Reflecting plate Green: light ON Red: light ON If the indicators operate as described in the table, the E3X can operate in stable condition within the rated temperature range. 2. Even when the green indicator is OFF, the E3X will operate stably if the operating temperature change since the initial settings is within 10C. 9 9
