Manual Toggle Switches

Manual toggle switches are an option available on RD8i relay interfaces. Toggle switches allow a relay to be

manually fired on, or forced off, in addition to being automatically operated by a control system. The toggle

switches will operate the RD8i’s contacts as long as power is available to operate the coils even if the relay’s

processor has been damaged or communication has been broken to the master controller.

To force an output on, move the toggle UP and the corresponding indicator will illuminate.

To force an output off, move the toggle DOWN and the corresponding indicator will extinguish.

To allow automatic operation of an output, move the toggle to the CENTER position.

Units with serial numbers 2111xxxx may be field upgraded to manual toggles.
