Code/Fault
Indications
Drive Error!
Keypad stuck
Indicates that one of the interface buttons has been pressed for
more than 2 minutes, and that the interface may need to be
replaced. With power off, press the buttons repeatedly to attempt
to unstick.
Drive Error!
DC Voltage low
Indicates that the DC bus voltage has dropped below 230 VDC
and pump stops. Check incoming line voltage
(page 6)
and verify
that it is within 10% of pump rated voltage.
Drive Error!
DC Voltage High
Indicates that the DC bus voltage has risen above 400 VDC and
pump stops. Verify that line voltage is within 10% of pump rated
voltage.
Drive Error!
Motor phase lost
Indicates that one of the motor phases is open and that the motor
may need to be replaced.
TriStar VS is connected to
a GL/Hayward control.
Control reads “Pool
bridge comm
”
This indicates interference on the comm. ground between the
control and TriStar VS. This is caused by frequency noise emitted
from the pump drive. It travels on the comm. ground and AC
ground wire and interferes with the commands being sent from
the control.
