Appendix B: Summary of Error Messages
E1
MIN
INT
is caused by a Low-Level fault with a Low-Level
Switch connected to the pump. The pump is stopped
and the alarm outputs are activated. This operates in all
Internal and External modes. The pump automatically
restarts when the fault is cleared.
E2
FLOW
INT
indicates that the pump has lost prime. Again, the pump
is stopped and output alarms activated. Item 4 in the
Advanced Menu must be disabled (set to 0), it is not
usable with the HH9 pump.
E3
MIN
EXT
:
is displayed in the External mode if the stroke rate
exceeds 100 SPM. The pump is NOT stopped and NO
alarm outputs are activated with this fault. To stop E3
flashing, clear the fault condition, then stop and restart
the pump.
E4
EXT
X
is displayed in the External X (Batch) mode in two
situations. 1) If "Batch Accumulate" is disabled and a
pulse signal is received while the pump is counting
down. The pump is not stopped, and the alarms are not
activated. To clear the E4 message, the pump must be
stopped and restarted. 2) If "Batch Accumulate" is
enabled and the cumulative batch value exceeds 999, E4
will be displayed. The E4 message can only be cleared
if the pump is stopped and restarted.
E5
FLOW P12
EXT is displayed in the mA External mode if the mA input
value exceeds 21.0 mA, whether the pump is running or
stopped. Again, the alarms are NOT activated. Once
the mA signal goes below 21.0 mA, the E5 error
message is cleared.
