The is a high-performance, microprocessor-based integrated protection and control device designed for low and medium voltage switchgear applications. Part of the SYMAP family, the CMA 216 (Compact Monitoring and Protection) variant is specifically optimized for marine vessels and industrial power plants where space is limited but comprehensive electrical protection is mandatory.
Product Overview
The CMA 216 serves as a multi-functional unit that combines protection, control, measurement, and communication into a single hardware platform. It is engineered to monitor generators, motors, and transformers, providing real-time data acquisition and autonomous fault management. Its robust design meets the stringent vibration and environmental requirements of major marine classification societies.
Technical Specifications (Datasheet)
Key Technical Features
- Integrated Protection Functions: Includes overcurrent (ANSI 50/51), over/undervoltage (27/59), frequency protection (81), and directional power protection (32).
- High-Resolution Measurement: Provides True RMS values for voltage, current, active/reactive power, power factor, and harmonic analysis up to the 15th harmonic.
- Programmable Logic: Features a built-in PLC-like logic editor (LogiSoft) for creating custom interlocking sequences and automated load shedding schemes.
- Event & Fault Recording: Maintains a non-volatile “Black Box” log that records the last 100 events and provides oscillographic fault records for post-incident analysis.
- HMI Interface: Equipped with a high-contrast backlit LCD and tactile membrane keys for local parameter adjustment and status monitoring.

Primary Application Fields
The SYMAP CMA 216 is a preferred solution for:
- Main Marine Switchboards: Protection and control of shipboard diesel-generator sets.
- Emergency Power Systems: Managing automatic mains failure (AMF) transitions.
- Industrial Substations: Feeder protection and transformer monitoring in manufacturing plants.
- Offshore Platforms: Providing reliable electrical safety in corrosive environments.
Operating Instructions
- Mounting: Install the device in a panel cutout. Ensure the rubber gasket is correctly seated to maintain the IP54 front-panel rating.
- Wiring: Connect the CT and PT secondaries to the appropriate terminals. Caution: Ensure the current transformer circuits are never opened while the primary is live.
- Parameterization: Use the SYMAP-Win software via the serial port or the front-panel menu to set the protection curves (Inverse Time, Definite Time, etc.) and nominal system values.
- Testing: Utilize the integrated test mode to simulate fault conditions and verify that the output relays actuate the intended circuit breaker trip coils.
- Synchronization: If used for generator control, verify the phase rotation and voltage matching settings before enabling the automatic synchronization feature.
