This module is monitoring the pressures of the cooling water cycle in the lab O306. It measures the pressure in the flow line (german: “Vorlauf”, VL) and the return line (german: “Rücklauf”, RL) and calculates the difference.
If the return line pressure falls below 0.6 bar, the Apaco station will shut down. To avoid this situation, a warning message is sent to techalarm-phys@unibas.ch by email if the RL is lower than 1.03 bar. From this email account, the email is forwarded to the responsible staff.
| Sender: | LabWatch-162 / Room O306 |
| Subject : | RL pressure too low / O306 Apaco-Station |
| RL= <ist_wert> Water pressure in room O306 of the return line is lower than <soll_wert> bar Water should be refilled soon. {timestamp} More information: https://labwatch.physik.unibas.ch/labwatch/162 |
|
| Alarm Clear Subject : | RL-pressure Cleared / O306 Apaco-Station |
| Water pressure in room O306 of the return line exceeded bar and is in the normal range again. <timestamp> |
If the flow line pressure (VL) drops below 1.55 bar, the pump could have failed. A warning message is sent to techalarm-phys@unibas.ch by email and forwarded to the responsible staff.
| Sender: | LabWatch-162 / Room O306 |
| Subject : | FL-pressure too low / O306 Apaco-Station |
|
Water pressure in room O306 of the flow line drops below 1.55 bar
Possible cause: pump failure. https://labwatch.physik.unibas.ch/labwatch/162 |
|
| Alarm Clear Subject : | FL-pressure Cleared / O306 Apaco-Station |
|
Water pressure in room E002 of the flow line exceeded 1.55 bar and is in the normal range again.
|
If the RL pressure keeps dropping below 0.85 bar, a alarm message is sent to techalarm-phys@unibas.ch by email and forwarded to the responsible staff.
| Sender: | LabWatch-162 / Room O306 |
| Subject : | Alarm / O306 Apaco-Station |
| Alarm / O306 Apaco-Station {timestamp} Water pressure of return line in room O306 is lower than <soll_wert> bar Below 0.6 bar, the cooling water unit will be shut down. https://labwatch.physik.unibas.ch/labwatch/162
|
If the pressure difference is below or above its limits, a warning message is sent to techalarm-phys@unibas.ch by email and forwarded to the responsible staff
| Sender: | LabWatch-162 / Room O306 |
| Subject : | Alarm / O306 Apaco-Station |
