7.2 Parameters selection
Check that all electrical connections have been done as described in Paragraph 5.
Switch on/off [1] on 1. On the display [7] appears, for a few seconds the Simatek GFCD 32 identification code.
Immediately after, on the display appears the value of the filter ΔP. If the LED OK [18] and Pause [12] turn on and the
LED Continuous [30] flashes, the Simatek GFCD 32 is in Manual Mode. If only the LED OK [18] turns on, the Simatek
GFCD 32 is in Automatic Mode.
Choose between Manual or Automatic Mode, with Automatic button [16]. In Manual Mode the LED Manual [30]
flashes; in Automatic Mode it is off.
ATTENTION! When the fan stops, the display [7] must indicate a filter ΔP value of 0 kPa. Otherwise, use the
regulation [15] to reset the indication at 0.
1) Press SELECT MENU [9]:
The No. 1 will flash on the display [7]:
Using the +/– buttons [10] select the Pulse Time (0.01-9.99 sec).
2) Press SELECT MENU [9]:
The No. 2 will flash on the display [7]:
Using the +/– buttons [10] select the Manual Pause Time (1-999 sec).
3) Press SELECT MENU [9]:
The No. 3 will flash on the display [7]:
Using the +/– [10] buttons select the Set Delta-P (0.01-9.99 kPa). The cleaning
starts every time that the filter ΔP exceeds the Set Delta-P (+0.05 kPa). The
cleaning stops every time that the filter ΔP goes below the Set Delta-P.
4) Press SELECT MENU [9]:
The No. 4 will flash on the display [7]:
Using the keys +/– buttons [10] select the Automatic Pause Time. (1-999 sec)
5) Press SELECT MENU [9]:
The No. 5 will flash on the display [7]:
Using the keys +/– [10] buttons select the Pause in After Cleaning Cycle (1-99
sec).
– The Shut down cleaning automatically starts when the filter ΔP goes below 0.10
kPa.
6) Press SELECT MENU [9]:
The No. 6 will flash on the display [7]:
Using the keys +/– buttons [10] select the No. of Cycles of Shut down cleaning (0-
99 times). (Select 0 to exclude the After Cleaning Cycle) The After Cleaning Cycle
automatically starts when the filter ΔP goes below 0.10 kPa.
7) Press SELECT MENU [9]:
The No. 7 will flash on the display [7]:
Using the keys +/– buttons [10] select the Set Delta-P Alarm (0.01-9.99 kPa).
When the filter ΔP exceeds the Set Delta-P Alarm, you are in the presence of
alarm.
8) Press SELECT MENU [9]:
on the display [7] appears P000: the cycle starts.
LED PULSE [11] will indicate that a valve is activated.
LED PAUSE [12] will indicate that Simatek GFCD 32 is waiting to activate the next
valve.
NOTE!
⋅The valves are activated from outlet No. 1.
⋅The Simatek GFCD 32 automatically skips any disconnected outlets. The relative numbers run, in rapid
succession, on the display [7]. If there are no valves connected, the display will show the numbers of all
outlets.
⋅Check that during the first cleaning cycle none of the connected valves are skipped.
⋅We suggest setting Simatek GFCD 32 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 filter
bags/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.
⋅Press the Delta-P/Valves button [14] to return in run from every step of Select menu. To change a parameter
value immediately returning in run: a) enter Select Menu, until the step of the desired parameter; b) change its
value; c) press Select Menu; d) press Delta-P/Valves.
