mAI085-MB Actuator Interface Technical Manual /1 1. Overview The mAI085-MB Actuator Interface is an interface between the control room operator and a network of Actuator Controllers. The interface is capable of controlling up to 100 actuators, either on a single network of up to 31 controllers or through a series of network drops utilizing RS485 repeaters. The interface allows for the pre-setting of setpoints for each of the actuators. An open key opens all of the actuators to their preset setpoints.

mAI085-MB Actuator Interface Technical Manual /16 5.3.1 Main Menu The Main Menu allows the selection of several sub-menus and selection of the global parameter functions. All Main Menu items require YES/no responses. Display Function Response LoC Go to the local interface parameters menu. YES/no CtL Go to the configure actuator controllers menu. YES/no bUs Go to the configure ModBus RS232 interface menu.
mAI085-MB Actuator Interface Technical Manual /17 Display Function Response second YES response starts the operation. The upper display indicates the controller address and the lower display the result of the query. All addresses marked active are queried. Once complete, the lower display shows DonE. Should an active actuator controller not be found, the lower display will show FAiL. Each active address is tried 5 times.
mAI085-MB Actuator Interface Technical Manual /18 5.3.2 Local Menu The local menu allows the configuration of parameters specific to the mAI085-MB. Display Function Response oPn Selects the Open/Close mode at startup. Selecting YES will start the interface with the OPEN lamp on. Selecting no will start the interface with the CLOSE lamp on. The default value is no. YES/no oPL Selects the open relay output pulse timing. See “Controlling Conveying Systems” for details on output pulse timing.
mAI085-MB Actuator Interface Technical Manual /19 A menu selection allows the remote calibration of the field actuator controllers. This function sets the field controller into calibration mode and alerts the operator when the calibration is complete. Before this menu can be entered, the specific controller to be configured must be selected. When entering this menu the upper display will show C 0, indicating controller address 0. Use the upper arrow keys to select the controller to be configured.
mAI085-MB Actuator Interface Technical Manual /20 Display Function GEt Response Get the operational parameters from this controller. A YES response displays SUrE in the lower display. The second YES response starts the operation. Once complete, the lower display shows DonE. Should the controller not respond, the lower display will show FAiL.. YES/no ***************************** WARNING ******************************** This function will overwrite the Interface’s saved copy of the parameters.
mAI085-MB Actuator Interface Technical Manual /21 Display Function Response This function will modify the actuator controllers saved parameters. Verify that the calibration sequence completed successfully and that the actuator is operating properly before placing the field device into service. Actuator controllers that do not complete the calibration sequence revert automatically to the pre-calibration parameter table saved in the actuator controller.
mAI085-MB Actuator Interface Technical Manual /22 5.3.5 Factory Values Menu The Interface can be configured to a range of factory preset values. The menu items allow the selection of the actuator controller model, speed of actuator operation and actuator accuracy. When the save function from this menu is executed all of the controller ID’s will be reset to A1 – A100 and all of the controllers except controller 1 will be made inactive.
mAI085-MB Actuator Interface Technical Manual /23 5.3.6 Diagnostics Menu The mTI085 has a built in diagnostics system. This menu allows for the diagnosis of the input ports, communications ports and keyboard. Test connectors are required to test the communications port. Press the SETUP key to exit any of the diagnostic tests. Display Function io Response Tests the supervisory inputs and outputs. Once selected, energizing a supervisory input will close the corresponding supervisory output, i.e.

mAI085-MB Actuator Interface Technical Manual /25 6. The Input / Output System The mAI085-MB Actuator Interface has 4 discrete inputs and 4 discrete outputs. Figure 2 and Table 2 detail the physical connections to the discrete signals. Each of the signals is described below: Name Description Input 1 Pin 1 Energizing this input will select Open mode and turn on the OPEN indicator on the front panel.
mAI085-MB Actuator Interface Technical Manual /26 Name Description Output 3 Pins 5 & 6 This output will be energized any time all of the actuator setpoints are 0. The output de-energizes whenever a non-zero setpoint is entered into any of the actuators. Output 4 Pins 7 & 8 This output is energized whenever an internal fault is detected in the mAI085-MB Actuator Interface. Possible faults are invalid parameter table (checksum verification failed during startup), corrupted firmware or damaged hardware.
mAI085-MB Actuator Interface Technical Manual /27 7. Controlling Conveying Systems The mAI085-MB Actuator Interface allows the direct control of simple conveying systems. The interface has several timers that facilitate this control. These timers in conjunction with the discrete output system control the conveying system. The following timers are used: ID Description Menu oPL Provides a pulsed output from Output 1 to start a conveying system.

mAI085-MB Actuator Interface Technical Manual /29 8. Using the Modbus Network Interface The mAI085-MB incorporates a RTU Slave Mobus interface. This interface responds to only 3 Modbus slave commands. The commands are 3 - Read Holding Registers, 6 - Write One Holding Register and 16 - Write Multiple Holding Registers. The Modbus protocol allows a maximum of 125 Register Reads and 100 Register Writes in a single transaction. The following tables provide the register assignments for the Modbus interface.

The process value will occupy bits 0 11 of the process value word.
mAI085-MB Actuator Interface Technical Manual /31 8.2.2 Read-Write Registers Each controller has one register for the setpoint value. The setpoint value will occupy bits 0 11 of the setpoint value word. The factory set range of the setpoint value will be from 0 - 100, signifying 0 - 100%. Writing a setpoint to the setpoint register will cause the actuator controller to immediately position the actuator. The value in the setpoint register must change to initiate a move.
