TEST
The TEST function can be activated by pressing the 24VDC normally-open push-button
connected to TX unit TEST input (pin 2 of M12-5 poles) for at least 0.5 seconds.
The TEST disables the emission stage, so the RX side sees interrupted all beams and the
OSSD goes low within response time.
As shown in the timing diagram below, the OSSDs go OFF (BREAK status) after 500msec
(plus a cycle time) and after the response time of the light curtain.
