Auto-Reset Programming (F052 – F054)
The TE Series can be programmed to automatically attempt to
reset after selected faults, provided a Start Command is present
(see Section 4.2) and the fault condition has been corrected. The
Fault Events to attempt restarting (F052) and number of reset
attempts (F053) are programmable as follows. If F053 is set to 0
(default setting), the TE Series will not attempt to restart
automatically.
NOTE:
When using 3 wire control:
For safety reasons the TE Series will not attempt restarting unless
the Start Command is reinitiated and maintained during a restart
attempt.
F052 = Auto-Reset Selected Faults
Factory Setting = 0 (Disabled)
Range = 1 - 12, or 0 (Disabled)
If F053 = 1 through 12, the TE Series will attempt to restart
after the fault(s) coded in the following table. Only one selection
can be entered.

1. NOTE 1: UC, OC or UB require operation to resume before the fault can be detected.
2. NOTE 2: Cycling and / or restoration of control power will reset all of the above faults.
3. NOTE 3: Overload Trip reset function is programmed only in F005. See Section 3 for details
4.
NOTE 4: Reset attempts that occur when the fault condition is still present will cause a new
fault. This will be logged into the fault history (F085 – F093) and may overwrite previous fault
records.
5.
Line Loss Trip (see F051) will automatically reset and so is not included in this list.
Table 5.6.9.b: Faults Selected for Auto-Restart
F053 = Auto-Restart Attempts
Factory Setting = 0 (Disabled)
Range = 1 - 10 Attempts, or 0 (Disabled)
If F052 = 1 through 10, the TE Series will attempt to restart if
the Start Command is present for this number of times. If set to
Zero, the starter will not attempt to reset automatically.
