Error Codes and Audible Warnings
Whenever the E.A.H.S. system encounters a fault and/or a condition
outside of the normal operating parameters it will display an error code
and/or sound an audible warning. Use the following tables and
descriptions for further explanation.
If the E.A.H.S. system encounters a problem that results in an error
code, the system will shut down (unable to automatically track arc
height) and will display the code as follows. The red power L.E.D. will
flash once per second (1 Hz) until the error code is cleared by resolving
the cause of the problem. Depending on the type of error the flashing
red L.E.D. may be accompanied by an auditable beep(s). Error codes
are then read by interpreting the displayed sequence of the three (3)
yellow L.E.D.’s, they are read from top to bottom (see below).
ER 1, Main Stepper Communication error: communication between the main stepper
control microcontroller and the E.A.H.S. is malfunctioning. Consult your Gullco
representative.
ER 2, Slave Stepper Communication error: communication between the slave stepper
control microcontroller and the E.A.H.S. is malfunctioning. Consult your Gullco
representative.
ER 3, Remote pendant keypad #690 Communication error: communication between the
remote pendant keypad #690 control microcontroller and the E.A.H.S. is malfunctioning.
Consult your Gullco representative.
ER 4, Current Sensor board Filter #690 Communication error: communication between the
current sensor control microcontroller and the E.A.H.S. is malfunctioning. Consult your
Gullco representative.
ER 5, Remote pendant keypad #6627 Communication error: communication between the
remote pendant control #6627 microcontroller and the E.A.H.S. is malfunctioning. Consult
your Gullco representative.
ER 6, Stepper Board over temperature error: the temperature of the driver on the stepper
board, located inside the remote pendant, has exceeded 96°C or 205°F. The E.A.H.S. must
be powered down and allowed cool for a short period of time in order to reset this code.
