Model Scope/General Description

The La Marche model MXHF is a high frequency battery charger designed for use in industrial applications. The

MXHF is offered with DC output voltages of 24, 36 and 48VDC with output currents of 60, 120 and 180ADC.

These chargers may be powered with 208-240VAC single phase or three phase. For 380-480VAC three phase

only.

Understanding the Model Number

The MHHF model number is coded to describe the options that are included. Find the model number on the

nomenclature nameplate of the charger. Then follow the example below to determine the configuration of your

battery charger.

*Charger Type is not required for chargers equipped with APC Module

1 Equipment Handling

1.1 Storing the MXHF

If the MXHF is to be stored for more than a few days after delivery, it should be stored within its shipping

container. The location chosen for storage should be within an ambient temperature of -20°C to +70°C with

a non-condensing relative humidity of 5 to 95%.

1.2 Placement of the MXHF

The preferred installation is where the charger(s) can be located on a table or shelf, protected against

accidental contact with the lift truck or its forks. The MXHF has rubber feet on its base for simple placement on

a table or shelf.

With the MXHF on a shelf the risk of

damage to the charger or battery cables

is greatly reduced.

Avoid just placing the MXHF on the

floor next to the lift truck.

2.2 Making the AC Input Connections

AC input configuration is done at the factory prior to delivery once a customer’s AC main has been verified. The

available inputs are listed in the table below.

The process has been simplified using the AC filter board which is mounted inside of the MXHF. Simply remove

the top cover to access the AC filter board, it includes mounting posts for bus bar selection and headers for

auxiliary power supply voltage selection. Follow three easy steps to verify or configure proper AC input for the

MXHF.

2.2.1 Bus Bar Selection

Configuring the Bus Bars on the AC filter board negates the need to rewire the AC inputs to the power modules.

Use an 8mm socket on the M5 hex head bolts to secure the Bus Bars in place. Unused Bus Bar connectors are

bolted to the internal rear of the MXHF cabinet.

2.4 Alarms

The MXHF includes comprehensive protection and alarm monitoring. The alarms are graded into Urgent and

Non-urgent alarms. Urgent alarms indicate a dangerous condition that immediately stops the charge cycle.

Non-urgent alarms are indicated on the LCD and are logged in the alarm log but do not actually stop the

charge cycle.

2.4.1 Charger Related Alarms

Main Switch <Urgent> shows the status of the front panel start/stop toggle switch.

Inlet Filter <Non-urgent> can give a warning as to when the inlet filter needs servicing but is not enabled by

default.

Low Mains <Non-urgent> gives an indication of variation in the input mains voltage without actually affecting

the ability of the charger to provide rated output. It might also indicate that a Power Module is being

overloaded.

Mains Fail <Urgent> a mains loss situation and the charge cannot proceed.

Non-Urgent Rectifier Fail <Non-urgent> there is a power module that is not providing output, the Charger is

still operating but redundancy has been lost. Reduced power output and longer charge time as a result.

Urgent Rectifier Fail <Urgent> if the number of power modules not providing output equals or exceeds the

setting for urgent module count in the PC application monitor tab then the charger will stop. If the urgent

module count is set to one then the Charger is configured without redundancy and a single fault will stop the

charge.

Rectifier Over Temperature <Urgent> normally related to a blocked filter, restricted exhaust air or

installation in an inappropriate location.

Configuration Error <Urgent> the Charger cannot meet the target current required by the controller even

with all fitted power modules operating. The configuration does not meet the limits set for a 10A or 15A mains

input hardware limited charger.

Output Fuse <Urgent> a blown fuse in nearly all cases is caused by connecting a reverse polarity battery to

the Charger. When a fuse is blown check all cells for a reversed cable connection, a common problem with first

charge of shift batteries that have not been previously tested in a lift truck. After replacing a battery or Charger

cable always check the polarity before plugging the battery into the Charger.

No Output Current <Urgent> the charger is not providing the expected output current. Generally related to a

premature disconnection of the battery, but also could be an incorrectly inserted power module.

Monitor ADC Fail <Urgent> the internal watchdog of the MPC35s micro-controller is indicating a major fault

and potential unpredictable behavior if the Charger is left running.

2.4.2 Battery Related Alarms

Over discharged Battery <Urgent> the battery is still under 1.9 V/C after 30 seconds of charge and indicates

a faulty battery that needs investigation.

Deeply Discharge Battery <Non-urgent> the battery initially is under 1.9 V/C but recovers within 30 seconds

of the charge cycle start, this alarm normally comes up when a battery is unplugged from the lift truck and

immediately plugged into the Charger.

Sulphated Battery <Urgent> the battery fails to complete a de-sulphation profile applied by the Charger

correctly and generally means that the battery requires attention.

