LED Display and LCD Screen Problems
Table 1. Error messages on the LCD display.
Error Message
Meaning
[Volt Sensor Err]
The voltage sensor is reading outside of its range or
may be faulty .
[Temp Sensor Err]
The temperature sensor is reading outside of its range
or may be faulty .
[Neutral Sens Err]
Neutral sensing controls only . This message is
displayed before the control locks out the bank following
a neutral current or neutral voltage alarm .
[NeutSens Lockout]
Neutral sensing controls only . The level of neutral
current or neutral voltage has caused the control to lock
out the bank .
[HiLoVoltBand Err]
The
Bank Voltage Margin setpoint is greater
than the difference between the High Voltage Override
Value data and the Low Voltage Override Value data .
[HiLoVoltLockout]
The control has locked out the bank because of the
high/low voltage band error .
[ZeroNeut SensErr]
Neutral sensing controls only . The control detected zero
neutral current or neutral voltage for the length of the
Zero Neutral Detection setpoint .
[Load Fuse Alarm]
The load fuse on the faceplate has blown .
A blown load fuse will be alarmed by all wiring options
except “-J67 .” For “-J67” any type of station power, even
dc, could be used as wetting voltage, so the sensing
input is wired to control power, and will not go off if the
load fuse is blown . For all other wiring options the sens-
ing input is wired to the load side of the load fuse, and
the alarm will be set for a blown load fuse .
