holthausen Electronic Vibration monitoring Unit elektronik GmbH ® -small-Compact Setting instructions The following points apply for devices with optional “self-test on starting”: After applying the operating voltage the device starts a complete function test. The green LED3 flashes during the function test (see 18.3). After the function test the relays switches - the switching contacts are closed thereafter. -
Page 11: Analog Output Settings
holthausen Electronic Vibration monitoring Unit elektronik GmbH -small-Compact ® 13. Analog output settings The 0 to 20mA output can be used for displaying of several values on the analog output. With the standard setting (S2=OFF) the output current corresponds to the measured signal. For example, an analog current value of 20mA corresponds to a measured vibration velocity that has reached 100% of the measuring range set. -
