Function 2: (Compressor lockout based on run time hours)
If this option has been enabled, at midnight if any compressor exceeds the number of run hours specified, the
system will disable all compressors (circuits) and change the unit state to MAXIMUM RUN TIME. This test will
only be made a midnight when new day logic is being executed. In this state the Magnum will not enable
normal operations and the only screen that will be available is the Passwords. If the Magnum is reset the
chiller state will be MAXIMUM RUN TIME not UNIT IN POWER UP. Once the system state is MAXIMUM
RUN TIME the system can be accessed from MCS-Connect but the system will not accept changes to the
Relay Output states.
