Parameter Description
INTERNAL /
EXTERNAL
Power module location: Internal to the master mainframe or
external to the master mainframe (residing in an expansion
mainframe, connected using a net cable).
E= Last known error code reported by the power module.
Setting the
re-
programming
delay
The reprogramming delay is a feature that eliminates false events due to output
transients.
What is reprogramming delay
When a change in the power module’s output is commanded (voltage, current, on ,
off etc.) transients in the output voltage and/or current may occur.
The power module’s controller can be programmed to ignore events caused by those
transients by defining a reprogramming delay period.
Whenever a change in the power module’s output is commanded, the module’s
controller initiates a reprogramming delay period during which it ignores changes in
operating conditions (such as current limit, window warning, OCP etc.).
The OVP mechanism is a hardware mechanism so it can not be
deactivated. During the reprogramming delay period the OVP
threshold is set to the maximum value (Vmax + 10%).
How to set the reprogramming delay
Select the power module.
The amount of reprogramming delay to use is set using the numeric entry keys:
Make sure the display is in setup mode.
Select the power module (move the cursor to the condensed status
symbol of the power module) using the LEFT / RIGHT selection keys.
Use one of the following methods to set a value for the reprogramming
delay:
o Enter a 3 digits value in units of 100 mS. Alowed range is 0 to 255
(0 to 25.5 seconds).
o Enter less then 3 digits and press ENTER.
o To set the value to the factory default, press the DEL key to clear
the value and then press the ENTER key.
Power
module
location and
selective
shutdown
Power modules can reside in the XMP’s master mainframe or in an expansion
mainframe. The system controller needs to know the location of the power modules
for calculating the mainframe’s total output power.
What is selective shutdown
When a power module reports a fault (such as OVP or OCP) it also shuts itself
down.
