Optional Accessories Included in the Charger

This charger may have been outfitted with several optional accessories or option packages. To determine the options included (if any) refer to the cover page of the manual package. If the manual package that is included with the charger is no longer available, contact La Marche and provide the model & serial number of the charger to receive a list of the included accessories.

Features

➢ Microprocessor Controlled High Frequency Switch-Mode Technology
➢ Single Phase Wide Range Universal AC Input: 105 Vac – 264 Vac, 50/60Hz
➢ Complete Galvanic Isolation from AC to DC
➢ Soft Start, Short Circuit Protection, Over Voltage, Over Temperature Protection, Reverse Polarity, and Input/Output Transient Overvoltage Protection
➢ Four Stage Battery Charging Algorithms (Unique Lead-Acid, and HCAP algorithms)
➢ Automatic High Battery Cutout Protection

Battery/HCAP charging voltage is temperature compensated (temp-comp) when the remote temperature probe is connected to the remote temperature sensor (RTS) terminal with the correct polarity.
Temperature Compensation Coefficient (25°C Reference Temp.) & Compensation Range:

• Lead Acid: -3mV/cell/°C, from 0°C to +50°C
• HCAP: -6mV/°C in 12V mode & -12mV/°C in 24V mode, from -25°C to +70°C
• NiCad: Not available.

Protection

• Temperature Compensation
  With temperature compensation, the output voltage is adjusted according to the temperature to prolong the life of the battery or HCAP. The charger also detects an open or shorted external probe. When the temperature probe is not connected or defective, temperature compensation is disabled.

• High DC Protection
  If 24V DC battery is connected to the charger when 12V mode is selected, it will shut down in High DC protection. No damage will occur to the charger.

• Output Short Circuit Protection
  Short circuit protection is triggered when the battery voltage drops below 6V in 12V mode, or 12V in 24V
  mode. The output of the charger is then turned off to protect the circuitry. The charger output will self recover in 2 minutes in a soft start mode to charge the battery.

• Output Current/Overload Protection
  When demand exceeds 100% of rated DC output current, the charger limits the current and reduces the output DC voltage to protect the charger.

• Thermal Protection

Charger is protected from over-temperature. The charger will derate by 30% due to over-temperature when ≥ 70°C (internal). For extreme overtemperature situations, thermal shutdown is activated when ≥ 85°C (internal). In both cases, as the temperature returns to 60°C (internal), the full output capability is automatically restored. (Note: Thermal protection does not activate when the charger is operating at full output current & operating in a 50°C ambient.)

Installation

Mounting

When mounting the LME Spro, the location chosen for the charger should be within an ambient temperature range of -40 to 122˚F (-40 to 50˚C) with a non- condensing relative humidity no higher than 95%. The LMESpro should be mounted in an area free of flammable & explosive materials and away from drips, splatter, or moving parts.
To be mounted on a non-combustible surface. The LMESpro utilizes convection cooling with a heat-sink facing the mounting surface; mount in an upright position as shown in Figure 1 to promote convection air flow. Provide clearance for at least 6in (152mm) of free air must be maintained on the left/right sides, and at least 6” (152mm) top/bottom sides for cooling. Maintain 36in (914mm) or more of clearance at the front of the charger in order to allow for operation and maintenance. Install the LMESpro using appropriate hardware on the wall. When using multiple adjacent LME Spro chargers, do not mount them 1 above the other, mount them side-by-side with a minimum of 6” between them. Avoid mounting the LMESpro directly over another heat source.

Electrical Connections

Before beginning installation of electrical connections, ensure that all sources (AC & DC) are de-energized; verify that no voltage is present on the field wiring by using a voltmeter. Check that the source voltage and frequency match the charger’s specifications. Select field wire size using Table 1 below.

