This module is monitoring the pressures of the cooling water cycle in the lab E002. 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.

Sender:	LabWatch-156 / Room E002
Subject :	RL pressure too low / E002 Apaco-Station
	RL= <ist_wert> Water pressure in room E002 of the return line is lower than <soll_wert> bar Water should be refilled soon. {timestamp} More information: https://labwatch.physik.unibas.ch/labwatch/156
Alarm Clear Subject :	RL-pressure Cleared / E002 Apaco-Station
	Water pressure in room E002 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-156 / Room E002
Subject :	FL-pressure too low / E002 Apaco-Station
	Water pressure in room E002 of the flow line drops below 4.5 bar Possible cause: pump failure. {timestamp} https://labwatch.physik.unibas.ch/labwatch/156
Alarm Clear Subject :	FL-pressure Cleared / E002 Apaco-Station
	Water pressure in room E002 of the flow line exceeded 4.5 bar and is in the normal range again. {timestamp}

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.

Subject :	Alarm / E002 Apaco-Station
	Alarm / E002 Apaco-Station {timestamp} Water pressure of return line in room E002 is lower than <soll_wert> bar Below 0.6 bar, the cooling water unit will be shut down. https://labwatch.physik.unibas.ch/labwatch/156

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
