Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you. Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment. We'll send you an email letting you know exactly when your piece of equipment will be available for viewing.

There is an error message on the LCD display of the old style Infinet controllers. What do these errors mean? This message indicates that the controller received a bad packet of data on the Infinet. If the problem persists follow troubleshooting instructions. Infinet controller is displaying error 2 on its LCD display. This message means that it could not pass a token to another controller on the Infinet. No response to the Infinet token pass. Infinet controller is displaying an error 3 on its LCD display.

This means that the input reference voltage is out of range on the analog inputs. Infinet controller is displaying an error 4 on its LCD display. This means that the analog output reference voltage is out of range. Infinet controller is displaying an error 5 on its LCD display.

This indicates the controller underwent a reset of power down and retained memory warm start. If there is not reason for this to occur power outages etc. Have a question? Please contact us with details, and we will respond. Sign In Help. Home Collaborate.

Verify Infinet cable connections, approved twisted shielded pair cable, less than feet of network cable between Infilink repeaters, no more than 31 controllers between Infilink repeaters. Verify proper grounding at the Infinet controller on the AC power terminals, poor grounding can cause erratic operation and communication problems. Easiest method to verify ground is to connect a digital voltmeter between the earth ground terminal on the power strip of the controller and the shield of the Infinet.

Check the baud rate switch on the Infilink repeater module, although the Infinet controllers auto baud, the Infilink baud rate must be manually switched. Break down the network in segments to identify the bad controller or network segment.

A binary search is recommended. Once the offending segment has been identified, troubleshoot to the cable segment or controller level Infinet controller is displaying error 2 on its LCD display. No response to the Infinet token pass Verify Infinet cable connections, approved twisted shielded pair cable, less than feet of network cable between Infilink repeaters, no more than 31 controllers between Infilink repeaters. Once the offending segment has been identified, troubleshoot to the cable segment or controller level Infinet controller is displaying an error 3 on its LCD display.

Verify that inputs coming from external transducers are not exceeding the voltage input range, either 5 or 10 volts depending on model, if so use a voltage divider on the input. Verify that any input wiring is not run in the same conduit as high voltage cable, or is properly shielded and grounded. If there is voltage getting coupled into the input wiring, separate the input wiring from the interference, or shield the cables.

If the interference is being caused by the end device such as an auxiliary contact form an high voltage device, a cap between. Power down the Infinet controller and restart while connected to network. This will eliminate this unit having a duplicate ID on the network and it will also run the power up diags.

Typically 24 VAC power that is daisy chained will drop the voltage along the connections leaving the power below the acceptable level even if the transformer is sized correctly.

Verify that any outputs that are driving inductive loads such as relays, actuators, or valves, have a varistor across the coil n the field device.
