3. Installation guidelines
• Do not expose the control unit to direct sunlight in orde r to preve nt over he a ting of the circuit b o ard.
• Connect the control unit to a continually power ed line to allow S HUT DOW N CLEANING when the fan s top s 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 d amage the circui t b o ard.
• 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 prop er size (ac co rd ing to the cable us ed).
• A disconnecting switch has to be installed on the power line befo re the co ntro l unit.
• Do not attempt to repair the control unit – contact Sim atek!
• All wiring has to be carried out by a qualified electri c ian to prevent any r isk of f ire and electri c al s hocks.
• The control unit wiring has to be performed in in such a way that the different typ es of cables (po wer, relay’s
contact, valve output, 4-20 mA output) are kept separated and no t pass ing cl ose by the PCB.
• Before opening the unit make sure that the control unit is switched off (switc h o n/off [1] on 0 and wires on
clamps [4] disconnected, including conne c tion to alarm/signal relays.
• All the control unit electrical connec tions, including solenoid valves, have to use separate paths in respect to the
other loads.
• Voltage selector’s jumpers have to be positio ne d only by skilled personnel and following the instructions.
• A wrong voltage selector s jumpe rs po s itioning may cause potential danger to the personnel safety.

3. Extrac t the removable terminals [2].
4. Make sure that the suppl y voltage to valves indicated on the yellow label [22] as “OUT” corresponds to the
voltage/frequency as indicated on the coi ls .
5. Connec t the valve s to the terminal blocks [2], between terminal C and the numbered outputs.
6. Earthing [3 ] of the valves is necessary when the output voltage is ≥ 48V.
7. NEVER connect the Common or valve output to earth [3].
8. The Commons are inte rconnected on the printed circuitry.
9. The outputs are “s tatic ” type , with “ ze ro -crossing” command, to prevent electrical disturbances.
10. Check that the valve connections are correct and isolate d 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 [20] and tighten the screws .
6. Filter taps
It is very important that dust and liquid are not allowed to enter into the hose co up lings, as this will damage the
instrument. Any dust clogging in the hose connec tions may also result in indication errors, so protection by a filter
element is recommended.
For documentation regarding these DP f ilte rs , p le ase see documenta tio n for the DP filter.

NOTE!
⋅ Valves are pulsed from outlet No. 1 onwards.
GFCD 16
⋅ Check that during the first cleaning cycle ev ery v alve is activated.
⋅ If manual mode is used we suggest setting the Simatek GFCD 16 working p aram e ters to
clean the filter at the lowest possible frequenc y , ther eby reducing the little dust escape
arising during jet-pulsing, achieving a longer lifetime of filter bags/cartridges and reducing
the compressed air consumption.
⋅ Pause time should allow an efficient filter c le a ning in the worst co nditio ns , but should never
be shorter than the time needed to re-pressurise the compressed-air tank!
⋅ While selecting parameters (in Sele c t menu), S imate k GF CD 16 w ill return to normal
operation if no buttons are pressed within a 5 minute inter val.
8. Remote control
ATTENTION!
Simatek fits the Simatek GFCD 16 unit with a connectio n on termina ls Remote and Commo n [26].
If you wish to operate Simatek GFCD 16 with a remote switch, read the instruc tions below. If you do not wish to take
advantage of this opportunity, do not remove the conne c tion.
To activate Remote:
1. Unscrew a nd remov e the terminals c o ve r [20].
2. Remove the connection from terminals Remote and Common [26].
3. Bring an exter nal no-load and normally open (NO) contact to Remote and Common terminals [26].
4. Replace and s crew the terminals cover [20] tight.
5. Close the contac ts on the Remo te and Com mon termina ls [26 ] in order to enable the Remo te functi o n.
6. Should yo u open the contact on Remote and Common ter minals [2 6] the Simatek GFCD 16 will stop working.
Close the contact in order to start the cleaning cycle again from the position where it stopped.
9. Shut down cleaning
We suggest operating one or more cycles of Shut down cleaning at the end of each working session in order to remove
the residual dust of the filter. Shut down cle aning is s tarte d each time the ΔP of the filter goes below 0.10 kPa.
A free contact of the fan can be connecte d betw e e n clamp s F and C. The contact has to be close d w he n the fan is on.
In this case Shut down cleaning will not start until the fan is switched off .
The Shut down cleaning will start any time the ΔP goes below the value of 0.10 kPa and the contact is open.
ATTENTION!
Shut down cleaning will only start if Simatek GFCD 16 is in Automatic mode!
Shut down cleaning will only start if ΔP Pre-coating has already been exceeded, otherwise Shut down cleaning will not
start even if the fan is switched off.
In order to activate Shut down cleaning:
Check that the Simatek GFCD 16 is in AUTOMATIC mode.
Select the NUMBER OF CYCLES of Shut down cleaning (see 7.2 ).
(Select 0 to exclude Shut down cleaning).
Shut down cleaning starts when the ΔP goes below 0.10 kPa, and the fan contact (betw een F and C) is ope n. LED Shut
down [33] will then flash. Shut down cleaning will start from the next valve and will consider the existing cycle as the
first cycle.
Once Shut down cleaning is completed LED Shut down [33] will remain o n.
10. Pre-coating function
Pre-coating delays the beginning of the filter c le aning c ycle in ord er to allo w the filte r elements to form a thin dust
cake on their surface.
ATTENTION!
If you select ΔP Pre-coating, cleaning will start only after having reached set ΔP Pre-coating both in Automatic and
Manual mode disregarding the Operating ΔP value.

