Y2 nnn Setting, User Set Fixed Analogue Output level in an error mode.
The unit will output a fixed Voltage (T1 setting) or fixed milli-amp (T5/T3 settings) signal
on the analogue output with a value depending on the Y2 nnn setting.
nnn is user-selectable value between 000 to 200.
Scale factor for fixed voltage output is 0.025V.
Scale factor for fixed current output is 0.1mA.
Therefore:-
nnn value = Required fixed Error Voltage/0.025 (voltage output setting T1).
nnn value = Required fixed Error Current/0.1 (current output settings T5/T3).
Under data error conditions then by setting the unit for Y2 configuration the analogue
outputs will read a user set error value for the period of the error condition as follows with
the unit in Polar Continuous Output and 0-5v (T1), 0-20mA (T5) and 4-20mA (T3).

Y3 nnn setting Analogue Output cycles to a user determined level in an error mode.
Under data error conditions the analogue outputs will switch back and forth between a user
determined level (voltage or current) with a value depending on the Y3 nnn setting.
nnn is user-selectable value between 000 to 200.
Scale factor for upper voltage output is 0.025V.
Scale factor for fixed current output is 0.1mA.
Therefore:-
nnn value = Required Error Voltage/0.025 (voltage output setting T1).
nnn value = Required Error Current/0.1 (current output settings T5/T3).
The following table summarises the above reporting conditions with Analogue Outputs set
