TM 10-4320-344-24Ensure that all wires and external connections are disconnected from processcontrol device prior to performing this test. Failure to disconnect allexternal connections may resulting damage to process control device.Refer to figure 2-89 for location of identified terminals in the followings t e p s.a.b .c .d.e .f .g.Ensure all external connections and wires leading to and from process controldevice are disconnected.Connect 12 or 24 VDC power source to terminals 1 (+) and 2 (-).A 10K resistor must not be connected if low or high output impedance is used.If low-signed selected output is used, connect 10K resistor from terminal 16to terminal 10.If high-signed select setting is selected, connect 10K ohm resistor fromterminal 16 to terminal 17.Set droop gain and low-limit potentiometers to full counter-clockwise (CCW)p o s i t i o n.Set high-limit direct control point and inverse control point potentiometersto fully clockwise (CW) position.Measure output voltage from terminal 16 (+) to terminal 17 (-) to verify thatoutput voltage is -0.5 ± 1.0 VDC.If process control device output voltage ramps properly but process controldevice is still operating incorrectly, check system for correct wiring. Examineother components in system for correct operation. Verify that input sensingdevice is wired to correct terminals necessary for the desired controllingaction (inverse or direct).h .Quickly rotate inverse control point adjustment to fully CCW position.Output should slowly ramp up to 9.4 ± 2.0 VDC. If the output is not withinthis range, the unit is defective.i .Replace defective process control device.2.16.33.4 Installation.Install wires on screw located at bottom right mounting point of processcontrol device.a .Position process control device (Figure 2-88, 3) on control panel (8) andsecure with four screws (7), new lock washers (6), and nuts (5). Remove anddiscard tags.b .Install wires (2) on process control device (3) with screws (1). Remove anddiscard tags.2-219NOTENOTENOTENOTE
