Signal:u (Type And Polarity Of The Output Signal); Sys_Range (Working Stroke); Signal (Type Of Input) - W.E.ST. POS-124-U-PFN Technical Documentation Manual

SIGNAL:U (Type and polarity of the output signal)

Command
SIGNAL_1:U
SIGNAL_2:U
This command is used to define the output signal (voltage or current) and to change the polarity
Differential output ± 100 % corresponds with ± 10 V (0... 10 V at PIN 15 and PIN 16 or PIN 19 and PIN 20).
Current output ± 100 % corresponds with 4... 20 mA (PIN 15 to PIN 12 or PIN 19 to PIN 18). 12 mA (0 %) =
center point of the valve.
An output current of << 4 mA indicates an error and the module is disabled. The current input of
the proportional valves should be monitored by the valve. The valve have to be deactivated in
case of < 4 mA input signal. Otherwise the EOUT command can be used to get a defined output
signal.

SYS_RANGE (Working stroke)

Command
SYS_RANGE_1
SYS_RANGE_2
This command defines the full stroke, which corresponds to 100 % of the input signal. If the demand is set
incorrectly, this leads to incorrect system settings, and the dependent parameters such as speed and gain
cannot be calculated correctly.

SIGNAL (Type of input)

Command
SIGNAL_1:X
SIGNAL_2:X
This command can be used to change the type of input signal (voltages or current) and to define the direc-
tion of the signal. This command is available for the analogue feedback inputs.
OFF= Deactivation of the input.

The older POL command is removed.
