Description
Increasingly higher demands are being placed on safety and
system availability – across all sectors. Processes are
becoming more and more complex, not only in mechanical
engineering and the chemical industry, but also in plant and
automation technology. Demands on power engineering are
also increasing constantly.

Adjustable threshold values
Adjustable response delay
Power supply via power module can be selected
Error-free and therefore cost-effective operation can only be
achieved through continuous monitoring of important network
and system parameters. Electronic monitoring relays in the
EMD series are available for a wide range of monitoring tasks
to avoid the consequences of errors or to keep them within
limits.
The operating states are indicated using colored LEDs, errors
that may occur can be sent to a control system 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.

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.

Diagnostics
The LEDs indicate the following error states:
"U" LED (Green)
–
LED ON: Supply voltage present
"MIN" and "MAX" LEDs (Red)
–
–
–
LED flashes: Value outside the window area, set delay time is running
LED ON: Value outside the window area, delay time has elapsed
Both LEDs flash alternately: Lower set threshold value is greater than upper threshold value
"REL" LED (Yellow)
–
–
LED ON: Output relay has picked up
LED OFF: Output relay has dropped out

Connection examples
If a mains fault is present when the module is activated, the output relay remains dropped out and the LED for
the corresponding threshold value lights up.

DELAY
101747_en_04
< DELAY DELAY
Output relay "R" picks up (yellow "REL" LED is ON) if the
measured voltage exceeds the value set at the "MIN"
controller. If the measured voltage exceeds the value set at
the "MAX" controller, the set response delay ("DELAY") starts
(red "MAX" LED flashes). After the delay time has elapsed
(red "MAX" LED is ON), output relay "R" drops out (yellow
"REL" LED is OFF).
Output relay "R" picks up again (yellow "REL" LED is ON) if
the measured voltage falls below the maximum value again
(red "MAX" LED is OFF). If the measured voltage falls below
the value set at the "MIN" controller, the set response delay
("DELAY") starts (red "MIN" LED flashes). After the delay time
has elapsed (red "MIN" LED is ON), output relay "R" drops out
(yellow "REL" LED is OFF).
The "MIN" and "MAX" LEDs flash alternately if the minimum
value selected for the measured voltage is greater than the
maximum value.