Table 1 – AC/DC & Ground Wire Size Minimum Requirements (All wires specified in the table are copper rated at 90 °C or 194 °F)

Wire terminal table

| AC Input Terminal Line-1, GND, N/L2| DC Output Terminal Pos & Neg| Remote Temperature Probe

+ + & – –

---|---|---|---
Minimum Recommended Wire Size *| 18Ga| 14Ga| Optional accessory supplied by La Marche. Temp probe includes correct wire size, pre-crimped ferrules, and is marked (+ + & – -)
Range of wire sizes which fit the LMESpro push-in spring terminals| 18ga → 14Ga stripped 18ga → 14Ga w/ferrule| 14Ga → 8Ga stripped 14Ga → 10Ga w/ferrule
Wire Strip Length (Inch”/mm)| 0.4” / 10mm| 0.6” / 15mm

* NOTE: These are minimum recommended sizes per La Marche Standards. The National Electrical Code (NEC) and Local Wiring Codes must be followed. 

The LMESpro utilizes spring-loaded push-in style connectors. It is recommended to use wire crimp ferrules on the AC & DC field wiring when installing the charger, however it is not absolutely necessary. Crimp ferrules will prevent wire strands from fraying near the connectors. Being spring-loaded, the connectors are highly resistant to vibration and do not require periodic torque checks as with a screw-terminal. See Figure-2.
To connect field wiring, you can simply push in the prepared conductors until fully seated. To make the wires easy to push-in, you may insert a small flat- head screwdriver tip into the rectangular opening above the wire entry to relieve spring-tension on the wire connection.

Figure 3 – Wire installation

To remove a wire connection (on a completely de-energized system AC & DC), insert a small screwdriver tip in the rectangular opening above the wire to release spring pressure, then pull the wire out. See Figure 3.

Figure 4 – Removing a wire from the connector

AC Input Connections

Check that the source voltage and frequency match the charger specifications. Select wire size using Table 1. Before connecting the Battery/HCAP and/or DC loads, Refer to Section 2.2 for the configuration instructions. For AC Terminal location refer to Figure 5.

• For AC systems with a line and neutral such as 120Vac service in North America, connect Line to the “L” & neutral to the “N”.
• For AC systems with “2-hot leads” or Line-1 & Line-2 such as 240Vac service in North America, connect Line-1 to “L” & Line-2 to “N”.
• All installations require the Ground terminal to be connected to the AC service Ground/Earth wire.
• All installations require 3-wire connections to the AC Input connector

Figure 5 – LMESpro AC/GND Connections

DC Output Connections

Select proper size for the DC wiring from the wire size from Table 1. If the distance between the charger’s DC output and the DC load exceeds 10 feet, use the Power Cabling Guide on Appendix B to minimize the voltage drop across the wire distance. Connect DC output wires with the correct polarity connection as shown in Figure 3 below.

Figure 6 – LME Spro Output/Temp Sensor Connections

CAUTION: When connecting the DC cables to the battery, be certain the positive terminal of the charger is connected to the positive battery terminal and the negative terminal is connected to the negative battery terminal.
CAUTION: Do not touch the charger while it is in operation or just after de-energizing the charger as the LMESpro heat-sink can become very hot during operation.

Remote Temperature Probe Connection

It is recommended to use temperature compensated charging with Lead-Acid & HCAPS, especially in environments having a wide temperature range. La Marche supplies optional remote temperature probes (RTS) in two lengths option 11W – 24ft and option 11Y – 100ft with crimp ferules already attached for connection to the charger, and a 3/8” dia ring-terminal for connection to the battery.

• Connect the crimp ferrule end of the RTS to the LMES pro. See polarity markings (++++ & – – – -)
• Connect the ring-terminal to the negative terminal of the Battery/HCAP.

Operation

All equipment is shipped from the factory fully checked and adjusted to factory default settings. Before connecting the battery/HCAP check with the battery/HCAP manufacturer for the correct voltage settings and adjust the dip switch setting configuration accordingly (refer to Section 2.2). Failure to match the charger settings with the connected battery/HCAP may damage or shorten the life.

