Meaning and use of the individual signals
Valve unit 3 [PM-E F terminal 9,10 (channel 0 P/M)]
Signal state channel 0 = "0"
Valve in the locked neutral position
Signal state channel 0 = "1"
Valve in the flow position
Not assigned [PM-E F terminal 13.14 (channel 1 P/M)]
Not assigned [PM-E F terminal 11,12 or channel 15,16 (channel 2 P/M)]
Shutdown of the power supply for the following external standard DO module (terminal 11,12
or terminal 15,16)
Signal state, channel 2 = "0"
The supply power at the two P1/P2 voltage buses for the following standard DO module is
switched off.
Signal state, channel 2 = "1"
The supply power at the two P1/P2 voltage buses for the following standard DO module is
switched on.
Power module PM-D F 24 V DC PROFIsafe
The power module can switch off fail-safe the SG 1 to SG 6 voltage buses using six digital
outputs. The outputs are implemented using two P switches. There is a main power switch
for all six shutdown groups and six subsequent (downstream) individual switches for each
shutdown group.
The voltage bus U 1 (electronics power supply for the motor starter) is supplied with 24 VDC.
If an overvoltage or undervoltage condition exists, U 1 is shutdown through two P switches
and the subsequent (downstream) motor starters are brought into the passive state. If the
motor starter is safely shutdown, U 1 is not shutdown.
Through the six available shutdown groups (SG1...SG6), the power module is, among other
things, suitable for supplying fail-safe motor starters such as F-DS1e-x and F-RS1e-x.
