SUMMARY:
DESCRIPTION :
The SDS3 is a sequencer for the command and control of dust-
removal equipment.
It can be equipped of the differential or relative pressure measure
(pressure drop).
It is equipped with a T1 time (pulse time), a T2 time (rest/idle), a
T3 time (rest time between two cycles), a T4 time which performs a
cleaning cycle if the sequencer has not operated for a set number of
hours, a manual running, an electrical fault control, a possibility to
execute a preset number of cycles at fan stop, three pilots for
pneumatic valves.
In option, it can be equipped of a relay output for fault or alarm
report of information and of a loop control input (I1: fan or other).
If the device is equipped of the pressure measure, it is equipped
with a loop control to DP measure (2 thresholds), two P alarms
(high and low), a P threshold for accelerated cycle, a T2A time
(accelerated idle time).
The device is adjustable depending on the use.
All the operating parameters are adjustable through sensitive keys
on the front.
The value of each parameter and the pressure are displayed on a
LED display.
Comment: this data sheet is drawn up on the basis of a device
equipped with the pressure drop measure. If the device is not
equipped with the pressure drop measure, the functions relating
to this are not validated. The options on the device, define the
terminal board and the Glands configurations.

- Fan stoppage operation:
If the stoppage of the fan is detected, the cycle in course terminates and the defined number of cycles is carried out.
Comment: if the re-start of the fan is detected during the execution of the parameterised number of cycles, a classic
operation is started.
The fan stoppage can be detected in 2 ways (set in the factory): through loss of the input I1 or, if it’s equipped with
the DP, through the disappearance of pressure (as soon as it becomes lower than a value variable from 5 to 20
daPa).
If there is a DP sensor present, the setting of the type of detection of the fan stoppage takes place through a hidden
menu:
- Access to the concealed menu: activate the « Reset » key at least one second, release it, less than one second
after activate the « Select » key at least one second, release it.
- Mode selection with the + and - keys:
- « PEt » display: detection of the stop fan through loss of I1 output
- « Pdp » display: detection of the stop fan through DP drop
- Choice validation using the « Select » key
- If « PdP » choice:
- set the stop fan detection value (from 5 to 20 daPa)
- Value validation using the « Select » key

detection method of the fan stoppage)
oDP order present (if cycle controlled by DP: « AdP » choice)
-If fan stoppage detection is through TOR input:
oIf loss of the input I1, the stoppage of the fan is established: the sequencer carries out the parameterised
number of cycles and stops. If the parameterised number of cycles is set at 0: the sequencer stops
instantly or terminates the cycle in course according to the chosen stoppage mode.
- If fan stoppage detection is through pressure drop:
oIf loss of input I1, the sequencer stops instantly or terminates the cycle in course according to the chosen
stoppage method.
oIf the fan stoppage is established: the sequencer carried out the parameterised number of cycles and
stops. If the number of parameterised cycles is set at 0: the sequencer stops instantly or terminates the
cycle in course according to the chosen stoppage mode.
- If loss of the DP order (if cycle controlled by DP: « AdP » choice), the cycle stops instantly or terminates the
cycle in course according to the chosen stoppage mode.
