By using an analogue sensor, two adjustable alarm limits can be used, one for warning (“B”-
alarm) and one for pump stop (“A”-alarm).
3.6.4 Pump memory
The pump memory is located inside the junction box of the pump. The memory is loaded
with data from the factory, which is then uploaded to the MAS system at first start-up.
The data that is uploaded contains the following features:
•
Data plate information
• Sensor types and alarm settings recommended by the manufacturer
• Operational data and data to support service:
– Histograms of temperatures, vibrations, and cycle length
– Start and stop registration
– Service log with a maximum of 200 lines of text
– Conditions to prompt for service based on for example, running time, number of starts
and stops or specific dates
For more information, see the MAS 711 Installation and User Manual.
