6.3.2 START-UP PROCEDURE FOR A THREE-TERMINAL INSTALLATION
The following procedure is used to start up an RFL 9300 three-terminal installation. One RFL 9300 can be in-
stalled at each terminal end of a three-terminal line, or three units can be located side-by-side in a laboratory.
The terminals are referred to as local, remote 1 and remote 2.
NOTES
It is possible to start up a single RFL 9300 that is communicating with itself (with its transmitter
connected to its own receiver). This procedure is described in Section 8 of this manual.
As an option a three-terminal installation can have the addressing feature disabled by setting
the local, remote 1 and remote 2 addresses to “0000”. See paragraph 6.6 for more information.
The waiting times listed in the following procedure are for RFL 9300s equipped with modems.
Some of these waiting times will be much shorter for units equipped with direct digital or fiber
optic modules.
The terms “local”, “remote 1” and “remote 2” are only relative to the location of the operator. The
location of the operator is defined as the “local” terminal.
Perform all steps in the following procedure in the order presented.
1. Verify that all rear panel wiring was done according to the diagrams and information in Section 5 of this
manual. If the RFL 9300 is equipped with fiber optic modules, make sure the fibers are also properly
connected.
2. Establish voice communications between the local terminal and the remote 1 terminal, and between
the local terminal and the remote 2 terminal.
3. Verify that the system configuration jumpers on each of the three Supervisor Modules (93A SV) are set
to the desired positions as applicable (1A or 5A, 50 HZ or 60 HZ, and 3T). The configuration jumpers
can be viewed by the user by unscrewing the two captive thumbscrews on the RFL 9300 front panel
and then lowering the panel to its full opened position. The Supervisor module is the fifth module from
the left. More information on the Supervisor Module is provided in Section 10.
4. The POWER switch is located on the power supply module on the front right side of the RFL 9300
chassis. Open the front panel as described in step 3 to gain access to the POWER switch. Turn on the
local
RFL 9300 by placing the POWER switch on the power supply module to the ON (up) position,
and observe the following:
a. All three indicators on the front of the power supply will light, indicating that the power sup-
ply is functioning normally. The words "Please Wait" will appear on the display. Red alarm
indicators on the 93A SV and 93A PC modules will light, and the beeper will sound. The
front panel can now be closed.
b. The beeper can be shut off, if desired, by entering the PROGRAM mode and disabling pa-
rameter #44 (audio beeper enable/disable) as described in para. 6.4.4.
c. A green light will illuminate on the display controller (EN/GN = enable/green). This means
that trip is enabled.
d. After a few seconds, the word "ALARM" will flash on the top line of the display, and typically
the numbers "16 or 17", “34 or 35” and "46" will appear on the bottom line. The numbers
may be different due to factory test settings. (A complete list of alarm codes appears in Ta-
ble 6-4 of this section.)
e. The local RFL 9300 will remain in this state as long as the remote 1 and remote 2 termi-
nals are turned OFF, and as long as the local terminal, and remote 1 and remote 2 termi-
nal addresses have not been programmed.
