Both a global and a local re-calibration inputs are available. The local input starts calibration only on the selected sensor, while the global input works for the entire system. These inputs give the possibility of using the line control system or an external switch to decide when to initiate calibration.

The IS240 Tab Verifier sensor have been specially engineered with short and narrow casing for easy fitting into the available space on a typical press (see illustration opposite). The control box with its easy to read signalling system is similarly compact for convenient mounting.

The IS240 Tab Verifier is a modular system allowing inspection on up to four lanes with one controller. For each shell, the system gives a good and/or bad output signal. Error checks are performed continuously and if any system fault is found, the warning output is activated. Plug-in modules on the controller allow operators to quickly re-route inputs while a fault is being diagnosed, which helps to keep unplanned downtime to a minimum.
