Need to make contact with someone who can review programming of a DL105 for proper sequencing and/or possible "trojaned " shut-down counter. Applied use is for automatic lighting (120v on-off), gate operation (open-close contacts) and EMI door lock solenoid (24v power on-off) for a circa 1974 residential elevator. Simple sequence from pushbutton and stop switch inputs to specified outputs, but code may be password protected and require clearing of PLC and complete re-write of script. Thanks.
