- Page 4 2.1: Mounting and Access Before mounting the LDX-D, please refer to section 2.10. Hook the LDX-D on the DIN rail with the release clip facing down and push onto the rail until a ‘click’ is heard. To remove, use a screwdriver to lever the release clip down. Pull the bottom of the housing away from the rail and unhook.

- Page 6 Link ON Link PARKED 2.4: Primary Frequency The LDX-D primary frequency is set using links as shown below. Transducer specifications determine the optimum frequency. Primary amplitude is not adjustable. The DRC uses ratiometric techniques and is insensitive to primary amplitude. Maximum secondary transducer amplitudes must be observed.

100 kΩ - link PARKED 2 kΩ - link ON 2.6: Bandwidth The LDX-D has selectable bandwidth (BW). The bandwidth setting is independent of other DRC settings. Where possible, the lowest bandwidth setting should be used to minimize output noise. 500 Hz - Link ON 1 kHz - Link PARKED Note: Total system bandwidth is dependent on probe type and application. -

Vout. Iout This is a current output only, LDX-D is not loop powered. This can be set for up to ±20 mA. A common output is 4-20 mA. The Iout is proportional to Vout but cannot be independently adjusted. The approximate relationship... -

Black Transducer body ground The CT terminal is provided to terminate the center tap (CT) connection of a trans- ducer if present. There is no electrical connection within the LDX-D. This is provided to allow for quadrature components to be fitted if required. 2.10: Placement and EMC LDX-D has been designed to comply with EMC regulations. For best performance, the EMC compliance of surrounding equipment must be considered. - Page 10 LDX-D, then noise may be introduced. All 0 V terminals on LDX-D are connected internally. Ground 2 may be connected to any of the LDX-D 0 V terminals, however terminal 11 is preferred. Screen ground (ground 1) may be connected via terminal 11.
- Page 11 Mout# (GND) 2.11: LDX-D Synchronization When a system comprises several LDX-D modules, it is possible to synchronise primary oscillator phases. Synchronization will not be required for most installations. It is only required when transducers and their cables are installed in close proximity to each other and there may be electrical interaction or cross- talk between probes.
- Page 12 If the transducer is known to be outside the standard sensitivity range, the X1, X2, X5 or DIV2 links will have to be used. Please refer to section 5.1 Step 2 - Align LDX-D and transducer null Any electrical offset in the LDX-D is removed. The transducer position is adjusted so that transducer and LDX-D nulls are aligned.
- Page 13 Example: ±10 V is required from a ±1 mm transducer. Set the transducer at the +1 mm position and set the output to +10 V. Step 4 - Setting uni-polar full scale output (adding an offset) Move the transducer to the null position. LDX-D output will be 0 V or 0 mA Apply offset using the +VE, -VE, 5V and 10 V links and adjust the fine offset ontrol to set precisely. Both links may be used to give greater offset shift.
- Page 14 By linking two LDX-D modules, the following analog arithmetic may be performed: A+B, A-B, (A+B)/2 and (A-B)/2. The output of LDX-D A, Vout A , is connected to the Min terminal of LDX-D B. The output of LDX-D B is routed internally to the arithmetic circuits and the result is available at the Mout terminal.

Example: ±10 V required for A-B. If each LDX-D is set to ±10 V, then A-B would calculate to be ±20 V. However, as this is not possible, each LDX-D must be set to ±5 V or use ±10 V (A-B)/2. - Page 16 IN 120 – 230 VAC output output AUTO Mout# Mout# G uar d power power Mains in LDX-D A linked to LDX-D B LDX-D A LDX-D B 7.0: Specification 7.1: Mechanical Outline (mm) 111.0 22.5 LDX-D Solartron Metrology Ltd. www.solartronmetrology.com Bognor Regis PO22 9ST sales@solartronmetrology.com...

When a non-standardised (unplugged) Half Bridge transducer is con- nected to LDX-D set for 2 kW, transducer characteristics will be similar to the stand- ardised (plugged) version of that transducer. Any difference in transducer sensitivity is removed during LDX-D set-up.
