Part C Special applications, functional checks, service, and order numbers Sect. 8.28.2 Retrofitting of magnetic sensors MP (optional)Switch off the power supply before opening the housing.1) Remove the cover from the terminal compartment (remove 2 screws).2) Pull all cables out of the plug-in terminals.3) Remove the glass cover from the control compartment (remove 4 screws).4) Remove 4 screws from the front panel F, take hold of the handle on the upper end of thefront panel and carefully pull the complete electronic unit out of the signal converter housing.5) Put down the electronic unit with the front panel F facing down (see illustration on the nextbut one page).6) Position the 2 mm (0.08”) thick insulating strip (Order No. 3 15940.01) loosely on top of theMP printed circuit board (PCB). The magnetic sensors and chip capacitor slip into the 4holes in the insulating strip. Slip the MP PCB and insulating strip from right to left betweenthe front panel and BDE PCB, taking care that the MP PCB and insulating strip are slippedthrough the three retaining clips H at the back of front panel F. Slip the socket connector ofthe MP PCB onto the (5-pin) plug connector PL MP .7) Fix the MP PCB with special steel tooth lock washer and nut S MP to establish contactbetween the back of the PCB and the back of the front panel. When correctly fitted, the MPPCB must be slightly bent between the final retaining clip H and the plug connector PL MP .8) Re-assemble in reverse order (items 4 to 1 above).9) Switch on the power supply. The ”magnet active” LED on the front panel is green.The function of the corresponding keys is tripped by touching the glass pane above the3 white fields ”→, ↵ and ↑” with the bar magnet. The LED lights up red, see Section 4.2,items and .05/2003 IFC 110 F 81
