1.0 INTRODUCTION
The Magellan Powertronics MCRII Series single phase battery charger / DC power
system utilises phase controlled AC to DC conversion technique together with the
latest micro-processor hardware and software to produce advanced charging
systems suitable for Lead Acid, Nickel-Cadmium or Lithium Iron batteries.
The MCRII charger is a constant voltage type, with current limit and two voltage
levels: float and boost . The boost level is used to recharge the battery whilst the float
is used to keep the battery in a fully charged condition. For applications using sealed
Lead Acid batteries, the boost function may be disabled.
The boost mode can be initiated manually or automatically. The manual boost is
initiated by depressing the momentary boost button and the status is indicated on the
LCD display. The charger then remains in the boost for a period of 0 to 24 hours
(selectable) after which it will automatically revert to float mode. The automatic boost
is activated if the current into the battery exceeds a pre-set limit for a pre-set time.
The automatic boost is also controlled by a boost timer (0 to 24H).

3.0 INSTALLATION INSTRUCTIONS
Install the battery charger in the allocated position and ensure that sufficient cooling
air is available for natural convection cooling.
3.1 CABLING
Refer to the Charger Schematic and Connection Diagram in the Appendix
1. Connect Single Phase 240V and earth to terminal X1 in accordance with
the schematic diagram. (Refer to "Charger Test sheet" for current demand
and size cable to suit).
2. Connect the battery temperature probes to the terminals X5 1, 2. The
details are given in the schematic drawing and the table provided in the
Appendix. Mount the temperature probe to the negative terminal of the
battery. Please also make sure that battery temperature probe is
connected correctly to terminal X5. Wrong connection of the battery
temperature probe will result in incorrect operation of the charger.
3. Connect the battery bank to the terminal X2. (Please observe polarity).
Note: If Impedance Test or Full Battery Test Facility options are included,
please connect terminal X2 (wire numbers 101 and 102) to the actual
battery terminals.
4. Connect load as per the schematic drawing.
5. Connect external alarm wiring (if applicable) as per schematic drawing.
3.2 INSTALLATION PRECAUTIONS
•The (optional) battery impedance connections (101, 102, 103 and 104
on the schematic), used with the optional Battery Impedance Test or
Full Battery Test, must be connected in parallel to the standard battery
connections, as in the schematic diagram.
•MCRII requires that the battery temperature sensor is connected to
operate correctly. If it is not connected, if it is shorted, or if the polarity
is reversed, the charger may not operate, as a safety precaution.
•The Common Alarm relay and optional Alarm Card relays are fail-safe,
therefore are energised under normal operating conditions, and de-
energised under fault conditions. This means that an N/C connection
will be open when no fault is indicated, and close on a fault condition.

4.0 CIRCUIT DESCRIPTION
See Charger Schematic drawing in the Appendix
The AC input voltage is applied to the power transformer (T1) primary winding via the
input EMI filter and the input Circuit Breaker CB1. Transformer (T1) galvanically
isolates the AC mains input from the DC output and converts the mains voltage into
secondary voltage of the required levels for the power bridge (BR1).
The half-controlled thyristor bridge operates in a phase control scheme to rectify and
regulate the output power. The unfiltered DC voltage produced by the bridge is fed to
the Inductor/Capacitor filter network (L1, C1) for smoothing. The filter reduces the
ripple content of the output DC to a very low level. The charger current is sensed by
the current shunt. A separate shunt senses the battery current for the purpose of
battery current limiting and display.
4.1 CONTROL AND MONITOR CIRCUITS
The control circuit monitors the output voltage and current and compares them with
set values; the thyristor conduction angle is then adjusted to ensure that the output
voltage and current are in accordance with the preset levels.
The control circuit is contained on three electronic circuit boards. The Interface Board
(A2) communicates with the MCRII Microcontroller Board (A3) via a 34-way ribbon
cable and carries out the following functions:
1. Buffers and filters and scales the incoming voltage, current and temperature
signals.
2. Buffers and level translate the control output to the SCR Firing Board (A1).
The Interface Board also contains an isolated +/-12V power supply. This power
supply is in turn supplied from two sources, a step-down control transformer with 18V
secondary and the battery. This ensures that the control circuit is powered even
when either the mains or the battery is absent. The control power is distributed via
the 34-way ribbon cable to the Microcontroller board.
The Microcontroller Board monitors the battery and charger parameters and
generates alarm signals which are used to drive the alarm LEDs and relays on the
relay board A4, if installed. A common alarm relay situated on the Interface Board

