A trapped key interlocking system
from Castell has reduced downtime
from the bacon-slicing process at
Uniq Prepared Foods.
Uniq replaced the electrical safety switches on its bacon slicer with a panel-mounted KSSE20 multi-key solenoid-controlled switch and four AI access interlocks.
When access to the bacon slicer is required, the machine must first finish its cycle so that a signal is received by the solenoid. The push button is depressed, which energises the solenoid and illuminates the LED, confirming that th Removal of the primary key changes the condition of the electrical supply to the machine to a safe condition. The primary and three secondary keys can then be used to unlock the interlocks on the access doors. The guards can only be opened once the electrical supply has been switched to a safe condition.
