Continuous Operation
How to enable continuous run mode on the X4-7700
With the system powered up (START/RUN-OFF switch in the START/RUN position) or in PC mode, press the START-STOP/CONTINUOUS key until "CONTINUOUS" is displayed and highlighted.
The message "CONTINUOUS RUN MODE SELECTED" will be displayed in the MessageCenter for 10 seconds.
The operation indication in the status bar will no longer be highlighted. The unit is now in Continuous Operation.
In Continuous Operation, the unit will not shut down except in response to a shutdown alarm.
The APX Control System may be configured with continuous operation tied to setpoint ranges for either frozen or perishable loads. Refer to Section 5.2.3 for more information on configurations.
If "CONTINUOUS LOCKED" displays in the MessageCenter when the START-STOP/CONTINUOUS key is pressed, the unit is locked in Continuous Operation. If "START-STOP LOCKED" displays, the unit is locked in Start-Stop Operation. The key will not change the mode.
If the unit fails to start after three start attempts, alarm 00031 (Failed to Start - Auto Mode) will be activated.
If the unit shuts down three consecutive times without running a minimum of 15 minutes between shutdowns, alarm 00030 (Failed to Run Minimum Time) will be activated. The shutdown counter is cleared when the unit has run for 15 minutes.
