1.4.1 Jack Plug Accessory
The Expert Power Sequencer 8112 can optionally be remote controlled by an external
switch with cable. The Jack Plug Adapter 7960 (3.5 mm, 3-pole) can be purchased as
an accessory.
The jack plug (1) is plugged into the front panel of the EPS 8112. Between (2) and (4) an
external potential-free switch is connected. An possible additionally LED (3) in the
switch can be controlled. This LED is internally connected to 5V with a 560R resistor.
1.5 block diagram
This block diagram illustrates the structure of the EPS 8112-4. Other models do not
have overvoltage protection and line filters, or have a different type of load outputs.

2 Operating
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-

12

Operating
onment with many high-energy overvoltage pulses, aging of the overvoltage protection
element can cause a permanent failure of the function.
The surge protection function can only be restored by the manufacturer of the
device. Normally, the device will continue to operate even after the failure of the protect-
ive function.
2.2 Configuration
The EPS 8112 is configured in the delivery state in such a way that the ports are
switched on one after the other every 3 seconds. The switch-off process takes place at
the same interval, but in reverse order. The preset values are chosen in such a way that
normally no adjustments are required. If one uses the EPS 8112 e.g. in a media control
with amplifier, one can arrange the devices in such a way that the amplifier is switched
on last, but switched off first. However, one has the possibility to change the waiting
times and the order of switching off.
Initiate programming mode
a) You enter the programming mode when you switch on and off 2 times. Each switch-
ing operation must be < 2 sec. After that the LED flashes alternately red-green.
b) Please make sure that the ports of the EPS 8112 are switched off so that the pro-
gramming mode can be started.
c) The programming mode is exited directly when the external connector is plugged in.
d) During programming mode, the optional LED for overvoltage protection is not active.
Resetting all values (3 sec switch-on delay and descending switch-
off sequence.)
a) Start programming mode.
b) Switch to "On" within 3 sec.
c) After 5 sec. the red-green change flashes faster.
d) Wait another 5 sec, the LED flashes 3x red.
e) Turn off, and the EPS 8112 is in the switched off state (outside programming mode).
Reversing the direction of the switch-off process
a) Start programming mode.
b) Switch to "On" within 3 sec.
c) After 5 sec. the red-green change flashes faster.
d) Switch off within 5 sec, the LED flashes green 3 times.
e) The EPS 8112 is in the switched off state (outside programming mode).
Set all ports to the same waiting time
a) Start programming mode.
b) Wait 3 sec, the LED flashes 3x orange.
c) If you stay off for 5 sec, you are out of programming mode.
d) Switch to "On" to set the time, the LED flashes red every second.

13
Expert Power Sequencer 8112 © 2021 GUDE Systems GmbH
Operating
e) After the desired time switch to "Off" (for N seconds - N x flashing).
f) The EPS 8112 is in the switched off status (outside programming mode).
The minimum waiting time when switching on is 2 sec. and the maximum time is 60
sec, even if a different time has been configured. The waiting time when switching off is
always fixed at 3 sec.
Example: All ports set to 10 sec
·2x switch on and off (programming mode)
·wait 3 sec. - LED flashes 3x orange
·switch on - wait 10 sec. - switch off
Set one or more ports to a waiting time
a) Start programming mode
b) To select the Xth port, switch on and off X times.
If you switch several times and wait more than 5 sec. in position "On", the program-
ming mode will be left.
c) Wait 3 sec, the LED flashes green X times.
d) If one does nothing for 5 sec, then one is out of the programming mode.
e) To set the time, switch to "On", the LED flashes red every second.
f) Switch off after the desired time (for N seconds - N x flashing).
g) Now the X+1th port is selected, switching on continues at b), waiting 3 sec. contin-
ues at c).
The minimum waiting time when switching on is 2 sec. and the maximum time is 60
sec, even if a different time has been configured. The waiting time when switching off is
always fixed at 3 sec.
Example: Set the time of port 2 to 7 sec, port 3 to 8 sec. and port 5 to 10 sec.
·2x on and off (programming mode)
·switch 2x on-off - selects port 2
·wait 3 sec. - LED flashes 2x green
·switch on - wait 7 sec. - switch off
·wait 3 sec. - LED flashes 3x green
·switch on - wait 8 sec. - switch off
·5x switch on - off - selects port 5
·wait 3 sec. - LED flashes 5x green
·switch on - wait 10 sec. - switch off
·Wait 5 sec, EPS 8112 exits programming mode
