Section 9: Global Signals
The CoolX Global Signals are available on the J1007 System Signal Connector.
*NU: Not Used or No Connection
AC Fail
The CoolPac AC Fail Signal indicates that the input voltage has failed or has dropped below
70VAC. The AC Mains Fail signal is controlled with an NPN transistor providing an unbiased
open collector that is available on the J1007 System Signal Connector via the collector on Pin
8 and the emitter on Pin 1 (Common).
There is a 390Ω
resistor in series with the collector for
current limiting. During normal operation the transistor is ON, when the input voltage is lost
or goes below 70Vac, the transistor is turned OFF at least 1mS before loss of output voltage
regulation.
The maximum collector voltage is 5V, and the maximum collector current is 12mA.
Refer to the implementation circuit and Table of logics at end of Section 9 for
recommendations for driving Logic Level circuits with open collector signal outputs.
Global Power Good
A Global Power Good signal is controlled with an NPN transistor providing an unbiased open
collector signal that is available on the J1007 System Signal Connector via the collector on Pin
5 and the emitter on Pin 1 (Common). This is activated when all enabled CoolMods report
individual Power Good for their outputs. Th
ere is a 390Ω resistor in series with the collector
for current limiting. When the output of ALL CoolMods are within 10% of Vset, the transistor
is turned on. When the output of any enabled CoolMod is >10% outside of Vset, the transistor
is turned off.
The maximum collector voltage is 5V, and the maximum collector current is 12 mA.
Refer to the implementation circuit and Table of logics at end of Section 9 for
recommendations for driving Logic Level circuits with open collector signal outputs.
