Port 15X1 is designed as follows on the component side:
Table 15: Pin assignment of the device connector: Port 15X1
Pin
Function
1
24 VDC power supply (±5 % / 1A - fuse max. 1A)
2
Ready for operation (output: 24 V -> ready to operate, 0 V -> error)
3
Enable (input: 24 V -> start/pressure build-up, 0 V -> stop)
4
0 VDC (reference potential to 24 VDC power supply)
5
Acknowledge faults (= reset) (input: 24 V impulse ≥ 10 ms)
6
Warning (output: 24 V -> warning, 0 V -> no warning)
7
Parameter set bit 1 (= parameter input 1) (digital input: 24 V/0 V selection or
starting of functions; assignment via parameter [F2.19])
8
Parameter set bit 2 (= parameter input 2) (digital input: 24 V/0 V selection or
starting of functions - assignment via parameter [F2.20])
Via pin 1 and pin 4, the pressure sensor HM20 is supplied with 24 V voltage and
the feedback of the ready-to-operate state and warning state is realized via a relay.
Pin 2 provides the output of the "Ready-to-operate" message (24 V) or the "Error"
message (0 V) (not ready-to-operate = fault). This output is a relay output
(relay output 1) and can also be set via parameter [E2.15 or F2.40] to provide
other signals.
For further information on the allocation of inputs and outputs with functions,
see the chapter "CytroPac functions" of the commissioning instructions
51055-IB, see chapter 1.2 "Required and amending documentation".
The digital input (input X1) of pin 3 is used to issue the release
(24 V: Release, 0 V: Stop). In the premium version, the release is set via
the control word in the condition as supplied. However, this can be done via
the digital input if you change the release source, as shown in Table 16.

converter, series EFC x610, see chapter 1.2 "Required and amending
documentation".
