For the StartUp Timer, you only have to set the Preset high enough, longer than the last (farthest upstream) conveyor startup time, and for the ShutDown Timer, longer than the first (farthest downstream) conveyor shutdown time. Then you should use comparison instructions to do the individual conveyor startups and shutdowns.

Static Start of a Fully Loaded Conveyor bulkonline Forums

Nov 05, 2005 · Can anyone advise me as to what the standard design practice is to handle starting a fully loaded conveyor? The designer has advised me that the CEMA guidelines do not make allowances for static starts and only use dynamic resistance when it comes to sizing drive motors and the additional torque/power required for startup is taken up in the service factor of the motor.
