Testing And Maintenance
BE1-CDS220
Purpose: To verify that all alarms are cleared and no alarms are active before initially loading the
system.
Reference Commands: RA, RG-STAT, RA=0, RA-REL=0
Refer to Section 6, Reporting and Alarm Functions, Major/Minor/Logic Programmable Alarms, for
information on setting alarms and retrieving and resetting alarm reports. To use the optional front panel
HMI, go to screen 1.2, \STAT\ALARMS\ALARM.
Major/Minor/Logic Programmable Alarms
Reset and verify that the relay Major/Minor/Logic Programmable alarms are not ON. Alarm information
can be read by transmitting the ASCII commands RA or RG-STAT. To clear (reset) a relay
Major/Minor/Logic alarm, first gain write access to the reporting functions (R password) and then initiate
the RA=0 or RA-MAJ/MIN/LGC=0 commands or press the RESET key while the optional front panel HMI
screen 1.2.1, \STAT\ALARMS\DETAILS screen is displayed.
Purpose: To verify that all Major/Minor/Logic Programmable alarms are cleared and no alarms are active
before initially loading the system.
Reference Commands: RA, RG-STAT, RA=0, RA-MAJ/MIN/LGC =0
Refer to Section 6, Reporting and Alarm Functions, Major/Minor/Logic Programmable Alarms, for
information on setting alarms and retrieving and resetting alarm reports. To use the optional front panel
HMI, go to screen 1.2.1, \STAT\ALARMS\DETAILS.
Targets
Reset and verify that there is no target information. Target information can be read by transmitting the
ASCII command RG-TARG. To clear (reset) a relay target, first gain write access to the reporting
functions (R password) and then initiate the RG-TARG=0 command or press the RESET key while the
optional front panel HMI screen 1.1, \STAT\TARGETS screen is displayed.
Purpose: To verify that all targets are cleared before initially loading the system.
Reference Commands: RG-TARG, RG-TARG=0
Refer to Section 6, Reporting and Alarm Functions, Fault Reporting, Targets, for information on setting
targets and retrieving and resetting target information. To use the optional front panel HMI, go to screen
1.1, \STAT\TARGETS.
Fault Summary Reports
Reset and verify that new fault summary directory records are set to zero. To reset the new fault summary
directory records, first gain write access to the reporting functions (R password) and then initiate the RF-
NEW=0 command two times. Verify that there are no new fault summary records by initiating the RF
command and observe that the NEW FAULTS line indicates zero or view the optional front panel HMI
screen 4.1, \REPRT\FAULT.
Purpose: To verify that there is no new fault records before initially loading the system.
Reference Commands: RF, RF-NEW=0
Refer to Section 6, Reporting and Alarm Functions, Fault Reporting, Fault Summary Reports, for
information on retrieving fault summary reports.
Sequence of Events Recorder (SER) Function
Reset SER registers and verify that there are no SER events. SER directory reports can be read by
transmitting the ASCII command RS or through the optional front panel HMI screen 4.2. To clear (reset)
SER registers, first gain write access to the reporting functions (R password) and then initiate the RS-
NEW=0 command.
Purpose: To verify that all SER registers are cleared before initially loading the system.
Reference Commands: RS, RS-NEW=0
