2-4 MPCE (Machine Primary Control Element) Monitor
MPCE (Machine Primary Control Element) is the machine's main control element and is used between the
SL-R11 control output (FSD) and the machine to directly control the machine start/stop. The MPCE uses
safety relays, contactors, and so on, and inputting the feedback signal from these to the MPCE monitor input
terminal provided in the SL-R11 makes it possible to monitor MPCE errors. When an MPCE error causes the
FSD and MPCE operation not to be linked, the SL-R11 immediately turns off the FSD, and the SL-C Series
and SL-R11 go to the lockout condition.
