CONFIGURA TION 179
13.4.2.1 A OPX SETUP / A OP1/2/3 Dividing factor PINs 251 / 254 / 257
This factor is normally set to provide a maximum amplitude of 10 V for the terminal signal voltage. The PL/X
default 100.00 % voltage is 10.00V. Hence a dividing factor of 1.000 gives 10.00 V amplitude for 100.00 %
signals. This factor is arranged as a divider function to allow high gains if required, by dividing by numbers
less than 1.0000. This scaling takes place prior to the addition of an offset in the next windo w.
13.4.2.2 A OPX SETUP / A OP1/2/3 Offset PINs 252 / 255 / 258
Note 100.0 0% is equivalent to 10.00 V. Changing the divider factor will not affect the offset value.
13.4.2.3 A OPX SETUP / A OP1/2/3 Rectify mode enable PINs 253 / 256 / 259
13.4.2.4 A OPX SETUP / A OP1/2/3 Make output GET FROM source connection

Note. The function 260)SC OPE OP SELEC T described belo w uses A OP3. Any internal GETFROM connection
made to A OP3 is left intact but ignored by 260)SCOPE OP SELECT function.
