
The front cover will then come off.
Press on the large green connector in the middle
bottom of the rear of the case to push out the
electronics Main Assembly through the front of
the case. Do this carefully, so that any options
boards remain seated in their grooved slots in the
plastic case. This will facilitate reseating of the
Main Assembly.
Note that all boards fit into grooved slots molded
into the case. These ensure perfect alignment for
electrical connections. An Option 2 board plugs
into an Option 1 board if present. For assembly,
these two boards are first interconnected and
then slid into their grooves.
The horizontal Motherboard has a jumper pin
forest labeled S to select the signal type and one
labeled T to select the function of multi-function
input terminal 5. Refer to the illustration to the
right and to the next page to place your jumpers.
Also refer to the signal input sections of this
manual.
Park any unused jumpers in the no-contact
positions illustrated by arrows to the lower left.
Once jumpers have been set, reseat the Main
Assembly and snap the front panel back on. You
should hear a loud click as each tab is seated,
and there should be no more gaps between the
front cover and case. Re-attach the screw-clamp
connectors when done.
