ALARM CODE TABLE:

COD. POSSIBLE CAUSE / DESCRITPION
OFF Remote stand-by active (digital input)
EEPROM ALARM
An error was found in the EEPROM
E0 memory.
(The outputs are all disabled apart from the
alarm outputs)
EEPROM 100N MASTER ALARM
An error was found in the EEPROM memory
E0n
of the 100N MASTER3. (The outputs are all
disabled apart from the alarm outputs)
Operation anomalies of the intake pressure
E1
probe (compressor outputs disabled)
Operation anomalies of the delivery
E2
pressure probe (fan outputs disabled)
Maximum pressure general alarm, from
EH digital input (compressor outputs are
disabled, fan outputs remain unchanged)
Minimum pressure general alarm, from
EL
digital input (all outputs are disabled)
Maximum intake pressure alarm
EHc
(compressors outputs remain unchanged)
Minimum intake pressure alarm
ELc
(compressors outputs disabled)
Maximum delivery pressure alarm
EHu
(compressor outputs are disabled, fan
outputs remain unchanged)
Minimum delivery pressure alarm
ELu
(fans outputs disabled)
Central pre-alarm in manual mode.
E7
This alarm does not change the status of the
outputs.
Central alarm in manual mode.
It is triggered after 5 interventions in the
E8
(Nip) time of its digital input ("central alarm
in manual mode").
(The outputs are all disabled apart from the
alarm outputs)
EC1
EC2
Protection of one or more compressor
EC3
outputs (e.g. Thermal protection or max.
...
pressure switch.)
(The output of the relative COMPRESSOR
EC8
is deactivated)
EC9
EC0
