Cables used to connect the PI S334 to the BCU. Each piezo head has 5 cables terminated with LEMO connectors: 3 for the HV commands (Axis 1, Axis 2, 100V) and 2 for the strain gauges (Axis1 and Axis2). The 5 cables of each piezo head are connected to 5 pass-through connectors installed on the ConnectorPanel of the LGSW unit. From the ConnectorPanel a 6-m long, 5-cables bundle goes to the BCU. The bundle is protected with a plastic wrinkling-tube.

Panel connectors are LEMO ABD.00.250.NTM (for the HV signals) and SWH.0S.304.CLLPV (for the strain gauges)

Installation and maintenance

The end with 5 LEMO connectors goes to the BCU. The end with 3 BNC and 2 LEMO connectors goes to the ConnectorPanel. The ConnectorPanel is color coded: if, for instance, you are installing the cabling for the BlueChannel, you should connect the cable to the 5 connectors encircled by the blue line. Pay close attention to not mix the axis!

On the BCU side

The BlueChannel is connected to the HVC board closer Actuators and Sensors are numbered from 0 to 6. Connect actuators to 0,1,2 or to 3,4,5 accordingly to the label. Connect sensor to 0,1 or to 3,4 accordingly o the label o