Incorrect Battery <Urgent> the battery is inappropriate for the configuration of the charger and cannot be

charged without reconfiguring the charger to suit the battery.

Bulk Charge Timeout <Urgent> the battery has exceeded the maximum time allowed for the initial constant

current bulk charge phase. Could indicate a faulty battery or the charger configuration is not correct for the size

of battery to be charged. May need additional Power Modules added to the Charger.

Finishing Charge Timeout <Non-urgent> the battery has exceeded the maximum time allowed for the

finishing part of the charge cycle. Generally not a problem and indicates the battery did not quite perform as

expected. Not uncommon with new batteries that are still cycling up to full capacity (allow 10 cycles) however if

the alarm is a regular occurrence it needs investigation and possible adjustment of the charger or service of the

battery.

Battery Disconnected <Urgent> the battery has been unplugged before charge cycle has complete. This can

damage the battery connector and increase risks of battery explosions as sparks around batteries at their top of

charge whilst gassing can be very dangerous. If the battery needs to be disconnected mid cycle, the toggle

switch must be first set to STOP. This will stop the charge and log a partial cycle in the charge log but allows

safe disconnection of the battery.

Reversed Battery <Urgent> a battery with it’s plus and minus cables reversed has been connected to the

charger. Generally this will also cause an output fuse alarm and the need to replace the chargers DC output

fuse(s). Such a situation is not covered by warranty as new batteries should always first be checked for correct

polarity BEFORE plugging onto the lift truck or a charger.

Minimum dV/dt <Non-Urgent> details the change in battery voltage over time. The alarm occurs when the

change in voltage exceeds the value set in the profile settings. This alarm also indicates the termination of a

successful charge.

Maximum Cell Voltage <Non-Urgent> occurs when the voltage per cell exceeds the value set in the profile

settings. Typically 2.7 V/C for lead acid batteries.

Batt Over Temp – Start <Urgent> occurs when the battery temperature measured before a charge profile

starts exceeds the value set in the controller settings. This alarm will not allow the charge profile to continue.

Batt Over Temp – Charge <Non-Urgent> occurs when the battery temperature measured during a charge

profile exceeds the value set in the controller settings. This alarm will allow the charge profile to complete.

+dI/dt <Urgent> occurs when the measured current in the constant voltage stage is rising instead of falling.

This alarm will terminate the charge profile.

Minimum Current <Non-Urgent> occurs when using an IU profile and the current in the constant voltage

stage falls below the value set in the profile settings. This alarm will not stop a profile and is considered normal

for some types of batteries.

EQ/Refresh Timeout <Non-Urgent> occurs when the time in a given stage of the equalize profile exceeds

the value set for that stage of the profile. This alarm will terminate the equalize charge but is not considered an

urgent alarm

Front View of the MXHF

3.2 Power Modules

The powerer modules are installed through the front of the housing and slide between steel guides. To access

the modules simply remove the inlet filter by removing to thumb screws holding the grill to the MXHF.

Each module is forced-cooled by two high-speed axial fans that are located behind the module’s plastic

faceplate. When installed in the charger, the modules draw ambient air through the front grill and filter and

force the warm exhaust air out the rear.

There are two type of power modules: Yellow module with AC input range of 175-300VAC single or three phase

and Green module with AC input range of 340-530VAC three phase only.

3.3 Optional Auto Profile Configuration (APC) Module

The Auto Profile Configuration Module (also called a battery module) stores configured information and

communicates with the MXHF through the battery cables. Once the battery is connected the APC module will

send the information to the MXHF charger. The MXHF will charge the battery using the information stored on

the APC module.

The APC mounts easily onto the top of the battery. This option gives

ability to charge different type of batteries using only one MXHF

charger. Each battery will require an APC module.

The APC module monitors battery voltage and temperature during

the charge process. A unique ID code can be assigned to the

module. An optional electrolyte can be fitted to the battery.

Rugged case construction resists impact, water and battery

electrolyte spills. Compact case size will not interfere with battery

watering, removal or lid closure.

3.4 Normal Operation

The following is a concise summary of knowledge necessary by the forklift user to correctly operate the charger.

The charger has been designed to require minimal set-up by the end-user and can be reconfigured only by

Authorized Representatives.

3.4.1 Pre-Charge Checks

Before plugging in a battery apply mains power to the charger, check that it is suitably configured for the

battery by checking the LCD display data and check that the battery and related cabling is in good condition. If

there is any exposed copper showing through the battery cable insulation or the insulation appears overheated

or burnt, DO NOT attempt to charge the battery.

