Application
Safety systems are comprised of many components. No one safety
component will insure the safety of the system. The design of the complete
safety system should be considered before you begin. It is very important to
follow applicable safety standards when installing and wiring these
components.
The unit SR131/SR231 is a safety module for monitoring of magnetic
switches with a normally closed and a normally open contact each.
The unit is suitable for the following applications up to control category 4
in accordance with EN 954:
• Safety door locks with magnetic switches.
• Monitoring of several doors with one module.
The module provides two potential free safety contacts and two solid-state
signal outputs. In case of a direct use in a category 4 cut-off circuit the two
safety contacts 13-14 and 23-24 must be connected in series. The contact
multiplication by means of contactors with guided contacts is shown in the
wiring diagram.
Due to the redundant design of the unit the occurrence of a single fault does
not lead to the loss of the safety function. All detected faults are displayed
through the solid-state signal output Y34.
After connecting the supply voltage to the terminals A1-A2, the module runs
an internal test. During this test, all LEDs in the panel in the device cover
are illuminated for 2 seconds and the transistor outputs Y34 / Y44 are
activated in this time.
If all connected magnetic switches are actuated and the starting circuit
Y1-Y2 is closed, the safety outputs are activated. The contact change
between normally closed and normally open of a magnetic switch must
occur within a period of 0.5 seconds. An unused input (e.g. S21-S23) must
be jumpered.
It is imperative that an external fuse be connected as shown on the
"WIRING DIAGRAM FOR MODULE SR131/SR231 SAFETY RELAY".
For maximum protection of the outputs, please refer to "TECHNICAL
DATA".
