Calibrator connected to display PCB display PCB component side DP1 DP2 DP3 S+ S- calibrated current source 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.
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. 2. 3. 4.
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.
