5.6.8.b Auto-Reset Programming (F052 – F054)
The TE Series can be programmed to automatically attempt a reset
based on the selected 'auto-reset' faults(F52), provided a Start
Command is present (see Section 4.2) and no fault condition is
active. Function F52 selects the 'Auto-Reset' faults and function F53
sets the number of reset attempts. If F053 is set to 0 (default setting),
the TE Series auto-reset function is disabled.

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 F052 = 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.
F052
Fault Condition Description
Setting
0 Auto Reset Disabled
1 Over Temperature Trip
2 Over Current (Shear Pin) Trip
3 Under Current Trip
4 Phase Loss Trip
5 Current Imbalance Trip
6 Ground Fault Trip
7 Short Circuit Trip
8 Faults 1, 2 or 3 above
9 Faults 4, 5 or 6 above
10 Any Fault except 7
11 Any Fault except 6 & 7
12 Any Fault above, 1 - 7
Note 1: UC, OC or UB require operation to resume before the fault can be detected.
Note 2: Cycling and / or restoration of control power will reset all of the above faults.
Note 3: Overload Trip reset function is programmed only in F005. See Section 3 for details
Note 4: Reset attempts with a fault condition present will cause a new fault. This will be logged
into the fault history (F085 – F093) and may overwrite previous fault records. Line Loss Trip (see
F051) will automatically reset and is not included in this list.
Table 5.6.8.b: Faults Selected for Auto-Restart
F053 = Auto-Restart Attempts
Factory Setting = 0 (Disabled)
Range = 1 - 10 Attempts, or 0 (Disabled)
If F053 = 1 through 10, the TE Series will attempt to restart if the
Start Command is present for this number of times. If F053 is set
to "Zero", the starter will not attempt to reset automatically.
