Three mounting possibilities:
PROTECTION AND CONNECTIONS:
It is possible, depending on the version of the box, to modify the supply voltage and the voltage of the solenoid valves
by positioning jumpers on the electronic board.
The jumpers are set at the factory for a supply voltage and a solenoid valve voltage corresponding to the version
ordered.
Check or position the jumpers according to the desired voltages.
The jumpers are accessible after removing the front panel.
The connection terminal blocks are accessible after removing the connection cover (lower part of the box).
Warning: changes of jumpers and connections must be made with the power off

FRONT FACE :
SETTINGS AND OPERATION:
The various parameters are adjusted as follows:
- Press the "SELECT" key until the yellow "menu" led lights up in front of the parameter to be set and press the "+"
and "-" keys to obtain the desired value.
- Then return to the "CYCLE" position using the "SELECT" key. Each parameter is saved in a memory when going
to the next step or when automatically returning to the "CYCLE" position.
Remarks :
- The return to the "CYCLE" position is automatic after 60 seconds.
- Each parameter can be viewed at any time during the operation of the device.
See the correspondence with the number below.

1) Visu Cycle:
In this position, the CYCLE menu led is on fixe.
If a fault is present, display of the fault (this display has priority).
If the sequencer is stopped: display "0".
If an unclogging pulse is in progress:
- display of "n x" with x = number of the current SV
- rapid flashing of the menu led in front of T1.
If rest time between two shots in progress:
- display of the time count before the next pulse
- rapid flashing of the menu led in front of T2.
Whether it is an unclogging of n cycles in manual operation, or unclogging due to the detection of a
fan stop, rapid flashing of the menu led in front of the fan / manual
At any time, if the + key is pressed: display of "n x" with x = EV which will be engaged on the next shot.
2) Setting the stop mode:
Two stop modes are possible if loss of loop control (input I1):
- « FcY » for end of cycle: the current cycle ends until the last SV.
- « Sto » for cycle stop: the cycle stops at the EV where it arrived. It will resume at the next EV when
reappearance of the run order
3) Setting the number of outputs:
Number of SV in the cleaning cycle: from 1 to 18.
4) T1 setting:
Activation time of an output (in 1 / 100th of a second) : from 3 to 255.
5) T2 setting:
Idle time between two outputs (in seconds) : from 1 to 255.
6) T4 setting:
If there has been no unclogging for the set time (T4), the current cycle ends (if stopped in cycle)
and a full cycle is performed.
If set to 0: this function is disabled.
Note: the T4 time delay is initialized for each pulse on an SV.
7) Setting the number of cycles when the fan is stopped:
If the loop control is lost (input I1), the stopping of the fan is detected.
In this case, the n cleaning cycles set here are carried out one after the other.
If set to 0: this function is disabled.
8) Manual running:
Setting the desired number of cycles in manual running. The cleaning cycles follow one after the other
(regardless of the state of input I1).

- Sequencer operation:
The unclogging cycle consists of driving the EV outputs one after the other with a T1 pulse time and a rest
time T2 between two pulses.
4 orders can initiate unclogging:
oInput « loop control » (I1) :
▪If input=1 (closed input),
▪Unclogging cycles follow one another as long as the entry=1.
oT4 time :
▪If end of time T4 : execution of a cleaning cycle.
oDetection of fan stop (loss of input I1):
▪The n cycles set are executed.
oManual running :
▪The n cycles are executed.
Note: On power-up, a 10-second delay prohibits unclogging.
- Fault check operation:
When activating an EV, the device monitors the current consumed.
If there has been no consumption, an EV electrical fault is generated (for example: EV no or bad
connected, defective EV coil, etc.).
If power consumption is observed while no EV should be piloted, a fault
electrical short-circuit is generated (for example card failure…).
Electrical faults are maintained until reset by the "RESET" key.
Indication of:
"DEF" if electrical fault short-circuit
"Dxx" if electrical fault on EV with xx = number of EV.
Note : All faults are stacked in memory and are displayed in ascending order of the solenoid valves.
To cancel a fault and go to the next display, press the "RESET" button.
- Relay output:
The relay is energized if there is no fault (contact between 13 and 14).
It is no longer powered if there is an electrical fault (no more contact between 13 and 14).

General instructions for safety, assembly, commissioning, usage and maintenance
to be read before working on the device
I. GENERAL
These instructions must be read jointly with:
+the standard NFC15-100
+the technical data sheet specific to the device
The Sefram devices are designed to be assembled,
commissioned and used in compliance with the
characteristics/data given in the technical data sheet. Always
adhere to all of directives, legislation, orders and most recent
standards in force for the stated field of application.
The assembly, commissioning, usage and maintenance
operations must always be carried out by qualified and
authorized personnel.
Personnel working on the devices must be familiar with the
safety rules and requirements in force regarding the
components, devices, machines and electrical installations.
Before any intervention on the cabinet, the equipment must be
de-energized by cutting off the power source upstream of it.
II. RECEPTION - STORAGE
After unpacking the device, check that this latter has not been
damaged during transport; for certain devices, remove the
protective film from the cover. The material must be stored
inside in a dry place.
In the event of a problem, please contact Sefram.
III. ASSEMBLY
The assembly operations must be carried out by qualified,
skilled and authorized personnel. Personnel working on these
devices must be familiar with the safety rules and requirements
in force.
The box must be mounted vertically.
For material connected permanently to the network, a quickly
accessible cut-off device must be incorporated into the cabling
installation of the building.
The device supply must be equipped with a device for
protection against risks of over-current and fault isolation. The
number of poles protected must be appropriate to the neutral
regime of the building and to the regulations in force.
The equipment must be connected to the PE protection mass
by green/yellow wires (NFC15-100).
The device is compatible with the neutral regimes TT, TN or IT;
Nevertheless, we recommend that the device is supplied
through the intermediary of an insulation transformer for which
the primary is supplied between phases and not between
phase and neutral, so as to avoid any accidental over-voltage
caused when the neutral is cut before the phases.
In the event of a problem, please contact Sefram.
IV. COMMISSIONING AND USAGE
Commissioning is authorized only after duly establishing that
the device, the machine or the installation in which the device
has been integrated in a compliant manner, satisfies all of the
directives, legislation, orders and most recent standards in
force.
Commissioning operations must be carried out by qualified,
skilled and authorized personnel. Personnel working on these
devices must be familiar with the safety rules and requirements
in force.
Note: correct operational functioning does not in itself constitute
an indication of conformity to the recommendations for the use
of the material in complete safety.
Also read the maintenance recommendations which equally
apply during commissioning and use.
In the event of a problem, please contact Sefram.
V. MAINTENANCE
The device does not require any special maintenance.
For devices equipped with the pressure measurement, in order
to retain a precise pressure measurement, an annual
calibration is advised particularly at « zero » (see § calibration
on the technical data sheet)
The following operations are recommended; they constitute a
minimum:
- Before any work intervention, we recommend that the
dust is removed before opening the box,
- The device must not be opened in an excessively
dusty environment,
- The settings must be carried out in the shortest lapse
of time so as not to engender any risks,
- The integrity of the joints must be checked: remove
any trace of dust or other deposit,
- Remove any trace of dust which could have
penetrated during the setting operation,
- Always ensure that the transparent cover is correctly
closed.
Maintenance operations and interventions inside the box must
be carried out by qualified, skilled and authorized personnel.
Personnel working on these devices must be familiar with the
safety rules and requirements in force.
In the event of a problem or any questions during these
operations please contact SEFRAM.