(A2) de-energises if an alarm condition is detected. The common alarm signal also
drives a buzzer located on the Microcontroller Board (A3). The buzzer sounds for any
alarm condition and will stay on for the duration of the alarm. The buzzer can be
muted by depressing the Mute button on the front panel.
The Microcontroller Board provides voltage and current control references to the
Interface Board via a D/A converter. These references are compared with voltage
and current feedback signals. The output signal from the error amplifier is fed to the
SCR Firing Circuit (A1) where it is compared with a reference ramp synchronised to
the mains. The output of the comparator then controls a high frequency oscillator to
fire the thyristors through a pulse transformer.
All metering functions are generated by the Microcontroller (A3) from filtered inputs
obtained from the Interface Board (A2). These signals are routed through the CPU’s
analogue inputs and are displayed on the graphical LCD display.

Cycling through these screens is achieved by operating the Mode/Ack switch on the
front panel. The display will automatically return to Screen 1 in 5 minutes if left on
Screen 2 to 5.
5.3 BOOST CHARGING BATTERIES
5.3.1 Manual operation
The boost charging circuit is achieved by pressing the Boost button on the front
panel. The system will then remain in boost mode until the internal boost timer
completes the preset boost cycle.
The boost mode can be terminated by pressing the Boost button again.
5.3.2 Automatic boost
Charging of the system commences if the battery charging current exceeds a
selected value for a preset period. Both the battery current value and the preset
period are user adjustable. (See User Programmable Set Point Instructions).
Automatic boost mode is terminated by pressing the Boost button.
5.4 BATTERY TEST
5.4.1 MODE 1: Battery Impedance Test
The Battery Impedance test calculates internal resistance within the battery by
drawing a high current pulse (approx. 50A, which does not indicate on front display)
and by monitoring the battery’s voltage drop.
5.4.1.1 PROCEDURE:
1) Momentarily press ‘BATT TEST’ button
2) Display goes automatically to capacity and Last ratio menu. Wait for 5-6
seconds for Impedance and Baseline mOhms to appear on the screen.
3) Repeat step 1 until Impedance mOhms shows a stable reading after multiple
trails (proximately 5 times).
5.4.1.2 First time or New Batteries:
After observing that the Battery Impedance is stable, hold Reset button for 6 seconds
to set the measured impedance as the baseline impedance. This is done to obtain a
reference impedance to compare with future impedance values. This baseline
impedance is now the reference for future impedance measurement and comparison.

When the difference between the measured impedance and the Baseline Impedance
is greater than 75% of the Baseline Impedance, the Battery Fail Alarm will be
activated.
5.4.2 MODE 2: Discharge Test
The Discharge Test operates by discharging the battery into a load that is connected
across the battery for 5 minutes. During this test, the charger voltage is lowered to a
preset value and the battery voltage is monitored to check that it does not drop below
the “Battery Discharge Threshold” Setpoint.
A Battery Fail alarm is activated if the battery voltage drops below “Battery Discharge
Threshold”. If the internal timer completes its cycle before battery voltage drops to
“Battery Discharge Threshold” level, the charger will return to normal mode without
activating any alarm.
The Battery Test Facility is optional. The default time of 5 minutes for this test can be
changed by front panel in the menu Battery Test Setup. ( Refer pg:24 )
5.4.2.1 PROCEDURE:
1) Press and hold ‘BATT TEST’ button for 5 seconds.
2) Display goes automatically to Capacity and Last ratio menu.
3) The display shows time left for this test and indicates the current drawn from
the battery.
4) The latest Impedance and Baseline Impedance values are also displayed
alternately.
Note: This test is done once in every 30 days by default from (1 to 99 days).
5.4.3 MODE 3: Battery Capacity Test
The Battery Capacity Test fully discharges the battery to record its available capacity
in ampere hours and will also display this value as a percentage of the expected
(rated value of the battery) value. The batteries are discharged down to their End
Voltage (called CAP TEST LEVEL on Battery test setup) into the discharge load
connected across them. It may take few hours depending on the Amp/hr of the
battery.
During this test the charger voltage is lowered to a safe level for the load connected.
The battery voltage and current are monitored by the CPU which constantly
calculates ampere hours discharged from the battery. This test continues until battery
voltage reaches ‘End Voltage’ as specified. After the ‘End Voltage’ is reached,
calculated Ah capacity with time taken will be displayed.
Special note: The test will be terminated if battery voltage falls below the End Voltage
at any moment during this test.

