• the current paths will be open when the measured value is lower than Fuh (in this case 950 rpm). INITIALISATION Directly after power on, the SV MR0 U carries out an initialisation comprising a complete self-test. After approx. 3 s the SV MR0 U is ready for operation. -
Page 8: Installation
SAFETY SPEED MONITOR SV MR0 U INSTALLATION Mechanical installation of the device Mount the device on a DIN rail in a housing protected against dust and humidity (min. IP 54). Leave enough space between the unit and the top and bottom of the housing to enable air circulation and to avoid excessive heating. -

Page 11: Set Up Of The Device
After the first power on of the device it is necessary to configure the Underspeed Frequency (Fu) using the three decade switches located in front of SV MR0 U. The switches allow the user to enter the value of the desired preset frequency (as described below). - Page 12 SAFETY SPEED MONITOR SV MR0 U SWITCH OPERATION / RESULT Start of configuration: Set the 3 switches to configuration position 0/P Switch on the power supply of the device > The LED CONF is blinking Adjust Potentiometer P1 from the position 0/P to the needed Value >...
- Page 13 SAFETY SPEED MONITOR SV MR0 U Examples The switch point value can only be set when operating voltage is connected to the device and the three switches are set as indicated (factory setting). Figure 1 Factory setting Set P1, P2 and P3 to obtain the switch point value. Examples:...

Page 14: Automatic/Manual Mode Selections
SAFETY SPEED MONITOR SV MR0 U AUTOMATIC/MANUAL MODE SELECTIONS The selection of the operative mode between Automatic or Manual is made by two input terminals 4 and 5. In figures below the two possible selections are showed. Figure 4 - Manual mode selection Figure 5 - Automatic mode selection 8541100 - 14/10/2022 - Rev.3... - Page 15 SAFETY SPEED MONITOR SV MR0 U Automatic mode With Automatic Mode selected, just after the power up, a 10 seconds timer automatically starts and during all these 10 seconds the output relays are closed. This permits to the motor connected to the relays to reach the selected frequency.
- Page 16 SAFETY SPEED MONITOR SV MR0 U The RESTART command must be installed outside the dangerous area in a position where the dangerous area and the entire work area concerned are clearly visible. It must not be possible to reach the control from inside the dangerous area.
