2.1 Operating the device
In the initial position the front switch (1) is in position "off" and all load outputs are
switched off. The status LED (2) lights up red. If the switch is set to "on", the 6 load out-
puts are switched on one after the other at intervals of approx. 3 seconds (configurable).
The status LED flashes green. The status LED flashes once for the first load output,
twice for the second load output, etc. until the status LED flashes six times for the last
load output. At the end the status LED lights up permanently green.
If you now want to switch off the loads with a delay, set the switch to "off" and the output
switching-off process is carried out every 3 seconds in reverse order to the switch-on
process. The status LED flashes red six times and the sixth (last) load output is
switched off. Then the fifth load output follows until at the end of the sequence the first
load output is also switched off. The status LED is now permanently red. The sequence
during the switch-off process is configurable.
A switch-on or switch-off sequence cannot be interrupted. The position of the switch
(1) is only taken into account again at the end of a sequence.
Operation with optional external switch
.
If a jack plug with switch is plugged into the jack socket (3), the front switch (1) loses its
function and the device can only be controlled via the external switch. As with the front
switch, closing the switch starts the switch-on sequence when all load outputs are off.
Opening the external switch initiates the switch-off sequence when all load outputs are
on. If an LED is connected to the external switch, the LED will be permanently lit at the
end of the power-up sequence. If all load outputs are switched off, the switch LED
flashes slowly.
Overvoltage Protection
The device has an overvoltage protection (SPD) (
EPS 8112-2 / EPS 8112-4
). This is based
on input-side varistors with a thermal fuse between phase (L) and neutral (N) and a gas
discharge tube to ground (PE) to protect the internal electronics and the load outputs
with failure detection (thermal fuse permanently tripped). The status of the protection is
indicated by an LED (4) on the front panel. If the LED is green, it means that the protec-
tion is ready for operation, if the LED flashes red, it means that the overvoltage protec-
tion module is out of order. Each surge protection module is designed to discharge a vir-
tually unlimited number of surge pulses in normal installation environments. In an envir-
