Programmer functions

9.1 Hold function

This function allows to interrupt a cycle: red display visualizes hoLd and cycle is
stopped. It is possible to modify setpoint pressing
To start this function proceed as follows:
• Enter configuration and select en. on parameter 17 HLd.f .
• With cycle in progress press

9.2 Automatic Tuning

This procedure allows the user to have a precise regulation also without knowledge
of PID regulation. Selecting auto on parameter 06 tune , controller check process
oscillations and modifies PID parameters if the difference between process and
setpoint values is greater than value on parameter 53 m.G.tu.
Parameters 53 m.G.tu. , 54 mn.p.b. , 55 ma.p.b. and 56 mn.i.t. can be modified
entering the password 5678.
