Traditionally, Saia PCD

controllers could only be reliably set to RUN or STOP mode
fromthePG3/4/5.WiththePCD2.M170andPCD2.M480CPUs,itisalsopossibleto
inuencetheoperatingstatewithoneoftheswitchesaccessibleonthefront.
OnthePCD2.M170,theswitchislabelledRun/Halt;onthePCD2.M480,itislabelled
Run/Stop, in keeping with the practice for xx7 CPUs.
Withbothcontrollers,switchingtoSTOP/HALTcausesachangefromRUNtoHALT
mode; switching to RUN causes a cold start to be executed.
Asdeliveredfromthefactory,theRun/StoporRun/Haltswitchisdeactivated;itcan
be activated with a jumper located right next to the switch:
