TOP-OFF MODE
When the GR-1 has finished its charging cycle and the result was
Battery Good it will go in to Top-Off Mode. In this charging mode
the battery is charged with a low current. The operator has the
possibility to end the Top-Off Mode by pressing the Stop key or the
GR-1 will stop itself when the Charging current drops below 2 A.
GR-1 alerts the user of this transition with a message and an audible tone.
During Top-Off Mode, the GR-1 sounds an audible alarm every minute, and keeps the user informed by
displaying the following information: Charging voltage, Charging current, Top-Off Mode message and the
amount of charge put back into the battery (shown in Ah).
Cycled messages inform the user that the battery is ready to be put back into service: Top-Off Mode / Good
Battery / Press Stop Key.
CHARGE COMPLETION
When Top-Off Mode is complete, the GR-1 will alert the user with
an audible alarm and will display the following information: Battery
voltage, available starting current in CCA, battery condition, and the
final amount of charge put back into the battery (in Ah).
Details can be found on the print-out.
The audible alarm will sound every 30 seconds, until the user presses the STOP button.
DIAGNOSTIC ACCEPTANCE CHARGE
During the Diagnostic Fast Charge mode the GR-1 can detect that the battery does not accept current as
expected. This means that the GR-1 switches over to the Diagnostic Acceptance Mode.
In this mode the battery will be monitored to see if it accepts a lower charging current then what normally is
used.
The Diagnostic Acceptance Charge mode will switch the charging current at fixed time intervals in an effort to
fully charge the battery.
When the GR-1 detects that the battery picks-up charging current it can switch over to the Diagnostic Fast
Charge mode again.
CHARGE COMPLETION
When Diagnostic Acceptance Charge is complete, the GR-1 will alert
the user with an audible alarm and will display the following information:
Battery voltage, available starting current in CCA, battery condition
and the final amount of charge put back into the battery (in Ah).
Details can be found on the print-out.
The audible alarm will sound every 30 seconds, until the user presses the STOP button.
2. MANUAL CHARGE (12 and 24 V)
The GR-1 prompts the user to select the battery type, standard and rating. In addition to that the charging
current and charging time needs to be entered as described in the Operating Steps (4 - 8).
The GR-1 charges the battery based on the voltage, current, and time that the user selects. It does not
continuously monitor the battery nor analyze the charging progress in an effort to optimize charging levels or
reduce charging time.
TIMED CHARGING (Between 5 and 120 minutes)
If a charging time is selected the GR-1 will analyze the battery briefly
display the measured voltage and available starting current in CCA
and then begin charging at the selected levels.
