Chapter 2 Warning Messages
Input IsoSwOpen 190 The input isolation switch is open when it is expected to be
closed. The switch should be closed in all operating modes of
the drive except System and Gate test. Be sure proper
positioning, wiring feedback to ACB, mechanical auxiliary
setup.
• In DC Current test modes, the isolation switches are expected to be
closed for DC Current test; although only the input contactor is
required the test will run with warnings if the switches are open.
• Be sure the isolation switches are in the proper position for the
specific operating mode (Refer to the description of the P141,
Hardware Option1 in the parameters manual).
• Verify wiring feedback.
• Verify isolation switch mechanical auxiliary setup.
Input IsoSwClsd 193 The input isolation switch is closed when it is expected to be
open. The switch should be open in System and Gate Test.
Ensure proper positioning, wiring feedback to ACB, mechanical
auxiliary setup.
Input Prot’n #1 74 Standard external fault/warning input included allowing the
end-user to install a protective relay (for example, input feed
protection relay) auxiliary contact that can activate a drive fault
or warning, depending on configuration of InputProt1 Class
(P440).
• See the associated fault description.
• Also check the 120V wiring and the XIO card.
Input Prot’n #2 78 Standard external fault/warning input included allowing the
end-user to install a second protective relay (for example, input
feed protection relay) auxiliary contact that can activate a drive
fault or warning, depending on configuration of InputProt2
Class (P444).
• See the associated fault description.
• Also check the 120V wiring and the XIO card.
InvHSnk Sensor 218 While Running, the drive has detected a missing temperature
sensor connected to the TFB on the inverter heatsink. A missing
sensor can result in either a Fiber Optic Loss fault or a Sensor
fault because a missing sensor can be interpreted as either 0° C
(32 °F) or over 100° C (212 °F), and both are unrealistic values.
• Verify sensor is completely seated properly on TFB.
• Measure sensor resistance.
• Replace if necessary.
• Ensure that the sensor in plugged in.
• NOTE: This is a warning because the drive should not fault on the
loss of the signal while running. There is no imminent danger to the
drive, but the user needs to be aware that there is a temperature
feedback signal missing.
Inv Gate PwrSup 213 This warning is for SGCT based drives and indicates a problem
with the gate power supply associated with a particular device
which is also likely in the warning queue.
• The device feedback was not correct due to power loss to the gate
driver board.
• This can be from the 20V DC output of the IGDPS or on the gate driver
board itself.
• This warning can also appear as a result of another device fault such
as an Online fault.
• This warning can also appear if the device has failed.
Invalid AlarmBit 98 DEVELOPMENT ERROR - An unused bit in the first 16 bits in
either a fault or warning word has been set and detected by the
alarm queue server. Either a used bit has been overlooked in
the faults/warnings database, or the control is incorrectly
setting an alarm word. Unused bit is being set in the fault or
warning word by the control software.
• Contact the factory.
