INS TRUCTIONS, AND TROUBLESHOOTING
The High h Batch oven continually monitors and logs fault conditions. For instructions on viewing the Fault Log, see page 24.
The Fault Log
οLogs each fault up to 255 instances before rolling back to zero.
οIncrements when a fault is detected, but does not decrement when the fault is cleared (whether through service or some other action).
Reference Figure 23 (below) to determine when (i.e., which oven state) a fault can occur.
F1: BLOWER (Blower Running Status Bad)
This fault will display when the Blower Motor Controller indicates no running status. The oven responds to this fault by terminating a Cook Cycle
and/or reverting to the Off State. The oven will automatically attempt to restart every 2 seconds until the fault is cleared.
To clear this fault:
1.Turn the oven on. The Control System may be able to successfully restart the Blower Motor.
2.Test the Blower Motor from the Test Mode Menu (for instructions, see page 24).
Troubleshooting this fault:
To troubleshoot an F1 Fault, see the diagram on page 18.
F2: LOW TMP (Cook Temperature Low)
This fault will display if the Cook Chamber temperature is more than 84°F (47ºC) below the set temperature after 5 seconds into a Cook Cycle.
To clear this fault:
Try cooking again. If the Cook Chamber temperature is within 84°F (47ºC) of the set temperature, the fault will clear.
Troubleshooting: F2 Fault
To troubleshoot an F2 Fault, see the diagram on page 19.
