What to do if the Leakwise ID-220 Controller LCD and power light are off?
- M
  Ms. Sarah ThorntonAug 13, 2025
  If the LCD and/or power light are off, and there's no 4-20mA output or relay output change, check the following: * Verify the connection to the mains or power source and ensure the internal on-off switch is on. * Confirm the power supply conforms to the required specifications. * Check the wiring against the wiring diagram. * Inspect the relays: if the small LED on the left side of the relay doesn't change as expected, replace the faulty relay or the outputs board.

How to fix a Leakwise ID-220 showing an OIL indication when there is no oil?
- K
  Kristin FinleyAug 21, 2025
  If your Leakwise Controller indicates oil presence when there is no oil, consider these potential causes and solutions: * Ensure the sensor is installed vertically. * If the sensor "jumps" due to turbulence, install the sensor assembly in a stilling tube or increase the response delay. * Check for and carefully release any entanglement of the flexible cable between the sensor and the stilling cage. * Recalibrate the system.

- J
  James HenryAug 25, 2025
  If the remote recorder receives less than 20mA when 20mA is expected, check the following: * Verify the analog output settings according to chapter 2.2.3. * Ensure the load is below 400 ohms; reduce it if necessary.

Why Leakwise ID-220 won't communicate with PC using SLC-Manager?
- C
  Christopher CarpenterAug 28, 2025
  If you are experiencing communication issues between the Leakwise Controller and the PC with the SLC-Manager program, consider the following: * Verify that the serial port is set to 115200 Baud, 8 data bits, 1 stop bit, no parity, and no flow control. * Check the integrity of the communication cable and ensure correct connection of Tx and Rx wires (straight connection, not crossed).

Why is the FAIL indicator on for my Leakwise ID-220 Controller?
- P
  Paul DiazNov 16, 2025
  The FAIL indicator may be on due to several reasons: * A faulty sensor. Check each channel to identify the faulty one. Try connecting the sensor to a known good channel to isolate the problem. * Improperly connected sensor. Verify the sensor cables against the wiring diagram. * Sensor out of calibration. Ensure the sensor signal is within the AIR and WATER limits; otherwise, recalibrate the channel. * Abnormal signal output from the sensor due to malfunction. Disconnect the sensor, connect it to an external 12 VDC power supply, and measure the DC current. Compare the readings to the Sensor Test Certificate. If they don't match, contact your distributor. * If safety barriers are installed, a safety barrier failure may have occurred. Check the resistance between points 1 and 3 of ...