Stabilize the filter ΔP, press the key “-” [10] to reset the unit.
PPP: The maximum value of ΔP in the Simatek GFCD 16 has been exceeded (3.00 kPa).
Stabilize the filter ΔP, press key “-” [10] to reset the unit.
P---: ΔP value is <0.50 kPa.
In this case check that the filtered taps are correctly connected to the pressure ports of the Simatek GFCD 16
as described in paragraph 6.2.
if the problem continues:
Disconnect the tubes between the filtered taps and pre s s ure por ts .
Adjust the DP indication to 0 kPa as indicated on page 11, paragraph 13.
Connect the tubes between the filtered taps and pres s ure ports .
SB: the Remote contact is open [26].

Recommended pause times for SimPact® 4T/4T-R
GFCD 16
18. Factory settings/Program menu
18.1 Pulse time
Simatek recommends a pulse tim e of 0.2 sec.
18.2 Pause time – Continuous
By continuous cleaning, the pause time is calc ulate d fr o m a
total cleaning time for the filter of 180 sec.
See recommended pause time by continuous cleaning for the
current filter type.
18.3 ΔP Start/stop
Each time the differential pressure in the f ilte r exc eed s 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).
18.4 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 filte r is
cleaned.
However, the pause time must correspond to the compressor
capacity to ensure that the compressed air is admitted at f ull
pressure during the whole cleaning seq ue nce.
See Simatek’s filter manual regard ing com pr e sse d -air consumption.
18.5 Pause time – Shutdown cl eani ng
The pause time during shutdown cleaning may be set as requir e d acco rd ing to the prope rtie s of the dus t in ques tion,
however, the pause time must be correspond to the compressor capacity.
18.6 Shut down cycles
Bag cleaning will continue during the se t number of cyc le s (firs t valv e to last valv e ) afte r 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 shut down cleaning.
Simatek recommends 2-3 cycles, a s the current cycle is regarded as the first shut down cycle. Therefore the first cycle
will not necessarily be a full cycle.
Shut down cleaning only works during ΔP-cleaning. If the ΔP in the filter exceeds 0.10 kPa during shut down cleaning,
the function will be interrupted, and ord ina ry bag cle aning will s tart.
18.7 ΔP Alarm
Each time the differential pressure in the filte r exc eed s the set value , an alarm is g iven. If required, the signal may be
led to e.g. a control room.
ΔP Alarm is set in kPa.
