  • Page 41: Figure 13 - Assisted Manual Mode Without Main Paralleling

    Depending on its setup (island mode, paralleled with Mains or other generating sets…), GENSYS 2.0 will automatically use the appropriate process: synchronization (if bus bar is live), closing the generating set’s breaker, loading ramp (if bus bar is live). Then it will manage the load depending on the setup (load sharing, fixed kW setpoint…).

  • Page 43: Automatic Mode

    This mode allows testing automatic mode behaviour. When [TEST] key is pressed, the engine starts as if there was a remote start, and GENSYS 2.0 will carry out the standard Auto mode sequence. To exit “TEST MODE”, push [AUTO] or [MAN] key.

  • Page 44: Semi-Automatic Mode

    START button will automatically start the engine. The whole standard starting sequence is performed, and then the engine is let running at nominal speed without any other action from GENSYS 2.0. STOP button will stop the engine without performing any cool down sequence.

  • Page 45: Manual Mode

    The MANUAL mode replaces the ASSISTED MANUAL mode that is not available anymore. In MANUAL mode, it is possible to control the generator with the front panel of the GENSYS 2.0. All steps from engine start to paralleling are controlled by pushing keys.

  • Page 46: Start Sequence

    7 Start sequence During the start sequence protections are inhibited. This concerns all engine protections. When the engine reaches genset ready, the protections are activated. A timer can be added to inhibit protections during the "safety on" delay [E1514]. The timer will start when the genset is ready. Stop E1080 (Nominal Speed ) E1079 (Idle Speed )
  • Page 47 Analogue sensors: The analogue oil pressure and water temperature sensors are used before start-up for the preheat and pre- lube checks: the water temperature [E0030]and oil pressure [E0029] must be ABOVE their respective thresholds (E1155 & E1154) for the engine to be allowed to start. The default setting for these thresholds is zero.

    Table 12 - Typical basic configuration for GENSYS 2.0 with parallel line modules When GENSYS 2.0 is in analog load sharing mode, the active power sharing is handled via the parallel lines. You have to disconnect the AVR output (H2-H4) and have an external device control the reactive power (CT droop...).

  • Page 54: Multiple Generators With Static Paralleling

    8.5 Multiple generators with static paralleling This mode is useful when you urgently need to start a full plant with multiple generators. The generators will be ready to take load in the shortest possible time. This mode is also very useful when your installation includes high voltage transformers. Starting generators which are paralleled together gives a progressive magnetization without peaks (no transient short-circuit).

  • Page 55: Table 13 - Paralleling With Mains

     One GENSYS 2.0 per generating set.  CAN bus must be connected between GENSYS 2.0 units.  An "Excitation" output (e.g. exit C1) must be configured on each GENSYS 2.0 unit.  Generator breaker must be powered by 24VDC (so as to close without AC).

    When remote start is on, the generator starts, synchronizes and parallels with the mains, then takes the load (ramps up). Once the mains are unloaded, GENSYS 2.0 opens the mains breaker. (See Figure 26) When remote start is off, the mains takes the load in the same way as the generator did previously. If the generator started for a mains failure, when mains power returns the GENSYS 2.0 synchronizes the load...

    Permanent mode When the remote start is on, GENSYS 2.0 starts the generator, synchronizes and parallels with the mains, then ramps up load until it reaches its set point. (See Figure 28 & Figure 29) In base load mode (E1153=2), the generator has a constant load and the mains take the utility load variations.
