5.7 Programming function
The programming function (which may be enabled selecting
on parameter 27 ) allows to perform a short 3-
steps cycle as in the diagram below (two rising steps, holding of
temperature for a fixed time, natural/uncontrolled cooling).
The controller reaches setpoint 1 following the gradient entered
on parameter 25
, then it reaches setpoint 2 with
maximum power. When process value reaches setpoint 2, the
temperature is hold for the time selected on parameter 26
. At elapsing of this time, the relay is switched off (0%
output) and display visualizes ; at next starting, the
controller will repeat this function.
** This function excludes alarm operating.
5.8 Function HOLD
This function (which can be enabled selecting on
parameter 27 ) allows to stop the reading of sensor input
when digital input is active, which means when pins 3 and 2 are
shortcircuited. As long as reading of sensor is stopped, display 1
will keep on flashing.
This function is NOT AVAILABLE for PT100 and NI100.
Attention: This function will slow down the sampling frequency
(for input V,mV, mA with filter set to 1, sampling will be 2Hz).
