H-Max HVAC Drives Safety Definitions and Symbols Warnings and Cautions WARNING This symbol indicates high voltage. It calls your attention to items or operations that could be dangerous to you and other persons operating this equipment. Read the message and follow the instructions carefully. This manual contains clearly marked cautions and warnings which are intended for your personal safety and to avoid any unintentional damage to the product or connected appliances.
PAGE 13
H-Max HVAC Drives Important Warnings WARNING After disconnecting the AC drive from the mains, wait until the indicators on the keypad go out (if no keypad is attached see the indicators on the cover). Wait 5 more minutes before doing any work on the connections of H-Max. Do not open the cover before this time has expired. After expiration of this time, use a measuring equipment to absolutely ensure that no voltage is present.
PAGE 14
H-Max HVAC Drives Additional Cautions CAUTION The H-Max AC drive must always be grounded with an grounding conductor connected to the grounding terminal marked with . The ground leakage current of H-Max exceeds 3.5 mA AC. According to EN61800-5-1, one or more of the following conditions for the associated protective circuit shall be satisfied: a) The protective conductor shall have a cross-sectional area of at least 10 mm2 Cu or 16 mm2 Al, through its total run.

HVAC Application HVAC Application The Eaton HVAC drive contains a preloaded application for instant use and supports HVAC specific terminology and functionality. In addition, the H-Max drive uses a patented Active Energy Control algorithm. In addition to your drive efficiency, the controller works to minimize losses in your motor throughout the defined speed range delivering industry-leading energy efficiency.

Keypad of the Drive Keypad of the Drive There are two different keypads used with the H-MAX drive. The North American Keypad is slightly different than the EMEA Keypad. Functionality is quite similar. The EMEA keypad does not support the bypass functionality commonly used in the United States. The control keypad is the interface between the Eaton H-MAX frequency converter and the user.
PAGE 23
Keypad of the Drive Keypad Display The keypad display indicates the status of the motor and the drive and any irregularities in motor or drive functions. On the display, the user sees information about his present location in the menu structure and the item displayed. Main Menu The data on the control keypad are arranged in menus and submenus. Use the up and down arrows to move between the menus.

Control Place The control place is the source of control where the drive can be started and stopped.
PAGE 25
Keypad of the Drive Accessing the Control Page The Control page is meant for easy operation and monitoring of the most essential values. 1. Anywhere in the menu structure, push the HOA button. 2. Push the arrow up or the arrow down button to select Control page and confirm with the OK button. 3. The control page appears. If keypad control place and keypad reference are selected to be used, you can set the Keypad reference after having pressed the OK button.
PAGE 26
Keypad of the Drive Copying Parameters The parameter copy function can be used to copy parameters from one drive to another. The parameters are first saved to the keypad, then the keypad is detached and connected to another drive. Finally, the parameters are downloaded to the new drive, restoring them from the keypad. Before any parameters can successfully be copied from one drive to another, the drive has to be stopped when the parameters are downloaded.
PAGE 27
Keypad of the Drive Help Texts The graphical keypad features instant help and information displays for various items. All parameters offer an instant help display. Select Help and press the OK button. Text information is also available for faults, alarms, and the Startup Wizard. Help Text Example STOP READY I/O STOP READY I/O OK STOP READY I/O OK Adding Item To Favorites You might need to refer to certain parameter values or other items often.

Eaton H-Max—Startup Eaton H-Max—Startup Startup Wizard In the Startup Wizard, you will be prompted for essential information needed by the drive so that it can start controlling your process. In the Wizard, you will need the following keypad buttons: Left/Right arrows. Use these to easily move between digits and decimals. Up/Down arrows. Use these to move between options in menu and to change value. OK button. Confirm selection with this button. OK BACK Back/Reset button.

Eaton H-Max—Startup PID Mini-Wizard Multi-Pump The PID Mini-Wizard is activated in the Quick Setup menu. This Wizard presupposes that you are going to use the PID controller in the “one feedback/one setpoint” mode. The control place will be I/O A and the default process unit “%”. If Multi-Pump is the selected application, parameter group 2.12 will be visible in the menu structure. Default values may need to be adjusted to meet your application needs.

Communications Modbus Protocol Modbus General Information Modbus is a communication protocol developed by Modicon systems. In simple terms, it is a way of sending information between electronic devices. The device requesting the information is called the Modbus Master (or the Client in Modbus TCP) and the devices supplying information are Modbus Slaves (in Modbus TCP servers). In a standard Modbus network, there is one Master and up to 247 Slaves, each with a unique Slave Address from 1 to 247.

Communications ID Map Using the ID map, you can read consecutive memory blocks that contain parameters whose IDs are not in a consecutive order. The address range 10501–10530 is called “IDMap”, and it includes an address map in which you can write your parameter IDs in any order. The address range 10601 to 10630 is called “IDMap Read/Write”, and it includes values for parameters written in the IDMap.

Communications Fault History Fault History The fault history can be viewed by reading from address 40401 onward. The faults are listed in chronological order so that the latest fault is mentioned first and the oldest last. The fault history can contain 29 faults at the same time. The fault history contents are represented as follows.
