SYMAP® ECO, Genset Controller & Protection

SYMAP^® ECO is a digital single-genset control and protection device built on the SYMAP^® hardware platform, with a large graphic LC display and function keys. It is easy to operate and program.

Protection and control functions (ANSI)

ANSI 15, Matching device
ANSI 25/A, Automatic synchronising (check-sync)
ANSI 27 / 27B, Undervoltage (generator / bus)
ANSI 32, Overload
ANSI 46/RP, Reverse phase / rotor protection

ANSI 50 / 51, Overcurrent (instantaneous / time)
ANSI 59 / 59B, Overvoltage (generator / bus)
ANSI 81, Frequency protection
ANSI 94, Auxiliary voltage supervision
Reverse power; prealarm/shutdown levels (U/f/P)

Genset control

Genset start-stop sequence; AUTO and MANUAL operating modes
Direct communication with the engine control unit (ECU) over CAN-Bus
Supported protocols: DEUTZ, VOLVO, SCANIA, J1939; MTU via CANBUS 2
Single-line display (busbar and breakers) on screen

Source transfer and synchronisation

Automatic mains failure (AMF): control of mains and generator breakers
overlap return to mains by back-synchronisation, with no power interruption (no-break)
over gap return to mains with a small interruption (open transition)
Supervision: alarm on back-synchronisation failure

Parallel operation with the mains is only momentary, during transfer; not for continuous grid-parallel operation.

Measurement and I/O

3 × CT (generator current), 3 × PT (generator voltage), 3 × PT (bus voltage)
Energy and power metering; harmonics up to the 5th
Binary inputs (24 V DC) and binary outputs (including a "Sync ON" output)
Digital and analog outputs to switchboard controls

Communication

RS232 (front panel), programming and data output
RS485 MODBUS RTU to the supervisory/central system
CAN-Bus interface to the engine control unit (ECU)

The device provides no remote access; PC access is password-protected with operational timeout.

Recording and supervision

Recording unit: event history, detailed protection history, start/stop history
Permanent data store (independent of power supply)
Binary input supervision: wire break and short circuit; additional limits

Standards (type tests)

EMC: EN 61000-6-2 (immunity), EN 61000-6-4 (emission)
Vibration: IEC 60068-2-6
Measuring relays: IEC 60255
Degree of protection: IEC 60529
