ID 222
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
1
Options:
0 = 0 - 20 mA; or
1 = 0 - 10 V.
Description:
Defines the analog input mode to current or voltage the DIP switches on control board will need to be set to the same mode as this
parameter.
*DM1 CN5 terminals 8 and 9 for current or voltage, also need to set DIP switches SW2 2 and 3 on control board, near the RJ45 port.
DIP switches SW2 2 ON and 3 OFF for voltage.
Current mode, if using the +10 V supply on CN5 terminals 13 of the DM1 / DM1 Pro, it will require DIP switches SW2 2 and 3 on to
complete the current loop. When doing a current loop with an external supply, the DIP switches SW2 2 off and 3 on.
