The used binary inputs can differ from
project to project. Please refer to the valid
wiring diagram.
6.2.5. Binary Signal Outputs
6.2.6. Electrical Characteristics of the Signal
Outputs
The outputs all consists of voltage free contacts
with the following properties:
6.2.7. Output relay states
The following table indicates the state of the
available output relays, S1 to S7:
Capacitors discharged / No power supply Apparatus closed and supplied FSK-II S+ open and supplied
S1 — ∕ — (open) — ∕ — — — — (closed)
S2 — ∕ — — — — — ∕ —

Table 7 States of output relays
Designation Description Observation
S1 CB Open
This output is a copy of the “OPEN” position as determined
by the sensor
S2 CB Close
In the event of an error, the CPU activates the watchdog
alarm
S3 Aux. CB Open
This output is a copy of the “CLOSE” position as determined
by the sensor
S4 Aux. CB Close
This output is a copy of the “CLOSE” position as determined
by the sensor
S5 Unit Ready
Standby indicator for:
• Correct capacitor charge
• Coil continuity
• Valid and coherent position indication
• <10 faulty switching attempts
S6 WD Ready
Self-monitoring signal of CPU – readiness
Closed when:
• WD in NOT READY = CPU is not working properly or MABS
not supplied
Open when:
• MABS is supplied AND CPU is working
S7 Undervoltage detection
Display of the input Y7 with 100 ms response delay
Closed when:
• Under voltage is low (active) = voltage failure
Open when:
• Under voltage is high = voltage correct
