Corrections:

• False LD stop could be provoked in G7 island operation in case DG was performing load share ramp. No PM backward compatibility is compromised due to this update.
• Mains power indication on superVision in island mode of operation always displayed zero. No PM backward compatibility is compromised due to this update.
• Synchronising last open BTB located furthest to the right in a ringbus application could fail. In case mains connected to busbar on its left side and DG(s) on its right side, the DG(s) would not receive the command of performing synchronisation. No PM backward compatibility is compromised due to this update.
• Last 2 open BTBs in a ringbus application could both initiate synchronisation at the same time in SEMI auto and consequently close at the same time, even though closed ring was not allowed. No PM backward compatibility is compromised due to this update.
• Capacity overrule did not work in case "Start engine" was selected and mains configured with MB and TB. No PM backward compatibility is compromised due to this update.
• Incorrect M-Logic interpretation corrected.
• CBE sequence updated so the excitation relay is kept energised throughout the cool down sequence in case voltage is present on the busbar.
• GB(s) could trip unexpectedly in applications with mains without TB. Phenomenon could occur in case MB was performing back synchronisation and experienced an MB close failure. No PM backward compatibility is compromised due to this update.
• Part of positive sequence alarm did always look at BB voltages though the device type demanded it to act on gen. voltages.
• If doing LTO without sync. to mains or AMF with "Start engine", MB would trip when DG volt./freq. okay, although the DG was performing initial idle sequence. Now MB waits until DG is ready.
• Correction to idle sequence when idle stop not used.
• DG not being under PMS control was still contributing to power summations used as basis for power reference calculations. PM backward compatibility is compromised due to this update in respect of taking DGs out of PMS control.
• When synchronising BTB to external/unknown voltage source, the DGs online would not always react according to synchronisation command sent from the BTB. No PM backward compatibility is compromised due to this update.
• M-Logic command "Start and Close GB" was ignored during cool down.
• Idle run could elapse more than once during start sequence.

New features:

• Idle run supported in emulation.
• Functionality for limiting amount of nominal power allowed on busbar at a time due to limitations of short circuit current expanded to be included in the system logics of the DG and mains.

Includes versions: 1.01.4 & 1.12.0.

N-option compatibility: As a minimum, SW version 2.00.3 is needed due to exceeding of limitation of 4000 text strings.

Corrections:

• It was not possible to clear fast alarms such as vector jump on a mains unit in case no mains voltage was present.
• The resolution of fixed power reference sent from the Mains unit to the DG(s) was ependent on the power measurement resolution of the Mains unit itself. In case Mains unit used caling range [10-160 kV] for instance, the fixed power reference sent to DG(s) were in 1/10 of MW accuracy.

Changes:

• Ground Relay functionality modified. Close command to the ground breaker has been postponed from being send at start up to being send when generator voltage and frequency
  is within operating range.

• "Oil filter differential pressure" added as selection in Delta Analogue alarms.

Corrections:

• If "DG missing" alarm was present as well as G3 option the unit would switch to analogue var-sharing. Now the automatic switching is removed and the user have to use the M-logic event Analogue Loadsharing and this give both var-sharing and kW-sharing.

Changes:

• Ground Relay handling updated. Ground Relay activates as DG start up and remains activated until GB closed. Ground relay will open again in case GB closed and larger DG being on busbar and not preparing to disconnect has Ground Relay active. PM compatibility compromised in respect to GroundRelay functionality. Code prepared for breaker feedback handling though so support of this should be possible to implement without further compromising of compatibility.

Includes versions: 1.00.0, 1.00.1, 1.00.2 & 1.10.0.

New features:

• In emulation mode the Fuel Pump Logic functionality is now coupled to the emulated fuel level which enables it to fill up the fuel tank.
• Possible selections for Fuel Pump Logic Input type expanded to include M15_X options as well as external analogue inputs.

Corrections:

• Initialization of internal communication could some times fail at power up resulting in "internal comm." alarm.
• Initialization of N-option could some times result in garbage/missing parameter data after firmware update.
• A normally closed Vac BTB being in AUTO and ready to close, but unable to do so due to missing BA and BB voltage, could block for other BTB in the system to perform automatic closing. No Backward compatibility is compromised due to this update.
• Incorrect voltage reference would be used by DG(s) when synchronizing a BTB against Mains connection(s). Phenomenon occurred when BTB was synchronizing with DG(s) connected to busbar on one side and only Main(s) connected to the other.  No Backward compatibility is compromised due to this update.
• Heavy consumer was corrupted due to optimization made in version 4.00.0. Error now corrected. Backward compatibility towards older PM versions remains compromised.
• Overlap functionality did not work in emulation mode

4.00.0

06/12/2011

PM compatibility version 1.10.0
Includes versions 1.00.0 and 1.00.1

Features:
1- Option G7 “Plant Management” introduced. Two new product types introduced in this context:
a. Gen-set group tie unit.
b. Plant unit.
2- Option "Emulation" introduced.
3- Option H9 "modbus RS232" introduced.
4- 4 different voltage/power scalings introduced covering range from 10V/1.0kW up to 160kV/900.0MW.
It is possible to have controllers using different scaling within a power management application.
Contollers having PM compatibility version 1.00.0 or newer are able to understand if other
controllers are using scaling even though they are inable of performing scaling themselfes.
5- Separate settings for nominal busbar voltage introduced enabling synchronization over step
up/down transformers.
6- Menu7054 in Mains unit for enabling common cosphi reference to DG(s) expanded.
Possibility of making cosphi reference for DG(s) load dependent to hold fixed cosphi across MB
added:
a. Off (DG, Mains, Gen-set group tie and Plant units).
b. Fixed for DG(s) (Mains, Gen-set group tie and Plant units).
c. Fixed for imp/exp (Mains, Gen-set group tie and Plant units).
d. Superior (DG and Gen-set group tie units).
No PM backward compatibility is compromised.
In fact DG(s) with older PM compatibility versions will be able to handle if “Fixed for imp/exp”
is selected in the Mains unit. “Superior” is the setting used for taking in cosphi reference
from unit placed at higher level in the system. If for instance DG(s) are to take in reference
from a Mains unit, “Superior” must be selected in the DG(s).
If DG(s) are to use their local reference the setting must be set to “Off”.
In case “Fixed for imp/exp” is selected in a Mains unit it will seek to compensate for any DG(s)
not being in “Superior” to maintain the requested cosphi across its MB. DG(s) with older PM
compatibility version will behave as if “Superior” was selected and will therefore only use
local reference in case no reference is received from the mains unit.

• Load profiled running hour counter added. This counter is weighted with the percentage load of the DG.  This counter is selectable as type of running hour on which to base DG priority in menu8113:  a. Total. b. Trip. c. Load profiled. Load profiled selection will not be compatible with units having older PM compatibility versions.

• Priority handling updated. Now it is possible to make manually update of priorities in Menu8086 depending on either user defined priority order or according to running hours. a. Off. b. Manually update. c. Running hour update. This is independent on priority routine selected of the type selected in menu8113. No PM Backward compatibility is compromised due to this update.
• Possibility of subtracting DG(s) from Power Management system added. It is now possible to select a Gen-set mode in menu6071 other than “Power management”  when being part of a Power Management application. When doing so normal operation of a SingleDG will be obtained.  The DG(s) will no longer be available to the Power Management system.  The Power Management communication itself will remain intact and no alarms will be introduced in the system.  No PM backward compatibility is compromised due to this update.
