Page 7: Preamble
A current output and a voltage output are always available, however, only one signal output variant can be adjusted. Various current and voltage variations are configured via jumpers, for subsequent changes, however, a readjustment is required. The LCV has a control input in order to activate the 100 % control signal in the sensor (if available). Power Supply Mains operation Power supply: 12V to 28VDC, min. -

Page 9: Switching The Device On
5.3.2 Presettings of the Sensitivity By factory default, the LCV is adjustable to approx. 2 mV/V. If the sensitivity of the sensor deviates from this value, the resistance ‘Gain rough’ must be replaced. First, the sensitivity of the sensor must be determined by the data sheet, test certificate, sensor label, etc. and multiply this value by 312. -
Page 10: Adjustment Description
5.4.2 Pre-adjusted LCV as a Board or Kit All sensor cables must be connected to the LCV, use only shielded cables and keep the sensor lines as short as possible. Connect the supply and the pre-adjusted current or voltage output. If the option control signal is available, it can be switched on via a positive control signal or a push-button. -
Page 11: Interfaces And Connections
5.5.3 Control Input, Switch-on Control Signal By the control signal on the LCV, the 100 % control signal in the sensor (if available / see sensor data sheet) can be switched on. The sensor electrically simulates a 100 % value (like 100 % load). Thus, re-adjustment and system control of subsequent evaluation systems is possible, without having to use a highly precise reference weight or torque on the sensor. -
