MCU/CMCU

The GUARD LEVEL® MCU (Master Control Unit) is the core of a reliable monitoring and alarm system working in harmony with a number of Bergan products. The MCU guarantees ultimate performance and top-rated safety in tanks, vessels and in potentially hazardous work areas.

Master Control Unit (MCU)

This “go to” Intrinsically Safe and versatile unit supports up to three completely independent systems; HL (High Level), HHL (Overfill) and tank gauging. It’s also available in three physical sizes depending upon required number of I/O.

The HL and HHL’s well-designed mimic panels are comprised of bright amber and red LEDs for easy visibility, as well as a separate alarm acknowledge switch and differing frequency piezo buzzers with adjustable volume control.

The gauging section’s hardened and extended temperature-rated embedded computer with the powerful (Intel) i7 processor runs both Windows 10 operating software and CMS+ application software.

This CMS+ user interface is intuitive with a highly configurable 19-inch LCD touchscreen display that can also be console mounted.

The GUARD LEVEL® MCU can be connected to our Guard Power ® UPS redundant power source and, optionally, a Wi-Fi for remote slave display. Plus, the MCU provides multiple communication ports capable of Ethernet broadcast and Modbus communication over serial or Ethernet connections, meeting and exceeding your communication needs.

Uninterrupted Power Supply-400W (UPS-400)

Master Control Unit (MCU)

The GUARD POWER™ UPS-400 (Uninterrupted Power Supply- 400W) is a high-performance, quiet, fan-less unit specifically designed to work with the GUARD LEVEL® MCU (Master Control Unit) series of control panels that guarantees control of key emergency functions such as power failure alerts, push-button shut downs and battery operated backup alarms. It’s a crucial part of the Bergan family of monitoring and alarm systems.

The UPS-400’s ON/OFF push button serves as the MCU ON/OFF switch and provides for handshake and controlled shut down of the CMS+ software.

The MCU also provides for full galvanic isolation on MAIN and AUX input to output and has a power fail alarm with corresponding LED visual indicator. The panel also has an easily accessible power fail acknowledge switch.

The Dual Power fail output circuits for external alarm annunciation (Horn and Strobe) further ensure emergency readiness. This enables one circuit to stay on until power fail has been corrected significantly adding to system stability.

Additionally, the UPS-400 has battery backup options – a built-in sealed lead acid battery and an auxiliary input for external batteries for specified extended UPS running time – so power continues to flow.

when the unit is rebooted. Individual channels can be programmed for either an N.C. or N.O. sensor or steady or flashing output for the optional digital output function.

Alarm Monitoring Unit (AMU)

The GUARD LEVEL® AMU (Alarm Monitoring Unit) is an independently powered, main alarm control unit for detection of HL and overfill alarm sensors providing superior control with smart features including voltagefree relay for external signals, cable monitoring for each circuit, individual alarm blocking and a built-in power fail alarm. This versatile, compact device has 32 digital outputs and can monitor any 4-20mA/HART loop sensor (open and short circuit). The AMU comes with its own internal power supply for power fail annunciation with a LED and electronic sounder.

Just scroll through the channels on the keypad to conveniently adjust alarm delays or enable or disable the alarm blocking function. The LED shows a unique flash sequence notification if a channel is blocked.

All programmed settings are stored in non-volatile EEPROM memory, with exception being blocking code, so all channels are automatically enabled

Since the AMU utilizes high precision A/D conversion for all channel measurements, cable shorts and a cable break on individual channels are detected and alarmed. Individual LED indication and custom nameplate is provided for each channel.

All measured data as well as remote acknowledgment is handled from the MCU and associated CMS+ software with the built-in RS422 communication port.

With the digital output option, the AMU can be supplied without a front panel. In this case, all alarm indications are on the discreet LEDs on the MCU – or in a customer provided console.

The GUARD LEVEL® DAC+ (Deck Alarm Cabinet+) is a durable solarpowered monitor and alarm panel that forms the building block for our SMARTBARGE® integration and other inventory control systems.

Deck Alarm Cabinet+ (DAC+)

The GUARD LEVEL DAC+’s rugged design is ideal for open deck mounting onboard river and coastal tank barges.

With Independent high and overfill (HH) level alarms for up to 12 tanks, the GUARD LEVEL® DAC+ is also a match for land-based tank batteries or other remote locations when power is not easily accessible.

Add a PLC (programmable logic controller) capability and the DAC+ becomes a data collection central unit for any 4-20mA/HART type of sensor signals including level, temperature, pressure, and oxygen levels. In addition, the PLC option can communicate with a remote explosion-proof display, like our GUARD LEVEL® MTDE (Multifunction Tank Display, Ex ).

Set up a wireless modem to transmit data and collect associated alarms together with time stamp, GPS location and system status. Status readings include battery percentage, solar panel voltage and solar charge for all power sources plus the DAC+ total system draw A.

Wireless transmission can be conveniently set for fixed intervals, event or GPS driven.

The GUARD LEVEL® Simple Deck Alarm Cabinet (SDAC) is a solar-powered, low-cost HL and HHL (Overfill) level alarm panel. It is ideal for open deck mounting onboard coastal and river barges, and other shore facilities.

The SDAC is cleverly built to detect a series of connected alarm sensors sounding a common HL and HHL audible and visual local alarm with two Independent Alarm Control Units.

External alarms include red and amber strobe lighting, an electronic sounder with distinct tones and a blue LED power fail low voltage indicator. A built-in power fail alarm function and a low power level warning are included. The panel also comes with Intrinsically Safe shore alarm connection relays (voltage free) for API shore connect receptacles.

The built-in solar panel charges a primary and secondary power source either of which can be used as the power fail source.

With its solid-state design, built-in Intrinsically Safe barrier circuits and the automatic by-pass switch, the SDAC assures safe loading under all conditions.

GUARD POWER™ RDU-Series

RUGGED REMOTE DISPLAY FOR GENERIC 4-20MA AND CARGORADAR® SENSORS (UP TO 25M / 82FT AWAY)

Remote Display Unit (RDU)

The GUARD LEVEL® RDU (Remote Display Unit) is a series of rugged remote display instruments made in two distinct models – RDU-81 and RDU-82 – with different connection options.

The RDU-81 is specifically designed for the CARGORADAR® units and uses a 4-wire connection.

The RDU-82 is similar to the RDU-81 except it is designed as a universal display for any 4-20mA/HART type 2-wire sensor making it ideal for remote display for the HPT series of pressure sensors.

Each display can be mounted up to 82 feet (25 meters) away from the radar sensor and contains a full graphic LCD display for level, volume pressure or temperature with a light for nighttime viewing and imperial or metric options.

Both displays have a rugged cast stainless steel 316L housing with a viewing window and is suitable for classified “Safe” and, when requested, “Hazardous” area usage.
