| Alarm Message | Symptom | Action(s) |
| Thermocouple Failure Channel # | Thermocouple is failing or disconnected |
Ensure proper connection to TB6 for Channel 1, TB7 for Channel 2.
Replace K-type thermocouple. |
|
Water Slip Alarm |
Water has slipped passed the thermo-electric cooler and tripped the water slip sensor. |
Ensure system loading (gas flow and water %) does not exceed cooler capacity. |
|
Verify that the cooler last impinger is holding a constant temperature near 5°C. If a dry sensor still trips the alarm, clean the sensor or replace if necessary. |

|
Overtemp Alarm |
Cooler channel does not maintain a temperature below 10 degrees C. |
Verify that the system loading (gas flow and water %) does not exceed the cooler capacity. Verify that each Peltier element is drawing approximately 6 Amps. Replace the Peltier element if the current draw is low. Calibrate the temperature inputs using a thermocouple simulator. |
|
Probe Overtemp Alarm |
Probe temperature has exceeded the Max Set temperature for the probe. |
Max temp is set too low. Adjust accordingly. Inlet gas sample temp is too high. Consider installing a cooling spool piece before the probe. Inspect for wiring problem that is not allowing the controller to properly maintain temperature. |
| Probe Undertemp Alarm | Probe temperature is below the Minimum Set temperature for the probe. | Minimum set temperature is too low. Adjust accordingly.
On initial startup, the Heated Probe was initially below the minimum temp, but now is above minimum. Press reset to clear the alarm. The isolated power source for the heater is disconnected or off. The heater is failing, causing the probe to not hold temperature. Inspect for wiring problem that is not allowing the controller to properly maintain temperature. |
| Heated Line Overtemp Alarm | Heated Line temperature has exceeded the Max Set temperature for the line. | Max set temperature is too low. Adjust accordingly.
Inlet gas sample temp is too high. Consider installing a gas cooling spool piece before the probe. Inspect for wiring problem that is not allowing the controller to properly maintain temperature. |
| Heated Line Undertemp Alarm | Heated Line temperature is below the Minimum Set temperature for the line. | Min set temperature is too low. Adjust accordingly.
On initial startup, the Heated Line was initially below the minimum temp, but now is above minimum. Press reset to clear the alarm. The heater is failing causing the Heated Line to not hold temperature. The isolated power source for the heater is disconnected or off. Inspect for wiring problem that is not allowing the controller to properly maintain temperature. |
| No LCD or LED(s) and no fan. | AC power input.
DC 3A fuse (F1) on control board. AC 15A fuse on power supply. Check for +15VDC at P1 & P11 of control board. |
Ensure that AC power is connected.
Replace fuse as necessary. Replace fuse as necessary. If low reading, remove wires from P1 & P11, measure at power supply and replace supply if voltage |
| Heat exchanger remains at ambient temperature. | Peltier element current draw. (Should be above 6 amps) |
Replace Peltier element. |
| Heat exchanger frozen and cooler indicates ambient temperature. | Thermocouple placement in heat exchanger block.
Peltier current draw (>6A) for both elements on that channel. |
Ensure proper placement.
Replace Peltier element. |
| Impinger does not reach set temperature, but is below ready temperature. | System loading.
Calibration and set temperature adjustment. |
Ensure system loading is not exceeding cooler capacity.
Adjust as necessary. |
| Heat exchanger temperature cycles up and down. | Peltier element connections on control board.
Ferrite beads on thermocouples going into terminal TB1 & TB2 |
Ensure a firm connection on flag connectors on control board. Ensure system loading is not exceeding cooler capacity.
Wrap a Ferrite bead around thermocouple |
| Water carryover in system. | Heat exchanger temperature. (Should be below 6°C.) | Ensure system loading is not exceeding cooler capacity. |
| Pump does not start. LCD(s) are green. | Pump electrical connections. | Ensure proper connections.
Replace relay board. |
