General description
2.1
Introduction
ES 4i Elektronikon II and Elektronikon III regulators of the fourth generation (MkIV) can be used to control up to 4 compressors in order to regulate the air net pressure within programmable limits by automatically starting, loading, unloading and stopping the connected compressors. This so-called ES 4i functionality (also referred to as MCC, abbreviation of Multi Compressor Control) is an integrated feature of the mentioned regulator types. A dongle (part number 8092 2482 62) is required to activate this extra feature. On the regulator display this function is shown as MCC (Multiple Compressor Control).

Local Area Network (LAN) The compressors to be controlled must be connected with each other in a Local Area Network (LAN) using CAN (Controller Area Network) technology. Elektronikon I, Elekronikon II and Elektronikon III regulators (Mk IV) can be directly connected to the local area network (LAN). The regulator with the integrated ES 4i (MCC) function and the dongle serves as master regulator for the compressors. The dongle must be connected with the regulator of this compressor, using the free I/Oconnection. The regulators of the other compressors act as slave regulators. Elektronikon I regulators can only serve as slave. Apart from load/unload controlled compressors, also one VSD (Variable Speed Driven) compressor can be integrated in the MCC network. Besides Elektronikon Mk IV regulators, also Mk I, Mk II, Mk III and relay-regulated compressors can be connected to the network by means of a conversion box and/or a communication module between regulator and network (see the next chapters for details). Select the compressor regulator which will serve as the master regulator for all compressors in the LAN and label this compressor as Master Compressor 1. Select the compressor regulator(s) which will serve as slave regulator(s). Label this (these) compressor(s) as Compressor 2, 3 and 4 respectively. More information about how to set-up a compressor network can be found in document 9820 3582 00.

Installation instructions
3.1
Connecting machines equipped with a MkIV controller Always stop each compressor and switch off the voltage before making any connection! Remember that Elektronikon I regulators can only act as slave, because they do not have the ES 4i feature. In case expansion modules are provided, the dongle must be plugged in into the I/O connector of the last expansion module.
Except for the first version of the Elektronikon I (part numbers: see below), all electronic control modules of the fourth generation (MkIV), i. e. Elektronikon II or Elektronikon III can directly be connected with each other using the LAN port as shown in below figure:

Connecting of Atlas Copco machines with an Elektronikon MkIII regulator This generation of the Elektronikon® regulator came in two variants: a Low Range and a High Range version. One of the key differences between these two regulators are the communication possibilities. The details below explain the possibilities for each variant. • Elektronikon® MkIII Low Range regulator (part number 1900 0700 0x): There are two connection possibilities for this regulator:
12
2920 7048 01
Instruction book
• Via a CANBox interface (part number 1900 0712 61), which in turn is connected to the LAN to communicate with the ES 4i master regulator (see the figure below) • hardwired directly to the ES 4i master regulator In both cases some simple changes are required inside the electrical cubicle. More specifically, two relays must be added, one for the signal running status and the other for the signal load/unload status. • Elektronikon® MkIII High Range regulator (part number 1900 0701 0x). Here also are two possibilities: • The regulator includes an extra module known as COM 1 • The easiest way to connect the machine to the ES 4i master is to add a ComBox S interface (part number 8092 2482 54) which converts all communications to the LAN. • Alternatively the compressor can be hardwired directly to the ES 4i. • If the machine does not include a COM 1 module there are two possibilities: • Use both a COM 1 (part number 8104 0115 00) and a ComBox S (part number 8092 2482 54) • Use a CANBox interface (part number 1900 0712 61).

Operation
5.1
Remarks
Local start/stop function All local start and stop functions on the control panels of the compressors are disabled, except for the emergency stop buttons which remain active. Clock functions In case time-based automatic start/stop commands were programmed in the regulators of the participating compressors (via menu Clock function), these commands will not be taken into account. Variable Speed Driven Compressors In case a VSD compressor is participating, it will start first and the set point and stop levels will change as follows: • The set point will be in the middle of the net pressure band. • The Indirect stop level will equal the maximum level of the net pressure band. • The Direct stop level will equal the sum of the new Set point and the programmed direct stop level of the VSD compressor; the direct stop level must be higher than the Indirect stop level. Example: Pressure band levels programmed in the master regulator: max. 8.0 bar(e) - min. 7.0 bar(e) and Direct stop level programmed in the regulator of the variable speed compressor: 1 bar In LAN configuration, the VSD compressor will have a Set point of 7.5 bar(e), an Indirect stop level of 8.0 bar(e) and a Direct stop level of 8.5 bar(e).

6.1
Creating a new input
Introduction By default, the MCC master regulates the compressors based on its own compressor outlet pressure, i.e. the pressure measured by the pressure sensor in the master compressor. It is however also possible to use another input device (a remote pressure sensor) as the regulation input. Creating a new input can be done using the service and commissioning software (FSP) for MkIV. For more details, see the FSP user manual (can be found via LN in the Elektronikon Software Market database). After creating the remote sensor input, the MCC function must be linked to this input. This can be done using the same service and commissioning software (FSP) for MkIV. Creating a new input for a Kavlico pressure transducer If no spare inputs are available on the Master Module, first an AIE1 expansion module must be linked to the master module. The AIE1 module (part number 1900 0710 41) adds 2 pressure inputs to the MkIV controller. Important note: before physically connecting expansion modules, switch off the power, the same way as for connecting the MCC dongle!
Instructions for FSP: • Activate the Advanced or Full Access level. • Click on the box before AIE1/AIE2 Expansion and select the type of expansion box. Be sure that the compressor is on local control.
• => Add a pressure input function:
• Next, select ‘System pressure’ from the list and click OK: 2920 7048 01

Next, enter text to define the input and program this data by clicking on the Save button:
On the MkIV regulator, you can now check the new pressure input: The ‘Extra’ information screen of the master regulator now shows ‘D 2 K’ where D=type of master module, 2=AIE1 expansion module and K=MCC dongle. In the list of ‘Measured data’ the input ‘Net Pressure’ is indicated. Creating a new input for a pressure transmitter It is also possible to use a pressure transmitter as pressure sensing device. In this case, first an AIE2 expansion module must be linked to the master module. The AIE2 module (part number 1900 0710 52) adds 4 transmitter inputs to the MkIV controller. Remember that transmitters must always be powered by an external supply. Important note: before physically connecting expansion modules, switch off the power, the same way as for connecting the MCC dongle!
Instructions for FSP: • Activate the Advanced or Full access level • Click on the box before AIE1/AIE2 Expansion => select the type of expansion box.
• Add a pressure input function
