Outputs
K1:
Relay, 16(6)A 250V~, normally-open contact
Please note:
Relay K1 is connected in series with input E1
(high pressure switch) Relay K1 can only be energized if E1 is closed!
K2:
Relay, 16(6) A 250V~, normally-open contact
K3:
Relay, 16(2.2) A 250V~, normally-open contact
K4:
Relay, 8(1.5) A 250V~, change-over contact
ST-Bus communication interface
Interface driver: RS485, galvanically not separated
The network has to be installed in lines topology and terminated with a 120 Ohm resistance on each side.
In case of networking always connect port “A” with port “A” and port “B” with port “B”. Crossing over is not
permissible!
