Safety Monitoring Functions
Many types of safeguarding and safety devices and safety related signals can be
connected as inputs to the CR30. The Connected Components Workbench
(CCW) facilitates the selection and connection of the device. Each block is
assigned the next available settings for input terminals, test sources number of
inputs, pulse testing, discrepancy time, and input filter.
Emergency Stop The Emergency Stop function block sets the parameters for typical emergency
stop push buttons. In the CCW, click and drag (or double-click) the block to an
available Safety Monitoring Function spot. When mechanical operated contacts
are used, these contacts must be direct-acting contacts.
