Resumen del manual


The pushbutton switch is used to jump the load. 1. Adjust input test circuit for 4.995 V on DMM #1. 2. DMM #2 should read 20 mA. If necessary, adjust pot R50 to correct. 3. Press load pushbutton while observing DMM #2. If current reading increases, adjust R49 CCW. If reading decreases, turn it CW. Repeat procedure until change is less than ±.02 mA. 4. Final reading should be 20 mA, ±.02 mA. If necessary, reset pot R50 and repeat procedure. 5. Calibration is complete. Restore unit to normal operating status. 5.9 PCB REFERENCE DRAWINGS Table 5-1 below provides part numbers and drawing references (Figures 5-4 through 5-7) for the printed circuit boards provided with the Remote Set Regulator.

Ranges: 4 - 20 mA dc or 1 - 5 Vdc Input Impedance: For 1 - 5 V > 330 K Ohms For 4 - 20 mA > 250 Ohms, ±0.1% Analog Fault Detector: Stepper Motor is cut off when AI < 0.8 V, ±0.1V 6.2 RAISE/LOWER INPUT MODEL Function: Uses Raise and Lower Inputs to set a pressure output signal. Input may be configured to accept a continuous ON/OFF dc signal or incrementing dc pulse signal. Input Characteristics: Opto-isolated and bi-polar. Limited to 47 V by metal oxide varistor (MOV). Types of Inputs Accepted: May be configured for continuous dc input signal (On or Off) or dc pulse incrementing signal. Continuous DC Input: Maximum dc input level is a function of the supply voltage as follows: 12V Model: 11 - 14 Vdc 24V Model: 22 - 28 Vdc DC Pulse Incrementing Input: Pulse rates adjustable from 0.110%/pulse to 1.830%/pulse. Pulse must be held in TRUE state for time period necessary for Regulator to reach the new output value. An input that changes state before completion of an operation will have its remaining pulse increment discarded. The next complete pulse starts a new increment. Input Impedance: For 12V Model: 1800 Ohms For 24V Model: 4300 Ohms Specifications 6-2 CI-9110 6.3 GUARD INPUT Enables or inhibits command signal input on both Analog and raise/Lower models. 6.4 ANALOG OUTPUT Function: Current feedback signal tracks the output of the Remote Set Regulator. Signal is typically used to telemeter pressure output value back to the command site. Range: 4 - 20 mA common ground type output Load Resistance: 380 Ohms Max. 6.5 ACCURACY - ANALOG MODELS Electrical Input to Pressure Output: ±5% of span Pressure output to Feedback: ±5% of span 6.6 ACCURACY - RAISE/LOWER MODELS Feedback Volts to Pressure Output: ±5% of span Pulse Input to Pressure Output: ±20% of span 6.7 DC POWER 12 Volt Model: 11 - 14 Vdc @ 0.35 A Max. 24 Volt Model: 22 - 28 Vdc @ 0.25 A Max. Fuse: 1 A, 250 Vdc, 3AG 6.8 STEPPER DRIVE MECHANISM Stepper Motor: Gearing from motor shaft to pressure regulator assembly results in approximately 22,000 incremental steps for 100% output range travel. Output Rate of Change: Full scale sweep adjustable from 1.8 to 69.4 minutes. Environmental Effects: ±1.0% Max. full scale per 50°F (28°C) Supply Voltage Effect: ±0.15% Max. full scale per 1 volt change CI-9110 6-3 Specifications Hysteresis: (Output to gauge) 0.5% of span Motor Protection: Adjustable mechanism limits restrict output for over and under range conditions. Automatic timeout prevents clutch wear. Power Failure: Mechanism maintains output pressure prior to loss or drop of supply voltage. 6.9 PRESSURE REGULATOR ASSEMBLY Output Ranges Offered: Range Factory Calibrated with 3 - 15 psig 20 psig supply 3 - 27 psig 30 psig supply 6 - 30 psig 35 psig supply Supply Pressure Range: Type Min. Max. Unit Supply Supply (psig) (psig) (psig) 3 - 15 20 100 3 - 27 30 100 6 - 30 35 100 Supply Pressure Effect: 0.1 psig Max. change in output for each 10 psig change of input. Connection: IN, OUT and VENT ports (1/4 Inch NPT) 6.10 INSTRUMENT ENCLOSURE Type of Case: Weatherproof and explosion proof. Cast aluminum with gasketed screw-on cover. Gray epoxy finish. Meets NEMA-3 specifications General Dimensions: 6 inch (152.4 mm) diameter 7 inch (176.8 mm) length Weight: 10 pounds (4.54 kg) Mounting Options: In-line pressure pipe or 2 inch pipe bracket 6.11 ENVIRONMENTAL Temperature Limits: -2...
