SECTION 7: LABORATORY ACCEPTANCE TESTS
NOTE
Before performing any of the tests described in this section, be sure that you have read and un-
derstood the procedures in Section 6 of this manual. In particular, review the information on the
READ mode and PROGRAM mode. These modes will be used many times during the proce-
dures in this section
7.1 INTRODUCTION
This section contains procedures for testing two 9300 relays that are connected back-to-back. It is also possi-
ble to perform some tests on a single RFL 9300 that is communicating with itself (its transmitter connected to
its receiver). These single-relay tests will be described in Section 8 of this manual.
NOTE
Three terminal units are to be converted to two terminal operation for Laboratory
and Single Relay tests.
7.2 EQUIPMENT REQUIREMENTS
The following equipment is required to perform back-to-back testing:
1. A Volt-Ohm meter.
2. A dc voltage source capable of supplying either 48 Vdc or 125 Vdc, depending upon the power supplies
installed in the RFL 9300.
3. A dc current source that can provide at least 0.4 amperes to drive two 0.2A dc sense circuits.
4. A 60-Hz, single-phase ac current source that can supply up to 15 amperes.
5. The following item is required for 9300 relays equipped with modem modules:
a. Two twisted pairs of wire several feet long.
6. The following items are required for 9300 relays equipped with direct digital interface modules:
(See Figure 7-1)
a. An RFL DCE emulator (RFL part No. 105880).
b. A +5Vdc power supply for the RFL DCE emulator.
c. Two RS-449 cable assemblies used to connect the direct digital interface module to the
RFL DCE emulator (RFL part No. 302196-X or equivalent).
