Jog Ok While Blocking; Discharge Monitor; Mob Off Delay - MERRICK Genetix Safety, Installation, Operation And Maintenance Manual

Blocking
This is a switch (Y/N) that indicates whether or not it is okay to run the belt
forward in Manual mode, while the MOB is indicating that there is material on
the belt. If "Blocking" is enabled ("Y"), then this is not allowed. This is a
requirement of the NFPA for some coal feeders.

Jog OK while Blocking

This is a switch (Y/N) that indicates whether or not it is okay to jog the belt
forward while "Blocking" is enabled (see above). If this seting is turned on
("Y"), and blocking is also enabled, then it will still be possible to jog the belt
forward (see Main Menu > Feeder Control) while the MOB is indicating that
there is material on the belt.
Numeric Data
The following numeric parameters can be set for the Material on Belt Switch:

MOB Off Delay

MOB Off Delay
This parameter sets the time, in seconds, that the controller will ignore a
loss of material on the belt, before taking any action. This can be used to
prevent temporary loss of material from un-necessarily causing alarm
(nuisance trips).
