Green LED displays at the front plate signalize that there is an inverse output signal. – In two separate channels, you can set eight command values from 0 to +10 V, using in each case four internal potentiometers: P1 to P4 (channel 1) P5 to P8 (channel 2). – The individual command values are called up via the external enable signals (switching signals +24 V) that are allocated to the potentiometers: Command 1–1 to command 1–4 (channel 1) Command 2–1 to command 2–4 (channel 2). – The selected call-up is signalized by means of yellow LED displays: LED 1 to LED 8. – Command value signal linking. If more than four internal command values are necessary, up to eight command values can be processed by feeding in the output UA2 (channel 2) into channel 1.

The cable shield must be connected to the control cabinet extensively and as short as possible. – The valve solenoid must not be connected to free-wheeling diodes or other protection circuits. 100 24 V= Mains Connector DIN 41612 - F 32 5/6 6/6 Bosch Rexroth AG Hydraulics VT-SWKA1-5-...
