Features
Active power detection in 1 and 3-phase networks
2 threshold values, can be set separately
Adjustable starting override
Adjustable response delay
Error memory (optional)
Temperature monitoring of the motor winding
Power supply can be selected with power module
Detecting switched off loads

Requirements pertaining to safety and system availability
increase constantly – regardless of the industry. Processes
are becoming more and more complex, not only in the
mechanical engineering and chemical industry but also in
system and automation technology. Demands on power
engineering are also constantly on the rise.

–
Error-free and therefore cost-effective operation can only be
achieved through continuous monitoring of important network –
and system parameters. The electronic monitoring relays of –
the EMD series are available for various monitoring tasks.
–
The operating states are indicated using colored LEDs, errors –
that may occur can be sent to a controller via a floating
contact or can shut down a part of the system. Some device
versions are equipped with startup and response delays in
order to briefly tolerate measured values outside the set
monitoring range.
WARNING: Risk of electric shock
Never carry out work when voltage is present.
Make sure you always use the latest documentation.

Power supply
The power module for power supply is supplied in a transport casing to prevent the connection legs from being bent.
To install the power module in the relay housing, remove the transport casing and position the power module in the recess
in the side of the housing (ensure that it is the right way round). The red locking latches snap in with an audible click when
the power module is securely positioned.
To remove the power module, press the two red locking latches together and pull out the power module.
The power module is not supplied as standard.

Installation
WARNING: Risk of electric shock
Never carry out work when voltage is present.
The module can be snapped onto all 35 mm DIN rails according to EN 60715.
