for details regarding
error message display and manual clearing of error codes.
Power failure alarms can be enabled or disabled in the “Unit Start System Menu”. Use the
following procedure to enable or disable power failure alarms
. The “System Configuration Menu”
is located within the “Unit Configuration Menu (
see 6.3.Unit Configuration
). See
A.6.4.System
Configuration Menu
and
A.6.4.1.Unit Start System Menu
for more information regarding menu
navigation.
1)
From the “Unit Configuration Menu” rotate the current encoder until the display shows
“CFg” “SyS”, and then press the voltage encoder switch to enter the “System
Configuration Menu”.
2)
From the “System Configuration Menu” rotate the current encoder until the display
shows “SyS” “Strt”, and then press the voltage encoder switch to enter the “Unit Start
System Menu”.
3)
From the “Unit Start System Menu” rotate the current encoder until the display shows
“Strt” “P.FLt”, and then press the voltage encoder switch to view and change the power
failure alarm enable/disable setting.
4) The power failure alarm enable/disable setting is indicated by displaying
“Por FAIL FLt”
on the top display and the power failure alarm enable/disable setting in the bottom
display. The SET lamp is blinking on and off to indicate that a setting is displayed.
Rotate the current encoder to change the power failure alarm enable/disable setting.
Select “on” to enable power failure alarms. Select “OFF” to disable power failure
alarms. Once the desired configuration is selected press the voltage encoder switch to
accept the value and return to the “Unit Start System Menu”.
5)
From the “Unit Start System Menu” rotate the current encoder until the display shows
“Strt” “End”. Then press the voltage encoder switch to exit the “Unit Start System
Menu” and return to the “System Configuration Menu”.
6)
From the “System Configuration Menu” rotate the current encoder until the display

6.3.6. Remote Operate/Standby Control (Digital Input)
The inhibit input can be used as a digital input to remotely control the operate/standby state.
Since the inhibit input is connected to a hardware disable circuit the power supply will always go
into standby mode when the inhibit input disables the output.
It is possible to independently configure the actions taken when the inhibit input changes from a
hardware enable state (INHIBIT lamp is off) to a hardware disable state (INHIBIT lamp is on) or
from a hardware disable state (INHIBIT lamp is on) to a hardware enable state (INHIBIT lamp is
off).
