Higher Level
System
This communication port is dedicated for communication with a higher level system,
meaning for instance a Flygt APP/FMC pump controller or a PLC (Programmable Logical
Controller). The base unit acts as a slave in such a network.
A separate document (MAS Base unit, Modbus protocol) de
fi
nes in detail how to set up
the communication with the base unit and contains registers used for reading parameters.
Relay Module
MAS relay module (MRM 01) is an optional part of the monitoring system. One or more
relay modules (maximum number of 8 modules) can be connected to the base unit through
RS-485 Modbus. This will enable MAS to communicate individual alarms on the separate
monitoring channels (A and/or B alarms) to relays and LEDs on the relay module(s).
The pump sensors will be connected to the base unit and the base unit will monitor the
pump and detect unhealthy conditions. The individual alarms will be transmitted to LEDs
and relays on the MRM 01. The con
fi
guration of what alarm that will trigger which relay
on which module is done through the web tool. Sensor con
fi
guration, alarm limits and
additional settings are also done in the web tool. See MRM 01, Installation and User
Manual for more information about setup and connection.
Ingress
Protection
The base unit ingress protection is IP20, which means there is no protection against water.
Therefore, it should be mounted inside an electrical cabinet. The operator panel front has
an ingress protection of 65, which means it withstands a water splash or jet if mounted in a
panel or a cabinet door. The back of the operator panel is IP20.
