Relay Connection
10.1
K1 Relay
The K1 relay serves to actuate a digital purge valve. The necessary back-up fuse for a purge valve is integrated in the
connection chamber of the
SILAS
Controller
. The fuse rating is selected depending on the coil data.
To use purge valves of type 03-5110-.... the following ratings are factory-fitted:
Mains voltage AC 230 V
valve fuse 80 mA time lag
Mains voltage AC 115 V
valve fuse 160 mA time lag
Mains voltage DC 24 V
valve fuse 500 mA time lag
10.2
K2 Relay
The K 2 relay signalises the enabling and switches on if in zone 2 Use (PRG YES), the pre-purging time has ended and the
pressure value of P1 is exceeded or if in zone 22 Use (PRG NO) only the pressure value of P1 is exceeded. The K 2 relay
stays switched on if the value falls short of P 1 (MIN). Only in the PRG YP2 function does the K 2 relay switch off. If “P 4”
(MAX) is exceeded, K 2 relay switches off for the duration of the increased overpressure.
10.3
K3 Relay
Set the S 2 rotary switch at pos. 9. The following functions are assigned with the “+” and “-“ keys. The selection is saved by
pressing the “SET” key. The saved value is marked with “*”.
