Page 7: Operating Mode Description
OPERATING MODE DESCRIPTION This unit monitors continuously the cooling water flow and cooling temperature of any critical laboratory equipment operating without surveillance and helps preventing damages caused by unsufficiant cooling action. It can easily be mounted on already existing installations. Cooling water admission is controlled by an solenoid valve fitted onto a normal water tap. - Page 8 OPERATING MODE DESCRIPTION During normal operation, AQUASTOP II works in surveillance mode. The actual temperature of the ® cooling water is shown in the upper part of the display. If an external temperature sensor is used (which automatically disconnects the internal temperature gauge in the flow sensor), make sure that this sensor is located at an appropriate position to measure the critical temperature in the process.

Page 9: Installation And Wiring
INSTALLATION AND WIRING 5.1 Installation The installation site must provide easy access for the operator without hazard. Sufficient mechanical stability must be guaranteed, also secure the device from slipping on the installation surface. To ease operation and good visibility of the display, the handle can be used as a support. To adjust the position of the handle, unfasten the screws on both sides of the handle and fasten them again after adjustment. - Page 10 INSTALLATION AND WIRING 5.3 Wiring of accessories Fig.: Back AQUASTOP ® External Pt100 temperature Flowmeter Floating alarm contact max. 230 V / 1 A Serial interface RS-232 Fuse heating 16 A MT Fuse solenoid valve 0,5 A MT Fuse controller 0,2 A MT Power cord Socket solenoid valve 230 V 10 Socket heating 230 V, 16 A...
