SPECIFICATIONS
1. The response time varies depending on the number of expansion units connected.
2. The orange LED is normally part of the bar graph LED monitor. It is used as a calibration
indicator during the setting of the sensitivity.
3. When several units are connected, the allowable ambient temperature changes depending
on the following conditions. To connect several units, be sure to mount them to a DIN rail
(metal DIN rail). Make sure that the output current is 20 mA. max.
• When 3 to 10 units are connected: -10 to +50 °C (14 to 122°F)
• When 11 to 16 units are connected: -10 to +45 °C (14 to 113°F)

SELECTING DISPLAYED DATA
■ Displaying received light intensity
Received light intensity is displayed approximately 4000 is the
maximum setting.
Note: The MAX and MIN values vary depending on the fiber unit
connected.
■ Displaying excess gain
Received light intensity is converted by defining the setting value as
100 P (%).
■ Displaying the hold value
The peak value or the minimum value of the received light intensity or
excess gain is displayed.
The setting of the output selector switch determines whether the peak
value or the minimum value is displayed.
