Page 4: General Information
Proper use The LEAKGUARD BASIC district heating monitoring device is designed for measuring insulation and loop resistance to detect leaks in pipe systems. For configuration, the device can be connected to a PC (laptop) via the Ethernet interface.
Page 5: Safety Instructions
• Do not make any changes to the device. • Assembly, maintenance and repair work may only be carried out by trained staff. • Only use original BRUGG spare parts. CAUTION! Observe handling instructions . Electrostatically sensitive components .
Page 6: Installation
Page 6 Installation Mounting The LEAKGUARD BASIC is situated in a wall-mounted housing and is attached to the wall with three screws. After assembly, the screw heads must be sealed with the enclosed rubber seals. Detailed assembly and installation instructions can be found in the separately enclosed installation instructions of the housing manufacturer.
Page 7: Function/Commissioning
Page 7 Function/Commissioning The LEAKGUARD BASIC is a measurement and monitoring device for insulation and loop resistance for detecting leaks in pipe systems and interruptions of the measurement loop. Each device can cyclically monitor two measurement loops, e.g. the flow and return of a district heating pipe.
Page 8: Commissioning
Page 8 Commissioning After switching on the supply voltage, the LEAKGUARD BASIC is initialised and runs a self-test. All LEDs light up, then the LEDs of the bar displays go out from top to bottom. The LEAKGUARD BASIC automatically starts continuous measurements.
Page 9: Acknowledging Alarm
Page 9 Alarm acknowledgement To cancel remote alarms although a ISO bar display LED measured value is still in an alarm state, Loop “error” LED ISO “error” LED alarms can be acknowledged in the device. To do so, press the acknowledgement button located to the right of the red LED.

Page 14: History Menu Item
Page 14 History menu item The LEAKGUARD BASIC stores the current measured values once a day, 24 hours after the last measurement. The list contains a maximum of 30 entries, with the most recent entry at the top. If the number of entries exceeds the maximum of 30, the oldest entry is over- written.
Page 15 Page 15 The "Graphic" button above the table must be pressed and the desired meas- urement channel selected for this purpose. Clicking the "Table" button causes the display to return to tabular view.
