Control unit for emergency power peak load gensets KEA 101 SPL0 General The automatic control unit KEA 101 SPL0 is used in emergency power supply plants and peak load plants. The compact design comprises the synchronisation unit, load controller, mains failure recording and the complete generator protection. The additional relay units RZ 071-D and RZ 071-E are included in the delivery scope. The output relay functions 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 is operated by using the keys on the control panel. All the functions and the displays of the VDE 0108, including the drag indicator display, are provided. 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, 4 alarms with programmable actuation • Software for sprinkler operation • Integrated check synchroniser and synchronisation unit • Integrated load and cos φ controller • Sealable mains failure protection. The following can be monitored: Undervoltage and overvoltage, underfrequency and overfrequency, vector bounce voltage and frequency change dU/dt and df/dt • 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 by 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 Hardware • • • • • • • • • 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: • 2 analogue signal outputs 0 20 mA or 0 10 V • 3 analogue signal inputs, can be equipped for: Temp. Sensors PT 100 / PT1000, 0-10 V DC, 0-20 mA, NiCr-Ni Temperature and pressure sensor from MotoMeter, VDO, Noris PTC thermistor for generator protection* Measurement of battery charging current* • Modem* (analogue, ISDN, GSM) • Bus coupling units*, e.g. Probus • Hardware clock with battery back-up* Technical Data 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 27 relays, of which 22 are programmable, contact load: • 2 relays max. 35 V, 20 A DC, • 25 relays 250V AC, 6 Amp. Input for pick-up Battery monitor Four slots for analogue input-card modules Two slots for analogue output-card modules Two CAN bus interfaces • Device for panel mounting, Dimensions (WxHxD): 260x170x100 mm • Weight: approx. 2.2 kg, any installation position • Protection type (built-in): IP 44 • Ambient temperature: Storage -20°C ... +70°C Operation 0°C ... +55°C • Standards/regulations: VDE 100/710 • Switchable power supply: 9..12..15 V DC or 14..24..35 V DC * on request Alfred Kuhse GmbH An der Kleinbahn 39, 21423 Winsen Tel.: +49 (0)4171 / 798-0 Fax: +49 (0)4171 / 798-117 E-Mail: [email protected] http://www.kuhse.de Subject to modication Datenblatt_KEA101SPL0_de_uk02 Stand: 02/2007
