Control unit for emergency gensets KEA 101 NSTR General The automatic control unit KEA 101 NSTR is used in emergency power supply plants without overlapping synchronisation. Complete generator protection is included. The additional relay unit RZ 071-D of the KEA 070 series is included in the delivery. The output relay function and the parameters can be set with a PC. As the KEA 101 is the same size and is attached in the same manner as its predecessors, it can be exchanged without difculty. The automatic control unit is simple to operate as it is operated by using the keys on the control panel. Functions • Start-stop for Diesel and gas engine with checking of preliminary start-up conditions • Sensors for mains and generator voltage, frequency and rotating eld (asymmetry) • Generator current sensor: Overload, short-circuit, unbalanced load and thermal overload (bimetal relay) • 48 alarm signals, of which 19 alarms with programmable text and actuation, 7 alarms (alarms 24-26 and 33-36) with programmable actuation • Software for sprinkler operation • For each analogue signal input, actuation of two alarms via limits • Two potential-free analogue signal outputs, e.g. for direct actuation of speed controllers or other controllers • Parameters can be set using the keys and the display or via a bre optics or USB interface with the ParaWin software • Data transfer to a central control system via a CAN bus interface • CAN bus interface* to engine management • Various enhancement options: Modem, printer actuation, Probus coupling etc. Hardware • • • • • • • • • Input for alternator D+ with pre-excitation for AC alternators 14 terminals for alarm contacts on the RZ 071-D 14 general control inputs on the RZ 071-D 12 relays on the RZ 071-D, 8 of which can be parameterised, contact load: 2 relays max. 35 V, 20 A DC 10 relays 250 V AC, 6 A Input for pick-up Battery monitor Four slots for analogue input-card modules Two slots for analogue output-card modules Two CAN bus interfaces Optional functions The hardware must be upgraded accordingly for the software options listed below: • Integration of the automatic control unit in telephone monitoring by means of an internal modem (analogue, ISDN, GSM) • Connection to other systems via Probus, for example • Event recorder with protocol and fault printout via an RS 232 interface Hardware options Free analogue signal inputs and outputs can be used as follows: • Relay extension unit RZ 071-E: 15 relays on the RZ 071-E, 14 of which can be parameterised, contact load 250V AC, 6 A • 2 analogue signal outputs 0 20 mA or 0 10 V • 4 analogue signal inputs, can be equipped for: Temp.
