The settings section has several options. Some icons, such as "Start Disabled", will toggle the function selected. Other icons will navigate to a submenu. The icons on the display may vary from those icons seen in Illustration 2 due to another mode that is selected.

Mode (5)

Depending on the configuration of the DCU, some of the following modes will be available.

Locked to Input - As shipped from the factory, the MGCP II is programmed to control the DCU mode using the ECS. The mode cannot be changed from the menu. If the panel configuration has been changed, the options below may be available.

Local - Only local operation is allowed.

Manual or Remote - Remote operation is allowed. Local operation is allowed only if enabled in the configuration.

Automatic - Automatic and remote operation is allowed. Local operation is allowed if enabled in the configuration.

Emergency - All overridable shutdowns will become alarms. Overspeed is never overridable. Other shutdowns, such as "Oil Pressure", may be configured as non-overridable. Local, remote, and automatic operations are allowed.

Harbor - Shutdowns are not overridden. Remote operation is allowed. Local operation is allowed if enabled in the configuration.

Modes and Engine Applications

The engine application set in the configuration determines the modes that will be available. Refer to Table 1.

Update PAM to DCU

The power analyzer module (PAM) and shutdown unit (SDU) 410 or 404 configurations can be updated from the DCU. If the DCU has been replaced, the user may desire to keep the settings on the PAM or SDU and update the DCU instead.

Network Configuration (28)

Illustration 11	g06067978
(38) Must match remote panel (RP) settings (39) Must be unique for each DCU

The network connection is used to communicate to system such as remote panels (RP), computers, and SCADA systems outside the control panel. Each DCU on the network must have a unique IP address. The last two numbers of the IP address are used by the remote panel to indicate the engine number. The factory default address is 192.168.0.101. The first three numbers must match the numbers of the remote panels on the network to ensure proper communication. Select a number under "Change IP" to change the IP. Select "OK" to update the address.
