2.6 Time Delays
Check the time delays when troubleshooting problems
with transfer switch operation.
Use the View Time Delays screen to check the settings
for the adjustable time delays. Figure 2-9 shows the
factory settings and adjustment ranges for the
adjustable time delays.
Observe the controller’s display to identify which time
delay is executing at any given time. Initiate a test and
observe as each programmed time delay executes.
See Section 3.6, System Test. Compare the operation
to the test sequence illustrated in the flowcharts in
Figure 3-13 or Figure 3-14.

2.7 Reset Data
Be sure to read and understand the information in this
section before resetting.
2.7.1 Reset Maintenance Records
Reset the maintenance records after transfer switch
service to update the last maintenance date and totals
since reset that are displayed in the maintenance
records screen.
2.7.2 Reset Event History
Resetting the event history clears the events from the
event history log. The event history can be saved to a
file before reset. See Section 2.7.5, File Maintenance.
2.7.3 Reset Default Parameters
Resetting to the default parameters will reset all
parameters, including the system voltage and
frequency, to a factory default setting. The default
system voltage and frequency settings may not match
the settings for your application.
The transfer switch will not operate correctly if the
system voltage and frequency do not match the
sources. Use the Set Sources screen to set the system
voltage and frequency after resetting to the default
parameters. See the operation/installation manual for
instructions.
2.7.4 Reset and Disable Test Password
Reset the Test password to return the test password to
the default, 0000.
Disable the test password to allow the user to start a test
without entering a password.
Note: Disable the test password only during service
unless the transfer switch is installed in a secure
location.
2.7.5 File Maintenance
Use the File Maintenance screens to remove unneeded
files or save the event history. See Figure 2-10 and
Figure 2-11.
Files can also be transferred to a mass storage device
connected to the USB port on the logic board. Refer to
the transfer switch operation/installation manual for
instructions to transfer files.
