Troubleshooting cont.
Error 5
The controller has detected that the CABINET TEMPERATURE IS NOT COOLING AS
EXPECTED. Likely causes are leaving the cabinet door open for extended periods of time
during operation or the power was left on while defrosting the cabinet. Other possible
causes are a restriction to the air flow across the condensing unit such as might occur with a
dirty or plugged condenser filter and/or coil, an improperly positioned temperature probe or a
malfunction of the refrigeration compressor. Check for obstructions near the condensing
unit inlet grill and inspect and clean the condenser filter and/or coil if needed. (

)
Verify the temperature probes are in place and properly secured to their mounting brackets.

Errors 6
The HIGH PRESSURE SWITCH FOR THE REFRIGERATION SYSTEM HAS TRIPPED.
Possible causes include a restriction to the air flow across the condensing unit such as
might occur with a dirty or plugged condenser filter and/or coil. Check for obstructions near
the condensing unit inlet grill. Inspect and clean the condenser filter and/or coil if needed
(
page 40
). A failed refrigeration over pressure switch, or a loose wire to the over pressure
switch could cause this error. A failed feedback relay or a loose wire to the feedback relay
can cause this error. Finally a very short duration power outage can case this error. CALL
OUR TECHNICAL SUPPORT HOTLINE FOR ASSISTANCE.
(WARNING: HIGH
VOLTAGE. Unplug the dispenser before attempting to repair the wiring for the high
pressure switch.) † (see note below to reset error)
Errors 7
The controller has detected an ERROR ON THE REFRIGERATION RELAY DRIVE
indicating the compressor feedback relay did not turn off when the controller turned off
refrigeration. This could be caused by a stuck refrigeration relay, the feedback relay stuck
shut, a short circuit, or controller output failure. Verify there is no foreign material or loose
connections around the relay output.
† (see note below to reset error)
Error 8
The controller has determined an INPUT FROM THE CABINET OR REFRIGERATION
CONTROL TEMPERATURE PROBE IS OUT OF RANGE HIGH OR LOW. The most likely
cause is a failed or disconnected temperature probe. Verify the temperature probes wires
are properly secured at the controller board.
Error 9
NVRAM CHECKSUM ERROR. The controller has detected invalid or corrupt data.
It is
normal to get this error the first time a dispenser is powered on after a new processor
has been installed or replaced
. The data may be invalid for several reasons. The
processor writes the permanent data (error logs, configuration, and operating parameters)
along with extra data that it uses to verify the data is valid. If the error persists it likely
indicates a failure of the NVRAM. CALL OUR TECHNICAL SUPPORT HOTLINE FOR
ASSISTANCE.
Error 10
An INTERNAL SYSTEM ERROR HAS OCCURRED. This error could occur for various
reasons including electrical interference, an error in the dispensers software or a fault in the
processor. CALL OUR TECHNICAL SUPPORT HOTLINE FOR ASSISTANCE.
