C)
C)
Open collector signal, referenced to pin 11 (Signal Return). On when the output voltage
of FPS1000 unit "C” is higher than ≥ 80%+/-5%. The maximum sink current: 10mA
and the maximum external voltage is 15V.
Positive sensing. The +Sense signal should be connected to the positive terminal of
the load. The +Sense and -Sense leads should be twisted pair to minimize noise pick-
up effect. The maximum load wires drop compensation is 1V/wire.
Open collector signal, referenced to pin 11 (Signal Return). On when the input voltage
of FPS1000 unit "B" is ≥85Vrms. The maximum sink current is 10mA, and the maximum
external voltage is 15Vdc.
Turns the output of FPS1000 unit "B" to On and Off by electrical signal or dry contact
between pin 15 and pin 11 (Signal Return). 0~0.6V or Short: On, 2~15V or Open:
Off. The maximum source current is 2.6mA.
Open collector signal, referenced to pin 11 (Signal Return). On when the input voltage
of FPS1000 unit "A" is ≥85Vrms. The maximum sink current is 10mA, and the maximum
external voltage is 15Vdc.

Negative sensing. The -Sense signal should be connected to the negative terminal
of the load. The -Sense and +Sense leads should be twisted pair to minimize noise
pick-up effect. The maximum load wires drop compensation is 1V/wire.
Open collector signal, referenced to pin 11 (Signal Return). On when the internal temperature
of FPS1000 unit "C" is within safe limit, Off approx 10°C below Thermal shut down. The
maximum sink current is 10mA and the maximum external voltage is 15V.
Open collector signal, referenced to pin 11 (Signal Return). On when the input voltage
of FPS1000 unit "C" is ≥85Vrms. The maximum sink current is 10mA, and the maximum
external voltage is 15Vdc.
Turns the output of FPS1000 unit "C" to On and Off by electrical signal or dry contact
between pin 25 and pin 11 (Signal Return). 0~0.6V or Short: On, 2~15V or Open: Off.
The maximum source current is 2.6mA.
Current sharing signal. When FPS-S1U racks are connected in parallel, the CS pins
of the units should be connected to allow current balance between units.
Connection for output voltage trimming of FPS1000 unit "C". The voltage can be
trimmed within its range specifications.
Return for the following control and supervisory signals: On/Off, DC_OK,
Over_temperature Alarm, AC_Fail, Auxiliary 12V supply. The Signal return is isolated
from the output terminals.
