INDICATION
On Off MODULE OK
Module and transducer are operating properly.
On Flashing TRANSDUCER FAULT
Transducer not operating properly. There are 6 major causes of
this fault.11
hýBroken or intermittent transducer cable
hýNon-compatible transducer
hýImproper wiring of the transducer cable
hýImproper installation of the transducer cable
hýFaulty transducer
hýFaulty module
Transducer faults are self clearing. If a fault is caused by a burst of
electrical noise or an intermittent connection, the fault will clear
itself.
Off On MODULE FAULT
The parameters in nvRAM are corrupted. Cycle power to the
module. If the fault clears, parameters will be set to default values.
If the fault does not clear then module must be returned to AMCI
for repair.
Note: If parameters are reset to their defaults on every power up,
the battery in the module may be discharged. If this is the case, the
module must be returned to AMCI for repair.
Off Flashing REFERENCE ERROR
The module stores constants in nvRAM to automatically adjust the
reference voltage. This display occurs if these constants are
corrupted. Attaching a working transducer should clear the fault.
If it does not, or the reference error occurs at every power up, the
module must be returned to AMCI for repair.
Flashing Off ADJUSTING REFERENCE VOLTAGE
This display occurs while the module is recalculating the reference
voltage constants (see Reference Error above). Once the constants
are recalculated the module’s LED pattern will display MODULE
OK or REFERENCE ERROR. If this display does not appear
when a working transducer is attached to clear a Reference Error,
the module must be returned to AMCI for repair.
