FIGURE 2-8
Volt, Millivolt and milliamp Input
Make the volt, millivolt and milliamp connections as shown below. Use TB4 for thePen 1 input,
and TB5 for the Pen 2 input. Terminal 1 is positive and terminal 2 is negative. The milliamp
input requires the installation of an appropriate shunt resistor (ordered separately) between
terminals 1 and 2. Be sure that input conditioning jumpers are in the correct positions for the
input being connected. See Appendix A-1 (page 62).
NOTE: Fault Detection is not functional for 0-5V or 0-20mA inputs.
FIGURE 2-9
Remote Setpoint Input VDC , mADC
If Remote Setpoint option has been specified, make connections as shown. The remote
setpoint input may be selected as either 0 to 5 VDC or 1 to 5 VDC input in the Program mode
section. Make sure the configuration properly matches the input used. Use TB4 for Pen 1, and
TB5 for Pen 2 if Pen 2 is provided and specified with the Remote Setpoint option. Connect
the positive lead to terminal 4, and the negative lead to terminal 3 (Terminal 3 is the ground,
terminal 4 is the input, terminal 5 is 5 VDC.) If a 4 to 20 mADC remote setpoint is to be used,
the instrument remote setpoint input should be configured for 1 to 5VDC in the Program
mode, and a 250 ohm resistor should be installed across terminals 4 and 3. A 250 ohm
resistor is provided with the instrument, one per pen. The resistor(s) are shipped in the plastic
bag that is clipped to the inside of the instrument cover. This is the same bag that contains
the spare pen cartridge(s).