5.4.3.1 PROCEDURE:
1) Press and hold ‘BATT TEST’ button for more than 10 seconds.
2) Display goes automatically to Capacity and Last ratio menu, and alternately
shows Battery Impedance and Baseline mOhms, and then Capacity and
Battery Amps.
3) After the test is completed charger will start charging the battery.
4) Charge the battery bank.
Warning: Batteries should always be left in the charged state. Leaving
batteries in discharge stated will result in battery damage.
How to terminate the tests abruptly:
•Pressing the ‘RESET’ button any time during any of these three modes.
•Detection of ‘MAINS FAIL’ alarm will automatically terminate battery test
modes.
5.5 TEMPERATURE COMPENSATION
This facility adjusts the charger voltage in accordance with the battery temperature.
The charger voltage is lower at higher temperatures. For the Battery Temperature
Compensation to operate the temperature probes must be connected to the
terminals X5 provided on the charger. The temperature probes are to be mounted on
the battery terminals, ensuring good thermal contact.
If the battery temperature probes are not connected, then the battery temperature
indicated on the LCD panel would be very high. Incorrect connection, or
disconnection of the probes may result in the charger not operating, to avoid
overcharging an apparently hot battery.
5.5.1 Alarm Reset and Mute
5.5.1.1 Reset
Operating the Reset key on the front panel will reset any latched alarms, reset the
alarm mute and terminate a battery test (if active). All alarm functions (except for
Under and Over voltage trip) may be preset in either a latching or non-latching state.
When an alarm latch is set to the ON position (See User Programmable Set Point
Instructions), both the alarm LED and the common alarm will continue to indicate that
an alarm condition exists until the alarm has cleared and the Reset key on the front
panel is activated. When an alarms latch is set to the Off position, the alarm LED and
the common alarm will only indicate while the alarm condition exists.

Under voltage trip is always non-latching, as it also drives an auxiliary relay whose
function is to reconnect the battery as soon as the charging system returns to normal.
(This is an optional feature)
(See Alarm Operational Description).
Over Voltage trip is always latching.
5.5.1.2 Mute
The Mute key will silence the audible alarm while an alarm state exists.
The operation of the alarm mute has two pre-settable modes. (See User
Programmable Set Point Instructions).
In mode 1, the Mute key will continue to silence the audible alarm until a new alarm
condition occurs, or the Reset key on the front panel is activated.
In mode 2, the Mute key will continue to silence the audible alarm until it is reset by
the Reset key on the front panel. Therefore, any new alarm that occurs after the Mute
key has been activated will not operate the audible alarm.
5.5.1.3 Constant Current Charging
The MCR Series Rectifier has a built-in constant current charging function to enable
the user to perform commissioning charges when new batteries are installed, or
when cycling the existing battery bank.
To perform constant current charging, it is necessary to ensure no load is connected
to the charger (due to the high output voltage). The system has built in protection that
will terminate the constant current mode if any load current is detected.
Select the Constant Current Setting menu. (See User Adjustable Set Point
Instructions.) A warning screen will appear informing the user to ensure the load is
disconnected. Press the Mode key on the rectifier front panel to clear the warning.
Set the Constant Current Mode to ON by using the Arrow keys.
Pressing the Mode key will display the period which the charger will operate in
Constant Current Mode. Adjust by using the Arrow keys (if necessary.)
