FL4000

•
After 5-8 seconds of the Test Lamp flashing in Phase 3, the FL4000 goes into Phase 4,
indicating 1.5 mA (3.5 mA with HART) at the analog output, changing the LED flashing to
indicate “Test Mode Running” shown in sequence #8 (Table 3).
•
After 4.25 minutes in Phase 4, the FL4000 returns to Ready Mode, indicating 4.3 mA at the
analog output, restoring the LED flashing to “Ready” shown in sequence #2 (Table 3).
NOTE:
After the test is initiated via wire or MODBUS; all other commands are ignored until the
Test Mode is over. While in Test Mode, the unit will not detect flames. Interruption of the
Test Lamp flashing for more than 3 seconds will result in termination of the test sequence
and a return to Ready Mode (Phase 0).
