Appendix 4: Process Control Timer Functions 
 
F030 through F039; Overview of Process Timer Control and Time Clock Controller Features
The following special functions allow your TE Series starter to operate automatically from an internal Process 
Control Timer and Time Clock Controller (TCC) using a real time clock. The Process Control Timer (F030 and 
F031) can be used independently or together with the TCC feature (F032-39). The TCC requires using the 
Process Control Timer to provide for Start commands (depending on the selected mode). Time progression and 
clock values can be read in the Status Screen (see section 5.3.1).  
A convenient chart at the end of this appendix shows all settings and interactions. 
F030 =  Process Control Timer Selection 
Factory Setting = 0 (Disabled) 
Range = 0, 1, 2 
This function enables a Process Control Timer, which offers 
two operating modes (Minimum Batch Run Timer and 
Permissive Run Timer), selected by entering 1 or 2 here. 
 
F030 = 1: Minimum Batch Run Timer  
In this mode, the Process Control Timer engages that the 
motor will run for a minimum amount of time, regardless of 
whether someone stops it intentionally, or power fails and 
returns. When selected to Minimum Run Timer, it begins 
counting down after a Start command. The Time Value is set in 
F031. When the time value reaches [0000] the starter will turn 
off, even if the Start command is still closed and without a Stop 
command.  
 
To Reset the timer in this mode, give a Stop command after the 
timer has expired. If using the TCC (F032), reset is automatic 
when completed and no other Run command is present.  
 
If a Stop Command, power failure or Fault trip occurs during 
timed operation, the Process Control Timer is suspended and 
maintains its value. When the starter is then restarted, the timer 
resumes counting down to ensure that the motor has run for the 
programmed amount of time (finishes the batch).  
Use this function to ensure that a load operates for a minimum amount 
of time regardless of other circumstances. Examples would be:  
ƒ  Irrigation pumps where a specific amount of pumping time is 
required even if the pump is shut down on a low level alarm and 
then resets, or power fails and returns. 
ƒ  Mixers that need to agitate for a specific amount of time yet 
may be shut down when power fails or as product is added. 
ƒ  Aeration Blowers that must be run for minimum amounts of 
time to ensure that proper aeration (contact time) has been 
provided to a tank. 
ƒ  NOTE:  
In 2-wire control systems where the Run command is maintained, the 
starter will automatically restart after a power failure or a Trip is reset. 
Use appropriate warnings as mentioned in section 3.1.3.b  (see the 
following F032 description for an exception to this). 
In 3-wire control systems, a new Start command will be required to 
restart the starter.
