This module is monitoring the pressures of the cooling water cycle in the lab U107. 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 1.1 bar. From this email account, the email is forwarded to the responsible staff.

| Subject : | RL pressure too low / U107 Apaco-Station |
| RL= <ist_wert> Water pressure in room U107 of the return line is lower than <soll_wert> bar Water should be refilled soon. {timestamp} More information: https://labwatch.physik.unibas.ch/labwatch/157 |

| Alarm Clear Subject : | RL-pressure Cleared / U107 Apaco-Station |
| Water pressure in room U107 of the return line exceeded bar and is in the normal range again. <timestamp> |
If the flow line pressure (VL) drops below 4.5 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-157 / Room U107 |
| Subject : | FL-pressure too low / U107 Apaco-Station |
|
Water pressure in room U107 of the flow line drops below 4.5 bar
Possible cause: pump failure. https://labwatch.physik.unibas.ch/labwatch/157 |
|
| Alarm Clear Subject : | FL-pressure Cleared / U107 Apaco-Station |
|
Water pressure in room E002 of the flow line exceeded 4.5 bar and is in the normal range again.
|
If the RL pressure keeps dropping below 0.8 bar, both an acoustic and an optical alarm will be triggered. The alarm can be silenced for an interval of 60 minutes. The same action will take effect if the pressure difference goes below or above its limits. An alarm message is sent to techalarm-phys@unibas.ch by email and forwarded to the responsible staff.
