Page 28 Notes on Ethernet connection If you change the IP address of a GENSYS 2.0, you should also adapt Windows hosts file to be able to use the hostname (http://gensys/ or any other hostname of your choice) in your Web browser. Otherwise you will have to directly type the IP address of the GENSYS 2.0 you want to connect to in your Web browser.

In this page, the user can choose from among 6 submenus (Genset electrical meters for example). It is also possible to scroll through the other pages of the menu with the << and >> links. The ESC link acts in the same way as the GENSYS 2.0 ESC key: it will display the parent menu.

LED indicates that a voltage other than zero is measured. If a speed governor is connected to GENSYS 2.0, it is possible to increase the speed with the [+] key, and decrease it with the [-] key.
Page 32: Test 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.

1/ When the generating set is running, the Open/Close generating set breaker button will switch the generating set on load. 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).

For the generator to start when mains failure occurs, either a protection (mains or other) or a digital input has to be configured as a "Mains electrical fault". If remote start is on when mains are present the generator starts, GENSYS 2.0 opens the mains breaker, then closes the generator breaker and takes the load.

Page 39: Generators Paralleling With Digital Bus
Table 11 - Typical basic multi Generator configuration In this mode, CAN bus on COM1 “inter GENSYS 2.0" is used to manage the different units on the same bus. This mode has better reliability and accuracy than equivalent analogue solutions.
Page 40: Generators Paralleling With Gensys 2.0 And Parallel Line Modules
Table 13 - Typical basic configuration for GENSYS 2.0 with parallel line modules When GENSYS 2.0 is in ILS compatible 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...). This mode is only recommended for use if you have older devices (which are not compatible with CAN inter GENSYS 2.0), with ILS...
Page 41: Multiple Generators With Static Paralleling
6.5 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 magnetisation without peaks (no transient short-circuit).
Page 42 -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).

Page 44: Figure 22 - Typical Sequence In No Break Co Mode
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. When remote start is off, the mains takes the load in the same way as the generator did previously.
Page 45: Figure 23 - Typical Sequence In Permanent Mode
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. In base load mode (E1153), the generator has a constant load and the mains take the utility load variations.
Page 46: Power Plant Paralleled With Mains Using Master 2.0 Or Gcr
MASTER 2.0 gives a maximum of 13 generators. Mains paralleling mode is fixed to « No changeover » when a single GENSYS 2.0 is used together with one or more MASTER 2.0. To allow Power Factor regulation, the "Mains breaker in" (J1) input to GENSYS 2.0 must be connected. Power Factor regulation is not an option.

Additional modules can be MASTER 2.0 (recommended) or GCR (not recommended for a new installation). MASTER 2.0 uses all-digital technology whereas GCR uses analogue load share lines (sometimes called Parallel Lines).

The set point of the central frequency is the parameter E1080 (or E1081 if selected). When the GENSYS 2.0 starts, one genset is elected to be the master (the first one on the bus). The master determines the central frequency and load sharing is without an integral. The other gensets determine the load sharing with an integral, but without using the central frequency.

The “Operator controlled return to mains” special function (set with the parameter E1620 = 1) allows the operator to control the moment the engine will return the load to the mains.

(norm NF E 37-312). The aim is to inhibit the oil pressure and water temperature safeties on the GENSYS 2.0. Thus, in the case of a fault, the generator remains in operation. Other protections (over speed, overload, etc...) are still active if set.

11.8 Use of BSM II with GENSYS 2.0 When you have a lot of analogue values to monitor, BSM II can be connected to GENSYS 2.0 to log measurements and process data efficiently. This chapter will explain this type of configuration.
Page 92: Figure 48 - Wiring Gensys 2.0 To Bsm Ii
GENSYS 2.0 can be connected to several devices via its COM2: BSM II (Max 2), Wago coupler (Max 32). Only one of the two BSM II must be set to log data from GENSYS 2.0 (limited by the number of messages sent from GENSYS 2.0).

This function automatically controls the start and stopping of several generators of a power plant depending on the load request, whether paralleling with the mains or not. Coordination with the other GENSYS 2.0 units is via the CAN bus (COM1).
Page 97: Figure 51 - Automatic Load/Unload Sequence
A40Z090227. GENSYS 2.0 calculates the power that will remain on the bus bar (in % for each engine remaining) if it decides to stop (and open its breaker). If this percentage is under the required threshold (E1915), then GENSYS 2.0 will stop. If not it will wait until threshold is reached.

GENSYS 2.0 includes 120 Ω termination resistors on COM1 and COM2. These termination resistors can be connected to the CAN bus via DIP switches at the rear of the module. Only the GENSYS 2.0 located at an end of a CAN bus should have its termination resistor activated.
