(Display for
each contact)
Yellow Lit when input or output is ON.
Red Lit when error is detected.
Output: External load disconnec-
tion
Input: Sensor disconnection
Clear as follows:
Output: For manual recovery, clear
error and then restart. For auto-
matic recovery, clear error.
Input: Clear error.
Red Lit when error is detected.
Output: External load short-circuit
(for DRT2-OD16SLH(-1) only)
Input: Sensor power supply short-
circuit
Clear as follows:
Output: For manual recovery, clear
error and then restart. For auto-
matic recovery, clear error.
Input: Clear error.
OFF Lit when input or output is OFF.
I/O Green I/O power is being supplied.
OFF I/O power is not being supplied.
