4.5.2 TEST output
TEST SEQUENCE AT POWER UP / SETTING ON DELIVERY
•
A test of the protective equipment is automatically done at start up to control the
connection of its outputs to the module terminals. For this reason, it is recommended to use
the same power supply source for the module and the protective equipment (or make sure
power is switched on simultaneously with the same switching device).
•
On delivery, the muting module provides a normally closed contact between terminals
28 and 29. All the above mentioned protective equipment need a normally closed contact
on their test input with the exception of the FF-SCAN, the FF-LS and the FF-SPS4 which
need a normally open contact.
•
The test output can be changed to a normally open contact.
•
If the test output is not used, the detection field of the protective equipment must be
interrupted 100 ms after power up, before restarting the module.
