The display PCB may be removed from the enclosure for bench calibration.  
Loop jumper must be installed on input signal PCB to maintain loop. Refer to  
Servicing display PCB outside the loop on page 9.  
WARNINGS:  
• To maintain hazardous area protection, the input signal must  
always be connected to the input signal PCB, and not directly to  
the display PCB.  
• Electrostatic hazard. Clean only with a moist cloth. Protect  
enclosure from exposure to chemical solvents and excessive  
ultraviolet (UV) light (such as sunlight).

Setup  
WARNINGS:  
• If any of the following operations are performed in the hazardous  
area, all appropriate hazardous area procedures must be  
followed.  
• To prevent damage to electronic components caused by  
electrostatic discharge, a grounding strap should be worn when  
servicing the display.  
For calibration, a calibrated current source and a screwdriver are required.  
Calibration connections  
To access the input terminals, remove the enclosure cover and the display PCB.  
1. Loosen the four screws on the enclosure cover and remove the cover.  
2. Completely loosen the left screw that holds the display PCB to the enclosure and  
loosen the right screw about four turns so the display PCB remains attached to the  
enclosure.  
3. Rotate the display PCB 90° to gain access to the input signal PCB.  
4. Next, connect a calibrated current source as shown in Calibrator connected to input  
signal PCB on page 6.  
Decimal point selection  
The decimal point jumper array is located in the lower right corner of the display PCB  
next to the display. It is labeled DP1, DP2, DP3.  
Place a jumper over both pins of DP1 for a display of 199.9, DP2 for 19.99, or DP3 for 1.999.  
Calibration  
LO and HI calibration controls are located to the left of the display (see Calibrator  
connected to input signal PCB on page 6).  
1. Apply a signal equal to 4 mA and adjust the LO control to display the desired reading.  
2. Apply a signal between 16 and 20 mA and adjust the HI control to display the desired  
reading.  
3. Complete the calibration procedure by making any minor adjustments to the LO and  
HI controls.  
Installation  
To install the meter, remove the display PCB from its enclosure and connect a ½" conduit  
fitting to the hole provided. Refer to Removing display PCB from the loop on page 9 for  
Page 8  
SITRANS RD100 – INSTRUCTION MANUAL  
7ML19985JU01  
 
further details. Wall mounting holes are located in each corner of the enclosure (see  
Mounting on page 4).  
Loop connections  
Disconnect power to the loop and install the meter as illustrated in Control loop  
connected to input signal PCB on page 6 and Removing display PCB from the loop on  
page 9. Replace the enclosure cover.  
Removing display PCB from the loop  
The display PCB and input signal PCB are connected together with one black and one red  
wire. The wires are soldered to the display PCB and connected to a screw terminal  
connector on the input signal PCB.  
1. Remove enclosure cover and the display PCB as described in steps 1 to 3 of  
Calibration connections on page 8.  
2. Install loop jumper over both pins to bypass display PCB and allow the signal to flow  
through the loop jumper. The display turns off when jumper is installed.  
3. Disconnect the black and red signal wires from the screw terminal connector.  
4. Loosen completely the right-side screw and lift display PCB from enclosure.  
CAUTION: Care should be taken to prevent static electricity from  
damaging the electronic circuitry.  
5. Restore enclosure cover to the base to prevent contamination of components.  
Restoring display PCB to the loop  
1. Loosen the four screws on the enclosure cover and remove the cover.  
2. Secure display PCB to enclosure using right-side screw; do not tighten screw to  
allow rotation of display PCB while accessing input signal PCB.  
3. Connect red wire to S+ terminal and black wire to S- terminal, as shown in  
Calibrator connected to input signal PCB on page 6.  
4. Remove loop jumper to allow the signal to flow through display PCB (save push-on  
jumper by placing over one pin only).  
5. Tighten screws holding display PCB and install enclosure cover.  
Servicing display PCB outside the loop  
Two modes of input signal allow the user to remove the display PCB for service without  
interrupting the loop as indicated above and operate the display PCB at another location  
in a non-hazardous area. The loop remains connected to the input signal PCB while the  
display PCB is absent for service. The user may operate the display PCB at another  
location by connecting a signal to “S+” and “S-” wires on the display PCB. Refer to  
Calibrator connected to display PCB on page 7.
