Setup of the input and output switching lines of the metal detector. Set up the parameters according to the devices connected to IN1 – IN8 and OUT1 – OUT 8 terminals on the mainboard.
Terminals on SHARK mainboard corresponding to INPUT LINE 1 – INPUT LINE 8:
| INPUT LINE 1 = Terminal 9 | INPUT LINE 3 = Terminal 13 | INPUT LINE 5 = Terminal 17 | INPUT LINE 7 = Terminal 21 |
| INPUT LINE 2 = Terminal 11 | INPUT LINE 4 = Terminal 15 | INPUT LINE 6 = Terminal 19 | INPUT LINE 8 = Terminal 23 |
NOTE: A photo sensor connected to an input must be PNP type. PNP = The 24V are swicthed through to the photo sensor output.
Functions of INPUT LINE 1 – INPUT LINE 8:
| met/err reset | HIGH: Returns immediately to normal operation mode after METAL or ERROR. LOW: Normal operation Errors can be reset even if metal alarm is still pending. Resets ERROR and METAL at the same time. Note: Check setting of METAL CONTACT (in product menu > reject menu) for behavior of METAL outputs. |
| conveyor on/off | HIGH: Changes status of conveyor to START / STOP / RESET immediately LOW: Normal operation Belt control push button input (START / STOP / RESET) |
| e-stop | HIGH: sets OUTPUT start conveyor to low. Conveyor start is prohibited Sets ERROR 29: emergency stop. Sets OUTPUT error. Set OUTPUT MD inactive to inactive. LOW: Resets ERROR 29 emergency stop Conveyor can be started as normal Since version 1.51f |
| start teach | HIGH for minimum 2 sec.: Start TEACH LOW: Normal operation Required parameter settings: PRODUCT MENU > TEACH SETUP > TEACH EXTERN > yes |
| reject test | HIGH: Trigger reject device immediately. LOW: Normal operation |
| reject valid | HIGH: Normal operation LOW: After time set in SYSTEM MENU > BRC MENU > REJECT CONF ms: Reject confirmed The reject is validated when this input sees a minimum of two edges high/low or low/high after a ‘metal’ or ‘pusher’ output was activated. If no edge signal within REJECT CONF ms after METAL OUT , ERROR 4 Reject is triggered. For two digital inputs ‘reject valid‘ in the IN/OUT MENU, both inputs have to see an edge signal (AND logic, typically used with InLiquid, InMeat). Also refer to the ‘bin full‘ input, which can also be used for reject validation. |
| reject sync | HIGH: Normal operation LOW: Photo sensor triggers pusher to product centre Required parameter settings: PRODUCT MENU > REJECT MENU > METAL CONTACT> push1 or push2 |
| reject safety | HIGH: Normal operation LOW: Reject device is locked in position NORMAL, e.g. during cleaning. |
| keypad lock | HIGH: Keyboard is locked, no data entry possible. LOW: Normal operation Typical application: Key switch. |
| low air | HIGH: Normal operation LOW for more than 100ms: Triggers ERROR 7 Low Air Required parameter settings: SYSTEM MENU>BRC MENU>LOW AIR>YES Monitors compressed air. |
| start cip | HIGH: Activates CIP mode immediately LOW: Normal operation Required parameter settings: SYSTEM MENU > CIP MENU |
| bin full | HIGH: Normal operation LOW: For more than 30 sec.: Triggers ERROR 6 Bin Full (set duration after which ERROR is triggered at SYSTEM MENU > BRC MENU > BIN ERROR sec.) Monitors reject bin. Input ‘bin full‘ can also be used for reject validation AND for bin full. Reject validation: When there are two digital inputs ‘bin full‘ configured in the IN/OUT MENU, at least one of the two inputs has to generate an edge to validate the reject (OR-logic, typically used for BD). The bin full functionality remains unchanged with two inputs, i.e. if one of the two inputs is blocked for more than 30 seconds the ERROR 6 Bin Full is triggered. (set duration after which ERROR is triggered at SYSTEM MENU > BRC MENU > BIN ERROR sec.) If less than two of these inputs generate an edge signal within REJECT CONF ms, ERROR 4 Reject is triggered. Required parameter settings: SYSTEM MENU>BRC MENU>BINFULL>YES |
| met count reset | HIGH: Resets METAL COUNTER after 3 seconds LOW: Normal operation |

Allows fast product switching if the frequency, attenuation and amplification settings do not change from one product to the other. The fast switch time is then 0.2 seconds, while normally switch time is 1.5 to 2.0 seconds. Fast switch is available since version 1.51f05. Required settings: PRODUCT MENU > TEACH SETUP > REMOTE PRODUCT > no |
| met/err key | HIGH: Returns to normal operation mode after METAL or ERROR (only available with option: key switch). Note: Check setting of METAL CONTACT (in product menu > reject menu) for behavior of METAL outputs.

Only available with key switch. |

| test no reject | HIGH: Activates metal test mode LOW: Normal operation (only with option: key switch). During test mode the conveyer is immediately stopped when metal ist detected (output ‘error CW‘) – however, the metal alarm is neither counted nor entered in the event report. Timeout of the test mode is controlled by SYSTEM MENU>CIP MENU>CIP Timeout min – after this time has elapsed normal metal detection continues. While the test mode is active TEST is displayed. |
| CW rejects | HIGH: Signal to checkweigher in case of metal alarm. LOW: Normal operation Can also be used together with one or two ‘reject valid‘ inputs as reject validation for the checkweigher reject. In this configuration ( ‘reject valid‘ together with ‘CW rejects‘)the reject valid timeout timing starts with ‘CW rejects‘ activation – not with the ‘metal‘ or ‘pusher‘ output pusher activation. |

| VtoF converter | This output takes the speed signal measured at the S2a analog input and converts it to a pulsed signal with 500 clicks per meter on a configurable digital output. This output signal can then be used to distribute the exact same speed signal to an encoder input on one or multiple S2a units for exact and consistent position measurement. Available since version V1.52f https://docs.cassel-inspection.com/uncategorized/output-vtof-converter |
