REG216, REG216 Compact REC216 Numerical Control Unit

A number of different protection functions are provided in the

software permanently stored within the RE. 216 system. The

functions required to protect a specific plant can be individually

selected, activated and set. A particular protection function may

be used several times in different protection schemes. How the

signals are to be processed by the protection for the plant in

question such as the assignment of tripping, signalling and logic

signals to the various inputs and outputs is also determined by

appropriately configuring the software.

The system hardware is modular in structure. The number of

electronic devices and I/O units actually installed, for example, to

increase the number of protection functions or for purposes of

redundancy, can vary according to the requirements of the particular

plant.

Because of its modular design and the possibility of selecting

protection and other functions by configuring the software, the

generator protection REG 216 can be adapted for the protection

of small, medium and large generators as well as large motors,

power transformers and feeders, while the control unit REC 216

can perform data acquisition and control and supervision

functions in medium and high-voltage substations.

To cancel an action 

1. Briefly press ENTER . 

The positioner aborts the action in progress (e.g., Autoadjust).

Operation on the operating level 

On the operating level, the positioner works in the selected operating mode. There are four operating modes: 

• 1.0 CTRL_ADP (adaptive control) 

• 1.1 CRTL_FIX (fixed control) 

• 1.2 MANUAL (manual adjustment within the stroke range) 

• 1.3 MAN_SENS (manual operation within the sensor range) 

For details regarding switching between the modes, refer to the section titled "Functions on the operating level". 

When the 4 ... 20 mA signal is fed in, the positioner automatically starts up in the mode that was last active. Devices from the factory start up in operating mode 1.3. This also applies to devices that have been reset to the factory setting. 

In both manual modes, the valve can be adjusted manually by pressing up or down .

 The two automatic control modes are indicated by the control loop symbol in the display. For the manual modes the hand symbol is shown in the display.

Each RE. 216 protection system is engineered to fulfil the particular

requirements of the plant concerned. A specific set of

diagrams is provided for each installation, which defines the

system with respect to the electronic devices and I/O units installed,

their locations and the internal wiring.

The set of plant diagrams includes:

single-line diagram of the protection: complete representation

of the plant showing the c.t. and v.t. connections to the

protection.

standard cable connections: block diagram showing the

protection equipment cabling (electronic equipment racks to

I/O units).

protection cubicle layout: installation and locations of the

electronic equipment and I/O units.

electronic rack layout: equipment locations within a rack.

measurement circuits (three-phase plant diagram): connection

of the c.t's and v.t's to the protection.

auxiliary supply: external connection and internal distribution

of the auxiliary d.c. voltage supply.

I/O signals: external connection and internal wiring of the

tripping and signalling outputs and the external input signals.
