DANGER
IT IS STRONGLY FORBIDDEN TO START REPAIRING A DEVICE WHICH IS CONNECTED TO AN AC NETWORK.
If an Error occurs, the System continues to work, information with a description and an alarm code is displayed, and a warning sound signal is turned on.
In case of a Failure, the operation of the Computing Unit is stopped by the Internal Cooling System command with or without delay, depending on the emergency nature. The Internal Cooling System blocks the possibility of Computing unit manual control, information with a description and an error code is provided on the display, and an audible alarm.
In case of error: intermittent sound signal. It is possible to disable the sound by simultaneously holding both of the buttons for 2 seconds.
In case of an accident: continuous sound signal. It is disabled only when the Computing unit is completely turned off.
| PROBLEM | POSSIBLE CAUSE | SUGGESTED SOLUTION |
|---|---|---|
¶ F311 |
STM sensor is fault or out of range | Reset controller in STANDBY mode via Commands menu or shut down Device and de-energize all PSUs. If this problem repeats, please contact the Manufacturer. |
¶ E312 |
T1 liquid inlet sensor is fault or out of range | Reset controller in STANDBY mode via Commands menu or shut down Device and de-energize all PSUs. If this problem repeats, check if the NTC1 sensor is connected to the Controller correctly. If this problem still remains, please contact the Manufacturer. |
¶ F313 |
T2 liquid outlet sensor is fault or out of range |
Reset controller in STANDBY mode via Commands menu or shut down Device and de-energize all PSUs. If this problem repeats, check if the NTC2 sensor is connected to the Controller correctly. If this problem still remains, please contact the Manufacturer. It is allowed to temporarily swap NTC1 and NTC2 sensors to make Device work in case of emergency. |
¶ E314 |
T3 air inlet sensor is fault or out of range | Reset controller in STANDBY mode via Commands menu or shut down Device and de-energize all PSUs. If this problem repeats, check if the NTC3 sensor is connected to the Controller correctly. If this problem still remains, please contact the Manufacturer. |
¶ E315 |
T4 air outlet sensor is fault or out of range | Reset controller in STANDBY mode via Commands menu or shut down Device and de-energize all PSUs. If this problem repeats, check if the NTC4 sensor is connected to the Controller correctly. If this problem still remains, please contact the Manufacturer. |
¶ E316 |
T5 temperature and humidity (on-board I2C) sensor is fault or out of range | Reset controller in STANDBY mode via Commands menu or shut down Device and de-energize all PSUs. If this prob- lem repeats. If this problem still remains, please contact the Manufacturer. |
¶ E321 |
Up to 2 fans fault (Some of fans fault, at least one is alive) |
Reset controller in STANDBY mode via Commands menu or shut down Device and de-energize all PSUs. If this problem repeats, check if the faulty fan is connected to the Controller properly. Ensure, there is nothing preventing fan rotation. It is allowed to swap fans connectors between Controller headers FAN #1-6 to ensure there is no problem with Controller fan output. Normal Fan speed is 300..3000 RPM. If a faulty fan is found, It could be changed to identical. If there is a Controller fan output trouble, please contact the Manufacturer. |
¶ F322 |
All fans fault |
Reset controller in STANDBY mode via Commands menu or shut down Device and de-energize all PSUs. If this problem repeats, check Normal Fan speed is 300..3000 RPM. If a faulty fan is found, It could be changed to identical. If there is a Controller fan output trouble, please contact the Manufacturer. |
¶ F323, F324 |
Any/All pumps fault |
Reset controller in STANDBY mode via Commands menu or shut down the Device and de-energize all PSUs. If this problem repeats, check if the faulty pump is connected to the Controller properly. It is allowed to swap pumps connectors between Controller headers PUMP #1-2 to ensure there is no problem with Controller pump output. Normal Pump speed is 3500..4000 RPM. If a faulty pump is found, It could be changed to identical. If there is a Controller pump output trouble, please contact the Manufacturer. |
¶ F331, F332 |
Ambient temperature is out of allowed range |
Please, measure the ambient temperature to ensure it is in allowed range 3-38°C. If this problem still remains, please contact the Manufacturer. |
¶ F333 |
Liquid overheated |
If cooling liquid is overheating, please make sure all fans are operating normally, inlet liquid (T1) is at least 5°C hotter than outlet liquid (T2), outlet air temperature (T4) is at least 5°C higher than inlet air (T3). Check the level of cooling liquid in the reservoir, refill it if needed. After refilling, place the Device horizontally, let the cooling system operate for a while, then place De- vice vertically, then horizontally again. Refill the tank if liquid level becomes lower, then repeat previous operations. |
¶ F334 |
Motherboard synchronization lost | HL3 (white LED on Controller near the synchronization header X2) should be ON when the motherboard is turned on. If HL3 state doesn’t change during motherboard switching, please check if synchronization cable is correctly connected to controller and motherboard (JFP1) headers. |
¶ F335 |
Controller overheating | Normally STM operates at 40-50°C (depends on ambient temperature). If Controller is overheating, it should be changed, please contact the Manufacturer. |
¶ F336 |
+12V power source lost or out of range | Please check the PSU#2, which is connected to the Controller via 24pin cable. If cable is connected securely, try to swap this PSU with PSU#1 (it powers Motherboard). |
¶ Loud mechanical noise |
Pumps operate without liquid. | Pumps operation is not allowed without cooling liquid. It may cause pump permanent fault. Please check the level of cooling liquid in the glass tank, refill it if needed. After refilling, place the Device horizontally, let the cooling system operate for a while, then place Device vertically, then horizontally again. Refill the tank if liquid level becomes lower, then repeat previous operations (if noise hasn’t dissappeared, please, contact the Manufacturer). |
