Emerson Process Management 9110-00A, CI-9110 DC Power, Current Output to FSK Bi-State Transmitter

Page 38

CAUTION

When using the Regulator with a device that provides latching type outputs (output stays ON until turned OFF), the Raise/Lower inputs must be set for a pulse incremental signal. (see Section 3 - Board Setup). This will prevent the Regulator from driving full scale should the telemetry line open while in the middle of a Raise or Lower command. By using this configuration, the pressure output value will only change when input pulses are received.

Figure 4-6 - Current Output to FSK Bi-State Transmitter

4.6 4-20 mA CURENT OUTPUT

The current output of the Regulator can be used to drive a METATONE B, FSK Analog Transmitter as shown in Figure 4-6. The 4-20 mA current signal is referenced to signal common and flows through the loop resistor present at the input of the Analog Transmitter. The current signal modulates a tone carrier which communicates with an Analog Tone Receiver at the command site (not shown).

4.7 DC POWER

The Remote set Regulator is factory-shipped for 12 or 24 Vdc supply operation. Before power is applied, a check should be made to ensure that the Regulator type matches the supply source.

The dc supply source is wired to the Regulator in Figure 4-7. An earth ground must be provided for both the Regulator housing and the supply. The connection for the Regulator is made to the green grounding screw located inside the housing (see Section 2 - Installation for illustration).

WARNING

Metal enclosures and exposed metal parts of all electrical instruments and devices must be grounded to prevent accidental electrical shock. Grounding must be in accordance with latest OSHA rules and regulations pertaining to "Design Safety Standards For Electrical Systems."
