Description
Use this signal to turn on output from
the user-remote interface. You must first
select ANALOG from the control panel
(or send Command 14 from a host
computer), which transfers control to
RMT ON.D. Momentary closure
between RMT ON.D and OUT COM.D
(pin 37) turns on output power provided
RMTOFF.D is connected to IN COM.D.
Pull this 0 to 15 Vsignal low to clear the
control panel lock code (reset it to zero).
The signal sinks 35 mA and is internally
pulled up to 15 V through a 10-k
resistor.
The pin 9 signal is a dedicated return for
all analog outputs.
All analog outputs from the MDXII unit
should be measured differentially from
this pins, which should be tied to the
system signal ground. The difference
between this ground and the MDXII
chassis ground should not exceed 3 V.
The pin 10 signal is a dedicated return
for all analog inputs.
All analog inputs from the MDXII unit
should be measured differentially from
this pin, which should be tied to the
system signal ground. The difference
between this ground and the MDXII
chassis ground should not exceed 3 V.
Use these signals to monitor the system
interlock string. If all the interlock
conditions (auxiliary, vacuum, and
water) are not satisfied either 1) the
main contactor will not close, or 2) if the
contactor is already closed, it will open
when the interlock string is interrupted.
