Menu Guard Functions
NOTE: An access code is required to enter the
Guard menu to prevent unauthorized personnel from
tampering with the programmable features.
The Guard menu is used to set many programmable features
including:
• Unit Configuration
• Customer Configuration
• Container Identification Number
• Unit Serial Number
• Date and Time
• Unit and Special Hourmeters
• Economy Mode ECMAX and ECMIN
• Change Temperature Display Units (C/F)
• Sensor Grades
The controller turns OFF all control outputs and suspends
normal operation when the Guard menu is entered.
When the Guard Menu is exited, the controller resets and
then restarts the unit. This is necessary to be certain that all
changes in the programmable features are activated.
