User Manual
First two outputs are for analog signals and the third output is for a digital
signal.
The buffered analog signal is divided by 2.
The measuring instrument connected to these buffered outputs must
compensate for this. This can be done by using a sensitivity that is 50% of the
connected sensor. For example, if the sensor is 100 mV/g, then set the
sensitivity on the measuring instrument to 50 mV/g.
The buffered analog outputs are maximum ±11 V and cutoff frequency (-3
dB) is at 60 kHz.
The buffered digital outputs are 5 V TTL signal.
Protection Part Configuration
RS485 Modbus
Each protection module has 2 separate RS485 Modbus connections L1 and L2 for
redundant operation.
The physical locations of RS485 connection L1 and L2 are found in the back of CMM +
PRM slot as shown in
The connection diagram is found in
RS485, Relay Outputs, Rack Disarm
The RS485 Modbus for protection module shall only be terminated at the end(s) of the
bus. At each protection module, termination of 120
can be manually activated by DIP
switch as shown in the table below.
