iseg CC23 User Manual

SL1
Potential-free current source (8 to 10 mA) to supply a safety loop for up to 10 modules. The safety loop is routed through the
modules SL connectors by a series connection. Start- and end point of the safety loop is SL1. For modules with a Redel connector,
the associated SL pins have to be bridged. Additional potential-free contacts to open the safety loop through external signals can
also be inserted.
SL2
A current source on crate GND potential for modules with option SLP (internal supplied safety loop). The SL2 connector pins can
be bridged by a short-circuit plug or an external potential-free switch. In this case the modules are supplied with the loop current
via the crate's backplane.
To enable a module its SL connector (and, if applicable, the SL pins on the Redel connector) must be bridged. All modules are
supplied with the loop current in parallel, i.e. opening the SL connector on a module will only deactivate this one module.
