Maxim III Controller

Digital / Controllers

The Innotech Maxim III Controller is a state of the art digital processing system that has the capability of controlling various types of commercial systems. The Maxim III Controller can operate as a standalone device, using its own universal inputs and analogue and digital outputs to receive information and control external equipment, or as part of a network of Innotech devices that support Global Net Comms.

The Maxim III Controller's configuration program is developed on a computer using a Windows® based program. This allows the user to configure the internal processes of the Maxim III Controller by using a graphical programming tool. The user places various process blocks and interconnecting lines to design the required control algorithm for the system.

The configuration program can be downloaded to the Maxim III Controller with an RS485 serial link, using the connector on the right side of the case to link to the computer via a 485/232 converter, or with an optional Ethernet link, using the RJ45 connector on the bottom right side of the case. These links may also be used to upload logged data or the program back out of the controller for modification or debugging purposes.

Innotech Maxim III Controllers are designed for mounting inside a control cubicle and offer a varierty of inputs and outputs enabling it to monitor and control all types of external plant and equipment. Although the Maxim III Controller is flexible, it is primarily designed for the air conditioning and building automation industry.

Within the Maxim Series Digital Controllers family, the Maxim III provides the highest number of I/O points and the highest memory resources.

The creation of control strategies is made simple by the use of the Maxim Config configuration utility. This utility with its powerful Graphical User Interface allows the user to create an entire control strategy in block-diagram form.

Typical applications include:

Air conditioning and heating systems
Lighting control
Time clock controller
Monitoring device
Distributed I/O points controller
Cold/Freezer Rooms

	CE	https://europa.eu/youreurope/business/product/ce-mark/index_en.htm The CE label is a European marking for products to indicate conformity with the electromagnetic compatibility and health and safety requirements set out in European Union.
	RCM	https://www.acma.gov.au The RCM compliance mark indicates that a device complies with applicable radiocommunication and electrical safety standards.
	UL	https://www.ul.com UL marking for USA and Canada indicates that the product conforms with the safety standards laid down by Underwriters Laboratories.

MaxCon - Maxim Controller Configuration utility. It allows the user to internally configure a Maxim by a simple point-and-click approach on a PC running Windows.
MaxMon - Monitoring and debugging utility designed to help with commissioning and trouble-shooting a Maxim Controller.
MaxSim - Utility that simulates a Maxim II Controller. The virtual Maxim II can be powered on, configured and interrogated in the same way as a physical Maxim II.
iComm- Communications server used by Innotech software to communicate with Innotech digital controllers.
MaxTract - Log extraction utility for a range of Innotech digital controllers. It allows extraction of all or part of the history log data residing on a Maxim controller into a specified data format.
Innograph - Designed to specifically cater for the data log graphing capabilities of Innotech controllers, and it has the flexibility to display data log graphing information from other sources.
Supervisor - A dynamic monitoring utility for Innotech controllers. It provides all the functionality that is available from an Innotech controller display panel with greater ease-of-use and flexibility.
EtherMate - Specialised configuration tool for Ethernet enabled Innotech devices. It provides the functionality to set the RS485 baud rate, serial format and TCP/IP settings.
Magellan - Event-driven, object oriented real-time Supervisory Control and Data Acquisition package. It provides a simple, mechanism to design trivial or sophisticated supervisory or control programs.

Power Supply

24 V AC ± 10% @ 50/60 Hz.
24 V DC ± 10%.

Transformer nominal rating of 10VA.

The operating voltage must meet the requirements of Safe Extra Low Voltage (SELV) to EN60730. The transformer used must be a Class 2 safety transformer in compliance with EN60742 and be designed for 100% duty. It must also be sized and fused in compliance with local safety regulations.

Inputs
20 Universal Inputs configurable via software to either:

Dry Digital Inputs
Voltage Digital Inputs
10k Thermistor Inputs
0-10 V DC
LUX sensor input (Light sensor ORP12 LDR)
Dry Duty Cycle Inputs
Voltage Duty Cycle Inputs
Dry Pulse Counter Inputs
Voltage Pulse Counter Inputs

Notes:

Input combinations may be limited by the device and need to be set in pairs
Input accuracy is ±0.1 volts
Error is less than 0.2% with 15Hz Square Wave input
LUX Sensor Input mode is useful for switching based on ambient light levels, but is not suitable for any operation which requires the accurate measurement or recording of light levels

Outputs

12 Digital Outputs:

12 x normally open relays (2 amp @24 V AC) supplied by a Class 2 Transformer
Recomended use of pilot relays when switching high voltage/inductive loads.

8 Analogue Outputs:
- Can be configured individually as either linear 0-10 V DC or PWM outputs
- Output Load > 2kOhms

Note: Up to 3 solid state relays can be connected in series to the analogue outputs when configured as PWM.

Temperature Ratings

Storage: 0 to 50°C non-condensing.
Operating: 0 to 40°C non-condensing.

Battery
Contains a Lithium Type Battery, Dispose of Properly.
(In accordance with local regulations)

Type CR-2032 Lithium
Nominal voltage 3 Volts
Shelf life: 5 years, dependent on ambient temperature

Caution: Risk of explosion if battery is replaced by an incorrect type.

Enclosure/Mounting
The Maxim III Controller is housed in a rectangular case suitable for DIN rail mounting. The housing is moulded from flame retardant plastics reconised by UL as UL 94-V0.

Colour: Grey
Dimensions (max): 224 mm(w) x 115 mm(h) x 74 mm(d)

Communications

RS485:
5 way plug in connector for local/remote computer access for purposes of uploading, downloading and monitoring configuration programs, and the extraction of logged data via a 485/232 converter.
Ethernet:
An optional RJ45 Ethernet port for PC and Internet access to the Maxim III Controller and other devices connected to it in an Innotech Net Comms network. This has the same functionality as an external RS485 to Ethernet Converter.

Data Logging
The Maxim III Controller comes with a powerful Data Logging facility. Data Logging can be assigned to hardware and software points. Up to 300,000 time stamped readings can be stored on the Maxim III Controller. All data is stored in a 2MB non volatile flash RAM. When the memory becomes full, new readings replace the oldest readings. All logged data points can be extracted by using the MAXtract Software tool.
