2. 4. 2. Use of 230 V AC Contactor Outputs
Outputs can be directly connected to the coil-side of contactors for light-chain switching
(check contactor’s coil voltage!). Use PC software to distribute switching combinations.
Example is shown at Table 2.

Table 2: Indicating LEDs and contactor outputs
Green LEDs indicate estimated switch-level combination (no averaging delay) due to current
light condition. Red LEDs indicate current status of 230 V AC outputs (averaging affected).
For example : At first level LED-A is lit when light conditions are within the limit set for L1.
After preset averaging time, the red LED-A and contactor output A will be switched on.
2. 5. Calibration
Each photometer is incarefully factory calibrated. Calibration date and information are stored
in device’s memory and also visible on side sticker. Recommended recalibration interval is 2
years.
