*) Note
- Terminals 24, 25, 26 and 27 can be used for external seat-lift sensors as well as for any digital input. Always use an external NO
sensor.
- Two external signals can be connected, they are associated with feedback signals 3 (seat-lift 1) and 4 (seat-lift 2). External sensor
must always be a 8-30 or 110 VAC NO 2 wire sensor. Connect ~ common on terminal 26. The signals from the external sensors
are associated as follows: sensor signal on terminal 24 (seat-lift 1) associated with feedback 3 (seat-lift 1), and sensor signal on
terminal 25 (seat-lift 2) associated with feedback 4 (seat-lift 2).
**) Note
Jumper present = NO. The selection NO/NC is done by the jumper. If changing the function a power recycle is necessary.
Note!
Remember to isolate wires that are not in use.
