Deep Sea Electronics DSE7320 Auto Mains Failure Control Module

DSE7320 MKII: The Gold Standard in Auto Mains Failure Control

The DSE7320 MKII is a powerful Auto Mains Failure control module designed to deliver high level capabilities for single genset applications. This module does not only start and stop your engine but it also monitors the incoming mains (utility) supply and switches automatically to the generator when the power goes out. The “MKII” designation means this is the newest evolution of the technology, with higher computing capability and a more robust set of inputs and outputs than its predecessor.

Key Features of DSE7320 Module:

It has a strong dual-core processor that makes processing quick and easy.

Easy to use because it has a large 4-line backlit LCD text display and a simple five-key menu.

Supports up to three remote display units, which makes it easier to keep an eye on things.

You may set up different power-up modes, timers, alarms, and inputs/outputs for personalized control.

The drag-and-drop powerful PLC editor makes programming easy without having to write complicated code.

Supports many languages and has a user-friendly interface design

Checks a wide range of engine data, such as speed, oil pressure, temperature, fuel use, and more

Full monitoring of mains (utility) with automatic start, switching, and stop features

Works with CAN engine protocols, even those that manage Tier 4 emissions.

It protects against reverse power, overload, and power monitoring (kWh, kVARh, kVAh).

Control of the fuel pump for manual priming

Configurable CT placement and protection against imbalanced loads to keep systems safe

The data logging feature keeps track of events and performance data for maintenance and diagnosis.

Specifications for electricity:

DC Supply Voltage: 8 V to 35 V all the time, and 5 V for up to a minute while cranking

Maximum operating current: 510 mA at 12 V and 240 mA at 24 V

Utility (Mains) Voltage Range: 15 V to 415 V AC (Phase to Neutral) and 26 V to 719 V AC (Phase to Phase)

3.5 Hz to 75 Hz is the frequency range.

The voltage range for the magnetic pickup is ±0.5 V to 70 V, and the frequency can go up to 10,000 Hz.

Size: 240 mm x 181 mm x 42 mm (9.4 x 6.8 x 1.6)

Size of the panel cutout: 220 mm x 160 mm (8.7 x 6.3)

Made to fit in control panels that are no thicker than 8 mm (0.3).

Application:

Automatically starting and switching between diesel and gas generating sets

Power backup systems that need to quickly and reliably find and respond to Mains failures

Managing backup electricity for homes, businesses, and industries

Monitoring and controlling the performance of the engine and genset for best operation

Working with systems for load shedding, reverse power protection, and power management

Advantages:

The dual-core processor makes sure that the generator is only offline for a short time, so it responds quickly.

Inputs and outputs that can be fully configured make it possible to adapt to different control methods.

Remote monitoring and communication tools make it easier to administer a system.

Built tough to last in industrial settings and keep working for a long time

The user interface is easy to understand, which makes setup, use, and troubleshooting easier.

Engineer’s Guide and Tips:

I’ve seen many DSE7320s outlive the engines they are controlling. The secret to their extended life in salt-air situations is the IP65 gasket. Always install the front panel gasket. Also, the RS485 port can be used for remote monitoring in the bridge or control room; you don’t have to go down to the engine room to check a fuel level or oil pressure reading.

Pro Tip: When setting up the module with the DSE Configuration Suite, always use a slightly longer ‘Low Oil Pressure’ delay for cold-start cycles in northern latitudes. This takes care of ‘nuisance trips’ of high viscosity oil before the engine gets up to temperature.
