FUNCTIONAL DESCRIPTION
After activation of the Emergency-stop push button, the K1/K2 LED will turn OFF, indicating that the three internal
safety relays K1 and K2 are de-energized. The normally open safety outputs 13/14...33/34 will open. There exist two
different start modes:
Manual start mode: see note (B) next page
1. After removing the stop condition, press the START push button to start the safety control module.
2. The K1/K2 LED will turn ON indicating that the internal safety relays K1 and K2 are energized. The three
normally open safety contacts will close allowing the machine to operate.
Automatic start mode: see note (B) next page
1. After removing the stop condition, the safety control module will immediately reset.
2. The K1/K2 LED will turn ON indicating that the safety relays K1 and K2 are energized. The three normally open
safety contacts will close allowing the machine to operate.
IMPROPER AUTOMATIC START MODE IN PERIMETER GUARDING APPLICATIONS
• If the module is in the automatic start mode, another part of the safety control circuitry must keep the
latched function engaged.
Failure to comply with these instructions could result in death or serious injury.
