Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20℃ +68℉.
2) Complies with those standards only when the controller is used in combination with the sensor head ST4-□.
3) If the total current of the control outputs (OSSD1, OSSD2), auxiliary outputs, and muting lamp output exceeds 400 mA, the wiring resistance between the controller and the power supply should be 1 Ω or less. In addition, if the total current is 400 mA or less, the wiring resistance between the controller and the power supply should be 2 Ω or less.
