I/O and Safety String Checkout
(continued)
• SAFE, CDCF, CDCR, CST and all interlock inputs (port 3) must be active with no critical
controller faults in order for SAFSPM, SAFCPU, SAFCPM, and TSRCPU to be active.
• Any optional I/O present in the job software must be in the indicated state for the
Correct I/O Pattern column.
• MCC2, MCC2M = Only seen on jobs with electronic or Wye-Delta (2 contactor) starting.
• MUTS, MCF = Only seen on jobs with electronic starting.
• MCE, MCD = Only seen on jobs with across-the-line (1 contactor) starting.
• PRSW = Only seen on jobs equipped with a low pressure switch.
• OLTS, OLTO = Only seen on jobs equipped with viscosity control thermostats.
• INHA, INHAM = Only seen on jobs with hoistway access.
• Bit Patterns provided are for jobs with electronic starting and hoistway access.
• I/O locations marked with an X are either unassigned or have a signal assigned whose
status is unimportant at this point. If required, refer to the job’s Car I/O Assignment
Sheet.
