24.2- OPERATING OF THE "PO" (PRESENT ORDER) IN T70/1 and T70/2 PROPORTIONAL TRANSMITERS
Maintenance / Service
In the mechanisms block where the PO signals are generated as an OR function –using several diodes- with all
the digital input signals coming from the pushbuttons and the auxiliary inputs.
This PO signa lis used for the Present Order Circuitry" for secure and axternal auxiliary functions from the
microprocessor.
If it is required to remove the PO signals associated to digital maneuvers of the pushbuttons (M1, M3, M5, M7,
Dor the M23-M26 maneuvers the D3 diode must be removed from the PCB and for the M27-M30 maneuvers
the D6 diode must also be removed from the PCB
