5.4 Switching mode 3
Switching mode 3 was developed specifically for twin solenoids (actuating elements). If input 1
has no signal, output 2 is switched. If input 1 receives a signal, output 2 is deactivated first. After
deactivation, there is a pause **. Output 1 is then activated.
The situation is different if the signal at input 1 is cancelled. Output 1 is deactivated first, followed
by a pause **, after which (not before) output 2 is switched back on. Input 2 determines the dura-
tion of the pause **. The duration of the overexcitation pulse is set at inputs 3 and 4.

Input 1 Output 1 Output 2
0 VDC 0 VDC +UB
+24 VDC +UB 0 VDC
Input 3 Input 4 Pulse
0 VDC 0 VDC 1 ms
+24 VDC 0 VDC 2 ms
0 VDC +24 VDC 5 ms
+24 VDC +24 VDC 10 ms
Input 2 Pause **
0 VDC Pulse x 2
+24 VDC Pulse x 1
** Pause: Period between de-energisation of solenoid 1 and energisation of solenoid 2 or vice
versa. It results from the overexcitation time (pulse) multiplied by 2 or 1.
