Operation
Power is supplied via the two removable power connectors which are retained by
screws and marked
L+A
,
MA
, and
L+B
,
MB
. Each has a LED to indicate the
presence of voltage over 15 VDC. The LEDs are marked
A POWER
and
B
POWER
. There is also a connector (
J3
) for a Power Monitor board used to indicate
the presence of both A and B power. See Section See Section 19,
Power Monitor
Board
(6ES7650-1BA02-0XX0).
Incoming power from
A
and
B
is diode OR’d, in
CR106
, to provide the MTA and
the module power from either input source. The output from
CR106
is sent to the
I/O modules via the module fuses and to the channels via the channel fuses.
Module Fuse 1 (
F100
) supplies the I/O Module plugged into
J1
and Module Fuse 2
(
F101
) supplies power to the I/O Module plugged into
J2
.
Each channel has an LED to indicate the presence of power, fuse, and disconnect
switch status. If there is no power, or the fuse or disconnect switch is open, then
the LED remains off. If there is power and the fuse is good and the disconnect
switch is closed, then the LEDs are illuminated.
Field Terminals, C (
CHx+
), Channel – (
CHx-
), and Shield (
SHx)
, connect
to the field devices.
CHx+
is the +24 VDC power feed and is fused (.05A) on a
channel-by-channel basis. The field termination connector is removable for ease of
wiring maintenance and is retained by friction.
The
CHx
- connects to the I/O modules input via
J1
and
J2
. Redundant operation
uses two modules with one each connected to
J1
and
J2
, while non-redundant
systems have one module connected to either
J1
or
J2
.

Installation Requirements
See Section 2,
, before performing any installation and observe all
warnings
Common interconnecting cables (6ES7922-3BD00-0AS0 and 6ES7922-3BJ00-
0AS0 and 6ES7 326-1BK02-0AB0), supporting the Failsafe Discrete Input
channels, interconnect the discrete input termination assembly to the 12/24-
channel, 24 VDC Failsafe Discrete Input module (6ES7 326-1BK00-0AB0, or 6ES7
326-1BK01-0AB0, E-Stand 1 or higher).
Note
To disconnect the interconnecting cable shield from ground at the MTA only, cut
and remove the shield disconnect jumper,
W100
and
W101
, for the associated
cable
13.5
Maintenance
See Section 3,
, before performing any maintenance and observe all
warnings
Under normal operation, the
A/B
Power LED
and the
Module 1/2 Fuse LED
are
on. If all are off, check the power supply to MTA. If the
A/B
Power LED
is off,
