EVS-2 Characteristics and Orientation
To prevent damage to the EVS-2 vibration switch, the following vibrations may not be
exceeded:
 Vibration 15 g
 Shock 150 g
Two-Channel LED Indicators
Two independent, adjustable level detectors with selectable delay times are equipped with
corresponding relays which are typically used for Alarm and Shutdown. Both channels use the
same vibration range selection.
Red and Yellow LED indicators representing these two channels are illuminated during normal
use. When a fault is activated, the LED indicators will turn off.
IMPORTANT! Because the EVS-2 resets automatically when the
vibration level returns below the set point, it is important to ensure
that the fault has been addressed before restarting the equipment.
