CONNECTIONS. Connect electrical signal input to
I/P converter and calibrate if necessary. Refer to
paragraph 4-3 for calibration procedures. The
connections must be made by screw terminals. If the
I/P has pigtail leads instead of screw terminals, the
connection must be made at a tam&d block. Gage of
wire required is 18 gage signal wire. The signal that
will control the I/p should have a range of 4 to 20
mA at a voltage of 24 vdc.
