(FG Configuration of Operating Modes
Switching mode from Manual to
Automatic
0 The setpoint is set to the same value as the variable and does not
cause any disturbance or variation in switching power with SPU
parameter = 4 or 5 (if Func.A and/or Func.B have value 7, the ratio
IN1/IN3 stored in C1A and/or C1b is calculated at MAN/AUTO
switching)
1 The setpoint is unchanged, the instrument adjusts to reach the
setpoint (local or remote).

(does not change with keys)
1 Power value is set to AM.P value.
Manual local: power can be increased or decreased via the
keys or digital inputs.
Manual remote: power assumes the percentage value of the manual
remote when it is brought to values less than or equal to AM.P.
2 The power value is unchanged and keeps the value it had in automatic
Manual local: power can be increased or decreased via the
keys or digital inputs.
Manual remote: power can be increased or decreased to the percentage
variation of manual remote.
3 Manual local: The power value is unchanged and keeps the value it had
in automatic. It can be increased or decreased via the keys or
digital inputs.
Manual remote: power assumes the percentage value of the manual
remote.

Switching modes between local
setpoint and remote setpoint
0 Immediate switching between local and remote setpoint
1 Switching with set gradient G.SP [digit/minute]
2 At switching from remote to local setpoint, the local setpoint value
assumes remote setpoint value.
3 At switching from local to remote setpoint, the variation takes place
with set gradient G.SP, at switching from remote to local setpoint the
local setpoint value assumes remote setpoint value.

+16 = setpoint gradient in [digit/sec].
Power On modes
(conditions set at power-up)
0 Operation at last memorized state (states of any digital inputs have
priority)
1 Automatic with local setpoint
2 Automatic with remote setpoint
3 Manual local; power value is set in parameter AM.P
4 Manual remote, the power value is the one of the remote input
5 Manual local with switching to automatic after first deactivation of
alarm 1 (AL1)
6 Manual remote with switching to automatic after first deactivation of
alarm 1 (AL1)
