2. Overview of the controller
2.1 Overview
2.1.1 Operating the PPU 300
The PPU 300 controllers ensure that the system is protected for typical marine applications.
Only qualified people may install and commission the controllers. After the controllers are installed and commissioned, they are easy
to operate.
Push-buttons and LEDs
The operator can use the display unit push-buttons to operate the system. This includes changing modes, selecting actions to start
pre-programmed sequences, and silencing alarms. The push-buttons to start or stop the genset, or close or open the breaker(s), are
only active in LOCAL mode.
The operator can look at the display unit LEDs to see the operating status of the genset, breaker, and busbar.
Switchboard control
Each controller can be put under switchboard control. The operator then manually controls the genset speed and opens and closes
the breaker. Switchboard control is useful for troubleshooting. It can also be useful in extreme circumstances if the operator needs to
override the control system. Under switchboard control, all the controller functions are disabled. However, the controller protections
are still active. The controller monitors the operation, and if an alarm condition arises, the controller activates the alarm action.
Display unit screen*
The operator can monitor system operation on the display unit screen. The operator can also use the soft key buttons and the
display unit screen to log into the controller. The operator can then see the alarm lists and logs, and acknowledge and unlatch
alarms. The operator can also see and/or change the controller configuration.
PICUS*
PICUS - Power In Control Utility Software
PICUS is the PC programming and monitoring tool, available from DEIF free of charge. The operator can connect a computer with
PICUS to the controller by using a direct connection. The operator can log into the controller. The operator can then use PICUS to
monitor operation, send commands that correspond to the push-button actions, manage alarms, and see or change the controller
configuration.
INFO
See the PICUS manual for more information about how to monitor and change the controller configuration.
* Both the display unit and PICUS are controlled by user level permissions which grant or restrict access to features of the controller.
Some features or functions may not be accessible to an operator depending on the design of the controller permissions.
