Siemens SICLOCK PCON Operating Instructions Manual page 13

• Switch 5 can be used to invert the output signal of all electrical outputs.
• The SICLOCK PCON provides the option of monitoring all inputs or the
120 VDC voltage output. For this purpose, a check is made to determine
whether a status change takes place on the signal lines. If a steady signal of
an appropriate length is detected, an alarm contact is activated. Switch 6 can
be used to activate this monitoring function. Switch 7 is used to specify
whether the inputs or the output is to be monitored. Switch 8 can be used to
specify whether the alarm relay switches after 3 seconds or 3 minutes in the
event of a missing signal change.
