GNB EHF Series Product information sheet

Operating Instructions and Safety Precautions for the EHF Series Charger
Safety
Only a t rained person should operate this equipment. The input
and output voltages used with this equipment may be high enough
to endanger life, so insulated, shrouded connectors must be fitted.
Please read this manual completely and convey instructions to all
personnel concerned. Keep the manual in a safe and convenient
place.
It is advisable to thoroughly read the information on battery safety
supplied with the battery, prior to charging.
Towards the end of charge, lead acid batteries give off hydrogen
gas, which is explosive if in sufficient concentration, therefore
avoid flames and sparks. Appropriate measures must be t aken to
ensure adequate ventilation.
Incorrect use of a charger or maladjustment of its controls can
damage a battery. The equipment has been f actory set and does
not require user adjustment.
This product has been designed, manufactured and certified to be
in conformance with UL Standards. Testing has ensured that the
battery and c harger combination conform as a system for use in
Light and Heavy Industrial environments for each respective
product variant. The following notes are for the guidance of the
person installing and using the product.
The charger must be i solated from the input supply and t he
battery, before any of the panels are removed. It is strongly
recommended that a Safety Warning Notice is placed at the input
supply isolator, to warn against inadvertent reconnection of the
mains supply and the isolator is locked in the off position.
DANGER - Risk of electric shock. Do not touch un-insulated
portion of output connector or un-insulated battery terminal.
Installation
Installation must only be carried out by suitably qualified personnel
and in accordance with current local and national wiring
regulations.
The unit should be positioned using lifting equipment, placed under
the base.
Battery leads should not be al tered without prior consultation with
service personnel.
The charger should be sited in a cool, dry, well-ventilated location
away from corrosive fumes and humid atmospheres. Ambient
temperature range must be maintained between 32°F - 95°F.
The charger must have a minimum clearance overhead of eight
inches (8”), ensuring ventilation is not obstructed at the rear intake
and the front exhaust vents.
The charger is for inside use only.
Before installation, check that:
• The charger has not sustained any transit damage.
• The rating is suitable for the intended input supply and ‘lead
acid’ battery to be charged.
• The connector polarity is correct and matches the polarity of
the battery connector.
Input supply
A hand operated lockable isolator should be used in the
installation, to enable the charger to be disconnected from the
supply, for maintenance or repair work. The charger does not
exhibit high in-rush current, therefore type B or C circuit breakers
can be used.
CAUTION - To reduce the risk of fire, use only on circuits provided
with branch circuit protection consistent with the current indicated
on the rating label and i n accordance with the National Electrical
Code, ANSI/NFPA 70 or equivalent.
The circuit breakers rating should be bas ed on the chargers
maximum input current, as stated on the rating label.
Careful consideration must be taken when connecting this charger
to a generator. The generator must be capable of at least four
times the input power requirements of the charger, failure to do so
can result in damage to the charger. The generator should have
load step immunity to prevent undershoot and overshoot with
typical loads. Typically the generator control bandwidth should be
less than 7Hz with good gain and phase margins.

Operation
Before connecting the battery, check that the battery voltage
corresponds to the voltage indicated inside the battery
symbol on the LCD Display. The charger should be
permanently connected to the mains supply.
Standby
With the input supply connected and no battery, the charger will
enter the standby mode. During this mode the charge status
indicator will show indication 6 and the LCD display will show the
following:

As a power saving feature the LCD backlight will be switched off
after 1 minute of inactivity, the backlight can be turned back on by
briefly pressing any of the buttons. During this time the charge
status indicator will show indication 7.
Charging
When a battery is connected to the charger, charge will start
automatically. The charge status indicator will show indication 1 or
indication 2 (The speed of the rotation indicates the state of charge
of the battery, with fast cycling indicating a low charge state) and
the LCD Display will show the following:
The bar graph display gives the user an indication of the batteries
present state of charge.
During charge, the user can scroll through the following charge
information, by pressing the or keys.
• VPC Voltage per cell
• Ah Total Ampere hours delivered to the battery
• Amps The present output current
• Stage The present charge stage
• Charge Time The total charge time
• Rest Time Time elapsed since charge completed
• Warnings Displays any warnings - Only shown when
applicable
Charge Complete
When charge is complete the charge status indicator will show
indication 3 and the LCD Display will show the following:
If the Auto Balance feature is enabled the battery should be left
connected to the charger until required; under these conditions the
battery will receive periods of refreshing charge to maintain it in the
fully charged condition. During these periods, the charge status
indicator will show indication 4.
Removing the battery
The battery can only be disconnected when charging current
has stopped flowing. Therefore, the pause button must be
pressed before disconnection. A second press of the pause key
will clear the pause condition and continue charge (Disabled
during the first 10 seconds of pause).
When the charger is paused the charge status indicator will show
indication 6 and the LCD Display will show the following:
If the pause mode is entered but the battery is not removed within
10 minutes the charge will automatically continue.
Equalize Mode (Profile Dependant)
Periodically, batteries require additional charging to equalize all of
the cells to the same charge state, this should be performed after
the standard charge has completed.
This mode can be enabled by pressing the = key during the charge
cycle, a second press will clear this function. The equalize function
can not be c leared once it has started and onl y one equalize is
allowed per cycle.
In addition to enabling equalize manually, the equalize feature can
be set to initiate automatically by configuring the automatic
equalize feature in the programming mode. Automatic equalize
may be set to occur every 0 to 250 cycles. Once set the A=
symbol will be shown in the top right corner of the LCD Display.
Once enabled, the charger will perform the equalize function after
the standard charge has been completed.
Battery Recover Mode
If a bat tery is connected to the charger that is below the normal
operating voltage an incorrect battery fault (F07) will be displayed.
However if the battery voltage is between 1 and 1. 5VPC, battery
recover mode is available. This mode employs a special charging
technique to recover batteries that have been left unused for a
long time or have been over discharged.
This mode can be enabl ed by pressing the BRM key when the
fault is displayed. Battery recover mode will then start; once the
battery voltage has been r ecovered to a normal level a standard
charge will be performed.
Cool Down Mode (Profile Dependant)
Cool down mode is activated after the charge has completed and
allows the battery time to ‘cool down’ before its next use. During
this time the battery should remain connected to the charger, but
can be removed if required.
Delayed Start
Note: This function is only available if the network function is OFF
and can only be set without a battery connected.
The delayed start function will delay the start of charge for a s et
time up to 48 hour s in 15 minute increments. The timer begins
count down upon connection to a battery.
During the delay period the charge status indicator will show
indication 6 and the LCD Display will show the following:
Once the time period has elapsed, charge will start as normal. This
can be overridden by pressing the >> button, for this cycle only.
