AUTO-TEST
· AUTO-TEST signal: On terminals 7/8 is present one N.C.
contact. When the door detector detects malfuction, the
auto-test system opens the 7/8 contact to report the fault.
· Door close signal input: Connect the door close signal
contact in terminals 9/10. This signal is used to not allow
the lift door curtain to work with door closed.
