4. PROGRAMMING THE CONTROLLER
The controllers are programmed by dipswitches and trimmers in the MAN
mode, or by setting the internal parameters - in MEM mode, accessible
via programming key or via serial line.
4.1 Manual and standard internal
parameter programming
The functions that can be set manually using the dipswitches and
trimmers (Fig. 4.aa) are shown in the tables below, complete with the
Modbus variables used to read the manual settings.

OFF: MAN: set fundamental parameters from FCR panel
ON: MEM: set parameters in internal memory
Dip S2.2 Select type of analogue inputs
OFF: 10V: 0/10 Vdc
ON: PWM: 0/5 Vdc or PWM
Dip S2.3 Select voltage/current input
OFF: V: Voltage signal (selected via Dip2)
I: Current signal (Dip2 must be ON)
Tab. 4.a
If dipswitch S2.1 is ON, the standard internal parameters are used,
equivalent to those that can be set on the panel. These have the same
name, however with the su x MEM rather than FCR.
