Model FL4000H
After 5-8 seconds of the Test Lamp flashing in Phase 3, the FL4000H goes into Phase 4,
indicating 1.5 mA (3.5 mA with HART and small HART current disabled) 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 FL4000H 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).
