• 240-W Model Output Terminals
• 480-W Model Output Terminals
(5) I/O Signal Terminals
Connect the external outputs and external tripping inputs.
TRP Tripping Alarm Output Turns ON to indicate when an abnormal voltage
or current was detected and the output was cut
off (The photoswitch output will turn OFF.).
LOW Undervoltage Detec-
tion Output
Turns ON when the 24-VDC output voltage
from the S8AS falls below the threshold.
(The photoswitch output will turn OFF.).
LFE Maintenance Forecast
Monitor Output
Turns ON to indicate when the number of years
to the set replacement time has been reached
(The photoswitch output will turn OFF.).
TMP Over-temperature
Output
Turns ON to indicate that the temperature
exceeded the over-temperature output thresh-
old (The photoswitch output will turn OFF.).
