Testing The Main Control
If the main control is suspected of being faulty, the
following procedure should be performed to verify
main control for functionality.
Relay & DC Outputs
One of the primary functions of the main control is to
operate the multiple relay and DC outputs during
each cycle. Verify proper operation of these relays
using the following procedure.
1. Enter “Relay Toggle” through the service menu.
NOTICE
Frequently toggling the compressor relay could
force the compressor into overload. The
compressor will automatically deactivate during
an overload and will remain deactivated until the
overload switch cools. This could take some time.
It is important to allow the compressor at least 5
minutes off time between relay cycles.
2. Toggle the relay. Its related component should
activate / deactivate with the switching of the
relay. If it does not, test component.
Other Suspected Main Control Faults
If other components have been ruled out as being
faulty but the unit continues to have operating issues,
it is most likely due to a configuration error.
Configuration errors can be cleared by restoring the
unit to its factory default setting. Factory defaults
may be restored through the service menu.
CAUTION
Precautions must be taken while working with
live electrical equipment. Be sure to follow
proper safety procedures while performing tests
on live systems.
REED SWITCH
A reed switch is used to monitor door state. When the
door is closed magnetic force pulls the reed to its
contact and closes the circuit which turns the light and
display off. When the door is open the reed pulls away
from the contact and opens the circuit. If the door is
left open for longer than 5 minutes, the switch will
trigger an error code and set an audible warning.
