L = phase, N = neutral
On/off switch [1] on 1. The display [7] will indicate for 3 seconds the release code of Simatek GFC 16.
Once the codes disappear, the display will show letter E (run) and the number of the valve which is going to be
activated. LED OK [18] and REMOTE [35] are on.
1) Press SELECT MENU [9]:
1 will flash on display [7]:
Using keys “+/-” [10] select the No. of valves, you wish to connect.
Example: If you wish to connect 4 valves to Simatek GFC 16, select 4.
Should you skip this step of the MENU, Simatek GFC 16 will automatically
set No. of valves as if they were all connected (Simatek GFC 16:4) then 4
valves will be recognized, (Simatek GFC 16:12) then 12 valves will be
recognized.
2) Press SELECT MENU [9]:
2 will flash on display [7]:
Using keys “+/-” [10] select Pulse time (0.01 – 9.99 sec).

Using keys “+/-” [10] select No. of cycles of Shut down cleaning.
Select 0 if you do not wish to have shut down cleaning.
Pause time in Shut down cleaning is the same as the one selected at point 3).
5) Press SELECT MENU [9]:
E1 will flash on display [7] the cleaning cycle starts.
LED 1 [11] will indicate that a valve is activated.
LED 2 [12] will indicate that Simatek GFC 16 is waiting to activate the next
valve.
NOTE!
-Valves are pulsed from output No. 1 onwards.
-Check that during the first cleaning cycle every valve is activated.
-We suggest setting the Simatek GFC 16 working parameters to clean the filter at
the lowest possible frequency, thereby reducing the little dust escape arising
during jet-pulsing, achieving a longer lifetime of filterbags/cartridges and
reducing the compressed air consumption.
-Pause time should allow an efficient filter cleaning in worst conditions, but
should never be shorter than the time needed to re-pressurise the compressed-
air tank.
-While selecting parameters (in Select menu), Simatek GFC 16 will return to
normal operation if no buttons are pressed within a 5 minutes interval.

11. Factory settings/Program menu
11.1 Pulse time
Simatek recommends a pulse time of 0.2 sec.
11.2 Pause time
By continuous cleaning, the pause time is calculated from a total
cleaning time for the filter of 180 sec.
See recommended pause time by continuous cleaning for the
current filter type. However, the pause time must correspond to
the compressor capacity (compressor shall be able to fill the
compressed-air tank between each pulse).
11.3 Shutdown cleaning cycles
Bag cleaning will continue during the set number of cycles (first
valve to last valve) after connection between Fan [36] and
Common [37], (fan stopped).
Any equipment for removal of the separated dust should run
during shut down cleaning.
Simatek recommends 2-3 cycles, as the current cycle is
regarded as the first shut down cycle. Therefore the first cycle
will not necessarily be a full cycle.
