proportional outputs are configured, the following
conditions may occur:
- The instrument is set for one output only and an
OVERRANGE is detected, the OUT 1 turns OFF (if
reverse action) or ON (if direct action).
- The instrument is set for heating/cooling action and an
OVERRANGE is detected, OUT 1 turns OFF and OUT 3
turns ON.
- The instrument is set for one output only and an
