output on pin4 of both DC supply connectors of the console, illuminating
the ”POWER ALARM” LED on the front panel of the Redundancy PSU.
The power alarm output is a relay contact (max. 40 V/200 mA). Its
behaviour depends on jumper J1 on the PSU sub board (see component
layout diagram in the circuit diagrams chapter).
Pin4 is normally floating, and pulled to GND if alarm is active (P8 and P9
connected, default factory setting), or pin4 is normally pulled to GND and
becomes floating if alarm is active (P7 and P8 connected).
Note: It is recommended to leave the jumper setting as it is. If it is changed, the
POWER ALARM LED on the front panel of the 19” supply unit will be
illuminated if everything is alright, and vice versa.
Power-Down Should the supply voltage drop below 21.6 V, the console automatically
shuts down after having stored all relevant data.
A supply voltage of min. 22.0 V is required for correct start and operation
of the console.
Pin Assignment “ 24 V A” and “24 V B” connectors on the supply unit (10pin, female)
“ 24 V A” and “24 V B” connectors on the console (10pin, male).

Single Supply for Red. Version If only one 24 V
DC
supply should be connected to an OnAir 1000
Redundant Supply Version, this supply must be connected to the console’s
“24 V A” connector. In such a case, a bridge from pin6 (PSS1) to pin7
(GND) must be inserted in the female 10pin 24 V
DC
connector. It is
recommended to insert this bridge in a second 10pin connector plugged to
the console’s “24 V B” connector.
Even if there is only one 24 VDC supply, the secondary switchers are still
doubled for redundancy.
