1.1 DESCRIPTION 1.1 DESCRIPTION The JD series Differential Pressure Switch is an all-electronic, solid-state instrument that complies with all applicable USPH codes. The instrument senses raw and pasteurized product pressures and displays them in bright 1/2" LED numerals. The differential is calcu- lated and displayed on the bargraph as is the adjustable setpoint. -

The connec- tion terminal numbering of 1-5 (shown) corresponds to general industry numbering standards. -
Page 8: Power Supply
2.3.2 Power Supply The HTST is powered by either 120 or 240 VAC, 50-60Hz. WARNING: Check the instrument nameplate for the specific rating before connecting to power source. Current draw is less than 1/4 amp, so 18 AWG, 2-conductor with ground instrument wire is sufficient. -

Page 10: Transmitter Signal Connections
2.3.5 Transmitter Signal Connections The Instrument is shipped with sensors pre-wired and calibrated. In the event that the wires are removed for installation, they should be re-attached as shown below. Access to the terminal blocks is gained by removal of the two right side thumbscrews on the display board, and pivoting the board away. -
Page 11: Ma Output Wiring
2.3.6 4-20 mA Output Wiring If utilizing the 4-20 mA retransmission outputs, they can be wired as shown below. NOTE: These inputs are non-isolated and cannot be wired with one leg grounded as in some programmable controllers designed for single ended inputs. NOTE: If interface boards are to be removed to facilitate wiring, turn power off before pulling boards. -

The test is designed to check the accuracy of both sensors, accuracy of the differential indicator, and operation of the differen- tial switch and relay. -
Page 15: Calibration Adjustments
Procedure Checking Pressure Readings at Zero: Loosen the process connection at both pressure sensors and allow any fluid to drain through the loose connections. Both the raw and pasteurized digital displays should read zero. To adjust, open the instrument cover and turn the blue potentiometer ("pot") labeled "o"... - Page 16 FIGURE 13 CALIBRATION ADJUSTMENT LOCATIONS FIGURE 13 CALIBRATION ADJUSTMENT LOCATIONS FIGURE 13 CALIBRATION ADJUSTMENT LOCATIONS FIGURE 13 CALIBRATION ADJUSTMENT LOCATIONS FIGURE 13 CALIBRATION ADJUSTMENT LOCATIONS High Pressure K1 Relay Setpoint Adjust Open/Closed High Pressure Differential Bargraph Adjust Setpoint Adjust High Pressure Relay State Past Display Raw Display...

4.3 CALIBRATION PROCEDURE 4.3 CALIBRATION PROCEDURE 4.3 CALIBRATION PROCEDURE 4.3 CALIBRATION PROCEDURE 4.3 CALIBRATION PROCEDURE Taking care not to dent the sensor diaphragms, remove the sensors from the process and connect to the test fixture. Locate the 0-1 VDC test points B, C & D as shown in Figure 13. Connect the Black (-) meter lead to TP C, and the Red (+) meter to TP B. -
Page 18: Section 5 - Troubleshooting
The formula for determining proper output at any known pressure or differential is: Differential Zero and Span adjustments for these outputs are located as shown in Figure 9. Zero for the output should be adjusted during the final zero check in Section 4.3 and span during the final span check in 4.3. - Page 19 Significant Error in Pressure Readings Cause: Loose or improperly inserted interface boards Caution: Never remove or reinsert interface boards with power "on". Turn off power or remove fuse. Action: Open case door and push interface boards firmly into slide socket (see Figure 13).
- Page 20 Several voltage (D.C.) checks can be easily made to determine sensor and circuit board functioning. Checks are first made at the input terminal block to check excitation voltage and sensor outputs. These are followed by display board voltage checks to verify interface card functioning and calibration.
