Chapter 8 - Checking I/O
ABB

Inspection of analog input signals to S800 I/O modules must be done by
reading the actual value of the measurement in group 4 (81 and 82
optionals) Actual Values (S800 I/O values) of AMC table.
Pt-100 temperature measurement signals can be checked by
disconnecting one wire from sensor end. The signal should then go to
the negative value and sensor failure fault should appear (AMC table
group 85)
Other type of analogue signals should be tested by changing the analog
signal value as primary as possible.
8.2 Converter Internal Signals
The following internal wiring may have been done on site (depending on
the drive configuration also) and should thus be checked:
• Internal fiber optics of FSCD boards to INT board on the next unit.
• Firing through (FT) link, which is an optical link between all INT
(and PINT) boards.
• Power Forward Link in case of multidrive configuration.
• Status indication of both door monitoring and doorlock monitoring
signals of each medium voltage cabinet.
• External EOFF and ESTOP wiring.
• Wiring of internal EOFF signal (from COU doors).
• Interlocking and status signals of grounding switch.
• Cabinet temparature supervision signals.
• Control and supervision signals of optional output isolator.
• Control and status signals of excitation circuit breaker in case of
ACS 6000sd drive.
8.3 External I/O
All external signals are shown in application related circuit and terminal
diagrams and in I/O list. Project related circuit diagrams must be
referred in order to check what optional supervision functions are wired
to ACS 6000 control.
8.3.1 Motor Signals
Motor may have the following optional signals:
1 Typically the synchronous motor has at least the following
instruments giving binary signals: cooling water flow indicators, oil
flow indicators, jack-up oil pressure indicators, oil filter condition
