※1 Terminal bases are different. (See "2-3-2 "Terminal Base Alignment and FOCAS-2000 inner connection.)
※2 You can set to synchronize alarm signals output from contacts with alarm lamps by operating the panel switch (when you set, wash, and warm up the detector).
Initially (when the detector is shipped from the factory), its panel is set to output no contact alarm but the alarm lamps singly blink (to alarm).
※3 Alarm1 and Alarm2 values can be set individually (in ppm) in the range of 5 to 15 ppm.
※4 RECout (4-20mA output) outputs a direct current of 4 to 20mA in synchronism with the measured oil concentration value.
