Warning/Alarm
Description
Cause
Remedy
46 — Power card supply
The supply on the power card is out of
range.
There are three power supplies
generated by the switch mode
power supply (SMPS) on the
power card: 24 V, 5 V, +/- 18 V.
When powered with 24 VDC with
the 24VDC Backup Option Card
option, only the 24 V and 5 V
supplies are monitored. When
powered with three-phase mains
voltage, all three supplied are
monitored.
Check for a defective power cord.
Check for a defective control card.
Check for a defective option card.
If a 24 VDC power supply is used,
verify proper supply power.
47 — 24 V supply low
The 24 V DC is measured on the
control card.
The external 24 V DC backup
power supply may be overloaded.
Contact your Xylem supplier.
48 — 1.8 V supply low
The power supply is measured on the
control card.
The 1.8 V DC supply used on
the control card is outside of
allowable limits.
Check for a defective control card.
If an option card is present, check for
an overvoltage condition.
49 — Speed limit
When the speed is not within the
specified range in [4–11] Motor Speed
Low Limit [RPM] and [4–13] Motor
Speed High Limit [RPM], the frequency
converter will show a warning.
When the speed is below the
specified limit in [1–86] Trip
Speed Low [RPM] (except
when starting or stopping) the
frequency converter will trip.
50 — AMA calibration failed
Contact your Xylem supplier or Xylem
Service Department.
51 — AMA check Unom and
Inom
The settings for motor voltage, motor
current, and motor power are wrong.
Check the settings in parameters
1–20 to 1–25.
52 — AMA low Inom
The motor current is too low.
Check the setting in [4–18] Current
Limit.
53 — AMA motor too big
The motor is too big for the AMA to
operate.
54 — AMA motor too small
The motor is too small for the AMA to
operate.
55 — AMA Parameter out
of range
The parameter values of the motor are
outside of the acceptable range. AMA
will not run.
56 — AMA interrupted by
the user
The AMA has been interrupted by the
user.
57 — AMA timeout
Try to restart AMA again. Repeated
restarts may overheat the motor.
58 — AMA internal fault
Contact your Xylem supplier.
59 — Current limit
The current is higher than the value in
[4–18] Current Limit.
Ensure that motor data in parameters
1–20 through 1–25 are set correctly.
Possibly increase the current limit.
Be sure that the system can operate
safely at a higher limit.
60 — Pump Protect
A digital input signal is indicating
a pump protection external to the
controller is active.
