Chapter 8 - Checking I/O
After all parameter settings have been done, certain internal and
external I/O signals must be tested.
When parameter setting has been completed, it is reasonable to clear
the fault logger and re-boot AMC board by cycling the auxiliary power.
Drive should be in local mode and in "ReadyOn"-state with no alarms or
trips active. This way observing correct operation of the signals and
drive is possible.
8.1 Checking Principle
Main principle is that the wiring which has been implemented on site
only should be tested.
Note that correct operation of main circuit breaker signals will be tested
also later in connection with charging / discharging test.
8.1.1 Digital Inputs
All signals should be checked as primary as possible meaning that the
state of each sensor should be changed. Checking of binary input
signals is done by changing the state of each input in process side, that
is CBs, contactors, etc. If state of switch can not be changed, test is
done from the nearest terminals of the device.
All signals are connected to S800 IO modules. S800 I/O modules have
led indication of input status for each channel and an indication of trip /
alarm is shown in SW.
• In CDP panel the alarms are displayed in Actual Signal Display
Mode. The alarm name should correspond (in relation) to input
signal name shown in circuit diagrams.
• In DriveWindow the alarms are displayed in “Fault Logger” display.
Name of each signal is the same as in CDP and in circuit diagrams.
8.1.2 Digital Outputs
Cabling can be checked by forcing the status (setting / releasing with
jumper) on I/O modules end.
8.1.3 Analog Inputs
External analog signals mainly consist of temperature measurements.
Pt-100 sensors may be used for stator winding, cooling air and bearing
temperature supervision. Also transformer temperature may be
measured with Pt-100.