Initial Setup

Before starting up the LMESpro, perform the following checks:

• Verify the input voltage and frequency of the power source match the ratings on the nameplate of the charger
• Confirm the LMESpro has been configured for the proper battery/HCAP being charged. Refer to Section 2.2
• Check that the battery/load voltage matches the DC output voltage on the nameplate of the charger
• Verify the AC circuit is capable of continuously supporting the full-load rated input current of the charger
• Verify there are no frayed strands on each of the wire connections after being connected Tug on each of the individual wires making sure none of the wires pull-out of the connector
• Read section 2 for Initial Setup to set the DIP switches to match the Battery/HCAP.
• Read and understand all safety precautions in the manual.
  Apply AC power to the input terminals of the LME Spro to start up the charger after setting the DIP switches for the desired application per 2.2.

DIP Switch Settings

The LMESpro output can be configured to account for various battery types and voltages. Use the table below to change the DIP switch settings on the charger. Charger has to be power cycled for dip switch setting changes to take effect.

Table 2 – DIP Switch Configuration Settings

1 indicates a switch is in the down position and 0 indicates a switch is in the up position. Refer to Figure 1 & Figure 2 below for examples.

Lead Acid – Four Stage Charge Curve

Four-Stage Battery Charging Algorithm: The LME Spro battery charger is designed with four stage battery charging algorithms to prevent overheating of the battery and extend the life of the lead acid battery. The four stages are: Bulk/Absorption/Float/Equalize. This four-stage algorithm allows the battery to be fully charged with less stress, preventing battery overheating, over gassing and reaching maximum battery life. It can also keep batteries in a fully charged state (known as “float”) indefinitely.
Bulk Charge: In this stage, the battery voltage has not yet reached up to absorption voltage and 100% of rated current is used to recharge the battery. Charger initiates this mode when the battery voltage is less than 2.1 Volts per cell for more than 90 seconds. Provides full current until the battery reaches 102% of its absorption voltage reference.
Absorption: When the battery has recharged to the Absorption voltage level, constant-voltage regulation is used to prevent heating and excessive battery gassing. The charger will hold the absorption voltage mode until the battery is determined to be fully charged. The absorption mode detects the full charge condition by either the current tapering down to 0.5 Amps, or 4-Hrs has elapsed in the absorption mode.
Float: After the battery is fully charged, the Charge Controller reduces the charging voltage to the float mode.
Equalize (NiCad and Flooded battery types only): The Charge Controller will equalize the battery for three hours. The Equalize charging mode raises the battery voltage above the standard absorption voltage. This process prevents electrolyte stratification and equalizes the individual cell voltages within the battery.

Figure 9 – Lead Acid Four-Stage Charge Curve

HCAP – Four Stage Charge Curve

Four-Stage HCAP Charging Algorithm: The LME Spro battery charger is designed with a four stage HCAP charging algorithm to prevent overheating and extend the life of the HCAP. The four stages are: Pre-Conditioning, Bulk, Absorption and Float. This algorithm allows the HCAP to be fully charged with less stress, preventing overheating, and reaching maximum HCAP life. It can also keep HCAPs in a fully charged state (known as “float”) indefinitely.
Pre-Conditioning: If the HCAP is being recharged from a level (< 6.1Vdc for 12Vdc nominal or < 12.2Vdc for 24Vdc nominal), the LMESpro uses a proprietary pre-conditioning algorithm to safely recharge the HCAP with minimal stress. The LMESpro will pulse the output current for various amplitudes and durations while monitoring the voltage response from the HCAP. As the HCAP is determined to be in a healthy state, the charge rate increases allowing the terminal voltage of the HCAP to climb more quickly. Once the sustained output of the LMESpro exceeds (6.1V for 12Vdc nominal or 12.2V for 24Vdc nominal), the Pre-Conditioning stage is complete, and the charger graduates to the Bulk Charge mode. (Note, in most applications, the HCAP wouldn’t regularly be discharged to a voltage that would invoke operating in the Pre-Conditioning mode).
Bulk Charge: In this stage, the HCAP voltage has not yet reached the Absorption voltage, and 100% of rated current is used to recharge the HCAP. The LMESpro provides full-rated constant-current until the HCAP reaches the Absorption voltage. This is where the bulk of the AH/WH capacity is restored.
Absorption: When the HCAP has recharged to the Absorption voltage level, constant-voltage regulation is used to restore the remainder of the AH/WH capacity as quickly as possible. The charger will hold the absorption voltage mode until the HCAP is determined to be fully charged. The absorption mode detects the full charge condition by either the current tapering down to 0.5 Amps, or 1-Hr has elapsed in the absorption mode.
Float: Once the HCAP completes the Absorption stage, the Charge Controller reduces the charging voltage to the float mode. The HCAP is fully charged when the floating current is near 0Adc; see the HCAP instruction manual for further details. The HCAP can operate continuously at the float voltage of the LME Spro. Both the absorption and float modes are temperature compensated when the optional probe is installed.

