3. Installation guidelines
•Do not expose the control unit to direct sunlight in order to prevent overheating of the circuit board.
•Connect the control unit to a continually powered line to allow SHUT DOWN CLEANING when the fan stops and
to have maximum precision in the ΔP measurements.
•Protect the control unit from rain, water infiltration and humidity. Incomplete closing of the cover may cause
infiltration which can seriously damage the circuit board.
•Do not have cables entering via the upper part of the Control unit box.
•Do not install any electronic devices on vibrating structures.
•Use only cable glands with protection grade IP65 and of proper size (according to the cable used).
•A disconnecting switch has to be installed on the power line before the control unit.
•Do not attempt to repair the control unit – contact Simatek!
•All wiring has to be carried out by a qualified electrician to prevent any risk of fire and electrical shocks.
•The control unit wiring has to be performed in such a way that the different types of cables, (power, relay’s
contact, valve output, 4-20 mA output) are kept separated and not passing close by the PCB.
•Before opening the unit, make sure that the control unit is switched off (switch on/off [1] on 0 and wires on
clamps [4] disconnected), including connection to alarm/signal relays.
•All the control unit electrical connections, including solenoid valves, have to use separate paths in respect to the
other loads.
•Voltage selector’s jumpers have to be positioned only by skilled personnel and following the instructions.
•A wrong voltage selectors jumpers positioning may cause potential danger to the personnel safety.

1. Check that the Simatek GFCD 32 does not have power (on/off switch [1] on 0 and terminals [4] disconnected).
2. Check that the supply voltage, indicated on the yellow label [22] as “IN” corresponds to the available power
supply (Voltage and Frequency.)
3. Check that the supply voltage to valves, indicated on the yellow label [22] as “OUT” corresponds to the
voltage/frequency as indicated on the coils.
5. Electrical connections
1. Unscrew and remove the terminals cover [20].
2. Check that Simatek GFC 16 does not have power (on/off switch [1] on 0 and terminals [4] disconnected).
3. Extract the removable terminals [2].
4. Check that the supply voltage to valves indicated on the yellow label [22] as “OUT” corresponds to the
voltage/frequency as indicated on the coils.
5. Connect the valves to the terminal blocks [2], between terminal C and the numbered outputs.
6. Earthing [3] of the valves is necessary when output voltage is ≥48 V.
7. NEVER connect the Common or valve output to earth [3].
8. The Commons are interconnected on the printed circuit board.
9. The outputs are “static” type, with “zero crossing” command, to prevent electrical disturbances.
10. Check that the valve connections are correct and isolated in regard to earthing, by measuring the isolation
between Ground [3] and Common with outputs terminal.
11. Put the extractable terminals back in place.
12. Replace the terminals cover and replace the screws [20].
6. Filter taps
It is very important that dust and liquid are not allowed to enter into the hose couplings, as this will damage the
instrument. Any dust clogging in the hose connections may also result in indication errors, so protection by a
filter element is recommended.
For documentation regarding these DP filters, please see documentation for the DP filter.

NOTE!
Select the shortest Pulse Time possible, between all those compatible with maximum obtainable particle separation.
This is valid both in Manual and Automatic Mode.
•Ideal time for “bag” filters: between 100 ms and 400 ms.
•Ideal time for “standard cartridge” filters: between 500 ms and 1 second.
•Ideal time for “rotating nozzle cartridge” filters: between 1 sec and 4 seconds.
7.3.1 Manual mode operation
In Manual Mode, the Simatek GFCD 32 commands the valves with fixed Pause Time. The cleaning is not dependent on
the level of the clogging of the filter bags. The Manual Mode is to be used during the start-up phase only.
When the Simatek GFCD 32 is in Manual Mode, the LED Manual [30] flashes.
In Manual Mode, the Pause Time depends on selected Manual Pause Time.
7.3.2 Automatic mode operation
In Automatic Mode, the cleaning is automatically adapted to the level of the filter bag clogging. The cleaning starts
when the filter ΔP exceeds the value of selected Set Delta-P (see 7.2). The Set Delta-P to select depends on the
structural characteristics and wear and tear of the filter and on the type of process.
When the Simatek GFCD 32 is in Automatic Mode, the LED Manual [30] is off.
In Automatic Mode, the Pause Time depends on the selected Automatic Pause Time.
7.3.3 Remote switching
It is possible to pass from Automatic Mode to Manual Mode (and vice versa) closing a remote contact. See below:
1. Unscrew and remove the terminals cover [20].
2. Connect to terminals A.M and Ground [26] an external contact free of power and normally open (NO).

contact on terminals A.M and Ground [26].
5. To return in Automatic Mode, open the remote contact on terminals A.M and Ground [26].
8. Shut down cleaning
After every utilization, it is useful to carry out one or more cycles of Shut down cleaning, to free the filtering elements
of residual dust. Shut down cleaning starts when the ΔP goes below 0.10 kPa.
CAUTION:
Shut down cleaning only starts if the Simatek GFCD 32 is in Automatic mode!
In order to activate Shut down cleaning:
1. Check that the unit is in Automatic mode.
2. Select the Number of Cycles of Shut down cleaning (see 7.2). (Select 0 to exclude the Shut down cleaning).
3. Set the Pause Time in Pause in After Cleaning Cycle. (see 7.2).
4. The Shut down cleaning starts when the ΔP goes below 0.10 kPa. On the display [7] flashes the letter P. Shut
down cleaning does not start from the valve no. 1, but completes the current cycle, counting it as the first cycle
of Shut down cleaning. During Shut down cleaning, if the filter ΔP exceeds 0.15 kPa, the cleaning stops.
5. When Shut down cleaning finishes, on the display [7] appears End.

Each time the differential pressure in the filter exceeds the set
Value, bag cleaning starts. Bag cleaning stops, when the ΔP
drops below the set value.
ΔP Start/stop is set in Kilopascal (1 kPa = 100 mm WG).
15.4 Pause time – ΔP-Cleaning
By ΔP-Cleaning, the pause time should be set to a very low
value, as the control itself regulates how often the filter is
cleaned.
However, the pause time must correspond to the compressor
capacity to ensure that the compressed air is admitted at full
pressure during the whole cleaning sequence.
See Simatek’s filter manual regarding compressed air consumption.
15.5 Pause time – Shutdown cleaning
The pause time during shutdown cleaning may be set as required according to the properties of the dust in question,
however, the pause time must be correspond to the compressor capacity.
15.6 Shutdown cycles
Bag cleaning will continue during the set number of cycles (first valve to last valve) after the ΔP in the filter has
dropped below 0.10 kPa (the fan is off).
Any equipment for removal of the separated dust should run during shutdown cleaning.
Simatek recommends 2-3 cycles, as the current cycle is regarded as the first shutdown cycle. Therefore the first cycle
will not necessarily be a full cycle.
Shutdown cleaning only works during ΔP-cleaning. If the ΔP in the filter exceeds 0.10 kPa during shutdown cleaning,
the function will be interrupted, and ordinary bag cleaning will start.
15.7 ΔP Alarm
Each time the differential pressure in the filter exceeds the set value, an alarm is given. If required, the signal may be
led to e.g. a control room.
ΔP Alarm is set in kPa.
