What to do if my Hach SC4500 will not power up?
If the Hach Controller isn't powering up, ensure the power cable is securely connected to the controller and that all power connections are properly terminated. Verify that the power strip, line power, and wall plug are correctly plugged in. Also, confirm that the controller is connected to the appropriate power source: 100-240 VAC for AC controllers or 18-28 VDC for DC controllers.
What to do if my Hach Controller firmware update failed?
If the firmware update on your Hach Controller failed, remove the USB flash drive and redo the firmware update process. Download a new firmware update file, ensuring it exceeds 300 Mb.
What to do if my Hach Controller restore firmware failed?
If the Hach Controller firmware restore failed, and you received error code 1, try to restore the firmware again. If you see error codes 2, 3, 5, or 6, a firmware restore is not possible. If you get error code 4, it means you can only revert to the firmware version installed before the update; downgrading further isn't allowed.
Why is my Hach Controller showing 'Unknown device connected'?
The 'Unknown device connected' message on your Hach Controller may appear because the rotary switch of the sensor module is not set correctly, so set the rotary switch of the sensor module to the correct position for the sensor type. Another cause could be that too many devices are installed. Make sure that only two input devices are connected to the controller. Also, make sure that the analog module and the digital sensor are not connected to the same channel. Check the sensor and the sensor cable for damage. Disconnect the sensor, wait 15 seconds, then connect the sensor again. Finally, make sure that the sensor version is applicable to the controller.
Why is the Claros connection icon crossed out on my Hach SC4500 Controller?
If the Claros connection icon is crossed out on your Hach Controller, and you have internet access, ensure the controller is provisioned in Claros if it's the first time connecting. If it was previously connected, try turning the controller off and then on again. Examine the controller connectivity.
What to do if my Hach Controller does not recognize the USB flash drive?
If the Hach Controller isn't recognizing the USB flash drive, verify that it's formatted with FAT32 and has a minimum capacity of 350 Mb. Note that the USB port on the controller is compatible with USB 2.0 devices; USB 3.0 devices are also compatible but will have USB 2.0 transfer speeds. Try using a more recent USB flash drive.
How to fix navigation issues on the Hach Controller touchscreen?
If you're experiencing navigation issues on the Hach Controller touchscreen, clean the screen. The manufacturer recommends regular cleaning. Make sure that the screen is locked during cleaning to prevent unwanted touches.
Why is the NTP service unreachable on my Hach SC4500 Controller?
If the NTP service is unreachable on your Hach Controller, ensure that there are no restrictions to external access in the controller network. Contact your IT department to verify that the network has access to the internet NTP service. Also, ensure that UDP port 123 is open and the Pool.ntp.org address is approved in the network.
Why is the Claros icon off on my Hach SC4500?
If the Claros icon is off on your Hach Controller, it could be due to no internet access. For cellular internet access: Examine the controller connectivity, examine the cellular signal strength (move the USB box to a location with higher signal strength), examine the SIM card settings (provider, APN etc.), make sure that prepaid SIM card has credit, and make sure that the SIM card data volume is not exceeded. Another reason could be no access to Claros. Make sure that the sensors and devices are correctly connected and provisioned in Claros.
Why is there no relay activation on my Hach Controller?
