OPERATING THE DIALOcharge:
Both the voltage and the current of the DIALOcharge are controlled simultaneously with a single knob, providing an infinite
selection between the MINimum and MAXimum range. This is acheived by an analogue triac-driven, phase shitfing duty cycle
control 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 described on page 6 : PREPARATIONS : CONNECTIONS
BEFORE MAKING ANY ELECTRICAL CONNECTIONS, ENSURE THAT THE 240Vac MAINS IS SWITCHED OFF !
•
Ensure the INPUT and OUTPUT circuit breakers are switched to the OFF position.
•
Rotate the POWER CONTROL knob anti-clockwise to the MIN position.
•
Connect the BLACK cable clamp to the battery NEGATIVE.
•
Connect the RED cable clamp to the battery POSITIVE.
•
Visually recheck that all the connections are safe and secure.
•
Switch the INPUT and OUTPUT circuit breakers to the ON position.
•
Note that the DualMeter will read zero. Press the Dual Meter Switch, the output voltage will be displayed. Release.
•
Slowly rotate the POWER CONTROL knob slowly clockwise until the needle of the DualMeter begins to move from zero.
(This indicates that the DIALOcharge output has matched the battery voltage.)
•
Continue to rotate the knob clokwise to increase the current.
CHARGING THE BATTERY:
During the charging process, it 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 quick start
•
solar systems. This reduces the GenSet runtime.
The DIALOcharge has the ability to meet the maximum charge rate of the 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% will only be accepted by the battery if the
charging current is at a low rate.
Fast charging is normally quite safe, but it could be detrimental to the life of an old battery if undertaken to frequently.
NORMAL CHARGING:
Normal charging provides a more acceptable and beneficial recharge process.
Manually control the charging current via the POWER CONTROL knob.
The higher the battery voltage and the lower the charging current, the more charged the battery is.
The lower the battery voltage and the higher the charging current, the less charged the battery is.
While the DIALOcharge will not allow the charging current to exceed its maximum by means of electronic current limiting , the
user must not allow the battery voltage to exceed the voltages as listed in the table b elow;
FLAT CHARGING:
Batteries in this condition have a very low specific gravity of the electrolyte and a very high internal resistance. This inhibits
the amount of charging current the battery will draw. The POWER CONTROL knob will need to be rotated clockwise closer to
MAX, effecting a higher setting than normal to obtain even a small amount of charge current. This is acceptable, but the result
is that the DIALOcharge will supply a higher voltage to the battery.
CARE MUST BE TAKEN AT THIS STAGE
As the DIALOcharge overcomes the high internal resistance of the battery, the charging current will begin to increase. The
charging current may even rise to the DIALOcharge’s maximum output. As the battery begins to accept charge, the voltage
will reduce to a more realistic value relevent to the state of charge of the battery. Once the battery is becoming more and
more charged the current will decrease and the voltage will b egin to climb. The user must not allow the battery voltage to
exceed the voltages as listed in the table above above.
