Teach-in key
„Teach“
Setting sequence
Brief activation (< 2 s) of the Teach key or the external digital Teach input makes
it possible to test the system (relay and load), in which case the control input of
the solid state relay is activated.
Longer activation (> 3 s) of the Teach key or the external digital Teach input
makes it possible to record and store the load current of the „Iteach“ load (teach
mode).
Teach mode must be carried out at a constant load current.
Following activation of the Teach key or the external digital Teach input, the
green „INPUT“ LED and the yellow „ON“ LED flash quickly simultaneously
(t
on
= 100 ms) and (t
off
= 100 ms). If the Teach key is pressed for longer or the
digital Teach input is applied for longer (> 3 s) then the two LEDs flash slowly
(t
on
= 1 s) and (t
off
= 1 s) to indicate that teach mode (Iteach) is active.
When the Teach key is released or the external digital Teach input is switched
off, the two LEDs continue to flash for another 2.5 s as an indication that the
new nominal value has been stored.
If this new nominal value is outside the monitoring range of 2 A…40 A
rms
then
the two LEDs flash alternately green and yellow as an indication that diagnosis
is not possible.
The LEDs flash until the teach process is restarted.
