Example: Full Scale 0.00 – 1.00 IPS, Frequency Band 10 – 1000 Hz At 0 .00 IPS, 4 mA flows from the transmitter to the controller . At 0 .50 IPS,  12 m flows from the transmitter to the controller . At 1 .00 IPS, 20 mA flows from the transmitter to the controller . The monitoring channel provides two relay outputs . The system comes from the factory with a specific vibration range in IPS or mm/s . This range must be known to configure the relay set points . It is recommended that baseline and typical alarm values of vibration are also known before setup is attempted . The relays provided by the internal controller are highly configurable . Refer to the PD765 user manual for detailed programming instructions . All of the following parameters can be adjusted: • Relay Action – Automatic, Latching, Auto + Manual Reset, Latch with Clear • Relay Operation – Set and Reset points (Hysteresis), On and Off time Delays

Example Setup 1: A full-scale range of 0 .00 – 1 .00 IPS has been specified . The baseline vibration on the machine to be monitored is 0 .18 IPS-pk . Alarm and shutdown levels of vibration are defined as 0 .35 IPS-pk and 0 .65 IPS-pk, respectively . Reset points are specified as 0 .30 IPS-pk and 0 .60 IPS-pk . Using the provided PD765 Process Controller manual, select the relay operation and action desired . For this example, we will have LOC, Latching Operation with Clear relays . Then program “Set 1” as 0 .35 and “Set 2” as 0 .65, then program reset points, “rST 1” as 0 .30 and “rST 2” as 0 .60 . After relays have been programmed, scaling must be set . For this example, we will use a 4 - 20 mA input with a 0 .00 - 1 .00 IPS display . Program “inP1” as 4 .00, then “diS1” as 0 .00, then “inP2” as 20 .00, then “diS2” as 1 .00 . This will create an input of 4 mA, display of 0 .00 IPS, and at an input of 20 mA,  1 .00 IPS will be displayed by the meter . The system will now actuate the LOC Relay (Relay 1) when the vibration level reaches 0 .35 IPS-pk and another  13LOC Relay (Relay 2) when the vibration 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 .
