SB4 Module 4CG/165 Safety control unit module
●Function
■The 4-channel sensor card module SB4-4CG facilitates the connection of light barriers or light grids and safety sensors with contacts in a single or two-channel version. It also contains the microcontroller control system for the SafeBox. Only one of these modules is contained in a SafeBox SB4 and it must be plugged-in at position 2.
■There is a plug-in jumper on the module.If the system contains additional assemblies, then this plug-in jumper must be pluggedin to the last plug-in position.
■This module enables a number of separate trip circuits to be installed in one SafeBox.
■On switching on the system the software determines whether a light barrier or a safety sensor with contacts is connected on a channel and then monitors its presence during operation.
■Safety sensors with contacts, which are connected to the SafeBox, must operate in accordance with the normally-closed principle.
■An open contact signifies a "Safe condition".
■Channels 1 and 2 and 3 and 4 can be monitored for concurrence and antivalence. During activated concurrence monitoring 2- channel safety devices are monitored for simultaneous opening and changeover of the signals. The monitoring is carried out over a period of 2 s.
■Antivalence monitoring awaits the normally-closed contact on channel 1 or channel 3 and the normally-open contact on channel 2 or 4. If the antivalence monitoring is operated without concurrence monitoring, then an incorrect contact setting leads to switch off and error signal 7 after approx. 60 s.
