IDEC SmartRelay Manual
Note
Fluctuating analog values are due to screening on the connecting
wire from the analog valuator device to the analog FL1B-J2B2
IDEC SmartRelay expansion module (encoder wire) that has either
been mounted incorrectly or not at all.
To avoid fluctuating analog values when using these expansion
modules, proceed as follows:
• Use only shielded encoder wires.
• Shorten the encoder wire as much as possible. The encoder
wire must not be more than 10 meters long.
• Clamp the encoder wire on one side only and clamp it only to
the PE terminal on the FL1B-J2B2/FL1D-K2B2 expansion mod-
ule.
• Connect ground on the encoder supply to the PE terminal on the
expansion module.
