2.3.2 Control Function of the Operation Panel
The operation panel has the following switches to implement its control function:
  1. Mode switch (slide switch)
    Specifies the mode for either operation or maintenance.
  2. Power switch
    Controls start/stop of the system.

The mode switch sets the operation mode for the system. The Locked and Service operation modes can be switched by sliding the mode switch.
Table 2-3 describes the difference between the modes.
Table 2-3  Functions of the Mode Switch
Icon Name Description
locked_mode Locked mode Mode used for normal operation
- The power switch can be used to start the system but not to stop it.
service_mode Service mode Mode used for maintenance
- The power switch cannot be used to start the system but can be used to stop it.

- Place the system in Service mode to perform maintenance work with the system stopped.
Use the power switch to start or stop the system. The system starts/stops differently depending on how the power switch is pressed.
Table 2-4 describes how system starts/stops vary depending on how the power switch is pressed.
