3.8 CONTINUOUS OPERATION
1. 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 & highlighted.
2. The message “CONTINUOUS RUN MODE SELECTED” will be displayed in the MessageCenter for 10 sec-
onds.
3. The operation indication in the status bar will no longer be highlighted. The unit is now in Continuous Oper-
ation.
In Continuous Operation, the unit will not shutdown except in response to a shutdown alarm. Refer to Section 4.7
for more detailed information on Continuous Operation.
The control system may be configured with continuous operation tied to setpoint ranges for either frozen or perish-
able loads. The START-STOP/CONTINUOUS key is locked out if “CONTINUOUS LOCKED” displays in the Mes-
sageCenter when the key is pressed and the unit is in Continuous Operation or “START-STOP LOCKED” displays in
the MessageCenter when the key is pressed and the unit is in Start-Stop Operation. Refer to Section 5.2.3 for more
information on Configurations.
If the unit fails to start after three start attempts the A00031 - “FAILED TO START-AUTO” alarm will be activated.
While running, if the unit shuts down, an internal counter keeps track of the shutdowns. Should the unit shutdown
three consecutive times without running a minimum of 15 minutes between shutdowns the A00030 - “FAILED TO
RUN MINIMUM TIME” alarm will be activated. The shutdown counter is cleared when the unit has run for 15 min-
utes.
3.9 DATA RECORDER
The APX control system contains a built-in DataLink data recorder with 3 megabytes of memory. The recorded
data can be downloaded from the DataLink data recorder using either the TRU-Tech/TRU-View program or a Data
Transfer USB memory device.
The DataLink data recorder reads the same input information as the control system (Functional Parameters, Con-
figurations, and Unit Data) at all times. The DataLink data recorder records events as they occur, such as setpoint
changes and defrost initiation and termination, and also records all data values including temperature sensors and
pressure transducers in either averaged or snapshot format at selected intervals
The following intervals are available for sensor recording:
• 2 Minutes
• 5 Minutes
• 10 Minutes
• 15 Minutes
• 30 Minutes
• 1 Hour
• 2 Hours
• 4 Hours
