Page 11: Installation And Removal
User Guide Landmark Basic Signal Processor Installation and Removal 3.1 Fitting the unit onto a DIN rail The Landmark Basic (LMB) processor is designed to be mounted on a stand- ard DIN rail. To install the unit. Ensure that a suitable DIN rail (DIN EN 50 022) is available and installed correctly (refer to Appendix). Refer to Fig. 3. Rest the uppermost groove on the rear of the processor on the top lip of the DIN rail. Push the bottom of the unit so that the sliding spring catch clips onto the DIN rail. 3.2 Removing the unit from a DIN rail Refer to Fig. 4. Insert a screwdriver into the sliding spring catch via the slot on the underside of the unit. - Page 12 Landmark Basic User Guide Signal Processor 2 core screeened cable Pigtails max length = 30mm Screen Peak Picker Twisted pair reset Signal o/p + Processor supply Signal o/p - N o n - G r e y n e s s E m is s iv it y 11 12 13 14 15 16 Live...

Page 15: Using The Processor
User Guide Landmark Basic Signal Processor Using the Processor 4.1 Location of controls The processor has controls for adjusting Averager response, Peak Picker decay rate and Emissivity/Non-Greyness value. The controls are on the front panel of the processor. See Fig. 6. 4.2 Functional Block Diagram A functional block diagram of the Landmark Basic processor is given in Fig. -
Page 16: Peak Picker
Landmark Basic User Guide Signal Processor 4.5 Peak Picker Note The averager function precedes the peak picker function on the proc- essor signal path. The input to the peak picker will therefore be an averaged signal. This can cause the output of the processor to appear to be in error, particularly with a large averager response time and a small peak picker decay time. -
Page 17: Emissivity/Non-Greyness Setting
User Guide Landmark Basic Signal Processor 4.6 Emissivity/Non-Greyness setting The required emissivity/non-greyness correction can be set by setting the Emissivity/Non-Greyness knob (see Fig. 6) to the required setting on the rel- evant scale. To enable precision setting of the emissivity/non-greyness output, a voltage output, proportional to the set value of emissivity/non-greyness, is available between terminal 14 and 15 of the processor. -
