MainsPro

Order code: MAINSPRO

MainsPro is an easy-to-install mains protection relay for parallel-to-mains applications. It reliably monitors voltage, frequency and loss of mains protections to safeguard both the distribution network and the generators. This protection relay is designed for installations with renewable energy sources such as photovoltaic plants, gen-sets, cogeneration units, and microturbines.
 
  • Reliable measurements evaluation  
  • Three-phase generator voltage measurement
  • Generator and engine protection  

Compliant with international grid codes: IEC 60255, G99, IEn NR 005/2012 and VDE-AR-N 4105

Frequently Asked Questions

Can I unlock my controller?

If you have forgotten your controller password, it can be found using the password decode function.

You will need the following information about your device:

  • serial number
  • "password decode" number
Both numbers can be obtained through the monitoring software relevant to the device.
  • Serial number is available in Controller info
  • Password decode number is available in Values / Info

You can also show these numbers on your device's display. Typically, this requires a sequence or combination of buttons to be pressed. Details can be found typically in the device Operator guide.

Once you have these numbers, please contact your ComAp distributor and they will help you get your password back.

 

How do I connect to my ComAp controller? What types of connections are supported?

ComAp offers a wide range of options to connect to your controller:

  • RS232 / RS485
  • USB - USB A<->B (usually a printer cable)
  • Internet connection - LAN, GPRS, 3G, 4G

Note that some connection types require you to use a communication module (plug-in eg a RS232 card) or communication bridge (external device eg Internet Bridge NT).

Each ComAp device usually allows for multiple ways of connection. The simplest one supported by the majority of our devices is the RS232 (serial) connection. For this, you need an RS232 cable (null modem) and if your PC is not equipped with an RS232 port you need a USB<->RS232 converter.
USB connections are very common. Almost all ComAp devices support connection using simple USB A<->B cable (printer cable) for easy configuration. Some devices can be powered from the USB port for programming to allow easy configuration right on your desk.
Other connection types: Internet connection (LAN, GPRS, 3G, 4G), Modbus RTU, Modbus TCP, SNMP, AirGate, Modem.
Note that some connection types require you to use a communication module (plug-in eg a RS232 card) or communication bridge (external device eg Internet Bridge NT). Not all types of connection are possible on each device. You can find all the details related to this topic in your device's Comprehensive guide or Communication guide.

How do I change the controller firmware? Where can I get the latest firmware?

You can download the latest firmware package on the webpage of the device. You can easily navigate there through the ‘Products’ section or just use the Search function. If you cannot find the firmware on the website or if you require different than the offered version do not hesitate to contact our support team.

The firmware upgrade itself is easy to perform. You need the appropriate configuration software and a connection to the controller (preferably a direct connection). Prior to initiating the update process, we strongly recommend you to save a complete backup of your device.

It usually consists of several steps:
  • Create a controller back up.
  • Update the device firmware. It will contain default Configuration Archive and default Application.
  • Change the Application (SPtM, MiNT, MCB, MGCB, BTB, etc) to the required type (by programming appropriate default archive to the controller).
  • Use the Import Configuration Wizard to restore your previous configuration. In some cases manual interventions might be needed during this step.
  • Optional: Update the connected display firmware or device communication module firmware.
Should you be unsuccessful in programming the new version, the rollback procedure is to install previous firmware version and use your back up to restore the controller to its original state before the firmware upgrade was attempted.

How do I synchronize a gen-set to the mains? What AVRs do you support? What Speed Governonrs do you support?

The ComAp product portfolio includes controllers that can control voltage and speed and with those products our controllers are able to synchronise to the mains.

Synchronizing a gen-set to mains (or multiple gensets to each other) is a procedure which requires the following conditions to be met before you connect the two electrical systems together:
  • Matching voltage in all phases of both systems.
  • Matching frequency of both systems.
  • 0° phase angle between both systems. (Or as close to 0° as possible.)
  • Matching sense of rotation of both systems.
The last condition is predetermined by wiring and needs to be checked prior to commissioning, the rest can be controlled by a ComAp device. In order to do so you need to interface the generator AVR (Automatic Voltage Regulator) and the engine Speed Governor. ComAp controllers designed for paralleling operations typically have outputs designed for this connection. Thanks to this we are able to control the generator voltage and the engine speed (and subsequently phase angle).
 
The procedure of configuring the speed and voltage regulation is described in the relevant documentation. The same document also contains the list of supported AVRs and Speed Governors including the wiring and configuration setpoints.

Firmware and archive/configuration upgrade in ComAp controllers.

Each ComAp controller needs firmware and configuration for its operation.
  • Firmware (FW) = operation system of the unit.
  • Configuration (also called Archive) = application settings/parameters and functions, IOs definition, PLC, ECU, etc. It also contains history log saved from monitoring software (InteliMonitor, LiteEdit, InteliConfig).

New FW (together with default Archives) can be obtained from product page on our website or using the InteliBot’s Download section. After download, you can double click on the file (typically *.psi or *ixc) to import all needed files into your library (in your computer - see below where you can find it). By using configuration tools (such as GenConfig, DriveConfig, InteliConfig, LiteEdit) you can also upgrade the FW of your controller (you need to be connected to that controller, it is recommended over cable).

Default application files are available:
  • directly in InteliConfig „New configuration“ window
  • (typically) C:\Users\Public\Documents\ComAp PC Suite\GenConfig\Archives\Default (or DriveConfig) folder for InteliGen and InteliSys NT units.
If you want to change your IGS-NT unit from SPtM to MINT application, you can simply choose this default file in the configuration SW and write it into the unit.
FW and configuration file version has to match,  (e.g. 4.1.x FW version, you need 4.1.x archive version – 3.9.x would not be allowed to be written into the unit). Configuration/Archive files are usually upgradeable using our SW Tools (GenConfig, DriveConfig, InteliConfig).

We do recommend to use for every new project the newest FW that is available.  In case that you miss or you are not satisfied with some features, you can also upgrade the FW and the archive the newest version.
