tions timeout
has occurred.
According to the A zero cross
operation at error has been
error setting detected.
According to the A heater burn-
operation at out has been
error setting detected.
According to the A heater over-
operation at current has
error setting been detected.
According to the An SSR short-

Correction
Cycle the power supply.
If operation does not recover, use the following
procedure, noting that all settings will be returned
to their default values.
• Error Response Received
Initialize the settings and perform a software
reset with an Operation Command.
• Error Response Not Received
Set the host data length, stop bits, and parity to
the default values for the G3ZA (if a Converter is
being used, set it to the same values) and then
initialize the settings and perform a software
reset with an Operation Command.
If operation still does not recover, the G3ZA
needs to be repaired.
• Check to see if the communications line is bro-
ken.
• Check to see if a communications error has
occurred.
• Check the host to see if it is functioning cor-
rectly.
• Check the information provided in 4-8 Detecting
Communications Timeouts (4 and 8-channel
Models) on page 48.
• Check to see if the load power supply's voltage
and frequency are within specifications. The
specified ranges are as follows:
Controllers with 100 to 240 V Load Voltage:
75 to 264 VAC
Controllers with 400 to 480 V Load Voltage:
340 to 528 VAC
Frequency (all models) : 47 to 63 Hz
• Noise may be a factor. Check the load power
supply line for noise and check the general area
around the G3ZA for noise.
• The heater has burned out. Repair the heater or
the heater line.
• Check the information provided in 4-5 Detecting
Heater Burnouts (4-channel Models Only) on
page 36.
• An overcurrent has occurred to the heater.
Return the current to the correct range.
• Check the information provided in Wiring Dia-
grams on page 12 and in 4-6 Detecting Heater
Overcurrent (4-channel Models Only) on
page 43.
• The SSR has short-circuited. Replace the SSR.
• Check the information provided in Wiring Dia-
grams on page 12 and in 4-7 Detecting SSR
Short-Circuits (4-channel Models Only) on
page 45.