Table 3 – LED Indicators

Fault Indications and Alarms

OUTPUT HIGH DC: If a 24VDC battery/HCAP is connected to the LME Spro charger when 12VDC mode is selected, the charger will shut down in high DC protection. No damage will occur to the charger. The charger will restore its output once it reaches the recovery voltage. Refer to the table below for the high DC voltage shutdown and recovery voltages.

Table 4 – High DC Output Alarm Thresholds

Charger Mode Selected| High DC Shutdown Voltage| High DC Recovery Voltage
---|---|---
12V| 15.3V| 14V
24V| 30.6V| 28V

OUTPUT LOW DC: When the battery/HCAP drops below 6V for a 12V system or below 12V for a 24V system, it will cause the charger to turn OFF. The charger will turn on after 2 minutes in soft start mode to slowly charge the battery/HCAP.
OUTPUT SHORT CIRCUIT: When an output short circuit occurs, or output exceeds 15A, the FAULT LED will indicate. Remove short circuit and reset the AC power to resume normal operation.

THERMAL DERATING: The charger has an over-temperature de-rate; when ≥ 70°C (internal), the output current is derated by 30%. When the temperature falls to 60°C, full output capability is automatically restored.
THERMAL SHUTDOWN: For extreme overtemperature situations, thermal shutdown is activated when ≥ 85°C (internal). When the temperature falls to 60°C, full output capability is automatically restored. (Note: Thermal protection does not activate when the charger is operating at full output current & operating in a 50°C ambient.) AC FAILURE: If the AC Input is below 105Vac or above 264Vac, the charger will indicate AC Failure by extinguishing the AC ON LED, and illuminating the FAULT LED. The charger will automatically resume normal operation when the AC input fall within the specified input range.
Reset Button
Should a FAULT occur causing the charger to go into a Fault Protection mode, the charger will attempt to self recover within a few minutes. If you are in front of the charger, most faults can be cleared with the Reset Button on the face of the charger near the indicator LEDs without having to wait for the next automatic restart attempt. Invoke a reset by pressing the Reset Button for 0.5 seconds.
Example: If an output short-circuit is detected, the charger will protect itself; see section 2.6 Output Short Circuit.
Every few minutes the charger will automatically attempt to restart. If the short is still present, the charger will continue to attempt restart every few minutes, and only fully restore output when the short-circuit is removed. If a technician finds and removed the short-circuit, they can use the Reset Button to immediately see the charger output restored rather than waiting for the next automatic restart attempt.
The Reset Button may also be used to temporarily turn-off the output circuit of the charger. While the output circuit is off, please be aware that energy is still available inside the LMESpro enclosure, the battery or HCAP where it connects to the charger, and some energy is stored in the charger’s output filter capacitors accessible on the DC output terminals. If you’ve de- energized the charger output, and removed connection to the battery/HCAP, wait at least 30-seconds for the output filter capacitors to fully discharge before accessing the charger’s DC output terminals.

• Hold the Reset Button for 9-seconds to de-energize the output circuit.
• Hold the Reset Button for 9-seconds to re-energize the output circuit.

Figure 12 – LMESpro Reset Button
