The SICES DST4602-DST4602Evolution SPtM+SSB is an installation guide for a device designed for single parallel to mains and single stand-by operations. This device is an advanced control system for power plants, offering comprehensive management of generators, mains, and load.

Function Description

The device's core function is to manage the operating modes of a power plant, including PROGRAM-OFF/RESET, MANUAL, AUTOMATIC-TEST, and AUTO. It provides a user-friendly interface for visualizing configuration parameters, plant status, electrical measurements, engine analogue and digital measurements, digital IN/OUT signals, and historical events and measures.

Navigation and Display: The device features a multifunction display and navigation buttons (UP, DOWN, LEFT, RIGHT, ENTER, ACK, EXIT, SHIFT).

UP and DOWN buttons: Used for vertical navigation through menus and configuration parameters.
LEFT and RIGHT buttons: Used to move through pages within the same menu.
ENTER button: Provides access to submenus, enables value adjustment, and confirms changes.
ACK button: Silences the horn and acknowledges warnings/alarms.
EXIT button: Returns to the previous menu or cancels an adjustment.
SHIFT button: Increases value movement by up to x10 or adjusts display light.
SHIFT + LEFT/RIGHT: Decreases/increases display contrast.

Operating Modes: The device offers several operating modes, selectable via buttons or a key switch.

PROGRAM – OFF/RESET (Engine Stopped): In this mode, all control and switching commands are disabled, and no faults are revealed. Users can view programming pages and access the configuration menu to adjust parameters (some may require a password).
MAN. (Engine Started/Stopped): This mode enables control commands. The engine can be started and stopped using the START and STOP buttons. When the genset is running and electrical measurements are within tolerance, the GCB (Generator Circuit Breaker) button can be used to open/close the GCB circuit breaker/changeover switch, with possible synchronization based on plant configuration and status.
- When the mains is powering the load, pressing the GCB button activates a fast unload ramp before the circuit breaker opens. If no ramp is needed, holding the GCB button for a few seconds will open the circuit breaker.
- The MCB (Mains Circuit Breaker) button controls the opening and/or closing of the Mains contactor/circuit breaker to the Load. With the engine off, holding the MCB button for at least 5 seconds will open the Mains MCB circuit breaker.
AUTO (Engine Started/Stopped automatically): In this mode, the device automatically starts the genset (START), manages GCB closing, and checks electrical measurements based on operating conditions.
- The STOP button, if configured, will stop the generator and activate a lockout.
- If genset operation is no longer required, the device performs power discharge, opens the GCB, and cools the engine for a set time before stopping the engine.

Usage Features

Parameter Configuration: The device allows extensive parameter configuration, accessible through the PROGRAMMING menu.

Password Protection: Access to programming mode can be protected by 3 or 4 password levels (SICES, Maker, System, User), depending on the device. Higher-level passwords can reconfigure lost lower-level passwords.
Parameter Adjustment: To adjust parameters, navigate to the PROGRAMMING page, select submenus with UP/DOWN, and press ENTER. Use UP/DOWN to change values and ENTER to confirm, or EXIT to cancel. Parameters indicated by square brackets [..] can be adjusted, while those with < > cannot (due to password authorizations or operating mode restrictions).
Language Selection: The language can be changed via the S.03 (BOARD STATUS) screen. Press ENTER, use UP/DOWN to select the language, and ENTER to confirm.

Protections and Alarms: The device incorporates adjustable protections and alarms.

Adjustable Variables: Protections and alarms are typically adjustable via specific variables, including intervention time.
Deactivation: Setting the acquisition time to 0 (zero) deactivates the protection.

Maintenance Features

While the manual primarily focuses on installation and operation, certain aspects contribute to maintenance:

Event and Measure History: The device records historical events and measures, which are crucial for diagnostics and troubleshooting. This data helps identify patterns, pinpoint issues, and inform maintenance decisions.

Password Hierarchy: The multi-level password system ensures that critical parameters are protected from unauthorized changes, which is vital for maintaining system integrity and preventing accidental misconfigurations that could lead to malfunctions or damage. The ability to reconfigure lost passwords using a higher-level password simplifies recovery in case of administrative oversight.

Configuration Backup: Although not explicitly stated as a "backup" feature, the detailed parameter configuration section implies that settings can be systematically recorded and potentially restored. This is essential for consistent operation across multiple devices or after system resets.

Error Handling and Alarms: The device's ability to reveal faults (warnings/alarms) and allow acknowledgment via the ACK button is a key maintenance feature. It alerts operators to potential issues, enabling timely intervention and preventing minor problems from escalating into major failures.

Software and Hardware Configuration: The manual notes that plant sequences depend on the software and hardware configuration during installation. This highlights the importance of proper initial setup and implies that future maintenance or upgrades might involve re-evaluating these configurations. The availability of technical documentation in the "Download Area" on the SICES website further supports maintenance by providing resources for understanding and troubleshooting the device.
