The battery charger LCD display will indicate
"FLT" as well as the battery voltage and the
delivered current.
Charger Failure Alarm
A single Form C relay output will activate if the
charger fails during a charge cycle due to any of
the following conditions:
Maximum battery charger output voltage has been
exceeded.
1
Battery charger output voltage is greater than the
maximum battery voltage threshold.
1
Battery charger output voltage is less than the
minimum battery voltage threshold.
1
Battery charger output voltage is greater than the
battery charge mode maximum voltage threshold.
2
Battery charger output voltage is less than the
battery charge mode minimum voltage threshold.
2
Loss of AC power.
The Charger Failure Alarm relay is normally
energized and utilizes the Normally Open contact
to signal the alarm condition. When there is a
failure, the relay de-energizes.
Dead Cell Alarm
A single Form C relay output will activate if the
battery fails during a charge cycle due to any of the
following conditions:
Battery charger output current is greater than the
maximum battery current threshold.
1
Battery charger output current is greater than the
battery charge mode maximum current threshold.
2
Battery charger output current is less than the
battery charge mode minimum current threshold.
2
Loss of AC power.
The Dead Cell Alarm relay is normally energized
and utilizes the Normally Open contact to signal
the alarm condition. When there is a failure, the
relay de-energizes.
Note: The Dead Cell Alarm relay is not provided
and must be ordered separately.
Charger Shut Down
The charger will automatically shut down if there
is no load connected to the output or if there is a
short on the load side of the charger. In addition,
the charger will not operate if a battery is
connected incorrectly or if the wrong voltage of
battery is connected.
AC Input Fuse Protection
The AC Supply is protected by a 5 amp fuse which
will blow in case of a breakdown of the charger.
This fuse will not blow as a result of overloading of
the charger since the electronics will shutdown the
charger in this event before the fuse blows.
LCD Display
A 1 line by 16 character LCD display on the front
of each charger will alternately show:
Charging Amps; Voltage; Alarms
As well, error messages will be displayed
according to the conditions that exist.
“NO BATTERY”
is displayed if no battery is
attached to the charger.
“BATTERY ERROR”
is displayed if a battery is
connected to the charger but the voltage is not
within the minimum and maximum thresholds for
the selected battery type.
“ERROR, RECOVERING”
is displayed if the
maximum battery charger output voltage (31.4V)
has been exceeded.
“VOLTAGE ERROR”
is displayed if a charging
test fails during a charge cycle due to any of the
following conditions:
Battery charger output voltage is greater than the
maximum battery voltage threshold.
1
Battery charger output voltage is less than the
minimum battery voltage threshold.
1
Battery charger output voltage is greater than the
battery charge mode maximum voltage threshold.
2
Battery charger output voltage is less than the
battery charge mode minimum voltage threshold.
2
“TEMPERATURE ERROR”
is displayed if a
temperature error is detected.
Temperature errors:
Internal temperature is greater than the maximum
ambient temperature.
External temperature is greater than the maximum
battery temperature. If the external temperature
probe is not connected (terminal P2) the internal
temperature is used in its place.
Note: The ambient and battery maximum
temperature threshold are both 60°C.
