4.
Preliminary checks
1.
Check that the Simatek GFC 32 does not have power (switch on/off [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 end 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 32 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 [2] back in place.
12.
Replace the terminals cover [20] and replace the screws.
