mA output 1?
mA output 2?
mA output 3?
mA output 4? Load error
The mA output cannot drive its mA
output current through the
connected current loop (400 Ohm
at 20 mA max.). Check whether the mA signal is
required at all (e.g. for plotter). If not,
switch off the output signal in the
"INPUTS/OUTPUTS" menu (analog
output).
Check mA signal cable for interruption
Resistance in the current loop
> 400 Ohm Reset the respective bridge on the
plug-in module "mA outputs":
L:< 400 Ohm, H:< 1000 Ohm
Temperature? Interruption in the
temperaturesensor or cable Check multi-sensor and cable
Setpoint mod1
Setpoint mod2 Setpoint error in module 1 or 2
Due to modification of the
measuring range, the controller
setpoint
is outside the measuring range. Reset the controller setpoint or adjust
