3.6 MASTER, version X or Y (NTC °C), for 1 or 2 control INPUTS
fig. 23
The
rgf300
version for temperature control inputs with
NTC
sensors is available in two
°C
scales:
MASTER X
with temperature scale
+10 to +60 °C
MASTER Y
with temperature scale
-20 to +20 °C.
The scale limit values for the Trimmer with
P3
Set-point calibration are inverted compared to the
current (
mA
) and voltage (
Vdc
) scales for the active sensors.
WARNING !
• The configuration with NTC temperature sensors is not compatible with other configurations.
It is not therefore possible to alter the position of the jumpers to pass from operation with NTC sensors to
operation with active sensors or control signals in mA or Vdc, nor to change the °C work field/scale of the
rgf regulator.
