WARNING
•
This Instruction Sheet only provides descriptions for electrical specifications, general specifications,
installation & wiring, troubleshooting and peripherals. Other detail infromation about programming and
commands is compatible with ELC-PC/PA/PH series; please see ELC Application Manual. For more
information about the optional peripherals , please see individual product manual.
•
This is an OPEN TYPE Controller. The ELC should be kept in an enclosure away from airborne dust, humidity,
electric shock risk and vibration. Also, it is equipped with protective methods such as some special tools or
keys to open the enclosure, so as to avoid the hazard to users and the damage to the ELC.
•
Never connect the AC main circuit power supply to any of the input/output terminals, as it will damage the
ELC. Check all the wiring prior to power up. To avoid any electromagnetic noise, make sure the ELC is
properly grounded
. Do NOT touch terminals when power on.
•
Battery replacement: use UL component type: TDRTL-2150/S lithium battery. Refer to following table for
battery life. (NOTE: RTC should be reset after changing battery).
