AC Fail Indication Delay
The AC Fail Indication Delay feature provides the option to delay generation of a trouble signal upon the loss of AC power. Refer to
Table 3.1 for UL-compliant settings.
Default Mode
When using the power supply in Default Mode: DIP switch positions 7 and 8 are used to select the AC Fail Indication Delay as listed below:
Retrofit Mode
When using the power supply in Retrofit Mode: DIP switch position 7 is used to select the AC Fail Indication Delay as listed below:
DIP switch position 8 is used to select which trouble relays will report any AC and ground faults.
Refer to “AC Trouble Relay” on page 36, for operation of internal NAC trouble relay in response to AC loss.
Operating Modes
The power supply operates primarily in Default Mode or Retrofit Mode, depending on the installation. While in either mode, the power sup-
ply can be placed in two special, temporary operating modes per settings described in Table 3.8. These modes are Change Output Circuit
Configurations and Display Trouble History.
Upon completion of either of these two modes, the system must be placed back in Default or
Retrofit operating mode. Note that the current operation of all outputs will not be affected or disturbed while in either of these two special
operating modes.
Default Mode
This is default operating mode of the power supply (the mode configured when the unit is shipped), and is compliant with UL 864 10th Edi-
tion standards. Operation of the power supply will be detailed in Default Mode unless otherwise specified.
Retrofit Mode
This mode is an alternative to Default Mode, to be used for legacy/existing installations
Note that when the power supply is configured for use in Retrofit Mode, the FACP should be monitoring either Input #1/Input #2 end-of-line
relay or the General Trouble relay, but not both.
In Retrofit Mode,
output
1 will blink as visual indication that the panel is operating in Retrofit Mode. Refer to Section
4 for details on LED
patterns.
Change Output Circuit Configurations Mode
1.
Enter this mode via the setting shown in Table 3.8. Once entered, the Output trouble LEDs will continually flash from right to left to
confirm the HPF-PS is in Change Output Configuration Mode.
2.
Configure settings on the Output DIP switches as needed (see Note above).
3.
Return to Default or Retrofit Mode via DIP switches settings for 9 and 10 as shown in Table 3.8 below. The output trouble LEDs will
stop the flash pattern described above to confirm Default or Retrofit Mode has been restored.

AC Fail/Ground Fault Indication
OFF
AC faults and ground faults are reported either by the Input #1 EOL relay or Input #2 EOL relay (if Input#1
is configured as sync) and by the General Trouble relay
ON
AC faults are reported only by the AC Trouble relay.
Table 3.7 AC Fail/Ground Fault Indication: Retrofit Mode
NOTE:
When switching between Default and Retrofit modes, go to Change Output Circuit Configurations mode first (and remain there for at
least 1 second) and then move to the desired new mode (even if nothing is changed in the DIP switch settings). This will ensure that the
operating mode is updated.
NOTE:
DIP switch settings may be changed to the desired configuration either before or after entering Change Output Circuit Configurations
Mode.
