IMER TEST
It is possible to test timers by using the output (67). The test
is performed like the time delay test for current relays.
The following is the connection schematic.
Connect the start of the timer to the normally open or
normally close contact of sockets (67), depending on the type
of timer under test. Connect the output of the timer to STOP
input sockets (65). Start the test pressing ON+TIME: the timer
will measure the time between the closing of the contact and
the intervention of the timer.
