16.3
Operation
Power is supplied via the removable power connector marked
L+A
,
MA
, and
L+B
,
MB
. Each has a green LED to indicate the presence of voltage over 15 VDC. The
case of polarity reversal of the power supply is indicated by the LEDs illuminating
red. The LEDs are marked
A POWER
and
B POWER
.
Incoming power from
A
and
B
is diode OR’d to provide the MTA and the module
power from either power source. The output from the dual diode is sent to the I/O
modules via the module power fuses.
An onboard Power Monitor System (PMS) is used to provide an isolated dry
contact when redundant power is supplied to MTAs. Only when power is supplied
to both power inputs the output contacts
1
and
2
are closed. The Power Monitor
System is designed to detect only the presence or absence of power. It is not
designed to detect supply voltage which is outside the specification threshold.
