4. Preliminary checks
1. Check that Simatek GFC 16 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 powersupply
(Voltage and Frequency).
3. Check that the supply voltage to valves indicated on the yellow label [22] as “OUT”, corresponds to
thevoltage/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.
-Earthing [3] of the valves is necessary when output voltage is ≥48 V.
-NEVER connect the Common or valve output to earth [3].
-The Commons are interconnected on the printed circuit board.
-The outputs are “static” type, with “zero crossing” command, to prevent electrical disturbances.
6. 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.
7. Replace the terminals cover and replace the screws [20].
6. Settings
6.1 Voltage selection
CHECK:
1. That Simatek GFC 16 does not have power (on/off switch [1] on 0 and terminals [4] disconnected).
2. That the supply voltage indicated on the yellow label [22] as “IN” corresponds to the available supply
voltage.(Voltage and Frequency).
3. That the supply voltage to valves indicated on the yellow label [22] as “OUT” corresponds to the
voltage/frequency as indicated on the coils.
If these 3 conditions are met, go to paragraph 6.2.
Otherwise, carefully follow the procedure below!
A. Supply voltage selection
1. Unscrew the two screws [21] (optional), and open the Simatek GFC 16 transparent cover.
2. Remove the 4 screws of the front panel. Lift the front panel (do not remove it as it is connected to the base of
the enclosure!).
3. Check that the supply voltage selected by jumper [5], corresponds to the one available from the supply
voltage(e.g. both 230 V).
4. Should the two voltages be different, move the jumper [5] in order to select the same supply voltage.
5. Go to point 6.1B.
B. Selection of power supply to the valves
1. Check that the supply voltage to the valves, selectable by jumpers [6] and [6A], corresponds to the supply
voltage indicated on the coils of the valves (e.g. both 230 V).
Jumper [6]: 1HV = 115 V; 2HV = 230 V; LV = 24 V
Jumper [6A]: HV = 115 V / 230 V; LV = 24 V
2. Should the two voltages be different, replace the jumpers [6] and [6A] in order to select the same supply voltage
as indicated on the coils.
Jumper [6]: 1HV = 115 V; 2HV = 230 V; LV = 24 V
Jumper [6A]: HV = 115 V / 230 V; LV = 24 V
CAUTION! Both jumpers [6] and [6A] must correspond to the same voltage!
3. Go to point 6.1C.
