Function
Vi<: The device automatically switches off
with an adjustable delay time**. It switches on
if the input voltage is in the correct range. The
switch-on voltage is adjustable*.
Vi>: The device automatically switches off
without delay time (protection against
overvoltage). It switches on if the input
voltage is lower than the adjusted switch off
threshold*.
The device automatically switches off; manual
restart is necessary.
LED "Vo" = OFF; LED "collective failure"= ON
LED "Io>" = ON; After 3 seconds the device
automatically switches off; automatic restart
after 15 seconds (for 3 times).
After 30 seconds follows an automatic
shutoff; manual restart is necessary.
The device automatically switches off with
delay time. It automatically switches on if the
temperature is lower than adjusted switch on
threshold. LED T> is on.
Additionally the fan voltage and current
characteristic is monitored to detect a
defective fan. This is indicated by a blinking
LED T>.
