BRC MENU

REJECT CONFIRM

yes enables reject monitoring. It thus checks whether the contaminated product was successfully rejected.

The status of the metal detector switches to ERROR 4 Reject and ERROR Output is activated in case the input REJECT VALID does not receive a High to Low transition within the time window as set by REJECT CONF ms.

Note: Optional photo sensor and reject pusher required.
Note: reject valid has to be set in IN/OUT MENU

Default: no

REJECT CONF ms

Time window from ‘metal output’ until ‘rejected product interrupted the reject monitor photo sensor’.

The status of the metal detector switches to ERROR 4 Reject and ERROR Output is activated in case the input REJECT VALID does not receive a High to Low transition within the time window as set by REJECT CONF ms.

Note: Optional photo sensor and reject pusher required.
Note: reject valid has to be set in IN/OUT MENU

Range: 20-9980
Default: 2000

BIN FULL

yes enables reject bin monitoring.
It thus checks whether the rejection bin is full.

Note: Optional photo sensor required.
Note: bin full has to be set in IN/OUT MENU

Default: no

LOW AIR

yes enables air pressure monitoring (with optional pressure sensor).
Status of the metal detector will switch to ERROR (i.e. relay K2 “OFF”) if the air pressure is too low.

Note: Optional pressure sensor required.
Note: low air has to be set in IN/OUT MENU

Default: no

BIN DOOR

yes enables bin door monitoring (with optional photo sensor). If the bin door is open for more than BIN ERROR seconds the metal detector will switch to ERROR 22 Bin door.

Note: Optional photo sensor required.
Note: bin door has to be set in IN/OUT MENU

BIN ERROR seconds

sets duration after which a BIN DOOR and BIN FULL error is triggered.
Default: 1 sec
Range: 1-999 sec

PHOTO EYE ERR mm

Setting for systems with internal conveyor.
The value has to be set to 3x METAL PHOTO mm.

Refer to MENU > PRODUCT MENU > REJECT MENU > METAL PHOTO mm

If the photo sensor is blocked and after the conveyor belt moved the indicated distance for this parameter, the metal detector will switch to ERROR 23 Photo Sensor. The error is self clearing after the photo sensor is unblocked. Conveyor has to be restarted manually.

Default: 300 mm
Range: 0-9999 mm

Note: Optional photo sensor required.
Note: reject sync has to be set in IN/OUT MENU

BLOCKAGE FUNCTIONS

BLOCKAGE sec

Adjusts the time the blockage photo sensor has to be permanently blocked before the ERROR 21 BLOCKAGE is triggered.
BLOCKAGE sec. is active when any of the digital inputs in IN/OUT MENU is set to blockage.

Default: 10 sec
Range: 1-99 sec

Since V1.51f22
Range: 0-99 sec

Note: With blockage sec = 0 every product will trigger the ERROR 21 BLOCKAGE

POST BLOCKAGE

Since version 1.50c

Determines the status of the conveyor belt when the blockage of the photo sensor is removed.

• Conveyor stop:
  • Error automatically resets 3 seconds after removal of blockage.
  • Conveyor has to be manually restarted. Same behaviour as in version before 1.50c.
• Conveyor same:
  • Error automatically resets 1.5 seconds after removal of blockage.
  • Conveyor automatically returns to the same status as before the blockage.

CAUTION: If conveyor same is chosen, the conveyor can automatically restart after the blockage is removed. Make sure that nobody can reach into the product stream.

Note: Optional photo sensor or external 24V DC signal required.
Note: an input blockage has to be set in IN/OUT MENU
