OPUS BATTERY DATA DISPLAY
The Opus Display shows State of Charge (SOC), baery
temperature, voltage and current. The display is used
primarily by the Operator to monitor SOC in between
charging breaks. (See below)
If the BMS detects a warning or alarm condion, it will
show the warning or alarm on the display. (See below)
For warnings, the buzzer will beep once per second.
Otherwise, the baery operates as normal. For alarm
condions, the buzzer beeps 3 mes per second for
15 seconds, to alert the operator that the baery will
shut o and forkli operaon will be disabled in 15
seconds.
Once the alarm condion is removed, the baery
can be restarted with the power/reset buon. When
troubleshoong a Li510 baery, be sure to note the
values displayed on the Opus screen before, during
and aer baery problems occur.
The following Warnings, Alarms and Alerts
may be displayed on the Opus during normal
operaon:
Low SOC Warning – typically the most common
warning, indicang that the baery needs to be
charged soon
Low SOC Alert – If the Baery reaches 0% SOC, the
baery will shut itself o in order to protect itself.
The buzzer beeps 3 mes per second for 15 seconds,
to alert the operator that the baery will shut o and
forkli operaon will be disabled in 15 seconds. If a
baery shuts o with a low SOC Alert, it can be reset
one me, aer which the forkli must immediately
return to the charging area so that the baery can be
charged
Low Voltage Alarm – If following a Low SOC Alert, the
baery is not immediately charged and connues to
be used, the baery will further protect itself with
a Low Voltage Alarm. Aer the Low Voltage Alarm
occurs, the baery cannot be reset and the forkli
must be towed back to the charging area
Low Voltage Warning – If the baery is at low SOC
and the forkli is performing work that puts a heavy
power load on the baery, a Low Voltage Warning
may occur. This is another indicaon that the baery
needs to be charged.
High or Low Temperature Warning – If the baery
gets within 5C of its high or low temperature limits, a
warning will be displayed on the Opus
High or Low Temperature Alarm – If the baery
exceeds its high or low temperature limits, an alarm
will be displayed on the Opus. The buzzer will beep
rapidly for 15 seconds, aer which the baery will
shut down for protecon.
The following Warnings, Alarms and Alerts
may be displayed on the Opus during error
condions:
Please Check CAN Communicaon – If this alarm
occurs during charging, it is typically indicave of
a communicaon error between the charger and
baery. This alarm is usually resolved by servicing
of the AUX pins on the charger connector on the
baery and / or the Aux pins on the charger’s
output connector. If this error occurs during forkli
operaon, with no charger present, it may
indicate a CAN communicaon error inside
