Operations - Woods Dialocharge D1230 User Manual

OPERATIONS:

OPERATING THE DIALOcharge:
Both the voltage and the current of the DIALOc harge are controlled s imultaneous ly with a single knob, providing an infinite
s elec tion between the MINimum and MAXimum range. This is acheived by an analogue t riac-driven, phase shitfing duty cycle
c ontrol of the MAINS ac input to the transformer. The OUTPUT dc voltage and current are battery and/or load dependant.
CONNECTING THE BATTERY:
Fit the INPUT and OUTPUT cables as desc ribed on page 6 : PREPARATIONS : CONNECTIONS
B EFORE MAKING ANY EL ECTRICAL CONNECTIONS, ENSURE THAT THE 240Vac MAINS IS SWITCHED OFF !
•
Ensure the INPUT and OUTPUT c ircuit breakers are switched to the OFF position.
•
Rotate the POWER CONTROL knob anti-cloc kwise to the MIN position.
•
Connect th e BLACK cable clamp t o t he battery NEGATIVE.
•
Connect th e RED cable clamp to the batt ery POSITIVE.
•
Vis ually recheck that al l the c onnec tions are safe and secure.
•
Switch the INPUT and OUTPUT c ircu it breakers to the ON position .
•
Note t hat t he Du alMeter will read zero. Pres s the Dual Meter Switch, the output voltage will be dis played. Rel ease.
•
Slowly rotate the POWER CONTROL knob sl owly clockwise until the needle of th e DualMeter begins t o move from zero.
(This indicates that the DIALOc harge output has matc hed t he battery voltage.)
•
Continue to rotate t he knob clokwise to increase the current.
CHARGING THE BATTERY:
D uring the charging process , i t is important to frequently visually test and read the battery voltage via the DualMeter.
FAST CHARGING:
Fast charging is most useful for boost charging batteries on;
•
vehicles that require a quic k st art
•
solar systems. This reduces the GenSet runt ime.
The DIALOcharge has the abilit y to meet the maximum c harge rate of t he battery, according to its condition.
A battery in good condition will accept a much higher rate of charge more readily than an old, sulphated battery.
Batteries can be charged to 80% of full charge by fast charging. The remaining 20% wi ll only be acc epted by the battery if the
c harging current is at a low rate.
Fast charging is normally quite safe, but it could be det rimental to the life of an old battery if undertaken to frequently.
NORMAL CHARGING:
Normal c harging provides a more acceptable and benefic ial recharge proces s.
Manually control the c harging current via the POWER CONTROL knob.
The higher t he battery voltage and the lower the charging current, the more c harged the bat tery is.
The lower the battery voltage and the higher the charging current, the less charged the battery is.
While th e DIALOcharge will not all ow the chargin g c urrent t o exceed its maximum by means of electronic current limiting , the
us er must not allow the battery voltage to exceed the voltages as listed in the table b elow;

FLAT CHARGING:
Batteries in th is condition have a very low specific gravity of the elec trolyte and a very high int ernal resis tance. This inhibits
t he amount of charging current the battery will draw. The POWE R CONTROL knob will need t o be rotat ed clockwis e clos er to
MAX, effect ing a higher setting than normal to obtain even a small amount of c harge current. This is acceptable, but the result
is that the DIALOc harge will supply a higher voltage t o t he battery.
As the DIALOcharge overcomes the high internal resistance of the bat tery, the c harging current will begin to increas e. The
c harging current may even ris e to the DIALOcharge' s maximum output. As th e battery begins t o acc ept c harge, t he voltage
will reduce to a more realis tic value relevent t o the state of charge of the batt ery. Once the bat tery is becoming more and
more ch arged the c urrent will decrease and the voltage will b egin t o c limb. The user mus t not allow the battery voltage t o
exceed the volt ages as lis ted in the t able above above.
