7.3.3. Test 3: EPC Field Test
This Output Analyzer test verifies that the acceptable activation current is being supplied by the EPC to the field
devices through series firing circuit field wiring. The Analyzer comes with jumpers and test leads that are used to
perform these tests. To get started:
1. Make sure the EPC is powered down
2. Disconnect and shunt all GCAs connected to the EPC's series firing circuit (P3-2).
3. Install a 1-Ohm Resistor (P/N E10-0174) (available separately) where the GCA leads are disconnected, except
at the field box under testing.
4. At the field box under testing, install short wire leads into the GCA firing circuit terminals.
5. On the first field box to be tested, use the 14-inch long leads and alligator clips supplied with the Analyzer to
connect the EPC output terminals to the GCA firing circuit on the first field box to be tested (see Figure 7.3.3-1
below).
6. Connect the 0Ω shunt to the Analyzer, as shown in Figure 7.3.3-1 above.
7. Power on the EPC.
8. Turn on the Analyzer, wait the three seconds for the battery charge status to flash, then press and release the
SELECT button to arrive at the EPC Tool menu (Option #1). Press the ENTER button to choose this option. The
following screens will briefly display:
