Electrical installation
If the protective field is broken very briefly, a lockout together
with the error message 14 may occur in the case of heavily
rebounding contacts (Table, below).
The "Action" column gives the required measures.
If the contact monitoring is provided by externally connected
devices, terminals 5 and 6 must be bridged.

Test input
The test input is used to initiate a test cycle (Fig. 10, Appen-
dix). The LGT including the primary relay and response time
are monitored to ensure that they are functioning correctly. If
a safety-relevant error is detected during the test, the
switching elements remain open. The machinery can thus no
longer resume its work. An N/C contact must be connected to
the test input.
Safety can only be guaranteed if the test input is used
(installed in the machine controller).