Figure

Pow

er Modules

There are three status LEDs on the

faceplate:

• Red – No output

• Amber – Current limit

• Green – Operating

3.4.2 Stop/Start Rocker Switch

Connect the battery to the charger using the supplied cable and set the toggle switch to START, make sure the

big red LED lamp illuminates on the charger.

3.4.3 Charge Complete

A completed charge cycle is indicated by the big green LED lamp on the charger being illuminated.

3.4.4 Fault indicators

A flashing big red LED lamp indicates a non-urgent alarm has occurred during the charge cycle. No action is

required unless it happens on every charge cycle. When both the red and green LED lamps flash alternately an

urgent alarm has occurred, the charge has stopped mid cycle, be aware the battery may be only partially

charged or not charged at all.

3.4.5 Equalize Next Cycle

Before a charge is started it is possible to manually set the controller to perform an “Equalize Charge” at the

end of a normal charge cycle. The battery however will need to remain connected following the completion of

the normal charge until the equalize lockout time has expired, normally 4 hours. If the battery is unplugged

before the lockout expires the request for Equalize will be cleared.

To enable Equalize Charge for the next cycle, using the buttons on front panel of the charger perform the

following:

• Press the UP button twice to select the “Eq. Next Cycle” function

• Push ENTER to bring up “Disabled”

• Push UP to select “Enabled”

• Push ENTER to accept the change

• Push DOWN to select “Store”

• Push ENTER to store

• Push DOWN to return to “Connect Battery”

3.4.6 Battery Disconnection

Always set the rocker switch to STOP position before removing the connector during the charge cycle to avoid

damage to the poles of the connector and creating sparks in the vicinity of a gassing battery. The connector

should NEVER be unplugged during a charge cycle without setting the rocker switch to STOP position.

If the charge cycle is complete and the charger is not putting out heavy current the connector can simply be

unplugged without setting the rocker switch to STOP position. This will initiate an Auto Start option.

3.5 LCD Display

3.5.1 LCD View in the Resting State

During the resting state of the MXHF, either waiting

for the battery to be connected or the rocker switch to

3.7 MPC35 Controller Module

The MPC35 controller module provides the overall intelligence of the MXHF. It is the job of the controller to tell

the power modules how to correctly charge a battery. The controller must be configured to match a certain

battery before the charger can be used.

To understand the software element of the MXHF it should be explained that there are two separate software

components to the charger. First there is a Firmware (FW) which is embedded code that is loaded into flash

memory in the micro-controller chip in the MPC35 controller module. FW controls all the functions of the

charger. Second is the PC software that runs on host Windows computer and communicates to the MPC35 via a

USB connection. The PC software is called “Charger Interface” and provides necessary interface to read the

configuration, status, alarm logs and charge logs of the MXHF. If Automatic Profile Configuration (APC) module

is used, the APC configuration can also be read by the software.

There is no need for loading the FW as this is done at the factory during final test of the controller. However

should there be the need to adjust the function or add new features to the MXHF, the Charger Interface

software can be used to “Bootload” new FW into the controller.

3.8 Charger Interface Software

Note: Charger Interface software is not required to be used in order for the MXHF to fully operate. The “Read-

Only” version of the software may be provided to the customer for analysis purposes upon request. It is

intended to be used by technicians for troubleshooting, monitoring and retrieving alarm and charge logs.

3.8.1 System Requirements

Charger Interface software has the following minimum system requirements:

• Microsoft XP (SP3) / Windows Vista / Windows 7 / Windows 8

• Microsoft .NET Framework

• USB 1.0/1.1/2.0

• Administrator privileges on the PC for installation

3.8.2 Installation

Ensure the minimum system requirements are met before installing the Charger Interface software. The

software installer may be supplied on a CD, USB flash drive or other method. Locate and run the software

installer file. Follow the installer prompts to complete the installation. After installation a desktop shortcut will be

created. Power on the MXHF and connect the charger to the PC with a USB cable.

3.8.3 Operator Access Level Control

An incorrectly configured charger can cause irreversible damage to the batteries. For this reason Charger

Interface software employs a three-level access control. The three levels are:

• Read Only Access (Customer)

Read charger status, charger configuration, start and delay times, and alarm and charger logs. Viewing the

configuration of an attached APC module is also available.

• Configuration Access (Authorized Representatives)

Charger configuration settings can be modified using pre-defined template settings. The settings include:

Battery voltage, battery type, amp-hours and battery module (APC) enabling option.

• Advanced Access (Factory only)

Allows advanced control over the charger and battery module functions.

3.8.4 Charger Interface Tabs

Charger Interface software displays various charger data in a series of tabs within the main window. Some tabs

such as the Monitoring Tab are undocked by default. These tabs may be docked to the main window by double-

clicking the tab title bar.
