Error Message Explanation
“Low Pressure Too High!"
The low side helium pressure is above the high set point; release
helium from the system, verify line orientation (lines may be
reversed High to Low.)
"Delta Pressure Too High!"
The differential pressure is above the high set point; verify static
pressure.
"Delta Pressure Too Low!"
The differential pressure is below the low set point verify static
pressure; verify line orientation (lines may be reversed High to Low.)
"Static Pressure Too High!"
The static pressure is above the high set point; verify static
pressure, release helium
"Static Pressure Too Low!"
The static pressure is below the low set point; verify static pressure,
add helium
"Water In Temp Too High"
The inlet water temperature is above the high set point; reduce
water temperature
"Water In Temp Too Low"
The inlet water temperature is below the low set point; increase
water temperature
“Water Out Temp Too High!”
The outlet water temperature is above the high set point; increase
water flow rate and/or reduce temperature.
"Water Out Temp Too Low"
The outlet water temperature is below the low set point; increase
water temperature.
“Helium Temp Too High!”
The helium gas temperature is above the high set point; check
cooling water flow rate/temperature, check compressor module oil
level by checking sight glass when the helium compressor package
is running.
“Helium Temp Too Low!"
Helium discharge temperature below the low set point; check
cooling water temperatures, increase ambient temperature if
system has been off and ambient temperature is below 40 °F
“Oil Temp Too High!”
The oil temperature is above the high set point; check flow rate and
inlet temperature of cooling water.
“Oil Temp Too Low!"
The oil temperature is below the low set point; check cooling water
temperatures, increase ambient temperature if system has been off
and ambient temperature is below 40 °F (4.4 °C)
“Compressor Motor Current
Too Low!”
This occurs when the compressor module motor current is below
threshold while the motor is requested running. Can be caused by
an overheated compressor module.
“You have had 6 errors in
less than an hour: MM:SS”
The helium compressor package is in lockout mode due to more
than 6 errors within one hour; the compressor cannot be started
until 30 minutes has elapsed, and the lockout has been reset using
the reset button. MM:SS indicates minutes : seconds remaining
until helium compressor package can be restarted
“3 Phase Power Improperly
Wired!”
The order of the phase power is wrong. Re wire the input to the
helium compressor package by switching any 2 of the 3 input power
wires.
"Power Supply Error!"
Power supply has exhibited a fault, verify voltage output or contact
