Undertemperature Interlock
The undertemperature interlock prevents the melter motors from being
switched on as long as the material is too cold and thus too thick. This could
damage the pumps.
The undertemperature interlock is active during every
Heatup phase
(status
display) and after every standby. Also refer to section
Troubleshooting,
Undertemperature Fault Triggered.
If the system ready delay time is
activated, this time must also have expired before the interlock is disabled.
Motor Startup Protection
The motor startup protection prevents the motors from starting up on their
own after heatup or after a fault. The melter goes to startup protection if at
least one motor was running before heatup or before the fault occurred.
