Alarm reset
Once the issue that tripped the system and triggers the alarm is eliminated, one can resume the
system to normal status by pressing the RESET key on the digital keypad (as shown in the figure)
to set the external terminal to "Anomaly reset command" and sending the command by turning on
the terminal or via communication. Before any anomaly alarm is resolved, make sure the operation
signal is at open circuit status (OFF) to avoid immediate machine running upon anomaly reset that
may case mechanical damage or personnel casualty.
