DESCRIPTION
:
SET18DP is an adjustable device for control and full
automatization of dedusting equipments, whose declogging is done
by pressured air injections.
Permanent control of differential pressure allows an optimal
efficiency according to the whole parameters, for any type of
exploitation and product.
It is equiped of a sequencer and a differential pressure switch or
relative pressure switch (load loss dP).
It has 18 outputs to be linked to solenoïd valves with electric
default check, 1 loop control input (I1), 1 relay output for default or
alarm report, and in option, 1 analogic output 4-20mA for report of
loss pressure measure dP information.
The device is adjustable, according to the use of it, with several
levels, protected by passwords.
All the running parameters can be seen and adjusted on the
front panel of the device, thanks to a graphic colour touch screen
Interface is multilingual.
Evolution of the declogging cycle, the running defaults and the
pressure loss measure are clearly displayed and detailed.
A graphic representation of pressure loss allows to easily check
its level.
The device has a counter of cycles which have been done and
records mini and maxi measured pressures.
Remark : this notice is based on a device equipped of pressure
loss measure, with 18 outputs and with a 4-20 mA output. In case
the device is not equipped of 4-20 mA output, functions linked to it
are not taken into consideration. The quantity of outputs defines the
terminals and glands configuration.

we have.
Level 0 : it is not possible to change any parameter, we can only see the parameters.
Reset of faults is possible. Manual running is possible. Change of language is possible.

According to the password entered, corresponding level is active.
Remark : if password is not correct, we move to level 0.

Adjustable from 3 to 255 1/100th seconds (reachable at level 1 or above).
2 : T2 : rest time between two pulses of declogging SV.
Adjustable from 1 to 255 seconds (reachable at level 1 and above ).
3 : T2A : second rest between two pulses of declogging SV.
T2A time (shorter than T2) replaces T2 time if accelerated running (pressure>threshold T2A).
Adjustable from 1 to 255 seconds (reachable at level 1 and above ).
4 : T3 : rest time between two declogging cycles.
Adjustable from 0 to 255 minutes (reachable at level 1 and above). If adjusted to 0 : not active.
5 : T4 : maximum time without declogging cycle.
If the device did not have any declogging cycle for the quantity of hours which is adjusted, the ongoing cycle is stopped
(if stop in cycle) and a declogging cycle is launched.
Remark: T4 time is reset at each pulse on any SV.
Adjustable from 0 to 255 hours( reachable at level 1 and above ). If adjusted to 0 : not active.
6 : Quantity of declogging SV.
Adjustable from 1 to 18, according to the quantity of SV which are connected (reachable at level 1 and above).
7 : Adjustment of the type of declogging stop, in case we lose the running order :
« End of cycle » : the ongoing cycle ends up.
« On cycle » : cycle stops during its running (at the SV where cycle is, at the end of the T2 time). It will start
again where it was. (reachable at level 1 and above).

Page parameters 2/4:
1 : We choose if dP order is or isn’t taken into consideration to launch declogging cycle (reachable at level 1 and
above). « with dP » : declogging depends on dP order.
« without dP » : declogging does not depend on dP order.
2 : Threshold Maxi dP : if measure dP is above this threshold, more than one second, dP running order moves to
« ON » status (reachable at level 1 and above).
3 : Threshold Mini dP : if measure dP is below this threshold , more than one second, dP running order moves to
“OFF” status (reachable at level 1 and above).
Remark : if threshold Maxi dP=0 and threshold Mini dP=0, then the dP running order is forced on « ON » status.
4 : Threshold T2A : threshold corresponding to accelerated running (reachable at level 1 or above ).
If measure dP is above this threshold more than 5 seconds →accelerated running →T2 = T2A
If measure dP is below this threshold more than 5 seconds →normal running
Note : if threshold T2A is adjusted to 0, the function is not active (always in normal running).
5 : Threshold High Alarm dP (reachable at level 1 or above).
If measure dP is above this threshold more than 5 seconds →High Alarm dP
If measure dP is below this threshold more than 5 seconds →No High Alarm dP
Note : If threshold of High Alarm is adjusted to 0, the function is not active (no High Alarm dP generated)
6 : Threshold Low Alarm dP (reachable at level 1 or above).
If measure dP is below this threshold more than 5 seconds →Low Alarm dP
If measure dP is above this threshold more than 5 seconds →No Low Alarm dP
Note : If threshold of Low Alarm is adjusted to 0, the function is not active (no Low Alarm dP generated)
7 : Display of measure of instantaneous load loss dP.
8 : Adjustment to zero pressure (reachable at level 1 and above).
Allows to make a calibration at 0 pressure. Put the device out of pressure (disconnect the two pressure
connections) and press this area : zero pressure is calibrated.

Page parameters 3/4:
The device can detect a fan stop, by two ways : by I1 input or by measure of load loss dP. When it moves from
running fan state to stop fan state : the quantity of declogging cycles is done.
Remark : if during the achievement of the indicated number of declogging cycles, the fan stops and starts again,
the running declogging cycle stops and we start again with standard running.
1 : Choose the type of detection for fan stop(reachable at level 1 or above) :
«by input I1loss » : the stop of the fan is detected if I1=0.
Remark : the running of the fan is detected if input I1=1
«by dP loss » : the stop of the fan is detected if the load loss measure is lower than the value indicated on the
next parameter (see point 2).
Remark : the running of the fan is detected if the load loss measure dP is higher than the indicated value,
more than 5 seconds.
2 : If the type of detection of fan stop is « by dP loss», this value shows the detection threshold (reachable at level
1 and above). Adjustable from 5 to 20 daPa.
