Max Rate Sp Delay; Min Rate Sp Delay; Max Speed Setpoint; Min Speed Setpoint - MERRICK Genetix Safety, Installation, Operation And Maintenance Manual

Max Rate SP Delay

This value provides a delay for the High Rate Setpoint limit, in order to prevent
nuisance alarms. The feedrate setpoint must remain above the limit value for
duration as long as this delay value for the logical output to be set. This delay
value is set in seconds.

Min Rate SP Delay

This value provides a delay for the Low Rate Setpoint limit, in order to prevent
nuisance alarms. The feedrate setpoint must remain below the limit value for
duration as long as this delay value for the logical output to be set. This delay
value is set in seconds.

Max Speed Setpoint

This is the maximum allowed speed setpoint, and the logical output "High
Setpoint" will be set if it is exceeded for longer than the duration set by the limit
"Max Speed SP Delay" (see below). This limit is set in units of speed.
Note also that if setpoint clamping is enabled (see Main Menu > Advanced
Setup > Feeder Control > Settings), the setpoint used by the controller will be
clamped to this limit value even if it exceeded. However, in this case the logical
output "High Setpoint" will still be set.

Min Speed Setpoint

This is the minimum allowed setpoint, and the logical output "Low Setpoint" will
be set if the setpoint drops below this limit for longer than the duration set by
the limit "Min SpeedSP Delay" (see below). This limit is set in units of speed.
Note also that if setpoint clamping is enabled (see Main Menu > Advanced
Setup > Feeder Control > Settings), the setpoint used by the controller will be
clamped to this limit value even if it drops below. However, in this case the
logical output "Low Setpoint" will still be set.
Note this limit is only active under the following conditions:
Feeder Control is enabled (see Main Menu > Advanced Setup >
•
Configuration > Feeder Control) and the belt is commanded to run.
Feeder control is not enabled and the logical input "Belt Running" is on.
•
No calibration routine is running.
•
Note that the Max and Min Speed Setpoint limits are active only if the Feeder
Control Method is set to "Speed Control" (see Main Menu > Advanced Setup >
Feeder Control > Method)
Max Speed SP Delay
This value provides a delay for the High Speed Setpoint limit, in order to
prevent nuisance alarms. The Speed setpoint must remain above the limit value
for duration as long as this delay value for the logical output to be set. This
delay value is set in seconds.
Min Speed SP Delay
This value provides a delay for the Low Speed Setpoint limit, in order to prevent
nuisance alarms. The Speed setpoint must remain below the limit value for
