User’s Manual Miller Receiver
1. DESCRIPTION The Miller Receiver have a Solid-State Main Contact (AC/DC), two analog inputs, one scalable analog output (0~10Vdc, 8-bit resolution), 2.4GHz frequency, with address learning. A Watchdog IC for monitoring and resetting the Micro Controller. The Receiver works in combination with the Miller Foot Control and Miller Hand Control. Note: Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference that may cause undesired operation of the device. 2. TECHNICAL SPECIFICATIONS Note: The user is cautioned that changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

3. FUNCTIONAL DESCRIPTION 3.1. Receiver Operation • The main power supply is 12 to 30Vac coming from the welding machine. This supply is also used as the supply for the Main Contact output. • The DK assigned for the relay output is configurable. By default, it is assigned to DK3 that is the safety-DK transmitted by the M-TX and M-Mini-TX boards. • The time for the relay output to turn ON (ON delay) and to turn OFF (OFF delay) is adjustable. By default, there is no delay set (ON delay = 0ms, while OFF delay = 0ms). • The DC analog output is controlled by the 8-bit data (256 steps) and the assigned safety DK. The analog output range depends on the DC supply coming from the welding machine. This reference input supply is adjustable from 0 to 10V. If the reference input supply is set to 1V, the analog output will be 0~1V with the same 8-bit resolution. The DK assigned to the 8 bits is fixed to DK17~DK24 with DK17 as the LSB. The default safety channel is DK3. • The analog output ramp time is adjustable. By default, minimum ramp time of 100ms is set to make the output increment/decrement transition smooth. Ramp time is the total time for the output to reach maximum when it is initially minimum. Ramp time is only valid while safety DK is active. If the safety DK is turned OFF, the analog output will be set to minimum without considering ramp time. • The receiver is capable of learning the transmitter address and channels using its learning button. Details of this function described on following sections. 3.2. Learning Function The system has a learning function to allow users to pair (bind) a Transmitter to a Receiver’s frequency and address. The procedure to use the learning function is as follows: 1. Bring the Transmitter to within 2 meters of Receiver. 2. Press and hold the learn button on the Receiver. 3. Press Foot Pedal to maximum travel stop and hold for four seconds or adjust Mini-TX display to minimum and hold down button for four seconds. 4. Release the Receiver’s learn switch. 5. The decoder’s green LED will begin blinking rapidly to indicate data is received from the Transmitter and the learning function is complete. 6. For safety the Main Contact will not close until the Foot Pedal is turned on a second time. Learning is only possible during the first 2 seconds that the Footpedal Transmitter is at maximum analog output and the Receiver detects a high level of R.F. strength (indicating the transmitter is within a 3 meter range). After address learning, the Transmitter and Receiver pair combine the Receiver address and Transmitter address to make a unique address to prevent errant Binding with another device. LED Description Receive Mode Green LED Flashing at a rapid interval: Active Telegram is being received. Green LED is toggled every time a valid telegram is received. Green LED toggles slower when receiving from a Mini-TX in standby mode. Idle Mode Green LED on solid.
4. FCC REQUIREMENTS FOR INFORMATION TO THE USER The users manual or instruction manual shall caution the user that changes or modifications to the equipment not expressly approved by the party responsible for the grant of equipment authorization issued by the FCC could void the user's authority to operate the equipment under the grant of equipment authorization: Warning: Changes or modifications to this device not expressly approved by Hetronic could void the users authority to operate the device under the FCC Equipment Authorization. Warning: Co-location of this modular transmitter with any other transmitter is prohibited without a Class II permissive change to both transmitters. 5. OEM PRODUCT LABELING If the label on the modular transmitter is not visible from the exterior of any enclosure into which it is installed, the following label must be added to the exterior of the final product or device, “Contains FCC ID: LW9-MILLER-RX.
