1.6 Control component
The control component is equipped with a fully automatic
monitoring and control mechanism, 2 separate
microprocessors for the start-stop process for parallel
and stand-by operation including lambda regulation and line protection/mains monitoring. You can find a
more detailed description in Chapter 2 (Control BMS
2007).
Software functions
start/stop and monitoring program
engine output regulation with start-up function for gentle engine loading/relief with adjustable ramp function
relief control
control function for fixed value/floating value control
lambda regulation including triggering a control valve
analog value processing of the following analog values for limits/switching values and control functions:
– oil pressure, cooling water temperature, exhaust gas temperature, busbar voltage, alternator voltage
– current (L1, L2, L 3), specified output, alternator output, lambda probe voltage
– engine speed, battery voltage
parametering triggering and release values and delay/release times
triggering the coupling relay for controlling the driving machine, auxiliary drives and alternator
synchronising
separate password-protected access levels for EVU, parametering and manual operation
controller for heating water return increasing mechanism including sensors (output signal 24 V~ / 0
–10
V )
module release and deselecting in heat operation with added optional modulation tool with external
Pt100 sensors in the overall heating water return to the block-type thermal power plant
Analog box for
battery voltage, Pt100, NiCrNi, mV, mA, speed, heating water return, lambda regulation, cooling water temperature
Alternator protection, line protection and synchronising
1. low alternator voltage 6. excess alternator temperature
2. excess alternator voltage 7. reverse power protection
3. low alternator frequency/speed 8. precision synchronising blocking relay
4. excess alternator frequency/speed 9. recording speed
5. excess alternator current/alternator short-circuit
Guard function, 3-phase for recording mains failure in parallel operation for
1. low/excess mains voltage
2. low/excess mains frequency
3. vector jump
triggering and release values and the triggering and return delay can be parametered
Potential-free contacts (transferred to terminal)
1. block-type thermal power plant available 5. auxiliary drive requirement with after-run time
2. alternator switch on (cogeneration module in operation) 6. group alarm
3. mains failure 7. service message
4. external mains switch on/off
