Status and Control
Some functions have two means of monitor/control; A
signal level that represents the analog value being
measured or controlled, or, reading/writing via the i
2 C
port the measured value or the control command.
Unless otherwise noted, control via the signals pins is
‘active’ so long that a firmware based command is not
initiated. Once firmware initiates a command that is also
represented on a signal pin, the firmware takes over and
replaces the hardware based control signal. Firmware
control is maintained until bias power to the processor is
interrupted. Once bias power is removed the processor
resets and the analog signal pin control is ‘active’ until
firmware takes over control.
Details of analog controls are provided in this data sheet
under Signal Definitions. GE Energy will provide separate
application notes on the I2C protocol. Contact your local
GE Energy representative for details.
Signal Definitions
All signals and outputs are referenced to Output return.
These include ‘Vstb return’ and ‘Signal return’.
Input Signals
Voltage programming (V
prog
): An analog voltage on this
signal can vary the output voltage ± 10% from 21Vdc to
29Vdc. The equation of this signal is:
V
out
= 21 + (V
prog
* 3.2) 0 < V
prog
< 2.5
If 2.5 < Vprog < 3, the output is 29V. If Vprog is > 3V or
left open the programming signal is ignored and the unit
output is set at the setpoint of 24Vdc.
Load share (Ishare): This is a single wire analog signal
that is generated and acted upon automatically by power
supplies connected in parallel. The Ishare pins should be
tied together for power supplies if active current share
among the power supplies is desired. No resistors or
capacitors should get connected to this pin.
Remote ON/OFF: Controls the presence of the main
24Vdc output voltage. This is an open collector, TTL level
control signal. This signal needs to be pulled HI
externally through a resistor. Maximum collector voltage
is 12Vdc and the maximum sink current is 1mA. A Logic
1 (TTL HI level) turns ON the 24Vdc output, while a Logic
0 (TTL LO level) turns OFF the 24Vdc output.
A turn OFF command either through this signal (Remote
ON/OFF) or firmware commanded would turn OFF the
24V output.
Enable: This is a short signal pin that controls the
presence of the 24Vdc main output. This pin should be
connected to ‘output return’ on the system side of the
output connector. The purpose of this pin is to ensure
that the output turns ON after engagement of the power
blades and turns OFF prior to disengagement of the
power blades.
Write protect (WP): This signal protects the contents of
the EEPROM from accidental over writing. When left
open the EEPROM is write protected. A LO (TTL
compatible) permits writing to the EEPROM. This signal
is pulled HI internally by the power supply.
Output signals
Output current monitor (Imon): A voltage level of
0.1V/Amp proportional to the delivered output current is
present on this pin. Accuracy: ± 500mV for loads > 25%
FL.
