External CPU/Hardware Fail Alarm Connections
The external CPU/hardware fail alarm connections are made to
terminal block J4 located on the CPU circuit card installed in the
586505000/586505500 LMS1000 Main Cabinet or
582140000/582140001/582126100 Primary Power Bay.
Recommended wire size is 22 gauge for loop lengths up to 200
feet, and 18-20 gauge for loop lengths over 200 feet. Stranded
twisted pair wire is recommended. To minimize voltage potentials
inside the cabinet during installation, alarm relay leads should be
connected at the cabinet or bay first. Refer to Figure 7 or Figure 8
for terminal block location.
These leads enter the 586505000/586505500 LMS1000 cabinet at
the rear of the cabinet and are routed through a cable channel
located on the bottom of the cabinet.
• Terminal block J4 consists of two pieces snapped
together. The two pieces can be separated by gently
pulling the one half from the other. This feature
facilitates circuit card wiring and circuit card
replacement, if required.
• Wires are connected to the terminals of J4 by inserting
the stripped wire into the wire opening, and then
tightening the screw. The wires should be checked for
proper installation by gently attempting to pull the wires
from the terminal.
• Terminal block J4 accepts a wire size in the range of 28 to
16 gauge. Recommended torque is 4 in-lbs.
PROCEDURE:
1.
586505000/586505500 LMS1000 Main Cabinet: To
access terminal block J4 located on the Main Cabinet CPU
circuit card, rotate the two captive fasteners on the front
of the cabinet until the arrow on the fastener points up or
down, and pivot the door open.
or
582140000/582140001/582126100 Power System:
Open the front door of the Primary Power Bay to access
the LMS Main CPU circuit card.
2. Connect the external CPU/hardware fail alarm to
terminals 4 through 6 of J4. An open loop circuit is
provided between terminals 4 and 5 of J4, and a closed
loop circuit is provided between terminals 5 and 6 of J4
during a CPU/hardware fail alarm condition.
3.
586505000/586505500 LMS1000 Main Cabinet: If no
more connections are to be made inside the cabinet,
close the cabinet door and secure with the two captive
fasteners (arrow on fastener points towards outside of
cabinet).
or
582140000/582140001/582126100 Power System: If
no more connections are to be made inside the bay, close
the front door.
Local Terminal Port Connections
586505000/586505500: The local terminal is connected to the 9-
pin female D-type jack located on the front of the Main Cabinet,
labeled "RS-232". Refer to Figure 7 for jack location. Refer to Table
1 for jack configuration. This jack is configured as a DCE (Data
Communication Equipment).
Note:
When 586505000/586505500 List 88 is ordered, the port on
the front of the 586505000/586505500 cabinet is inactive,
and the local port is redirected to OEM1 located on the rear of
the cabinet. List 88 cannot be used in conjunction with
586505000/586505500 List 79 (Gateway Port), List 85 (AC
Analyzer Interface), or List 86 (TL1/X.25).
582140001/582126100: A 9-pin female D-type jack (labeled
"RS-232") is provided on the front door of the Primary Power Bay
(on the MCA Control Panel) for LMS local terminal connection.
Refer to Figure 8 for location. Refer to Table 1 for jack
configuration. This jack is configured as a DCE (Data
Communication Equipment).
582140000: The 9-pin female D-type jack (LMS RS-232 Local Port)
provided in the system wiring harness is factory connected to a
USB to RS-232 Port Adapter Unit. The USB to RS-232 Port Adapter
Unit is factory connected to the USB port provided on the front
door of the Primary Power Bay (on the MCA Control Panel) for LMS
local terminal connection. (A device driver CD is supplied with the
USB to RS-232 Port Adapter Unit. The proper driver must be
installed on the computer to be connected to the USB port.)
Note:
If required to connect to a serial port, disconnect the factory
RS-232 jack from the “USB to RS-232 Port Adapter Unit” and
connect to this jack. Refer to Table 1 for jack configuration.
This jack is configured as a DCE (Data Communication
Equipment).
