Page 15: Configuring Relays
Configuring Relays The input to the internal controller comes from the vibration transmitter . They are built with a specific full-scale range and frequency band . The full-scale range of the transmitters must be known for the controllers to display the correct vibration value . - Page 16 level reaches 0 .65 IPS-pk . To reset the LOC relays, the vibration level must fall below the reset point of 0 .60, then press the ACK for relay two . Once the vibration level falls below 0 .30, press the ACK to reset relay 1 . Analog Output The analog 4-20mA signal represents the amount of vibration energy present at each channel based on the internal transmitter’s full scale, i .
