Example: Figure App 4.1 
Minimum Run (Batch) Timer 
 
An irrigation pump needs to come on when called for by a soil 
moisture control system, and run for ½ hour. If during that ½ 
hour the well level drops and shuts the pump down, the pump 
needs to restart when the well recovers and finish the ½ hour 
pump time. 
 
Set F030 to [0001] for Minimum Run Timer
This will ensure that when the well level recovers and resets 
the run command, the starter will finish the time sequence. 
 
Set F031 to [0030] (minutes) 
This is the Run Time that ensures the proper amount of 
irrigation getting to the crop. 
 
(Not Shown) 
 
Ensure F032 is set to [0000] for One Shot 
This will allow the Start command provided by the external 
control system to engage the starter at any time it is required. 
 
(Another example of this function used with the Time Clock 
Controller is provided further on) 
 
 
 
 
ƒ  NOTE on interaction with other functions: 
 
When used with F028 (Auto-Restart Delay), the Minimum Batch 
Timer will not resume counting down until F028 has expired and the 
starter has restarted. When used with 3 wire control, it may be 
necessary to maintain a Start Command until after F028 has 
expired, or repeat it if momentary. 
 
When used with F049 – F050 (Lockout Protection features), the 
Minimum Batch Timer will not resume counting down until those 
settings have been satisfied and the TE Series starter has 
restarted. When used with 3-wire control, it may be necessary to 
maintain a Start Command until after they are satisfied, or repeat it 
if momentary. 
 
When used with the Pump Flex Decel feature, the Decel Time 
(F027) is counted as part of the Batch Run time for this feature.
