5.16 Gap Control Rot.
The function is only valid and shown in a BRM-DM2.
GCR Work mode
Work mode, 0 = disconnected, 1 = for Valmet single disc, 2 = for Valmet CD-
refiner.
GCR Interval
Interval between each gap control (s).
GCR Deadband
Value for dead-band, plus and minus relative the set limit.
GCR Gain
Span (%).
GCR Filter
Filter time (s). Maximized to half of the set interval.
GCR Ov.al.limit
Over alarm limit (mm). Over alarm checks the balance of gap controls together and
apart. In case of unbalance and the together movement is considerably higher than
apart movement, an alarm occurs to prevent a segment clash. The parameter sets the
limit of this unbalance distance.
GCR Ov.al.speed
Count down speed for over alarm (mm/min).
GCR Und.al.limit
Under alarm limit. Under alarm means that the dead band is not passed or reached in
a set number of gap controls. This means that the rotor travel does not match the step
motor activations due to an error.
GCR Controlspeed
Rotor movement speed (mm/s). Set normally to 0.05 for a Valmet SD-refiner. For a
CD-refiner the parameter must match movement speed of the stator, typically 0.03
mm/s.
5.17 Gap Control Sta.
The function is only valid and shown in a BRM-DM2. These parameters are not used in a Valmet SD-refiner.
GCS Deadband
Value for dead-band, plus and minus relative the set limit.
GCS Gain
Span (%).
GCS Filter
Filter time (s). Maximized to half of the set interval.
GCS Ov.al.limit
Same as the
GCR Ov.al.limit
above.
GCS Ov.al.speed
Same as the
GCR Ov.al.speed
above.
GCS Und.al.limit
Same as the
GCR Und.al.limit
above.
5.18 Gap Guard
The function is only valid and shown in a BRM-DM2.
GGD Limit rotor
The limit is the allowed gap value below the set point before a GapGuard is released.
GGD Gain rotor.
Sets the gain of the GapGuard movement. The movement can be over-compensated
(> 100%) or under compensated (<100%).
GGD Limit stator.
As
GGD Limit rotor
but for the stator in a CD-refiner.
GGD Gain stator
As
GGD Gain rotor
but for the stator in a CD-refiner.
5.19 Digital in/out
DIO Input=
Status for the digital inputs, hexadecimal indication: 01 = input 1 active, 02 = input 2
active, 03 = input 1 and 2 active, and so on, 80 = input 8 active.
DIO Out Status
Status for digital outputs, hexadecimal indication: 01 = output 1 active, 02 = output 2
active, 03 = output 1 and 2 active, and so on, 80 = output 8 active.
DIO In Config.
Set configuration for the digital inputs.
DIO Out Config.
Set configuration for the digital outputs.
5.20 AGS Interface
The function is only valid and shown in a BRM-DM2.
AGS Off/TDC/AGS
0 = no gap sensor, 1 = TDC-sensor, 2 = AGS-sensor.
